Milk from lab – level 3

18-03-2022 15:00

In the US, 10% – 15% of milk is made from nuts or soy; however, laboratory-produced dairy products are now becoming popular.

Dairy alternatives have a long history, and scientists have created a non-plant based milk. It uses a combination of some new and old technologies, in which genetically engineered microbes create milk proteins. Then, scientists put the proteins into large fermentation bioreactors to create animal milk protein. The result is similar to real animal milk protein; however, the process involves no animals.

This alternative to real dairy has environmental benefits than traditional dairy or some of the existing alternatives, as well as its match on the taste and texture of real milk. Unlike traditional dairy, it requires no cows; they create gas and pollute water. Also, it avoids ethical concerns about animals treatment in industrial farms.

Difficult words: genetically engineered microbes (bacteria that scientists created or changed), protein (the structure if a set of cells), fermentation bioreactor (a device that makes a chemical process to change a food or drink).
