Abstract:

Tussah fibroin peptides were prepared from tussah silk fibroin by hydrolysis method with phosphoric acid. On the basis of single-factor test, the preparation process was optimized using the response surface methodology. The effects of various factors on the recovery of tussah fibroin peptides were investigated, and the performance of samples obtained under the optimized conditions was analyzed. The results show that the optimal hydrolysis conditions are as follows: the mass fraction of liquid material is 9.93%; the hydrolysis temperature is 91.11 ℃; the hydrolysis time is 5.44 h; the theoretical recovery rate is 70.34%. The actual recovery rate can reach 69% which is consistent with the theoretical level. The optimized hydrolysis technology for preparation of tussah fibroin peptides was established using response surface methodology. The performance experiments of tussah fibroin peptides show that the sample has good hygroscopic and moisturizing efficacy, and functions of sunscreen and bacteriostasis. Tussah silk peptides have high application value in the development of natural skin care products.

Key words: tussah, fibroin peptide, hydrolysis process, response surface method
