Abstract
The invention relates to a process for the preparation of EPA and DHA enriched glycerides from degummed oil using microbial lipase enzymes. It particularly relates to the use of very less concentrations of said enzymes and water for the hydrolysis process. Used lipase enzymes specifically removes non-EPA/DHA fatty acids which results in enriched and balanced content of EPA/DHA in to the final product.
Claims10
A process of the preparation of EPA and DHA enriched glycerides from crude degummed fish oil comprising:
- a) mixing said oil with water forming a reaction mixture;
- b) heating said mixture at desired temperature with continuous stirring;
- c) contacting said reaction mixture with lipase for desired time;
- d) separating fraction of water from said mixture forming a first stream;
- e) evaporating said first stream to remove remaining water forming a second stream;
- f) subjecting said second stream to molecular distillation at desired conditions to separate free fatty acid as a distillate forming a residual stream;
- and
- g) collecting said residual stream having said EPA DHA enriched glycerides.
