白酒陈酿机理及人工催陈技术研究进展OA

Aging is a crucial process for improving the sensory quality and promoting flavor harmony of freshly distilled Baijiu.Traditional natural aging can effectively promote liquor quality improvement,but it is restricted by long storage cycles and high economic costs.This review systematically summarizes the aging mechanisms of Baijiu and the core physical and chemical variations occurring during the aging,including ethanol-water molecular association,volatilization of low-boiling-point compounds,esterification-hydrolysis,oxidation-reduction,and acetal formation,and highlights the current development status of artificial aging technologies.On this basis,this review further systematically analyzes the research progress in combined aging and novel aging technologies and proposes future research prospects,covering multi-physical field coupled aging,intelligent process regulation,and the construction of standardized evaluation systems,combined with the development trend of intelligent manufacturing and digital technology in the Baijiu industry,aiming to provide a theoretical reference for the in-depth exploration of Baijiu aging mechanisms and the development of efficient artificial aging technologies.
