Karakteristik Gelatin Dari Tulang Ikan Nila (Oreochromis Niloticus) Yang Direndam Menggunakan Ekstrak Cair Buah Nanas (Ananas Comosus L. Merr)

ABSTRACT
This study aims to find out the chemical and physical characteristics of
gelatin from tilapia bone soaked using pineapple liquid extract. Pineapple fruit is
known to contain citric acid that is quite high. The research method used in this
study is an experimental method by pre-treatment (soaking) of fish bones in liquid
extracts of pineapples using different times. G20 (soaking of fish bones in
pineapple liquid extract for 20 hours), G30 (soaking of fish bones in pineapple
liquid extract for 30 hours) and G40 (soaking of fish bones in pineapple liquid
extract for 40 hours). The analysis parameters in this study are SDS-PAGE values,
sensory analysis, viscosity, pH values, moisture and ash content. The results of
this study showed that gelatin extract of tilapia bone with soaking
(demineralization process) using liquid extract with pineapple fruit at different
times, produces SDS-PAGE value (molecular weight of gelatin protein 80 kDa, 60
kDa, and 50 kDa), sensory characteristics that meet the standards (yellowishwhite
powder form, smells of weak fish and tasteless), viscosity (1.39-1.52 cP),
The physical properties of pH (5.06-5.26), chemical properties namely moisture
content (4.54-6.47%), ash content (7.65-10.25%. The best treatment was obtained
in the pre-treatment (soaking) of tilapia fish bones within 40 hours with liquid
extract of pineapple fruit.
