KUALITAS FISIK GELATIN HASIL EKSTRAKSI KULIT SAPI DENGAN LAMA PERENDAMAN DAN KONSENTRASI ASAM KLORIDA (HCl) YANG BERBED
Abstract: Gelatin is a
compound hydrolysis of collagen fibers. The purpose of this research was to
determine the influence of concentration of hydrochloric acid (HCl). and
soaking time on the bovine hide making toward physical quality gelatin. The
materials were bovine hide, hydrochloric acid and distilled water. Data were statistically analyzed
by A Completely Random Design with factorial pattern consist two factors;
hydrochloric acid concentration (3% and 5%) and soaking time (4, 8, 12 and 16
hours) with three times replications. Parameters measured were pH, gel
strength, yield and viscosity. The result showed that pH, bloom strogh, yield and viscosity, centipoise
(cP) of gelatin was 2.70-4.12, 53,33-185,00 g, 18.04-37.93% and 1.49-1,79,
respectively. An interaction between hydrochloric acid and soaking time
significantly (P˂0.01) influence in following categories: T pH, gel strength,
viscosity and yield. It is conclude that the best combination treatments
is HCl 3% and 12 hours of soaking
soaking.
