基于元素含量和稳定同位素比值的宁夏贺兰山东麓地区有机葡萄酒甄别
Differentiation between Organic and Non-Organic Wines from Helan Mountain East Region Based on Elemental Contents and Stable Isotope Ratios
摘要
Abstract
In this study,we analyzed elemental contents and stable isotope ratios of carbon (C) and nitrogen (N) in organic and non-organic wines from Helan mountain east region in Ningxia of China and then used the obtained data to distinguish between the two wines.Our results showed that there were significant differences in the contents of several metal elements including Na,Mg,K,A1 and Cu between the organic and non-organic wines and that the δ13C ratios of ethyl alcohol and glycerol in the organic wine were much lower than those in the non-organic one,but the N stable isotope ratios were significantly higher than those in the non-organic one.Thus,C and N stable isotopes and the contents of selected metal elements could be used to effectively distinguish between organic and non-organic wines by principal component analysis.This method has a great potential to be applied for organic wine authentication and therefore can provide a technical support for the development of the wine industry in this region.关键词
