Abstract

Preference of Rhizomucor miehei lipase (EC 3.1.1.3) in the incorporation of 11 fatty acids (FA; C10:0 to C22:6) into coconut oil triacylglycerols (TAG) during acidolysis was studied by applying the Plackett-Burman experimental design. Enzymic acidolysis reactions were carried out in hexane at 37C for 48 h with coconut oil (0.1M) and a mixture of 11 FA at a TAG to FA molar ratio of 1:1. Lipase was used at the 5 wt.% level. Incorporation of FA into coconut oil TAG was determined by GC. The lipase showed preference for long-chain saturated FA for incorporation into coconut oil TAG. The FA with 18 C atoms showed a high incorporation rate (18:0 > 18:1 > 18:3). Lipase showed the lowest preference for incorporation of 12:0, which occurred at max. concn. (46%), whereas the most preferred FA, 18:0, occurred at a very low concn. (<less than or equal to> 2%) in coconut oil. The overall preference of lipase for incorporation of different FA into coconut oil TAG was 18:0 > 18:2, 22:0 >18:1, 18:3, 14:0, 20:4, 22:6 > 16:0 > 12:0 >> 10:0.
