[Various lipases for producing products enriched with polyenic acids in fish fat hydrolysis]. / Issledovanie razlichnykh lipaz dlia polucheniia produktov, obogashchennykh polienovymi kislotami pri gidrolize rybikh zhirov.

The enzymic hydrolysis of fish with lipases from various sources was studied. The lipase from the fungus Rhizopus microsporus preferentially removes saturated fatty acids, while lipase from the pyloric caeca of salmon unsaturated fatty acids upon hydrolysis of fish fats. The enzymes can be used to obtain fatty products enriched with eicosanopentaenoic acid, mono- and diacylglycerols by enzymic hydrolysis of the ivasi fat.
