Karakterisasi Gelatin Hasil Ekstraksi dari Tulang Sapi Melalui Proses Perlakuan Basa NaOH

Gelatin is a soluble protein that acts as gelling agent and commonly used an ingredient in both food non-food production. Since bone composed of collagen fibers, it can be raw material for gelatin Beef waste product rarely used. Sodium hydroxide (NaOH) processing the production type B because remove fats oils. The purpose this study was to investigate effects 2%, 3%, 4%, 5%, 6%NaOH concentrations on properties bovine at 4 6 hours extraction time. observed were yield, water content, ash pH, viscosity, microbial contamination. results showed pretreatment condition with 6% NaOH affected highest content dan contamination have fulfilled SNI. conclusion gelatin, there are some advances producing excellent applications.
