Abstract
A method wherein grain flour proteins are cross-linked with aldehydes and bleached with a bleaching agent to form cross-linked transparent polymers is described. The process uses ethanol and water for the extraction at acid or basic pH's and optionally heating with or without a reducing agent to provide the polymers to be bleached and cross-linked. The polymers are particularly useful as films for packaging.
