Abstract
The present invention describes tunable methods of treating cellulosic materials with a barrier coating comprising a prolamine and at least one polyol fatty acid ester that provides increased oil and/or grease resistance to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for adhering of the barrier coating on articles including articles comprising cellulosic materials and articles made by such methods. The materials thus treated display higher lipophobicity and may be used in any application where such features are desired.
Claims20
A barrier coating comprising a prolamine and at least one polyol fatty acid ester (PFAE), wherein said polyol comprises a cyclic structure and 1 to 2 fatty acid moieties or 3 to 5 fatty acid moieties, and a fatty acid is saturated.
A method for tuneably derivatizing a cellulose-based material for lipophobic resistance comprising contacting the cellulose-based material with a barrier coating comprising a prolamine and at least one polyol fatty acid ester (PFAE) and exposing the contacted cellulose-based material to heat, radiation, a catalyst or combination thereof for a sufficient time to adhere the barrier coating to the cellulose based material.
A barrier coating consisting essentially of a prolamine and at least one polyol fatty acid ester (PFAE), wherein said polyol comprises a cyclic structure and 1 to 2 fatty acid moieties or 3 to 5 fatty acid moieties.
