Abstract

THE EFFECT OF ACETIC ACID CONCENTRATION ON CHARACTERISTICS OF CHICKEN LEG SKIN GELATIN. This research was aimed to determine the effect of differenceacetic acid (CH3COOH) concentration on chicken legs skin gelatin. The experiment were determined by analysis of Completely Randomized Design with one factors and five replicates of treatments.The factor was concentration of acetic acid solution consisting 4 level (1, 3, 5 and 7%).The results showed that the difference  concentration acetic acid solution had high significant effect (P<0.01) on the the  yields, viscosity, gel strength and pH value ofchicken legs skin gelatin.Yield of chicken legskin gelatin was13.57 to 15.49%, viscocity was ranged between  4.30 to 5.76,  gel strength was 61.15 to 68.29 g Bloom and pH value was 5.24 to 5.58. The conclusion of this research was the chicken leg skin gelatin using acetic acid solution concentration 1 % to 7 % had the similar characteristics with the commercial gelatin and includedyields, viscosity, gel strength and pH value of Indonesian National Standard gelatin.   Key words : Acetic acid,  Gelatin and  Chicken legs skin

Abstract

THE EFFECT OF GUAVA LEAF SOLUTION CONCENTRATION AND SOAKING DURATION ON THE QUALITY OF CHICKEN EGGS.      This study aims to determine the effect of guava leaf solution concentration and soaking time on the quality of chicken eggs. This research was conducted from November to December 2018, at the Laboratory of Animal Product Technology, Faculty of Animal Husbandry, Sam Ratulangi University, Manado. The method used is Completely Randomized Design (CRD) with a factorial pattern consisting of 2 factors. Factor A was the concentration of solution of guava leaves and factor B is the length of immersion with 4 replications. The treatments used are: Factor A concentration of solution of guava leaves A1 = 3%, A2 = 6%, A3 = 9%, A4 = 12%. Factor B was duration of immersion B1 = 6 hours, B2 = 12 hours, B3 = 18 hours, B4 = 24 hours. The variables analyzed were a decrease in egg weight, egg white index and egg yolk index. Data obtained were analyzed by variety. If there are significant differences between treatments, it will be continued with Duncan Test. The results of the variance analysis showed that the interaction had a significant effect (P <0.05) on the decrease in egg weight and did not significantly influence (P> 0.05) on the egg white index and egg yolk index. Duncan's Test results for decreasing egg weight showed the concentration of guava leaf solution 3% and soaking time 6 hours  gave good results for the quality of chicken eggs. It was concluded that the concentration of 3% and the soaking time of 6 hours gives good results on decreasing egg weight. As for the egg white index and egg yolk index showed good results with concentration of 12% and 24-hour immersion time. Keywords: Guava leaf, Egg weight, Egg white index, Egg yolk index.
