doi:10.7506/spkx1002-6630-201124020

Abstract

Abstract: For the structural modification of the seed oil of Momordica charantia L, its reaction with capric acid was carried out in the presence of lipozyme RM IM as catalyst, resulting in a decrease of eleostearic acid level in it. Reaction conditions such as molar ratio of the oil to capric acid, enzyme dosage, temperature and reaction time were identified as main factors that affect capric acid content in modified oil, and were optimized by response surface methodology to be 1:4, 12.5%, 60 ℃ and 14.8 h, respectively. The content of capric acid in the new oil synthesized under these conditions was 47.12%, and the eleostearic acid 25.46% compared with 56.17% in the native seed oil of Momordica charantia L.

Key words: lipase-catalyzed, capric acid, structured lipid, Momordica charantia L. seed oil, response surface methodology
