Dairy proteins can be made with genetically modified yeast
We know a lot more about how the company’s Impossible Burgers are made. DNA from soybean plants is inserted into genetically modified yeast fermented, so it creates a lot of heme – the molecule that gives meat its flavor. Other companies working on what might be called “impossible cheese” use yeast or other microbes to produce casein and whey protein, similar to the Impossible Burger method. Casein is the protein that makes mozzarella cheese stretchy. New Culture, a company that makes mozzarella with no help from cows, says their product performs well in taste tests.
As Impossible Foods CEO Pat Brown told the MIT Technology Review, the company wants to replace as many cow products as possible, with the explicit goal of making animal agriculture obsolete. “Our mission is to completely replace the world’s most destructive technology by far, which is the use of animals, by 2035,” he said. The livestock industry is to blame for 14.5 percent of the world’s greenhouse-gas emissions, and 61 percent of that comes from beef or dairy cows. Greenhouse gases from human industries cause climate change. In addition to milk, Impossible Foods is working on a steak marbled with stuff that melts and tastes like fat. The company is working on chicken and fish substitutes, too.
Impossible Foods is not impressed with traditional non-dairy milk
Impossible Foods’ CEO doesn’t think that non-dairy alternatives to cow’s milk will cut it. He can’t stand the taste of soy milk. Oat milk, praised for its flavor and nutrition profile, just passed soy as the No. 2 non-dairy milk option on the market. Oat milk also scores much better in sustainability tests than the No. 1 non-dairy alternative, almond milk. On the other hand, baristas give oat milk mixed reviews for taste and mouthfeel. And despite the environmental benefits of oat milk, Impossible Foods CEO Brown remains unimpressed with the whole non-dairy sector. Brown said that if any of those milk alternatives were truly good, people would have stopped buying real milk by now.
