Provided is an oil or fat composition of high diacylglycerol content. Even when used in cooking, the cooked food has a good external appearance without darkening, and retains its inherent flavor. Even when used in cooking after storage under light-exposed conditions, the cooked food is provided with a good external appearance and flavor. The oil or fat composition is obtained by combining, at specific contents, (A) an oil or fat of high diacylglycerol content, said oil or fat having a particular composition, (B) a plant sterol and (C) a plant sterol fatty acid ester.

Oil or fat composition

A method for producing an immobilized enzyme which includes the steps of immobilizing an enzyme used for hydrolyzing fats and oils on a immobilization carrier by adsorption, bringing the immobilized enzyme into contact with an organic solvent in which fat-soluble fatty acids or the derivatives thereof have been dissolved, and adjusting the moisture content of the immobilized enzyme from 1 to 20% by weight based on the weight of the carrier.

Method for producing an immobilized enzyme for hydrolyzing fats and oils

Provided is a process for preparing an immobilized enzyme, which comprises the steps of immobilizing an enzyme used for decomposing oil & fat on a carrier, by adsorption, without drying, bringing the immobilized enzyme into contact with a fatty acid triglyceride or fatty acid partial glyceride, or mixtures thereof, and adjusting the moisture content of the enzyme to 5% to 50% by weight based on the weight of the carrier, wherein the enzyme is used for esterification.

Process for preparing an immobilized enzyme

Provided is a preparation process of diglycerides which comprises reacting a fatty acid or lower alkyl ester thereof with glycerin in the presence of an immobilized partial glyceride lipase while removing water, which is generated upon reaction, out of the system. The reaction is preferably terminated when the acid value (AV) of the reaction mixture satisfies the following range: 50R-60&#x3e;AV&#x3e;70R-150 (with the proviso that AV&#x3e;0). The present process makes it possible to efficiently prepare a high purity of diglycerides without impairing lipase activity even under reduced pressure. The present process is effective without being influenced by variations in reaction conditions such as fatty acid/glycerin ratio, reaction temperature or enzyme concentration. Particularly, even when the fatty acid/glycerin ratio is high, a high purity of diglycerides can be produced at a high reaction yield.
