Abstract

There are disclosed methods for producing derivatives of lactide, including lactamides, propylene glycol, esters, acid anhydrides, modified starches, acrylic acid and pyruvic acid. Also disclosed are methods for producing lactide. Use of the lactide resulting from the methods in preparing foods and in the production of polymers and copolymers, is also disclosed.
