Solvent‐free enzymatic glycerolysis of marine oils
Abstract Marine triglyceride oils (cod liver oil and oils from blubber of harp seal and minke whale) were reacted with glycerol using lipase as a catalyst at low temperature. A solvent‐free batch system with magnetic stirring was used. Solidification of the reaction mixture occurred, and a mixture o...
