Pemanfaatan Pati Ubi Jalar Merah Sebagai Edible Coating dan Pengaruhnya terhadap Mutu Buah Strawberry Selama Penyimpanan

Abstract

The objective of this research was to find out the effect of the concentration of red sweet potato starch in the manufacture of edible coating on strawberry fruit quality during storage. Method used in this research was completely randomized design (CRD) with 2 factors, namely the concentration of starch (P) : (0%, 2.5%, and 5%) and storage time (L) : (0 days, 3 days, 6 days, and 9 days. Parameters analyzed were weight loss, total soluble solid, vitamin C, total acid, total microbes, coating thickness, color values, organoleptic values of color, taste, aroma, and texture. The results showed that starch concentration had highly significant effect on weight loss, total soluble solid,, vitamin C, total acid, total microbes, coating thickness, color values, organoleptic values of color, flavor,aroma and texture. Interaction of starch concentration and storage time had highly significant effect on weight loss, had significant effect on total acid and the thickness of the coating. Edibel coatings which produce the best strawberry fruit quality was 2.5% of starch concentration and storage time of 3 days.
