A lipase powder which is a granulated substance containing a lipase and a solid content of animal milk, a lipase composition wherein said lipase powder is immersed or impregnated in fatty oil, and a method for producing the lipase powder which comprises the step of adding animal milk or cream derived from the animal milk to an aqueous solution containing a lipase, and the step of spray-drying, freeze-drying or solvent-precipitating the mixture thereof are provided. According to the present invention, a lipase powder of which lipase activity and stability are improved can be provided.

Lipase powder, methods for producing the same and use thereof

There is provided a lipase composition comprising (a) a powdered lipase which is a lipase derived fromsp. or a powdered lipase which is a lipase derived fromsp. and (b) a powdered lipase selected from the group consisting of a powdered lipase which is a lipase derived fromsp., a powdered lipase which is a lipase derived fromsp. and a powdered lipase which is a lipase derived fromsp. When using this lipase composition, a compound(s) having at least one alcoholic hydroxyl group in the molecule can be effectively esterified with a carboxylic acid(s).

Lipase powder composition and a process for preparing an esterified compound by using the same

A method for producing symmetric triglycerides, which comprises the steps of reacting a medium chain fatty acid triglyceride with a long chain fatty acid triglyceride in the presence of an enzyme or a chemical catalyst to conduct random transesterification reaction and thereby to obtain a reaction product containing a triglyceride composed of a medium chain fatty acid and a long chain fatty acid as the constituting fatty acids in the step of the first reaction; transesterifying the reaction product with an alcohol monoester of the medium chain fatty acid in the presence of an sn-1,3-position specific enzyme in the step of the second reaction and then taking the alcohol monoester of the medium chain fatty acid and the alcohol monoester of the long chain fatty acid from the reaction product obtained in the step of the second reaction to obtain the symmetric triglyceride composed of the medium chain fatty acids at the sn-1, 3 positions and the long chain fatty acid at the sn-2 position. According to this method, highly pure symmetric triglycerides comprising a medium-chain fatty acid at sn-1 and 3 positions and a long chain fatty acid at sn-2 position can be industrially efficiently produced.
