Development of industrial ultrasound system for mass production of collagen and biochemical characteristics of extracted collagen

Collagen is a widely used material in food and cosmetic products, but it has high price because of complicated extraction process and low yields. In order to overcome these problems, a mass production system of collagen from fish skin has developed using an industrial scale of ultrasound extraction equipment. Collagen was extracted from flatfish skin using 0.05 M acetic acid solution for a total of 3 h in an ultrasound system and was collected...
