Preparation and Properties of Whey Protein Packaging Film
A protein packaging film was successfully prepared using whey protein concentrate (WPC) as rawmaterial. Protein concentration, plasticizers concentration and temperature were discussed. Research resultsshow that the increasing of protein concentration lead to decreasing barrier properties of WPC film butimproving its mechanical properties. Though barrier properties of WPC film lost to some extent owing toaddition of glycerol, its extensibility was greatly improved. When heating temperature is 80℃, the barrierproperties and tensile strength of WPC film come to the best. Response surface analyses indicate that WPCfilm shows the optimal packaging performance when concentration of WPC is 10.2%, heating temperature is82℃ and concentration of glycerol is 2.7%.
