海地瓜中具吸湿保湿特性的胶原蛋白肽提取工艺研究
Study on extracting collagen peptides with characters of moisture retention and absorption capacity from Acaudina molpadioides
摘要
Abstract
The extraction technology of collagen peptides from acaudina molpadioides was studied in this article. The non - collagen protein of acaudina molpadioides was separated by sodium chloride solution, using single factor experiment to validate the optimal conditions of sodium chloride solution including the concentra- tion of 9%, 10 times volume of the quality of acaudina molpadioides, marinated for 24h. Under these terms, the proportion of separated non - collagen protein in the total protein accounted for 11. 5%. Based on single enzyme factor experiment, AS. 1398 neutral protease was selected to hydrolyze collagen protein of acaudina molpadioides. Considering the moisture -absorption and moisture -retention, orthogonal experiment was conducted to optimize the preparation of the collagen peptides from acaudina molpadioides, with the results of the solid/liquid ratio 1： 2, temperature 40℃, amount of added enzyme 2400 U/g, pH 7. 5, and reacting time 3h, the moisture absorbency and moisture -retention ability achieved to 6. 11% and 81. 23%, respectively.关键词
