Abstract
Description
Production process of gelatin from alternatif material is needed to overcome the supply of halal gelatin. There are several obstacles to the use of gelatin, one of this related to religious aspects, that is prohibition of consuming ingredients from pigs. Explorations of production process of gelatin from waste of chicken slaughtering house need some modiifications, so can meet to the Indonesian Standard Regulation (SNI). The purpose of this research was to know the physicochemical properties of gelatin produced from chicken feet, and their characteristics from modification process of gelatin. The results showed that chicken feet has a high enough protein content, so it was potential to be used as a raw material for gelatin production. The best treatment was 2 days exraction using CH3COOH 1% solvent, followed by heating using waterbath for 1 hour. Yield of gelatin 6.75 ± 1.89%; water content 10,41 ± 0,63%; ash content 3,90 ± 0,43%; fat content 9.68 ± 1.21%; protein content 77,21 ± 0,58%; pH 5.62 ± 0.13; solubility was soluble; viscosity 6.67 ± 1.53 cPs; gel strength 164.75 ± 3.40 bloom; Cu residue content of 4.52 ± 0.71 ppm; Zn 9,92 ± 0,22 ppm; As 0,000 ± 0.00 ppm; Sulfite 5.56 ± 0.30 ppm. However, it is need improvement to reduce the fat content in gelatin product
