Abstract

Objective of the research was to determine chemical, physical, microbiology and organoleptic characteristics of fermented mustard. The research was conducted from September to November 2016 at Chemical Laboratory of Agricultural Products, Food Microbiology Laboratory and Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University, Indralaya. his research used a factorial completely randomized design with two factors and it was done in triplicates. The factors were salt consentration (2.5, 5.0and 7.5%) and temperature variation (20oC and 30oC). Observed parameters were chemical (pH value and total acid content), physical (color), microbiology (total lactic acid bacteria) characteristics, Organoleptic test used hedonic test for aroma, color and texture. The research showed that salt consentration significantly affected pH, total acid content, color (lightness, redness and yellowness) and total lactic acid bacteria,while temperature variation significantly affected pH, total acid content and total lactic acid bacteria. Furthermore, the interaction of the two factors showed significantly affected on total lactic acid bacteria. The best treatment was A2B2 sample (5.0% salt and 30oC temperature) with the following characeristics: 3.72 for pH, 4.60% for total acid content, 36.58% for lightness, 3.22 for redness, 15.30 for yellowness, 7.24 log cfu/mL for total lactic acid bacteria and hedonic score (aroma 2.48, color 2.56 and texture 2.64).
