Watch the iterative process of successfully printing a slice of vegan cheesecake

Vegan cheesemaking relies heavily on nuts and seeds

We might associate vegan cheese with current health trends, but there’s actually been a small-but-growing market for plant-based cheeses since the 19th century. But for vegan cheeses to appeal to a wider demographic, they have to compete with the familiar flavors and textures of dairy cheeses.

NASA funded research into creating pizza with a 3D printer

The agency awarded a contract for the development of devices that can create edible structures from long-lasting dry powders when mixed with liquids or pastes. By delaying this integration until the time of consumption, food could last longer than the current six-month expiration of freeze-dried meals for Mars expeditions.

Tasty vegan ice cream depends on fat

Making delicious ice cream without dairy is a challenge for food scientists because most nondairy milks have more water than fat, which creates tasteless ice crystals when frozen. The key is finding a base with enough fat to give the finished product its signature creamy mouthfeel.

Microgravity environments improve the success of 3D bioprinting

Gravity can cause gaps, such as those in the chambers of a 3D-printed heart, to collapse before stem cells, hydrogels, and biochemicals bind together during the bioprinting process. Rather than Earth's surface, some bioprinting is done on the International Space Station, where defective organs are also printed to test treatment methods.

Multi-material 3D printing produces filament waste if only one nozzle is used

When swapping between colors or materials in a fused deposition modeling system, a considerable amount of filament is purged from the nozzle before introducing a new filament. Filament extruders can create new filament from purged elements, but the device combines colors and produces filaments of inconsistent diameter.

Watch the engineering challenges overcome in turning a 3D printer into a tattoo machine

The DIY project required reprogramming the printer to operate on a curved, 2D surface rather than making flat layers in 3D, editing replacement firmware to bypass temperature safety checks, and developing a rapid system to stop the tattoo in case of an emergency. The final product printed "LEG" on a volunteer's leg.

The benefits of 3D printing batteries, from safety to sustainability

Rather than using the liquid electrolyte commonly found in lithium-ion batteries, 3D-printed batteries would use a solid layer, which can be custom-built into different shapes, deliver higher energy density by building thinner layers, and be fabricated with fewer raw materials compared to injection molding.

There are 6 essential steps in cheesemaking

The six basic steps that are required to turn milk into cheese start with acidification and end with ripening (aka aging). This guide explains what happens at each step and how it contributes to the finished product.

Massive 3D printers have been used to build homes by stacking layers of 'concrete toothpaste,' a fire-resistant material that effectively insulates against outside noise.

TikTok is obsessed with weird cottage cheese recipes

Cottage cheese “cookie dough.” Pizza cottage cheese bowl. Cottage cheese queso dip. TikTok influencers are suddenly posting nonstop cottage cheese recipes. It might be echoes of the 1990s weight-loss obsession, when diet culture encouraged the consumption of questionably tasty low-fat foods and not much else. Now, cottage cheese’s high protein content has made it an intriguing prospect for online fitness gurus who say that it’s the key to building muscle.

Explore a list of 12 recipes incorporating techniques from molecular gastronomy

The recipes include popcorn shooters that taste like liquid caramel corn, almost-instant soft serve made by blending frozen fruit with sugar and fromage blanc, a fusion of fried rice and pizza, and skewered fruit coated in a broiled, glossy meringue.

What makes food crispy, and how science can be used to maximize this property

The fracturing texture experienced when biting into vegetable tempura, fried chicken, pastry crusts, and other foods comes from having a dehydrated, porous surface. When frying food in hot oil, trapped water vaporizes and escapes, creating tunnels and pores in the food as it dehydrates. Breading, particularly with the large, irregular shapes of panko, and leaveners can help create more air spaces.

Stereolithography uses light to fabricate objects in layers via chemical reactions

Specific locations in a tank of light-sensitive liquid resin are exposed to projected light, causing them to cure onto a build platform. The resulting cross-section of hardened plastic is moved slightly away from the light source, exposing it to resin once more, and the process repeats to produce successive layers.

An interactive periodic table maps every possible combination of cheese variables

Plotting milk type, texture, rind, mold, aging, and processing as intersecting axes, the tool shows which combinations already exist as named cheeses, which survive only as rare regional styles, and which remain entirely unexplored.

Objects can be 3D printed with light by projecting 2D computerized tomography (CT) scans onto rotating cylinders of resin, which solidify upon exposure.

It took 70 years for computer scientists to determine how to cut a cake fairly

The cake-cutting problem explores how to divide something fairly, which is not solely about cutting evenly-sized pieces. A protocol that accounted for personal preferences (e.g., a corner piece) between just three people took 16 years to develop.

Explore a library of data files for 3D printing

Data files are organized by category, including gadgets, learning, and fashion, with most available in .stl format, which is native to computer-aided design software, and presliced. Some files are also available in .3mf, an open-source file format developed as a universal standard for high-fidelity 3D printing.

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

Keeping eggs at room temperature produces smoother batters when baking, and doing the same with tomatoes helps prevent a mealy, granular mouthfeel. Salting meat a day before gives more time for proteins to break down, improving flavor and tenderness, while cooking vegetables in well-salted water can lock in nutrients and color.

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).

What's inside an Oreo?

If you look at the ingredient list on your Oreo packaging, you may discover that you don't recognize—or can't even pronounce—some of the listed ingredients, let alone know what they're used for! For instance: Did you know that soy lecithin helps makes oil and water mix? Or that cocoa processed with alkali becomes darker and less acidic? A food scientist breaks down what's inside an Oreo in this seven-minute video.

Why processed foods can be so addictive

In recent years, many critics have voiced their concerns about the food industry and how ultra-processed foods affect our health. Despite our awareness of these issues, processed foods are still incredibly hard to remove from our diet. In this podcast by The Guardian, Dr. Chris van Tulleken explains how “junk food” is created to get us hooked, how it negatively affects us, and what we can do to improve our eating habits.

Explore the water footprint of producing various proteins, fruits, and vegetables

This interactive gallery highlights the various types of water behind the production of biofuels, foods, and materials such as cotton. Diets high in bovine meat, whose production requires 15,415 liters of water per kilogram (1,847 gallons per pound), are among the most water-intensive, whereas every kilogram of vegetables uses 322 liters of water (39 gal/lb) to produce.

When experiencing turbulence, fluid elements undergo stretching and folding

Simulations show patches of fluid particles, such as splashes of milk, bend under turbulent flow, creating curvature that grows linearly then exponentially. This accelerated deformation enhances folding and mixing faster than other methods, such as stirring or beating.
