摘要:
A process for enzymatically producing, from a vegetable oil deodorizer distillate, a dietary sterol fatty acid ester superior in flavor qualities (e.g., color, odor and taste) and safety and containing no or little trans fatty acids, wherein the conditions for treatment of the starting material, synthetic reaction and subsequent purification are controlled so that the sterol fatty acid ester becomes applicable as a daily food material, a health food material or a pharmaceutical material. In the process, fatty acid esters, e.g., triacylglycerol, in the vegetable oil deodorizer distillate are previously degraded by hydrolysis with a chemical catalyst, fatty acids produced in the hydrolysis are removed by molecular distillation to give a sterol-containing fraction. The sterol-containing fraction is added with any fat and oil primarily comprising triacylglycerol. The mixture is used as the starting material, and the synthetic reaction is performed under strictly controlled conditions using a lipolytic enzyme. The resulting product undergoes several steps of purification process to provide qualities suitable for a food material.

[Problem] To provide: a method for selectively and easily quantifying an amino acid to be measured (L-form or D-form amino acid) with high sensitivity using aminoacyl-tRNA synthetase (AARS); and an amino acid quantification kit. [Solution] The present invention pertains to: a method for quantifying an amino acid (L-form or D-form amino acid) in a sample by means of AARS, said method being characterized in that AARS and an amino acid are released from an aminoacyl-AMP AARS complex once formed and are used once again for forming an aminoacyl-AMP AARS complex so as to ultimately produce a reaction product such as pyrophoric acid to be measured in an amount that is greater in terms of the number of moles than the amino acid included in the sample; and an amino acid quantification kit for implementing said method.
