Abstract
An edible, water-resistant composition that can be formed into shaped articles including film comprises a water-resistant solid composition of casein. The casein composition may be directly precipitated from a solution under high pressure treatment with carbon dioxide. The composition does not have to be crosslinked, but takes advantage of the natural water-insolubility of the protein backbone of the casein. The casein composition may be combined with edible or inert flexibilizers to improve film properties, and the film may be used to protect food products or food compositions, yet provide moisture protection. The film of casein material may exhibit water-insolubility in deionized water at 20.degree. C. of less than 25% by weight after two hours of immersion of the film in the deionized water, with or without mild agitation.
