Effects of freezing-thawing pretreatment combined with liquid nitrogen and dilute acid on the gelatinization of collagen

The method of liquid nitrogen quick-freezing combined with dilute acid rapid-thawing was applied as a pretreatment to extract gelatins from pigskins, and the influence of HCl concentration (0–2% (v/v)) on the gelatinization of collagen in pigskins was observed. The freezing-thawing using liquid nitr...
