Patent ID: 7981641

Claim:
A process for enzyme-catalyzed production of triglycerides comprising: (a) reacting one or more polyunsaturated fatty acids and/or C 1-4 alkyl esters thereof with glycerol in vacuo in the presence of at least one enzyme to form triglyceride and at least one partial glyceride intermediate product, wherein the reaction is accelerated by addition of at least one additive, wherein the additive is selected from the group consisting of weakly basic salts, complexing agents, and salts of acidic ion exchangers; (b) removing the enzyme from the triglyceride; and (c) removing remaining fatty acids and/or C 1-4 alkyl esters thereof from the triglyceride, wherein the enzyme is selected from the group consisting of lipases, phospholipases, and esterases; wherein the weakly basic salt is selected from the group consisting of sodium carbonate, sodium citrate, sodium acetate, sodium phosphate, potassium carbonate, potassium citrate, potassium acetate, and potassium phosphate; and wherein the complexing agent is selected from the group consisting of EDTA free acid, EDTA disodium salt, EDTA tetrasodium salt, and trinitriloacetic acid trisodium salt.
