Grazing The Net: Milk replacer

Does drinking a glass of milk make you feel guilty? (We don't either, btw.) A startup hopes their

claims of guilt-free will help spur demand

for their replica milk.

Bioengineers Perumal Gandhi and Ryan Pandya developed

animal-free dairy products

to woo environmentally-conscious consumers who want better alternatives to milk. The two claim their milk replacer tastes and can be used like real milk, with the same (if not improved) nutrient profile. Their milk will be sold under the brand name "Perfect Day."

In support of dairies, however, is new research by USDA that is

developing an environmentally friendly film

made of the milk protein casein. These casein-based films are up to 500 times better than plastics at keeping oxygen away from food and, because they are derived from milk, are biodegradable, sustainable and edible.
