Abstract:

In this study, lactic acid-pressurization extraction technology was used to extract chicken bone nutritional components, and the extraction conditions were optimized using response surface methodology. The results showed that the optimal conditions are as follows: extraction pressure 0.11 MPa, extraction time 62 min, material to liquid ratio 5.6:1 (W/W) and lactic acid amount 12%. Under these conditions, the comprehensive index on contents of hydroxyproline, calcium and phosphorous and degree of protein hydrolysis is calculated to be 33.604.

Key words: chicken bone nutritional component, lactic acid-pressurization extraction, response surface methodology
