Karakteristik Fisikokimia dan Sifat Fungsional Tempe yang Dihasilkan dari Berbagai Varietas Kedelai

Abstract

Tempe is an Indonesian traditional food made by fermentation of soybean by the fungus Rhizopus sp. The objective of this research was to compare physical and chemical properties of soybean and tempe made from import (Import 1, Import 2) and local (Local 1, Local 2, Local 3) soybeans. For tempe production, soybean were sorted, soaked, dehulled, cooked, and fermented. The result showed that Local 1 variety presented as the biggest size (19.53 g/100 soybean grains) and the highest cost effectiveness (0.73). Despite of those physical properties, yields of all tempe weren’t significantly different (p>0.05). Tempe made from soybean Local 1 had moisture, protein, and fat content as higher as tempe made from import soybeans. Tempe made from soybean Local 3 had the highest protein content (52.70%). The antioxidant capacity of tempe made from import and local soybeans were about 186-191 mg AEAC/g, but weren’t significantly different (p>0.05). Based on sensory evaluation of raw and fried tempe, overall tempe made from local soybeans had the same preference with tempe made from import soybeans. Tempe made from soybean Local 1 had shelf life until 2 days at room temperature and 7 days at low temperature based on sensory quality measurement.
