Maotai-flavor liquor endogenous oligopeptide and application thereof

The invention discloses a Maotai-flavor Baijiu endogenous oligopeptide and application thereof, and belongs to the field of Baijiu brewing. According to the preparation method of the endogenous oligopeptide Tyr-His-Tyr (YHY) in the Maotai-flavor liquor finished product, oligopeptide interacts with flavor substances in the Maotai-flavor liquor, a gas phase detection result verifies the conjecture, it is found that the volatility of alkyd ester flavor substances in the Maotai-flavor liquor can be influenced by addition of oligopeptide, and the flavor substances in the Maotai-flavor liquor can be used for preparing the endogenous oligopeptide Tyr-His-Tyr (YHY). Therefore, a direction is provided for researching and further exploring a binding mechanism of oligopeptide and flavor substances in Baijiu in the future. 本发明公开了一种酱香型白酒内源性寡肽及其应用，属于白酒酿造领域。本发明提供酱香型白酒成品酒中内源性寡肽Tyr-His-Tyr(YHY)的制备方法，寡肽与酱香型白酒中风味物质存在相互作用，气相检测结果对这一猜想进行了证实，发现寡肽的加入会影响酱香型白酒中醇酸酯类风味物质的挥发性，这将为今后的研究和进一步探索白酒中寡肽与风味物质的结合机制提供方向。
