Abstract
Indonesian nutmeg has aflatoxin levels above European Union standards, namely B1 6.4 - 120 mikrogram/kg and total aflatoxins of 10.1 - 140 mikrogram/kg. Many factors cause Aspergillus flavus contamination such as mixing old and young nutmeg, sanitation, drying places and storing places for nutmeg. This study aims to obtain a technology package to reduce aflatoxins in nutmeg. This study used a completely randomized factorial design with 3 treatment factors, namely shell-free drying (A1), shell-drying (A2), combination of liquid smoke + clove leaf flour(B1), Liquid smoke + bitter leaf flour and (B2), Storage duration of 1 month (C1), storage duration of 2 months (C2), storage duration of 3 months (C3) then repeated 3 times. The results showed that the moisture content of nutmeg with a combination of treatments for each factor with 1 month of storage was 1.4%, 2 months of storage was 10.2% and 3 months of storage was 11%. Aflatoxin B1 contamination <3.86 mikrogram/kg, B2 <1.11 mikrogram/kg, G1 <3, 86 mikrogram/kg and G2 <1.11 mikrogram/kg and the total aflatoxin was <9.94 mikrogram/kg. The Proximate test shows the test value of fat 32.09, protein 5.54, carbohydrates 47 and ash 1.46. The test for the presence of negative foreign objects on the results of treatment of nutmeg seeds with vegetable ingredients. A drying technology package and the use of vegetable ingredients can be recommended to reduce aflatoxin contamination.
