Scientists have altered the genes of a dairy cow to produce milk that’s rich in a protein used in numerous food products and lacking in a component that causes allergies in humans.
Using a process called RNA-interference that turns certain genes on or off, scientists from New Zealand produced a cow whose milk had increased casein, a protein used to make cheese and other foods, and almost no beta-lactoglobulin, a component in milk whey protein that causes allergies, Bloomberg reports.
