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.
