Method of evaluating sulfur compound-containing substance and method of determining volatile low molecular weight sulfur compound

摘要

Provided is a method of evaluating the freshness (the degree of oxidation and reduction) of a test substance such as agricultural products based on the analysis results of a plurality of sulfur compounds and a plurality of sulfur metabolism related compounds. Provided is a method for quantifying volatile low molecular weight sulfur compounds by liquid chromatography mass spectrometry. A method of evaluating a sulfur compound-containing substance for evaluating a plurality of test substances, comprising the steps of preparing quantitative values of a plurality of sulfur compounds and a plurality of sulfur metabolism related compounds for each test substance; A step of analyzing the analysis value of the test substance by multidimensional scaling, and creating a scatter plot with two or more species selected from the degree of redox, contribution of microbial metabolism, antioxidant ability or odor or odor And a step of evaluating the redox degree of the test substance, the contribution of the microbial metabolism, the antioxidant ability or the odor or odor based on the position on the scatter diagram, and the sulfur compound-containing substance Evaluation method of
