The Functional Properties of Buffalo skin Gelatin Extracted Using Crude Acid Protease from Cow’s Abomasum

The study was investigated the functional properties of buffalo skin gelatine. Gelatine was extracted from swamp buffalo skin using crude acid protease from cow’s abomasum (CAPC) in concentration variation 0; 2.5; 5; and 7.5 U/mg. The temperature to hydrolysis included at 28 °C, 37°C and 40°C. The emulsion activity index (EAI), Emulsion stability index (ESI), foaming expansion (FE) and foaming stability (FS) were investigated. The interaction between CAPC concentration and hydrolysis temperature has a significant effect (P
