AN ENZYMATIC PROCESS FOR THE ISOLATION OF ERUCIC ACID FROM VEGETABLE OILS
Patent Number: 5633151
Docket Number: 9495
Serial Number: 8406829
Date Patented: 05/27/1997
Agency:
Agricultural Research Service
Issued:
May 27, 1997
Abstract:
The invention involves the production of erucic acid from oilseeds, such as rapeseed, that
can be used in a variety of industrial applications. The invention is an environmental
alternative in the manufacture of products such as lubricants, fabric softeners and personal
care products. The invention uses enzymes derived from the fungi Geotrichum candidum
or Candida rugosa to obtain erucic acid by hydrolysis. Fatty acid substituents having
carbon chains shorter than C22 are removed from triglycerides which also contain one or
two erucic acid substituents, resulting in a glyceride fraction enriched in erucic acid and a
free fatty acid fraction containing the hydrolyzed substituent.
