PURPOSE: To obtain a fat which is similar to expensive vegetable buffer and is useful for chocolate by rearranging triglyceride in a rapeseed oil by using a specified cruciferous vegetable oil in the presence of satd. fatty acid under the influence of a rearranging catalyst of a specified lipase. CONSTITUTION: Triglycerice in a rapeseed oil is rearranged by using a cruciferous vegetable oil containing >=20wt.% (preferably >=35wt.%) erucic acid in the presence of satd. fatty acid, its ester or its deriv. (preferably alkylester of behenic acid) under the influences of 1,3-site selective lipase as a rearranging catalyst so as to obtain the fat of the purpose. In the obtd. fat, the 2-site is mostly possessed by oleic acid residue. The fatty acid or its deriv. about described has a chain having at least 16 carbon atoms. |
