摘　　要：以贺兰山东麓3个年份两个品种的葡萄酒为试材,运用LCR仪测定其电学特性,分析不同激励电压(1、3、5 V)和不同频率(0.1、1.0、10.0、100.0、1000.0 kHz)下葡萄酒间电学特性的差异,筛选出识别年份葡萄酒的最适激励电压、频率和有效电学参数,探索利用电学特性识别贺兰山东麓年份葡萄酒的可行性。结果表明,在本研究中葡萄酒电学参数在不同电压下随频率的增加变化趋势一致,但不同年份间分离程度有所差异。在本研究中,随着频率的增加,葡萄酒电学参数Z值和Cp值逐渐减小,G值逐渐增加,θ值先增后减,B值则先减后增;而D值仅‘赤霞珠’葡萄酒在1 V+0.1 kHz条件下存在显著差异。通过多元统计分析,LCR仪在5 V激励电压+1.0 kHz频率条件下,能够利用Z、Cp、G、θ和B这5个电学参数来识别贺兰山东麓‘赤霞珠’和‘雷司令’年份葡萄酒。Three vintage wines of two varieties from the eastern foot of Helan Mountains were used as test materials,their electrical characteristics were measured by LCR instrument,and the differences of electrical parameters among wines were analyzed under different excitation voltages(1,3,5 V)and different frequencies(0.1,1.0,10.0,100.0,1000.0 kHz).The optimum excitation voltage,frequency and effective electrical parameters were selected to identify vintage wines in order to explore the feasibility of using electrical characteristics to identify vintage wines at the eastern foot of Helan Mountains.The results showed that the electrical parameters of wines had the same trend with the increase of characteristic frequency under different voltages,but the degree of separation was different between vintage wines.In this researh,with the increase of frequency,Z value and Cp value of wine electrical parameters gradually decreased,G value gradually increased,θvalue increased first and then decreased,B value decreased first and then increased.The D value was significantly different only in'Cabernet Sauvignon'wine with 1 V+0.1 kHz condition.According to multivariate statistical analysis,the LCR analyzer can identify'Cabernet Sauvignon'and'Riesling'wine of eastern foot of Helan Mountains by using five electrical parameters including Z,Cp,G,θand B under the condition of 5 V voltage+1 kHz characteristic frequency.
