Abstract

ABSTRACT Pretreatment of chemical acids using organic chemicals has been widely applied, while pretreatment using microbial Lactobacillus plantarum to form ossein in goat skin has not been done much. Application of Lactic Acid Bacteria (LAB) microbial species L. plantarum is thought to affect health and environment friendly. This study aims to determine the characteristics of goat skin gelatin at different ages of L. plantarum 1uhcc pretreatment and acetic acid (CH3COOH). Each treatment was repeated 3 times. The study design used a Split Plot Design with acid source treatment as the main plot and the age of goats 1, 2 and 3 years as subplots. The results showed a very significant effect (P<0.01) between the age of the goat with gel strength, pH, viscosity and color. The highest gel strength and viscosity at 1 year of age with L.plantarum pretreatment respectively (441.37±0.78 g bloom) and (9.22±0.09 cP). Goat skin gelatin has the highest pH at 1 year of age with L.plantarum 5.24±0.16. Similarly, the effect of gelatin (P<0.05) with a brightness level (L) 76.38±1.10 and redness (a) 11.13±1.58 affect the age of goats and acidic sources while yellowish (b) 33.81±2.34 only affects the acid source. Age of goats with different acid pretreatment has an impact on the physicochemical properties of goat skin gelatin. Goat age 1 year with L.plantarum pretreatment showed optimal results.

Abstract

This study aimed to determine the effect of cooking and level of vegetable addition and their interaction on the organoleptic quality of chicken nuggets. The research design consisted of 2 factors: the first factor was vegetable cooking treatment (fresh and steamed), and the second factor was vegetable addition level (0%, 5%, 10%, and 15%). The parameters measured were the organoleptic quality of chicken nuggets (color, texture, aroma, taste, t and acceptance/hedonic). The results showed that cooking treatment had no effect (P>0.05) on the organoleptic quality of nuggets, but the level of vegetable addition affected (P<0.05) the organoleptic quality of nuggets. Increasing the level of vegetable addition decreased the color value of L*, a*, but increased the color of b*. Besides, the organoleptic test decreased the attribute scores of color, aroma, taste, and texture but was still accepted by panelists up to 15% vegetable addition level. There was no interaction between cooking treatment and the level of vegetable addition on the organoleptic quality of nuggets. From this study, it can be concluded that the best treatment is using fresh vegetables up to 15% addition level. Keyword: Chicken Meat, Broccoli, Carrot, Chicken Nuggets, Organoleptic
