PENGARUH PERBEDAAN KONSENTRASI LARUTAN ASAM ASETAT TERHADAP NILAI KEKUATAN GEL, VISKOSITAS, KADAR PROTEIN, DAN RENDEMEN GELATIN KULIT SAPI
Abstract
THE EFFECT OF DIFFERENT CONCENTRATION OF ACETIC ACID SOLUTION ON THE GEL STRENGTH, VISCOSITY, PROTEIN CONTENT AND RENDEMEN VALUE
This research conducted to determine the effect of different concentration of acetic acid solution on the gel strength, viscocity, protein content and rendemen of cow skin gelatin. The material used cowskin and acetic acid solution. This study used Completely Randomized Design (CRD). The treatments were concentration of acetic acid solution (1%, 3%, 5% and 7%) and four replicates of treatment. The result showed that the different concetration of acetic acid solution had no significant effect (P>0.05) to the gel strength and rendemen value of gelatin, but it had significant effect (P<0.05) on viscosity and protein content of cow skin gelatin. It was concluded that acetic acid solution 3% had the best gel strength, viscosity, protein content and rendemen value of cow skin gelatin.
