Abstract
A modified vegetable protein binder produced by and a method of producing a modified vegetable protein binder for paper coatings by bleaching a vegetable protein extract with an oxidizing agent and a magnesium compound to provide a bleached vegetable protein material and then modifying the bleached vegetable protein. The modification is generally hydrolyzing the bleached vegetable protein and when desired, also carboxylating the bleached vegetable protein.
