The Xiecun Huangjiu (XCHJ), an exemplary representation of North Huangjiu, exhibits a distinct and invigorating aroma predominantly formed during its aging period. In this study, we observed dynamic changes in 16 key aroma compounds by gas chromatography-mass spectrometry (GC-MS) during the aging of XCHJ, with compounds such as phenethylalcohol, isoamylalcohol, benzaldehyde, and ethylbenzoate initially increasing and then decreasing. Ultra-Performance Liquid Chromatography (UPLC) detected nineteen amino acids, with total content ranging from 1901.45 to 3764.45 mg/L. High-throughput sequencing indicated that and et al. were abundant in aged XCHJ. Totally, 4 bacteria and 8 fungi exhibited strong associations with aroma compounds production. Physicochemical properties were primarily interacted with , , , , and . Furthermore, co-occurrence network analysis highlighted significant interactions between , , , and amino acids. These findings provide valuable insights for the regulation of aroma in aged XCHJ.
斜桥黄酒(XCHJ)作为北方黄酒的典范,具有独特而浓郁的香气,主要在陈酿过程中形成。在本研究中,我们通过气相色谱 - 质谱联用(GC - MS)观察了斜桥黄酒陈酿过程中16种关键香气成分的动态变化,苯乙醇、异戊醇、苯甲醛和苯甲酸乙酯等成分先增加后减少。超高效液相色谱(UPLC)检测到19种氨基酸,总含量在1901.45至3764.45mg/L之间。高通量测序表明,[此处原文缺失具体微生物名称]等在陈酿的斜桥黄酒中含量丰富。共有4种细菌和8种真菌与香气成分的产生有强烈关联。理化性质主要与[此处原文缺失具体物质名称]、[此处原文缺失具体物质名称]、[此处原文缺失具体物质名称]、[此处原文缺失具体物质名称]、[此处原文缺失具体物质名称]和[此处原文缺失具体物质名称]相互作用。此外,共现网络分析突出了[此处原文缺失具体物质名称]、[此处原文缺失具体物质名称]、[此处原文缺失具体物质名称]和氨基酸之间的显著相互作用。这些发现为调控陈酿斜桥黄酒的香气提供了有价值的见解。
