Study on Extraction Technology and Functional Activity of Collagen from Swim Bladder
With the increase of peoples demand for health and attention to natural food ingredients,the application prospect of swim bladder collagen in the field of condiments is gradually expanding.Some food manufacturers and innovative companies have begun to try the application of swim bladder collagen in condiments.Products added with swim bladder collagen can be seen in some condiments of high-end restaurants or food brands,so as to enhance the flavor of food.However,the current extraction technology of collagen from swim bladder is still in its early stage,and a series of methods are needed to destroy the multi-level structure of protein.In order to better develop and utilize collagen from swim bladder,in this study,single factor test and orthogonal test are used to study and optimize the extraction technology of collagen from swim bladder.The research results show that the optimal processing technology for extracting collagen from swim bladder is acetic acid concentration of 0.4%,extraction time of 20 h and solid-liquid ratio of 1:55.
