Abstract

To obtain the high-quality proteins from insect resources,proteins extraction from pupae of Dendrolimus punctatus Walker using alkali proteinase was studied.The nutrition evaluation was also carried out.The results revealed that time and temperature of crystallization had obvious influence on the concentration of polyunsaturated fatty acids.The best condition was as the follows:crystallization temperature was-8℃,crystallization time was 18h,the iodine value and peroxidation value under this condition were 2.30 g(I2)/g,61.75%,respectively.

Key words： insect resources; Dendrolimus punctatus Walker; larva; polyunsaturated fatty acids; low temperature crystallization
