Chemical and Microbiological Characteristics of Asam Drien (Fermented Durian from Aceh) Made by Various Methods

Research has been conducted to examine the chemical and microbiological characteristics of asam drien (tempoyak from Aceh) made by following various methods in Aceh. This study used completely randomized design consisting of 4 treatments: fermented durian without the addition of other ingredients/normal (A), fermented durian using turmeric (B), fermented durian using salt (C), fermented durian using salt and turmeric (D). The parameters analyzed included chemical properties (water content, pH, total lactic acid, and total sugars) and microbiological analysis (total lactic acid bacteria and yeasts). The results showed that the method of asam drien production had very significant effect on the water content, the total pH, total lactic acid, total sugar sand total lactic acid bacteria, but did not significantly affect the total yeast. There is a tendency that the number of treatment without the addition of salt produced water content, total lactic acid and total lactic acid bacteria higher. Average chemical and microbiological characteristics asam drien are as follows: 66.49% moisture content, pH 4.1, total acid 2.30%, 30.50% total dissolved solids, total lactic acid bacteria 99x10(10) CFU/g and total yeast of 18x10(6) CFU/g.
