1H 的联合原子磁性的回声(NMR ) 光谱学和主要部件分析(PCA ) 为是为类型,生产起源或酒的地理起源的分类的一个有用方法显示出潜力。在这初步的研究, 21 装的酒为他们生产的地点被分类 / 分开在 Shacheng, Changli 和 Yantai,和混合、中等干燥、干燥白人和干燥的红酒的类型,用 NMR-PCA 方法。酒被一家企业的三个辅助公司根据一样的国家标准生产。分离被相信主要由于为不同的酒和环境变化的发酵过程,例如本地气候,土壤,地下的水,日光和降雨。与分离联系的主要化学药品被识别。
A combination of ^1H nuclear magnetic resonance (NMR) spectroscopy and principal component analysis (PCA) has shown the potential for being a useful method for classification of type, production origin or geographic origin of wines. In this preliminary study, twenty-one bottled wines were classified/separated for their location of production in Shacheng, Changli and Yantai, and the types of the blended, medium dry, dry white and dry red wines, using the NMR-PCA method. The wines were produced by three subsidiary companies of an enterprise according to the same national standard. The separation was believed to be mainly due to the fermentation process for different wines and environmental variations, such as local climate, soil, underground water, sunlight and rainfall. The major chemicals associated with the separation were identified.
