PENGARUH KONSENTRASI LARUTAN ASAM ASETAT DAN LAMA PERENDAMAN TERHADAP SIFAT FISIK DAN KIMIA GELATIN KULIT BABI

The objective of the study was to examine the extent to which the effect of different concentrations of acetic acid and the duration of immersion in acetic acid (CH3COOH) solution to the physicochemical gelatin of pigskin. This research has been carried out from September to December of 2017 at Animal Product Technology Laboratory of Faculty of Animal Husbandry of Sam Ratulangi University of Manado and the analysis was done at Food Engineering Laboratory, Faculty of Agricultural Technology Universitas Gadjah Mada Yogyakarta. This study used a 3x3 factorial pattern design with concentration treatment and long immersion in acetic acid (CH3COOH) solution, each treatment was repeated three times (Steel and Torrie, 2001). The results showed that the pigskin gelatin produced from 3% acetic acid solution and immersion time 24 hours had the best physicochemical properties.

The aim of the study was to examine the effect of differences in the concentration of lime solution (Ca (OH) 2) on the physical and chemical properties of gelatin in cow skin. This research was conducted in December 2017 until January 2018 at the Laboratory of Animal Product Technology at the Faculty of Animal Husbandry, Sam Ratulangi University of Manado and analysis was carried out at the Food Engineering Laboratory, Faculty of Agricultural Technology, Gadjah Mada University, Yogyakarta. This study used a Completely Randomized Design (CRD) 4 x 4 with the treatment of the concentration of calcium hydroxide (Ca (OH) 2) solution, each treatment was repeated four times (Steel and Torrie, 2001). The results showed that the treatment of the concentration of calcium hydroxide (Ca (OH) 2) gave no significant difference (P> 0.05) on gel strength, viscosity, yield, pH and water content of gelatin in cow skin.*eprm*

Viscometric Study

Some ways of estimating the values of the intrinsic viscosity of chitosan were analyzed. It was shown that the method of Irzhak and Baranov for estimating the current value of the intrinsic viscosity allows to adequately estimates the conformational state of the macromolecular coil and its degree of swelling.
