Physical Quality and Microstructure of Casein-Sodium Tripholyphosphate Edible Film Making

Abstract

Edible film is a natural packaging that is environmentally friendly (biodegradable) which is strong and elastic, resembling plastic packaging. Cow's milk has component fractionation capabilities that produce a variety of functional ingredients for applications in the food industry. Cow's milk has properties, among others, as an antibacterial agent. Sodium tripholyphosphate (STTP) is one of the additives to improve the integrity of edible films. The purpose of this study was to observe the effect of using different casein on the characteristics of the edible film (film thickness, transparency, water content, solubility in water, and swelling). Edible films were made from different formulations of chitosan, casein, and Sodium Tripholyphosphate (STPP) (
