Results of previous studies show that the high lauric fraction isolated from coconut endosperm is able to inhibit pathogenic and non-pathogenic bacteria. This research aims to study the addition of high lauric fraction that hydrolysed of coconut endosperm of the storability of soy milk packaging. High lauric fraction isolated from coconut milk, then the fraction analized of the fatty acid composition with gas chromatography (GC) and then used as a preservative soy milk. The fraction is added to the soy milk with concentrations of 0, 10, 15 and 20%, then stored for 3 days. Every day is observed until soy milk damaged. The results showed that the fraction isolated from coconut milk contains 50.45% lauric acid, 17.52% myristic acid, 7.02% palmitic acid, 6.46% capric acid, 5.52% caprylic acid, 5.12% linoleic acid, 1.89% oleic acid, and 0.11% caproic acid. The addition of lauric acid-rich fraction of 20% were able to preserve soy milk for 2 days with a total microbe 1.00 x 104 cfu/ml, free fatty acids 0.12 m mol/ml, pH 5.05 and a balanced aroma 4 (nice).
