Edible Film Kaya Antioksidan, Vitamin C dan Polifenol Bebasis Beras Menir dengan Variasi Penambahan Bubuk Daun Kelor dan Gliserol

Abstract

Edible film is a type of packaging that can be directly consumed because it is made from plant-based materials that are safe for consumption. The development of edible film is currently leaning towards active packaging. Based on this, there is an opportunity to make strong and elastic edible film by adding glycerol plasticizer and active compounds such as moringa leaf powder. Edible film is made with the basic ingredients of broken rice starch, with the aim of knowing the effect of adding glycerol and moringa leaf powder on water content, polyphenol content, vitamin C content, and antioxidant activity of edible film. This edible film research used a Completely Randomized Design (CRD) with two factors, namely glycerol ratio (A) and moringa leaf powder ratio (B). The glycerol ratio factor was obtained (ml per weight of broken rice) which consisted of three levels, namely 1,5:15 (A1), 2,25:15 (A2), and 3:15 (A3). The ratio factor of the addition of moringa leaf powder was obtained (g per weight of broken rice) which consisted of three levels, namely 2:15 (B1), 3:15 (B2), 4:15 (B3). The results of the study on edible films made from broken rice showed that the interaction between glycerol and Moringa leaf powder had a significant effect on the results of water content, polyphenol content, vitamin C content, and antioxidant activity. Edible films made from broken rice with various concentrations of added moringa leaf powder and glycerol had water content ranging from 10.48% to 16.45%, polyphenol content of 0.82 mg GAE/g to 1.25 mg GAE/g, vitamin C content of 0,19% to 0,53%, antioxidant activity of 21.84% to 48.14% and a total yield of 4.24% to 4.86%.
