CAMBRIDGE, MASS. — A team of researchers at the Massachusetts Institute of Technology in Cambridge has created a coating that may be used to line the inside of bottles and keep product, such as ketchup, from sticking to the inside of the bottles. The coating, called LiquiGlide, is made from edible food materials approved by the Food and Drug Administration.

The flavorless coating will not mix or leach into the contents of the bottle. The researchers have tested the coating on glass, plastic, metal and ceramic so far. LiquiGlide placed second in this year’s MIT $100K Business Plan Contest. Videos showing how LiquiGlide allows product to come out of containers may be seen at
