Understanding the biochemistry of ingredients and taste can improve flavor and texture

Explaining why salt should be used to season food early in the cooking process

Experiments involving the same dishes, with salt added at the start of cooking versus at the end, have been shown to yield drastically different taste outcomes because salt takes time to diffuse into foods, particularly vegetables, whose cells are surrounded by cellular membranes and walls. Salting at the end will produce a concentrated surface coating, rather than even seasoning.

A collection of molecular gastronomy techniques, from flavored air to turning oils into powder

Soy lecithin can be blended with flavored mixtures, such as herbs and Parmesan, to produce edible bubbles, which can be frozen into a solid foam. Maltodextrin can be combined with liquid fats in a food processor to create light, flavorful powders.

The importance of volatile aroma compounds in the flavor quality of food

Processes such as air movement and heating cause food to lose aroma molecules, which studies have shown play a major role in our sense of taste. While losing these molecules to the environment leaves fewer to be processed during consumption to intensify flavor, it can also produce previously nonexistent aroma compounds or release previously trapped ones, altering or enhancing the food's flavor.

How texture affects taste

Texture is the brain's interpretation of several sensations, including pressure, as registered by our teeth, tongue, and finger tips, and sound, as recorded by our ears. Texture also speaks to food particle sizes—smaller than 35 microns contributes to the sensation of creamy—and the balance between flavor and mouth time, such as the crunch of a crispy chip or the bounce of a chewy caramel.

Eggshell color doesn't indicate taste or superiority

Brown, white, and blue eggs taste and cook identically. Despite popular notions that brown eggs are superior, the shell color reflects the genetics of the hen alone. What actually determines egg quality is freshness and the diet of the hen (where grass and leafy greens lead to denser yolks). And freshness can go both ways: older eggs peel more easily than fresh ones.

Umami synergy—combining glutamates and nucleotides—can amplify a meal

While glutamates are known for triggering the umami taste through specific taste receptors, nucleotides like IMP and GMP can bind alongside glutamates to enhance the receptor's response. This union explains why certain classic food combinations like bacon and eggs taste exceptionally savory.

Chemistry-informed advice for cooking pasta, including how to prevent clumping noodles

On a molecular level, pasta dough consists of protein structures that hold starch molecules, and the starches absorb water during cooking, forming a gel that softens the pasta. Pasta should not be rinsed after cooking. Instead, some of the pasta water should be added to the pasta sauce, as the gelatinous starch will help the sauce stick to the pasta.

Low-and-slow smoking transforms tough cuts into tender, flavorful cuisine

Cooking meats at low temperatures over many hours breaks down muscle proteins and collagen into gelatin, making the meat juicy and soft. Patience, gentle smoke, and moisture retention are needed to avoid dry or chewy results.

How fermentation enables the pickling of food and the production of beer

This process occurs when microbes produce lactic acid, ethanol, or carbon dioxide after consuming sugars. The acid helps preserve vegetables in a brine solution during pickling and gives them a sour taste, while ethanol serves as the inebriant in alcoholic beverages. The acid and carbon dioxide give sourdough bread its taste and texture.

The chemistry of ancient tacos

This 16-minute podcast explores the chemistry of Mesoamerica's corn tortillas, which involve a 3,500-year-old chemical process called nixtamalization that releases vitamins, including niacin, one of the essential B vitamins. This process also makes the tortillas softer and more delicious. Corn tortillas were a staple in Mesoamerica, and the archaeologist interviewed in this podcast argues cultures like the Aztecs and Maya wouldn't have thrived without nixtamalization.

Learn the history of food science breakthroughs from the 20th century

Long after humans developed the means to produce sufficient food to feed civilizations, scientific research focused on a wide variety of objectives, such as developing methods to preserve food quality (accomplished via frozen food), speeding up cooking (leading to the microwave), and lowering the cost of sweetening food, which high fructose corn syrup provides.

How the methods of catching fish for food affects their taste

Commercially caught fish are often killed through suffocation, allowing the causing the fish extreme stress and flooding their bodies with stress hormones and lactic acid. These chemicals cause the fish's flesh to become bitter where it was once rich and quickens the rotting process.

How understanding a balanced diet can help you make good food choices

Eating a balanced diet—which includes a variety of foods from all food groups—is important for optimal health. It is also recommended to avoid ultra-processed foods, such as frozen meals, fast foods, soda, and flavored yogurt. The simplest way...

Roman concrete lasts longer than modern recipes—and even gets stronger

Today's concrete is made by binding ingredients, including chalk and silica sand, at high temperatures. Unfortunately, it weakens when exposed to salt water. This article explores how and why scientists are studying ancient Roman concrete, which grows stronger when exposed to salt water.

Watch an animation of what happens inside cookies as they bake in an oven

As temperatures rise and butter melts, trapped water expands, spreading the dough, which remains held together by a network of proteins. Maillard reactions produce browning on the surface beyond 310 degrees Fahrenheit (154 degrees Celsius), while caramelization can be triggered by baking past 356 degrees Fahrenheit (180 degrees Celsius).

High freezing speed restricts the development of gritty crystal chunks in ice cream

For this reason, ice cream does not maintain its smoothness when refrozen in a traditional freezer over several hours. The smooth texture is also made possible by balancing fat, sugar, and emulsifiers.

Why beefsteak tomatoes are named after a meaty dish

No, they won't get vegetarians into trouble, but beefsteak tomatoes did earn their name because of their meaty texture. People also associate the hearty beefsteak with sandwiches and burgers because they make for a perfect topping on meat-centric dishes. This quick explainer breaks down the basic etymology of the beefsteak and provides a few helpful ideas for using the tomato in your next meal.

Bath bombs can produce endothermic reactions that cool water

In bath bombs containing citric acid and sodium bicarbonate, water facilitates the reaction between the bicarbonate and acid, providing energy as the salt dissolves. The loss of energy in the water reduces the average speed of the water molecules, reducing the temperature of the bath.

Researchers have attempted to create more drought-resistant crops by introducing proteins that help protect tardigrades in their dehydrated tun state. The proteins’ ability to stabilize molecular degradation may allow scientists to develop refrigeration-free storage for vaccines, insulin, and blood.

Consistency and emotional engagement can improve the formation of memories

While sleep lets the brain re-trigger neurons associated with our experiences to cement them in long-term memory, repeating actions, like storing one's keys in the same location, can mimic these benefits. Emotionally charged memories are often ruminated upon, improving their future recall.

'This is my invariable advice to people: Learn how to cook—try new recipes, learn from your mistakes, be fearless and above all have fun.'

- Chef Julia Child (1912-2004)
