Food Metabolomics Evaluation of Japanese Rice Wine Types Using LC/MS/MS

Introduction

Metabolomics is an increasingly well-known technology for comprehensively analyzing in vivo metabolites. Food metabolomics is an application of this technology. Conventionally, sensory analysis conducted by human assessors to evaluate tastes, aroma, deliciousness, grades, etc. has been the main method of food evaluation. Food metabolomics is used to scientifically "evaluate/predict the quality" of food and "explore functional ingredients" by comprehensively analyzing the metabolites in food and then analyzing the relationship between the analysis results and the results of evaluations conducted by humans such as sensory analysis. As an example of food metabolomics, this article introduces an analysis of five types of specially designated Japanese rice wine (sake). In this study, we comprehensively analyzed the hydrophilic components of sake samples with a high performance liquid chromatograph mass spectrometer (LC/MS/MS) and verified the characteristics of each sake type.
