The Impossible Burger- Look at that meaty red color!
One may not consider the scientific research required to replicate the satisfying texture of meat, but decades of studies have gone into fake meat production. Soy protein, which is globular, is commonly used in fake meat products, because once it has been denatured, it becomes more stringy and fibrous. Denaturation is the altering of protein structure, and is dependent on the temperature and pH on protein's environment. This information relates directly to the AP Biology curriculum, because the curriculum focused on how the structure of proteins relates to their function. The image below uses a fried egg as a great example of a denatured protein.

Another newer method is crosslinking proteins to get a more wet and juicy consistency. Companies such as Beyond Meat and The Impossible Burger are making fake meat more real, without all of the antibiotics, hormones, and additives. I actually tried the Impossible Burger at Momofuku in NYC, and I thought I was eating real meat. It surprised me, but it was amazing how accurately the taste and texture of meat could be replicated.

Many people know about fake meat packages that are now readily available at most grocery stores, but what about the products that aren't yet available to the public, and are still being tested? The newest experiment in the world of food science is fake meat growth using real animal stem cells. This process takes actual animal muscle tissue, and places the cells in an environment that encourages growth and cell replication. The product is a lab-created burger that is as close to the real thing as possible. The Washington Post says, "...a 2011 study calculated that growing meat in labs would cut down on the land required to produce steaks, sausages and bacon by 99 percent and reduce the associated need for water by 90 percent. What’s more, it found that a pound of lab-created meat would produce much less polluting greenhouse-gas emissions than is produced by cows and pigs, even poultry." With less environmental impacts, what's not to love? For one, the price tag. These products currently cost tens of thousands of dollars for one burger, so until these 'real' meats become cheaper to create, many still rely on their trusty soy burgers.
