中文摘要： 针对目前市场上樱桃酒产品档次低，香气、口感差，特征风味形成规律性不明确的问题。本项目旨在通过研究樱桃酒的发酵机制，阐明发酵过程参数与特征风味物质的种类、含量的关系，探究樱桃酒特征风味物质的形成原因，获得樱桃酒特征风味的形成规律，从而有效调控反应过程。以固定来源的樱桃为主要原料，重点考察发酵温度、酵母添加量、二氧化硫添加量、pH值等对樱桃酒风味的影响及作用机制，并结合化学计量学理论体系中的化学模式识别和多维校正方法，系统研究特征风味物质的形成机理，探索樱桃酒特征风味的形成规律，并用其指导设计理想的发酵体系，实现对樱桃酒特征风味的有效调控。而通过理论和实验相结合的方法研究樱桃酒的发酵机制与其特征风味形成规律，除本课题组发表的文章和预研工作外，尚未见国内外文献报道。通过本项目的研究，不仅可以实现樱桃酒特征风味的有效调控，而且有助于丰富和发展樱桃酒的酿造理论。

英文摘要： At present ,there exist some problems in the cherry wines, such as low-grade,poor aroma,taste and characteristic flavor,irregularity of forming characteristic flavor. For these problem mentioned above, this project aims to indicate the relationship between fermentation parameters and characteristic flavor compounds, find the reasions of effecting flavor by studying the action mechanism.Finally, the regularity of forming characteristic flavor is obtained in order to control the reaction process. The influence and action mechanism of the fermentation temperature, adding amount of yeast,SO2 and pH value ,etc, on the flavor of cherry wine were mainly studied , with cherry from the same region as raw materials. Forming mechanism of characteristic flavor compounds was study by chemical pattern recognition and multi-dimensional correction method of chemometrics theoretical system. Regularity of forming characteristic was studied in order to desigin better fermentation system to control the cherry wine flavor effectively. In addition to this pre-research work in this topic ,few research has been reported at home and abroad. Regurity of forming characteristic flavor was obtained and control the characteristic flavor through the study.And it also can enrich and develop cherry wine brewing theory.
