Effect of Beeswax, Palmitic Acid and Stearic Acid on Soybean Protein-Isolation/Carboxymethyl Cellulose Composite Films

Abstract:

The effects of beeswax, palmitic acid and stearic acid on properties of soybean protein-isolate/carboxymethyl cellulose composite films were compared. The palmitic acid leaded to a higher tensile strength, water vapor barrier and oxygen barrier of composite films than the beeswax and stearic acid. However, the palmitic acid lowered the elongation at break and leaded to a slight yellow. Hence, the palmitic acid was a better option to improve the tensile strength and water vapor barrier of soybean protein-isolate/carboxymethyl cellulose composite films.
