摘要: ABSTRACT: Edible films were produced using whey protein isolate (WPI) (5%, w/v), glycerol (3.3%, w/v) and candelilla wax (0.8%, w/v). One set of was heat cured at 90°C for 12 h another 80°C 24 h. WPI-based films, together with collagen put through a meat-processing scheme typical Polish sausage manufacture. Meat-processing conditions stage 1: 57°C/60 min/36% RH; 2: 65°C/90 min/60% 3: 77°C/30 min/80% RH. Effects on mechanical properties: tensile strength (TS), elongation (%E), apparent modulus (AM) determined. All remained intact throughout the process. TS, %E, AM did not change during multistage cooking The %E heat-cured WPI similar to that also stages. TS both initially lower than continued decline end (P < 0.05) go
