Effect of ultrasound pre-treatment on the characterization and properties of collagen extracted from soft-shelled turtle (Pelodiscus sinensis)

The aim of the present study was to evaluate the effect of ultrasound pre-treatment on the characterization and in-vitro digestion properties of collagen from turtle calipash and the antioxidant activity of its hydrolysates. The results showed that ultrasound significantly increased the collagen yie...

Description
Summary:The aim of the present study was to evaluate the effect of ultrasound pre-treatment on the characterization and in-vitro digestion properties of collagen from turtle calipash and the antioxidant activity of its hydrolysates. The results showed that ultrasound significantly increased the collagen yield compared with that from conventional extraction (ASC, P
