The Characterization of Physicochemical, Nutritional, and Flavor Properties of Bovine Hide Gelatin Prepared from Different Raw Materials

Gelatin from bovine hide, especially yak hide, is valued in the food and pharmaceutical in- dustries; however, as the most common domestic cattle in China, gelatin made from yellow cattle hide remains unexplored. Thus, the physicochemical properties, nutritional compo- nents, and flavor characteristics of gelatin produced from yellow cattle hides and yak hides, both before and after hair removal, were analyzed. It was found that yellow cattle hide gelatin (YCHG) not only had a higher protein...
