Lipase powder preparation and use thereof

Abstract

Disclosed is a lipase powder preparation in which the lipase particles forming a lipase powder have, on the surface, 3,000 to 40,000 pores / mm2 with a diameter in the range of 0.5 [mu]m to 6 [mu]m. The lipase powder preparation has achieved improvements in lipase activity without the use of a soybean powder.

Description

technical field [0001] The present invention relates to lipase powder preparations applicable to various esterification reactions, transesterification reactions, and the like, and to transesterification methods using these powder preparations. Background technique [0002] Lipase can be widely used in the esterification reaction of various carboxylic acids such as fatty acids and alcohols such as monohydric alcohols or polyhydric alcohols, and the transesterification reaction between various carboxylic acid esters. Among them, from the modification of animal and vegetable oils to the production methods of various fatty acid esters, sugar esters or sterol esters, transesterification is an important technology. When lipase, which is an oil hydrolyzing enzyme, is used as a catalyst for these reactions, the transesterification reaction can be carried out under mild conditions from room temperature to about 70°C. Compared with conventional chemical reactions, it can not only supp...

AI Technical Summary

Problems solved by technology

Here, the enzymes that can be used include lipase, cellulase, protease, amylase, and pectinase, and the enzyme-immobilized preparation obtained by such a production method can inhibit enzyme activity in the presence of a substance with low enzyme activity. Inactivated, but no increase in enzyme activity was documented

In addition, here, the actual manufactured product is only an example in which defatted soybean flour with a low fat content is applied to cellulase or protease, and there is no specific description of an example in which lipase is used.
