SIFAT FISIKO-KIMIA KEMASAN BERBASIS GELATIN DENGAN VARIASI PENAMBAHAN GLISEROL DAN EKSTRAK DAUN KERSEN (Muntingia calabura)

Abstract

antivirus, antihipertensi, fisiko-kimia kemasan berbasis gelatin dengan variasi gliserol ekstrak kersen. Kemasan berbasis gelatin dibuat dengan variasi penambahan gliserol 10%;20%;30% ekstrak kersen berbeda yaitu 5%;10%;15%. Parameter dianalisis tarik, persen kelarutan, kadar air aktivitas antioksidan. gliserol kersen sifat fisiko-kimia meningkatkan nilai kuat tarik ( tensile strength ), meningkatkan nilai persen ( elongasi ) meningkatkan nilai persen kelarutan, meningkatkan nilai kadar air, meningkatkan nilai aktivitas ABSTRACT Packaging that calabura). Gelatin-based packaging was made with variations in the addition of glycerol 10%; 20%; 30% and different cherry leaf extracts, namely 5%; 10%; 15%. Parameters analyzed were thickness test, tensile strength, percent elongation, solubility, water content and antioxidant activity. The treatment of variations in the addition of glycerol and cherry leaf extract to the physico-chemical properties resulted in increasing the thickness value, decreasing the tensile strength value, increasing the percent elongation value and increasing the solubility percent value, increasing the water content value, and increasing the antioxidant activity value. packaging.
