The hydrolysis reaction of soybean oil was conducted experimentally by various source enzymes. The analytical result of hydrolysate of soybean oil showed that the compositions were linoleic acid, olic acid, palmitic acid, and stearic acid in order. The enzymes CR-E and CC-E from Candida rufosa and Candida cylindracea had two hold or more hydrolysis conversions
than those of Lipase 16, Novozyme 871, and Lipolase-100L under the same conditions. Therefore CR-E and CC-E were selected for further experiments. These two enzymes had similar ranges of optimun conditions as follows: pH 3-6, 35-45℃, and water to soybean oil ratio of 3.3 or above. They finally got conversions 95% above.

원료물질인 대두유를 산가수분해하여 지방산의 함량을 분석한 결과 linoleic acid, oleic acid, palmitic acid, stearic acid의 함량순으로 분석되었다. 동일한 조건하에 대두유의 가수분해반응 전화율을 조사한 결과 Candida rugosa와 Candida cylindracea에서 유래된 효소인 CR-E와 CC-E가 Lipase 16, Novozyme 871과 Lipolase-100 L보다 2배이상 높았다. 따라서 CR-E와 CC-E를 선정하여 반응조건에 대한 실험을 수행하였다. CR-E와 CC-E의 경우 비슷한 결과를 보여, pH 3～6, 35-45℃, 물과 대두유의 중량비가 3.3 이상이었을 때가 최적인 반응조건이었으며 95% 이상의 높은 전화율을 나타내었다.
