Abstract
The present invention is directed to improving productivity of an enzymatic method for making esterified, transesterified or interesterified products. Specifically, a method that can greatly improve the productivity of enzymatic transesterification or esterification by deodorization alone, or by deodorization and purification of the initial substrate to extend the useful life of the enzyme is disclosed.
Claims40
A method of making an esterified, transesterified or interesterified product comprising:
- (a) deodorizing an initial substrate, wherein said initial substrate comprises one or more fats or oils and contains constituents that cause or arise from fat or oil degradation, thereby reducing the constituents which cause or arise from fat or oil degradation in said initial substrate and thereby producing a deodorized substrate;
- (b) contacting said deodorized substrate with a fat or oil modifying enzyme thereby making said esterified, transesterified or interesterified product;
- wherein the half-life of said enzyme is prolonged.
