Abstract

This aim of this research was to analyse the influence of Lactobacillus casei in edible coating on it’s antibacterial activity against of E. coli using well diffusion method. This research used edible coating from palm starch and Lactobacillus casei in the various concentration (10-10 ,10-11 dan 10-12) as probiotic. In this observation, we have measured the physical characteristic of edible coating, such as color test, water content, viscocity and viability of probiotic in edible coating. Color of edible coating change from clear to turbid after incorporated with Lactobacillus casei. Water content and viscocity were changed from 12.54 % (w/w) to 14.36 % (w/w) and 1426 cP to 1343 cP respectively. The best result of probiotic viability after layered on grape surface was 10-10 CFU/mL. Lactobacillus casei in edible coating before and after covered on grape surface were 131 and 159 CFU/mL respectively. Organoleptic estimation has been tested on color and flavor by 30 panelist. Data was analyzed using Anova variance statistical.Organoleptic test showed no significance estimation on grape before and after covered with edible coating. Inhibition zone of Lactobacillus casei in edible coating was 358.941 mm2. The content of organic acid in edible coating solution was measured with gas chromatography (GC) method. Organic acids detected in edible coating solution were acetate acid, butyric acid, lactic acid and propionic acid.
