ABSTRACT

This study aims to determine how to extract the gelatin from catfish bones by using pineapple peel waste as a soaking material in the pre-treatment stage and identification the chemical properties qualitatively of the gelatin produced. Kampung Patin in Kampar Regency, Riau Province, is one of the catfish cultivations in Indonesia. It is a center for producing catfish that produces fish bone waste. In this study, gelatin extraction will be undertaken in several stages: the preparation of pineapple waste liquid extract and gelatin extraction (pre-treatment and main extraction stages). Catfish bones will be soaked in 1:5 (m/v) pineapple waste liquid at the pre-treatment stage for 6, 12 and 24 hours. While in the central extraction, ossein will be immersed in water at a temperature of 750C for 5 hours. The gelatin chemical testing qualitatively results for bond peptide of the three treatments of immersion time formed a puprple color ; for Triptophan content of the three treatment of immersion time showed that does not contained the amino acid of tryptophan; and for Sulfur test that showed were does not formed of black to brown precipitate. This showed that catfish bone gelatin that can be seen from the amino acid composition formed.
