Pairing Up for the Party Season: The Chemistry Behind the Perfect Food and Wine Pairings

The party season is approaching, and once again chemists have offered the world a gift: the science behind the perfect food and wine pairings. For those who would like to progress beyond “red with steak” and “white with fish,”  there is now peer-reviewed research that may help inform a nuanced and elegant choice for every meal.

Whether you are a seasoned connoisseur or an enthusiastic amateur, you are likely well aware that the taste of wine can differ depending on the types of foods you consume with it. Despite an abundance of food pairing hypotheses over the years, there has traditionally been no supporting evidence or studies to examine the rationale, and many remained skeptical that there would be any scientific basis to support individual sensory experiences or preferences.

But just in time for your holiday menu planning, recent research has revealed some of the underlying chemistry behind why some wines and foods (cheese, anyone?) seem to be made for each other—and why some pairings may not work as harmoniously as others.1

The Tannin Tamer: How Lipids Work to Balance Bitterness

Wine, along with many other food products, contains both volatile and non-volatile compounds. Volatile compounds such as thiols contribute to a wine’s aroma, but it is the non-volatile substances that are responsible for taste and mouthfeel. These compounds may be affected by components such as alcohol, sugar, acid, polysaccharides, nucleic acids, and—most notably—phenolic compounds such as tannins, which are commonly associated with the bitterness, astringency, and complexity of red wine.2,3

Many flavor precursors can also derive from other ingredients such as yeasts, as well as containers and vessels—for example, traditional oak barrels.4 However, there is one previously overlooked chemical component that could hold the key to understanding more subtle aspects of wine flavor: lipids.

To further understand the interaction between lipids and wine tannins—and potentially uncover why wine and cheese go so well together—researchers from the University of Bordeaux (in the famous wine region of France) conducted a twofold approach using both biophysical methods and sensory analysis.1

First, they observed the behavior of lipids in an oil–water emulsion after mixing in catechin, a primary component of grape tannins. This resulted in the lipid droplets absorbing the catechin at the membrane surface, increasing in size and producing a “creaming” effect in the upper phase of the emulsion.

These molecular findings were reinforced by the sensory analysis which demonstrated that certain dietary oils, such as grapeseed oil, decreased or even eliminated perceived tannin astringency, while others like olive oil made the wine taste fruity instead of bitter.

This study further validates lipids—such as the fats in cheese, meat, and other charcuterie board favorites—as crucial molecular agents that can both soften the bitter taste of wine and enhance its flavor profile by attracting tannins to their surfaces (and away from your bitter taste receptors).

Lipids are also naturally present within wine itself, although in very low concentrations. A team at Oregon State University (also in a prominent wine region of the U.S.) examined how lipids in wine contribute to taste and mouthfeel by adding various food-grade lipids to a model wine solution. Of the lipids tested, phospholipids most noticeably contributed to an increase in perceived viscosity while also masking bitterness.5

Further research in this area is needed to better understand the full range of effects of lipids on taste and mouthfeel—but there is great potential for winemakers to one day successfully alter lipid composition during the processing phase, yielding wines that are naturally less bitter and more appealing to consumers who desire softer, more mellow flavors.

Red vs. White: Ironing Out the Differences 

So, is there a scientific basis for the original red/white divide when it comes to seafood? Well, possibly. It turns out red wine has more ferrous (iron(II)-containing) ions compared to white wine, as a function of the materials used in the processing. Controlled experiments showed that wines higher in iron can promote lipid oxidation of the unsaturated fatty acids found in fish and seafood, generating an unpleasant associated retronasal smell.

Although iron vessels are less often used in modern processes for red wine, there is no easy way to gauge a wine’s iron content without tasting it first. There are numerous factors beyond wine type that can influence iron content—from soil composition to fermentation processes—making it tricky for a consumer to identify any potential unsavory food pairings just by looking at the label alone.6

But iron-heavy red wines aren’t the only culprit when it comes to unpleasant taste perceptions associated with seafood pairings. Researchers in Japan demonstrated that white wines containing sulfur dioxide (SO2), a sulfite commonly used for wine preservation, resulted in an “off-odor” and undesirable taste when paired with seafood containing high amounts of polyunsaturated fatty acids.7

After adding DHA—a polyunsaturated fat present in seafoods such as dried squid and mackerel—to various white wine and sake samples, the team observed accelerated rates of DHA oxidation in the SO2-heavy wines, resulting in a malodorous smell and taste.

The scientists speculate that the widely followed “white wine with fish” tradition may be more accurately applied to seafood pairings such as whitefish, shrimp, crab, and other options that contain lower levels of these fatty acids. Even so, it is now easier than ever to find sulfite-free wines—which, in addition to those with sulfite sensitivities, may be a preferred option for consumers who want to ensure a delicious white wine pairing regardless of fish or seafood choice.

A Matter of Taste

Understanding the science behind wine’s interaction with various compounds on a molecular level can help to better inform many components of wine culture, from perfect food pairings at your next holiday gathering to modifications in grape cultivation and processing. But as the sensory analyses in these studies show, everyone has different preferences and perceptions when it comes to flavor, taste, and mouthfeel—and wine is no exception. Ultimately, if it tastes good to you, go with it. Cheers!

Greener Methods for Cleaner Water

Water, water everywhere…but is it clean enough to drink? For more than one-third of the world’s population, the answer is no.1 Access to clean drinking water is currently one of the most challenging global issues, exacerbated by climate change, increasing water scarcity, population growth, demographic changes, and continued urbanization. But scientists are now harnessing the power of the sun to effectively and sustainably turn salty ocean water into a clean, drinkable resource. 

Advances in Solar-Powered Desalination Technology

A Paper-Based Answer to Salt Accumulation

While the majority of the earth’s surface is covered by water, more than 97% is found in the oceans and cannot be consumed due to its high salinity. But chemists have been working to address the global water crisis by developing more efficient and environmentally sustainable seawater desalination techniques.

Solar-powered desalination is steadily becoming a leading force in battling global water scarcity, and there is a strong drive to advance solar desalination methods for more widespread applications in sustainable clean water production. Most traditional solar evaporation systems operate using thermal conduction, but the biggest challenge for these evaporators is excessive salt accumulation on the absorption layer, which hinders evaporation efficiency and makes the devices difficult to clean and maintain.

However, research recently published in ACS Applied Materials & Interfaces demonstrates a novel solution in the form of a paper-based thermal radiation-enabled evaporation system (TREES).2 This system uses a contactless configuration consisting of a vertical evaporation wall made of filter paper, which surrounds a thermally insulated bottom solar absorber constructed from surface-inked wood and polystyrene foam.

The evaporation wall can efficiently capture thermal energy from the solar absorber while also gaining energy from the warmer environment, enhancing the evaporation process. The wall is also unique in its ability to efficiently collect the salt on its exterior and, through energy down-conversion, enable water to serve as its own absorber and create a dynamic evaporation front from the accumulated salt layer. Furthermore, since the TREES system is contactless, the salt layer does not accumulate on the bottom absorber surface.

After testing the TREES system outdoors for eight consecutive days, the researchers reported that it can enhance evaporation by more than 1000% compared to traditional systems. By overcoming the salt accumulation challenge and improving the evaporation process, TREES exhibits tremendous potential as a driver of next-generation desalination technology. Watch a video of TREES in action.

Doing Double Duty with Hydrogel

Another desalination approach published in ACS ES&T Water uses a hydrogel platform to produce fresh water from both the ocean and the atmosphere.3 Salt accumulation presents a challenge here as well—hydrogel-based solar steam generators currently used for seawater desalination are easily clogged and dirtied by excess salt deposits.

Despite their obstructive nature, researchers observed that these salts could be quite useful for absorbing water from the atmosphere, and they worked to develop a versatile solar-thermal hydrogel (TA-Fe@PAM) that could integrate oceanic desalination and atmospheric water collection within a singular device.

The team constructed the TA-Fe@PAM hydrogel by embedding a tannin-iron (TA-Fe) photothermal complex into a polyacrylamide (PAM) hydrogel system. The hydrogel’s porous nature allowed for efficient photothermal conversion and water transport while effectively trapping large amounts of deliquescent salts during rapid solar desalination. The hydrogel containing the incorporated salts (DS-TA-Fe@PAM) was then dried and tested for atmospheric water collection performance. The DS-TA-Fe@PAM hydrogel was able to successfully capture atmospheric water vapor and then release almost all of the water it had collected.

Finally, the team tested DS-TA-Fe@PAM within a device made from cheap, easy-to-assemble household materials, and it again demonstrated efficient water harvesting and release. This is especially promising for use in developing countries and low-resource settings where it is difficult to regularly access clean water.

Taken together, these new findings provide novel insights into the design of next-generation salt-harvesting solar evaporators and take a step further to advance their applications in sustainable desalination.

Food Packaging is (Naturally) Getting Smarter

Food packaging and waste are two key issues in the race to address climate change—and they are often one and the same. But several recent studies present innovative solutions for intelligent, sustainable food packaging alternatives to petroleum-based plastics and synthetic dyes.

The food we eat has a dramatic impact on the planet. Much attention is given to the ecological consequences of mass farming, agriculture, and food production processes. But part of the challenge stems from two associated problems: increasing levels of food waste, and the ubiquitous use of plastics in food packaging. In fact, food packaging is the third largest global industry and the single-largest contributor to solid waste.1-3

Since most food packaging is either disposed of improperly or cannot be recycled at all, the damage caused by plastic debris and microplastics is also an important part of the conversation.2 Yet packaging is an essential need for many foods, preventing contamination and extending shelf life. This role in reducing food waste is crucial, since it is estimated that 17% of total global food production is wasted.3

Some argue that removing packaging altogether would result in a heavier dependence on refrigeration, which could drive the problem in a different way by further increasing energy usage and greenhouse gas emissions. So how can we address this issue without compromising hygiene and food quality?

Progress Toward Biodegradable Active Packaging

One proposed solution is through active packaging technology, which—when triggered by changes either to the product itself or to outside environmental conditions—works to release active compounds or isolate gaseous emissions within the package in order to extend freshness.1 Although the concept of active packaging has existed since the early 1900s, significant technological innovations have only begun to gain traction in recent years.

Lately, research in the field has been focusing on exclusively using biodegradable and biocompatible materials for active packaging technology. Options for natural antimicrobial biopolymers in active release packaging include corn starch, collagen, cellulose, and chitosan.1,4 Unfortunately, these biopolymers often have weaker material properties—such as mechanical strength and thermal stability—compared to conventional plastics, which must be improved upon before bio-based active packaging can be a safe, widely accepted solution.

Natural active agents, such as polyphenols from tea or essential oils from clove, marjoram, or thyme, may also be used as antimicrobials.1 Work is ongoing to ensure that the release of these active compounds from packaging can be strictly controlled in order to adhere to food safety regulations—and to ensure they do not affect the smell or taste of the food. Here, the food industry may borrow from medicine, where controlled-release drugs have become the norm in many therapeutic areas. This could mean it is possible to build a controlled-release food packaging environment where natural antimicrobials are induced by external stimuli such as heat or pH. And speaking of pH…

Giving New Meaning to Food Coloring

Another review in ACS Food Science & Technology also highlights more natural approaches to intelligent food packaging, focusing specifically on developments in pH-responsive color indicator technology.5 Color indicators on food packages have gained significant popularity in recent years, making it easier than ever for consumers to quickly assess the pH levels and freshness of foods with shorter shelf lives such as meats, dairy products, and seafood. But almost all current commercial pH indicators use synthetic dyes that could pose great health and safety risks if leaked from the packaging into the food itself.

As a solution, scientists have begun developing new color indicators made from pH-responsive natural colorants such as anthocyanins (found in produce and flowers); curcumin6 (derived from turmeric); alizarin and shikonin (root-derived); and betalains (found in beets). So far, indicators using these natural colorants have performed successfully on packaging for various animal-based food products. Despite their incredible potential, more research and testing must be conducted to further strengthen properties such as pH sensitivity and microbial marker detection before these natural colorant-based indicators make it to your local grocery store.

Many countries show signs of a desire to move towards reusable, recyclable, or compostable packaging, and the development of biodegradable packaging that can compete with plastics on a commercial level is fundamental to this revolution. To date, there have been few scalable successes in the field. But with the problems underpinning the need for sustainable and smart food packaging only growing, it is surely just a matter of time before the chemistry happening in the lab becomes mainstream.

Semiconductors: The Building Blocks of Modern Technology

The global semiconductor industry is on the rise, with the potential to grow into a trillion-dollar industry by the end of the decade. In tandem, scientists continue to advance the field with quality research in semiconductor technology and applications. Here, we explore recent advances in semiconductor research across ACS Publications journals.

Tiny Powerhouses

Semiconductors are a class of crystalline solids whose electrical conductivity exists between that of a conductor, such as aluminum or copper, and an insulator, such as ceramic or glass—hence their “semi” conductive nature.1 These diverse substances, including two-dimensional (2D) materials, optoelectronics, and optical devices, have become the fundamental components of modern electronic technology.

Progress Toward Next-Generation Devices

In addition to silicon, novel materials such as graphene also have a high potential for applications as semiconductors in electronic devices. However, their high contact resistance makes them susceptible to overheating, and this limits their practical applications. Some scientists have begun investigating various options to lower the contact resistance, making 2D semiconductors a promising candidate for broader use in electronics.2

Some 2D semiconductor materials have recently been shown to exhibit magnetic properties, which could make them extremely useful for next-generation spintronic devices and information technology, such as logic circuits that utilize the spin interactions of electrons. By applying magnetic and other enhanced properties of certain semiconductors, spintronic devices could reduce energy consumption while increasing processing capabilities, making them a viable alternative to traditional electronics.3 To enhance these magnetic properties, one study explores doping suitable magnetic materials into host semiconductors at room temperature.3 Others are examining strategies to develop more high-temperature 2D magnetic semiconductors that could also one day be widely used in spintronics applications.4

The role of semiconductors in optoelectronic technology and applications has grown significantly in recent years. Semiconductor nanocrystals have displayed great potential in optoelectronics applications such as light-emitting diodes and lasers5, and organic–inorganic hybrid semiconductors such as organometal halide perovskites are also encouraging candidates for next-generation optoelectronics.6

A (Machine) Learning Process

Machine Learning (ML) is a growing field that has transformed research processes across various industries, including semiconductor production. For example, developing new semiconductors with high thermal conductivity may aid in heat management and energy conservation for device cooling—and ML algorithms can rapidly and accurately generate screenings to predict different semiconductor material properties, evaluate their potential applications, and create simulation models for extreme conditions.7

A recent study in ACS Applied Nano Materials describes a method for deep-learning-based microscopic imagery deblurring (MID), which helps to more accurately identify 2D semiconductors and may be useful in the industrial manufacturing process.8

Powering Renewable Energy Sources

Outside of the electronics industry, another important area of interest is the powerful role of semiconductors in sustainable energy generation. Researchers recently reported on a new type of semiconductor alloy “nanoflower” with great potential for use in water splitting and hydrogen production.9

Harnessing the power of the sun is no simple task, but semiconductors are also proving themselves essential for the future of solar energy conversion. The growing demand for effective yet inexpensive photovoltaic materials has prompted some to begin exploring alternative semiconductor options—such as copper sulfide (CuS), which could have great success in improving the stability and photoconversion efficiency in perovskite solar cells.10

Another study describes a strategy for improving perovskite solar cell performance by introducing 2D material films or semiconducting additives to better balance the charge transport, or the flow of electric current through the solar cell.11

Semiconductors are everywhere in our daily lives, and their impact continues to grow across a multitude of industries and applications. From driving the performance of next-generation electronics to improving technologies for a more sustainable future, these tiny powerhouses are vital for keeping the modern world running.

Library Life: Interview with Northwestern University Librarian Elsa Alvaro

Elsa Alvaro

Elsa Alvaro is Head of Academic Engagement and the Librarian for Chemistry and Chemical and Biological Engineering at the Northwestern University Libraries.

Tell me about your current role:

My job as Head of Academic Engagement involves connecting the Northwestern community with the library’s collections, services, and expertise; overseeing two of Northwestern’s most notable libraries, the Transportation Library and the Herskovits Library of African Studies; and supporting student success connected to the library in a variety of ways, from directing orientation programs for undergraduate and graduate students to managing technology-rich spaces in which students can collaborate, learn and create. I am also the Librarian for Chemistry and Chemical and Biological Engineering.

What is your background?

I am originally from Spain and have a PhD in Chemistry. After obtaining my postdoc at the University of Illinois at Urbana-Champaign, I decided to pursue a degree in Library Science. It was at that time that I was awarded the ACS Division of Chemical Information Lucille Wert award, which started my involvement with CINF. I joined Northwestern as a chemistry librarian in 2013 and in 2019, I advanced to a leadership position in the library, becoming Head of Academic Engagement.

How do you help to address challenges faced by your institution’s students and faculty?

By putting librarians at the heart of academic life! We are an indispensable thread in the academic fabric.

For students, we do that by acknowledging the many different facets that define their experience at Northwestern University; those facets are opportunities to help students succeed. For example, if you are a chemistry major, we have a subject librarian specializing in your field who can help you discover the resources you need for rigorous research. If you are conducting undergraduate research, we have you covered there, too; we offer a summer grant for undergraduate students and a librarian works with the Office of Undergraduate Research to make sure we are addressing your unique concerns. For those who are studying abroad or interested in entrepreneurship, we have partnerships, tools, and resources to support those needs. Our engagement efforts extend to other aspects of the student experience, including new student programs and orientations, and end of term programming to support student well-being.

What are some trends that you are observing in the library world right now?

Academic libraries preserve, produce and provide access to knowledge. But we do not live in a bubble – our mission is connected to advancing research, teaching and learning at our institutions. That means that trends and challenges that impact universities, researchers, and society in general, are going to influence and shape our work. In the past years we have seen an increase in openness in the communication of research; and we are also observing that more fields are embracing AI and machine learning. Those trends have implications for us, including making available the work of our institutions (though licensing agreements, but also by being publishers), and the need to have a robust digital strategy and infrastructure.

As a result of the pandemic and understanding that the library is a workplace, one important current issue is how to be an equitable and inclusive community in which all library workers have the support to succeed in their roles.

What areas of interest are you focused on right now? 

My background as a chemist and a researcher strongly influences my approach to my job as librarian. I’m always looking forward to challenges, and I love to develop new programs to address gaps or unmet needs. For example, we are launching a new service to support systematic reviews and other types of evidence syntheses; this type of reviews is common in fields such as medical research but not so much in other disciplines. I am interested in bridging that gap, for instance by providing workshops and consultations in different aspects of the review process, and collaborating with researchers in projects.

You were also the chair of ACS’s Chemical Information (CINF) division in 2019. What was that like?

It was truly terrific. The experiences, opportunities and connections that I got through CINF have been key in my professional career, so I was honored and delighted to serve as chair. CINF is unique in the way it brings together informatics, librarianship, and data expertise in one community. Also, CINF officers and volunteers are a welcoming, talented, and supportive group of people, and a joy to work with. I was pleased that we engaged in strategic planning during my tenure.

A very important question: Who is your favorite scientist?

My spouse. Hands down. He is a theoretical physicist who works in neuromorphic computing and materials growth. Neuromorphic computing is a computer engineering approach that models and develops computing devices inspired by the human brain.

What is a fun fact about Northwestern University?

In 1921, Nobel Prize-winning chemist Marie Curie visited Northwestern University with her daughter to receive an honorary degree. During her visit, 100 area women coordinated a fundraising campaign and raised $100,000 (this would be over $1.4 million today!) to allow Madame Curie to purchase one gram of radium to continue her studies.

Neurotoxicity: Challenges and Chemistry

A recent Virtual Special Issue in ACS Chemical Neuroscience and Chemical Research in Toxicology focuses on cross-disciplinary strategies to address the many challenges embedded in the field of neurotoxicity.

Read the Virtual Special Issue Online

Defining Neurotoxicity: An Ongoing Challenge

Our bodies are continuously exposed to toxic chemicals—both natural and synthetic—that can negatively impact many physiological functions.1 Neurotoxicity can result from exposure to classic contaminants such as heavy metals and pesticides, as well as less understood compounds including food additives, packaging, personal care products, industrial solvents, and even medicine coatings. Exposure has increased to the point where all children are now born pre-polluted with hundreds of synthetic chemicals in their bodies. Many of these substances still need to be identified, let alone evaluated for potential neurotoxicity.1  

Given the multitude of contaminants affecting the nervous system and the complexity of possible measurements, it has been challenging for toxicologists to fully define what neurotoxicity really means.1 Although there is growing consensus that exposure to such chemicals is significantly hazardous to our health, we still lack a clear understanding of the relationships between certain environmental drivers and the ways in which they manifest in the nervous system.

A Virtual Special Issue in ACS Chemical Neuroscience and Chemical Research in Toxicology includes 15 recent papers demonstrating novel approaches and cross-disciplinary collaborations that may aid in advancing understanding and addressing challenges in the field.

Plant-Based Problems (and Protection)

Acrylamide (ACR) is a neurotoxicant produced by the high-temperature frying and baking of plant-based foods and found in carbohydrate-rich items such as fried potatoes, chocolate, cereals, and bread. One study examines the effects of repeated low-dose exposure to ACR with evidence of disrupted PERK signaling, shedding light on a possible mechanism for impaired memory and cognitive deficits.2 This work is significant because many chemicals such as ACR are known to be toxic at high doses, but understanding how the brain is vulnerable to low-dose exposure is broadly informative.

Other plant compounds seem to be more protective – including fustin, a phytogenic flavonol with the potential to protect against cognitive impairment following low-dose exposure to streptozotocin, a neurotoxicant that is also potently diabetogenic.3

Is Your Medicine Doing More Harm Than Good?

Food ingestion is not the only route of entry for toxins. Some commonly used medicines can have adverse effects on the central nervous system—for example, Cefepime, a common antibiotic used to treat a variety of infections, has been linked to side effects including reduced consciousness, confusion, and various anxiety-like behaviors.1,4

Another study reports that current antiseizure medications are effective in only 60%–70%  of patients, and development of new treatments has been limited by various—and potentially life-threatening—side effects.5 The researchers found, however, that new benzo[d]isoxazole derivatives display anticonvulsant activity by selectively blocking voltage-gated sodium channel NaV1.1, which provides good alternatives for antiseizure drugs in the future.5

The Dangers of Pesticide Exposure

Chronic pesticide exposure might result in oxidative stress, inflammatory reactions, and mitochondrial dysfunction.6 Exposure to the herbicide paraquat not only compromises lung, liver, and kidney function but has also been associated with cancer.7 However, new research suggests citric acid-sourced carbon quantum dots (Cit-CQDs) as a potentially viable biobased nanomaterial, made using environmentally friendly methods, for intervention in neurodegenerative disorders.8

Advances in Neurotoxicity Testing

One key challenge in the field remains the ability to test for neurotoxicity. Acute neurotoxicity that results in death or severe impairment is easily measured in the laboratory or clinical setting, but subtle effects resulting from exposure during a sensitive development period—or from chronic or cumulative exposure—are far more difficult to assess.1

One study shows how zebrafish represent an economical alternative to rodents for developmental neurotoxicity testing.9 Other new research suggests toxicity can be measured using fluorescent false neurotransmitters, allowing visualization of vesicular packaging at baseline levels, and following pharmacological and toxicological manipulations.10

The Special Issue also includes the first in vivo evidence to support the role of dopaminergic toxins in Parkinson’s disease (PD) using Caenorhabditis elegans models. The results suggest that some neurotoxins known to cause PD-related symptoms may be part of a broader group of chemicals that, if commonly present in laboratory or industrial settings, could have a detrimental impact on public health and safety.11

Paving the Way for Progress and Prevention

Ensuring that chemicals in use are as nontoxic as possible is essential for the long-term wellbeing of future generations and our planet. Ultimately, researchers agree there is an essential need for greater cross-disciplinary collaboration between neuroscientists, toxicologists, and chemists to advance the field.
