Effect of soy protein isolate and starch mixture coating on qualities of chilled beef

Effect of the starch(cassava starch,sweet potato starch,potato starch,corn starch,pea starch,and amylose)and soy protein isolate mixture coating on quality of chilled beef was evaluated.Specifically,changes of weight loss,color,pH value,TBA value and sensory evaluation score of the chilled beef were investigated during the storage at 4℃ for 5days.Finally,the pea starch and corn starch with the soy protein isolate mixture coating not only reduced the weight loss(9.97% and 12.83%,respectively,lower than that of PVC package),but also held the sensory index of the stored chilled beef.
