Pengaruh Lama Penyimpanan Terhadap Bakso Daging Sapi yang Diformalin Secara Visual, Organoleptik, Kimiawi, dan Fisik

Abstract

The aim of this research was to analyze the effect of storage time on beef balls preserved by formalin using visual, organoleptic, chemical and physical methods. The research had been performed using factorial completely randomized design with two factor i.e; formalin concentration (K): 0, 100, 1000, and 10.000 ppm and storage time (L): 0, 1, 2, and 3 days. Parameter analyzed where visual value (with picture), physical test (moisture content and weight change), organoleptic test (texture, colour, and formalin smell), and chemical test. The result showed that formalin concentration had highly significant effect on the texture, colour, and formalin smell but had no significant effect on the moisture and weight change. The storage time had highly significant effect on the moisture content, texture, colour, and formalin smell but had no significant effect on the weight change. The interaction of the formalin concentration and the storage time had highly significant on the texture, colour, and formalin smell but had no significant effect on the moisture content and weight change. Beef balls preserved by formalin can be detected by its hard texture and formalin smell, also with chemical test using Tollens reagent and KMnO4 0,1 N + NaHSO3 0,1 N indicat
