Abstract

Production an edible films packaging is a rather new food preservation approach. Many research has been carried out and have shown the extended shelf life and improved the quality of food products. One of the safest edible films for food was made from gelatin. In this study, we have produced the gelatin from catfish bone wastes, demineralization was carried out using 4% HCl for 5 hours until it reached a pH of 5, extracted by distilled water for 5 hours with the temperature of 700C where the ratio of catfish bone ossein: aquadest was (1: 2 w/w). The turmeric was extracted using the maceration method with 96% methanol for 2 days. The filtrate was evaporated, then impregnated into gelatin as specific for a gram-positive bacteria Escherichia coli. The formula for edible films was prepared with the ratio of catfish bone ossein: distilled water: turmeric extract (10:50) w/w with turmeric 0%; 5%; and 10 %. The edible films were then applied to apples. The efficacy of the existing films was improved by turmeric against Escherichia coli bacteria for the coming 20 days was studied using the modified disc method. The acceptance test of film products was carried out using the organoleptic method.
