Problems solved by technology

At present, domestic research on wine fingerprints mainly focuses on wine aroma components, but a single aroma component is not enough to comprehensively measure the quality of wine, and the characteristic fingerprints of aroma components produced are not strong enough to effectively analyze Wine origin and quality are screened

Abstract

The present invention relates to a method for tracing an import Merlot grape wine production place by using a dual finger print technology. According to the method, HPLC-MS is adopted to establish a finger print of an ethyl acetate extract in an import Merlot grape wine, a GC-MS method is adopted to establish a finger print of a dichloromethane extract in the import Merlot grape wine, a production place of the import grape wine can be traced by combining the two finger print technologies and utilizing a traditional Chinese medicine finger print evaluation software to carry out data processing, and the obtained result can be adopted as one of import Merlot grape wine quality assessment indicators. The analysis method has advantages of sensitivity, accuracy, stability, high precision, good reproducibility and the like.

Description

technical field [0001] The invention relates to a method for analyzing wine HPLC-MS and GC-MS fingerprints, relates to a method for tracing the origin of imported Merlot wine and evaluating its quality, and belongs to the field of food chemical analysis. Background technique [0002] Wine is a worldwide alcoholic beverage with a history dating back more than 7,000 years. Wine plays an important role in the economies of many countries. Wine is more and more popular because it contains more than 1,000 beneficial substances such as water, sugar, alcohol, glycerin, organic acids, esters, and various minerals. The main production areas of wine are mainly distributed in Europe, America, Australia and other places. The main production areas of my country are mainly in Yantai, Shandong, Changli, Hebei, Siping, Jilin, Yingkou, Liaoning and other places. In recent years, due to factors such as rising liquor prices and changes in the eating habits of the younger generation, domestic ...
