Problems solved by technology

That is, in the synthesis reaction conditions and subsequent refining methods, the sensory quality and safety such as color, smell, and taste, which are important for use as general food raw materials, health food raw materials, or pharmaceutical raw materials, are not considered.
[0016] (2) In addition, for the raw material sterols that form sterol fatty acid esters, since pure products with high purity are used as raw materials, the synthesized sterol fatty acid esters are expensive products, and it is not suitable in terms of cost when used in foods, etc. of
That is, when deodorized scum oil is directly used as raw material to synthesize sterol fatty acid ester, when using the enzyme or chemical catalyst of random catalyzed esterification reaction, owing to obtain the sterol fatty acid ester containing trans fatty acid or other inferior fatty acid, in terms of safety not preferred

Embodiment 1

[0200] 100 g of water was added to 200 g of soybean deodorized scum oil (sterol content 13% by weight), and while mixing at 40° C., lipase powder (360,000 units / g) derived from Candida was added (Lipase OF, Meito Sangyo Co., Ltd.) 2.0 g. After performing the reaction while stirring at 40° C. for 24 hours, enzyme inactivation was performed by stirring at 80° C. for 30 minutes. After performing dehydration treatment at 80° C. under reduced pressure, 1.0 g of diatomaceous earth was added, stirred, and filtered to remove enzyme protein. Next, molecular distillation was carried out using a centrifugal molecular distillation apparatus with a vacuum degree of 1.5 Pa, an evaporation surface temperature of 230° C., and a flow rate of 2.0 L / hour to remove impurities mainly composed of free fatty acids to obtain 33 g of sterol fatty acid esters. Then, as an adsorbent treatment, hexane in an amount 5 times the amount of the remaining components was added, mixed, 20% of activated clay was...

Embodiment 2

[0203] 50 g of water was added to 200 g of soybean deodorized scum oil (sterol content 13% by weight), and while mixing at 40° C., heat-resistant lipase powder (10,000 units / g) derived from Rhizopus was added (タリパゼ, Tian Bian Pharmaceutical Co., Ltd.) 3.0 g. After performing the reaction while stirring at 50° C. for 24 hours, the enzyme was inactivated by stirring at 90° C. for 30 minutes. After performing dehydration treatment at 80° C. under reduced pressure, 1.0 g of diatomaceous earth was added, stirred, and filtered to remove enzyme protein. Next, molecular distillation was performed using a centrifugal molecular distillation apparatus with a vacuum degree of 1.5 Pa, an evaporation surface temperature of 230° C., and a flow rate of 2.0 L / hour to remove impurities mainly including free fatty acids to obtain 31 g of sterol fatty acid esters. Then, as an adsorbent treatment, hexane in an amount 5 times the amount of the remaining components was added, mixed, 20% of silica g...

Embodiment 3

[0205] 100 g of water was added to 200 g of rapeseed deodorized scum oil (sterol content 8%), and while mixing at 40° C., lipase powder (360,000 units / g) derived from Candida was added (Lipase OF, Meito Sangyo Co., Ltd.) 2.0 g. After performing the reaction while stirring at 40° C. for 24 hours, enzyme inactivation was performed by stirring at 80° C. for 30 minutes. After performing dehydration treatment at 80° C. under reduced pressure, 1.0 g of diatomaceous earth was added, stirred, and filtered to remove enzyme protein. Next, molecular distillation was carried out using a centrifugal molecular distillation apparatus at a vacuum degree of 1.5 Pa, an evaporation surface temperature of 230° C., and a flow rate of 2.0 L / hour to remove impurities mainly composed of free fatty acids to obtain 28 g of sterol fatty acid esters. Then, as an adsorbent treatment, hexane in an amount 5 times the amount of the remaining components was added, mixed, 20% of activated carbon relative to t...

Abstract

Disclosed is a method for enzymatically producing sterol fatty acid ester for food, this method comprises: reaction for synthesizing the sterol fatty acid ester by deodorizing scum oil, in the presence of the enzyme which is active in fat decomposing as a catalyst, an enzyme deactivation treatment, dehydration treatment and enzymatic protein removal treatment, the impurity is removed by molecular distillation treatment, adsorbent treatment, and steam distillation treatment, thus obtaining the sterol fatty acid ester for foods excellent in terms of both appearance and safety.

Description

technical field [0001] The present invention relates to an enzyme production method of a sterol fatty acid ester for food, which uses an enzyme having lipolysis activity as a catalyst to produce a sterol fatty acid ester for food from deodorized scum oil. [0002] In particular, the first invention relates to an enzyme production of a sterol fatty acid ester for food which has physiological activity and an inexpensive food sterol fatty acid ester from deodorized dross oil by using an enzyme having lipolysis activity such as lipase as a catalyst. method. [0003] Moreover, 2nd invention relates to the manufacturing method of the sterol fatty acid ester for food which manufactures the sterol fatty acid ester for food at low cost from deodorized dross oil. [0004] In addition, the third invention relates to a method for producing sterol fatty acid esters for food at low cost from deodorized dross oil, and particularly relates to the production of sterol fatty acid esters for fo...
