KARAKTERISTIK GELATIN KULIT KAMBING YANG DIPRODUKSI MELALUI PROSES ASAM DAN BASA Characteristics of Goat Skin Gelatin That Produced Through Acid and Alkali Process

Needs of gelatin in Indonesia has increased along with the development of industries. On the other hand, the gelatin is still imported from other countries. Goat skin is rich in protein, especially collagen. This collagen can be processed into gelatin. The aim of this study was to determine the characteristic of gelatin made from goat skin. The production of gelatin was done by two types of curing material: acid (i.e. CH3 COOH) and alkali (i.e.Ca(OH)2 ). The experimental design applied in this study was CRD factorial 2x3 with 3 replications. While the treatment applied in the study were curing period (2 and 4 days) and concentration of material for curing (3,6 and 9 percent). Commercial gelatin was used as control. The result showed that gelatin produced by either acid or alkali treatment had similar characteristic to the commercial gelatin. The best characteristic of gelatin, either quantitative and qualitative one, was produced from 4 days curing period with 9 percent of Ca(OH)2. Keywords: Gelatin, Goat Skin, Curing Acid, Alkali
