Abstract

This study aimed to examine the effect of fermentation methods on the quality of Lycium barbarum and Polygonatum cyrtonema compound wine (LPW) by combining non-targeted metabolomic approaches with chemometrics and path profiling to determine the chemical and metabolic properties of LPW. The results demonstrated that SRA had higher leaching rates of total phenols and flavonoids, reaching 4.20 ± 0.10 v/v ethanol concentration. According to LC-MS non-targeting genomics, the metabolic profiles of LPW prepared by different mixtures of fermentation methods (Saccharomyces cerevisiae RW; Debaryomyces hansenii AS2.45) of yeast differed significantly. Amino acids, phenylpropanoids, flavonols, etc., were identified as the differential metabolites between different comparison groups. The pathways of tyrosine metabolism, biosynthesis of phenylpropanoids, and metabolism of 2-oxocarboxylic acids enriched 17 distinct metabolites. SRA stimulated the production of tyrosine and imparted a distinctive saucy aroma to the wine samples, providing a novel research concept for the microbial fermentation-based production of tyrosine.

摘要

本研究旨在通过结合非靶向代谢组学方法与化学计量学和路径分析,考察发酵方法对枸杞、黄精复合酒(LPW)质量的影响,以确定 LPW 的化学和代谢特性。结果表明,SRA 在 4.20±0.10 v/v 乙醇浓度下具有更高的总酚和类黄酮浸出率。根据 LC-MS 非靶向基因组学,不同发酵方法(酿酒酵母 RW;汉逊德巴利酵母 AS2.45)组合制备的 LPW 的代谢谱差异显著。鉴定出氨基酸、苯丙素、黄酮醇等为不同比较组之间的差异代谢物。酪氨酸代谢、苯丙素生物合成和 2-氧羧酸代谢途径富集了 17 种独特的代谢物。SRA 刺激酪氨酸的产生,并赋予酒样独特的鲜美香气,为基于微生物发酵生产酪氨酸提供了新的研究思路。
