    摘要:

    本研究以寧夏賀蘭山東麓5個(gè)子產(chǎn)區(qū)(銀川、青銅峽,、紅寺堡,、石嘴山和農(nóng)墾產(chǎn)區(qū))自然發(fā)酵的赤霞珠干紅葡萄酒為研究對(duì)象,測(cè)定其基本理化指標(biāo)和電學(xué)特性,,分析不同產(chǎn)區(qū)葡萄酒間電學(xué)特性的差異,,篩選出區(qū)分不同產(chǎn)區(qū)葡萄酒的特征頻率和有效電學(xué)參數(shù),初步探索基于電學(xué)特性識(shí)別寧夏賀蘭山東麓不同子產(chǎn)區(qū)葡萄酒的能力,,以期為簡捷快速有效識(shí)別產(chǎn)區(qū)葡萄酒提供新方法,。結(jié)果表明,寧夏賀蘭山東麓5個(gè)子產(chǎn)區(qū)的葡萄酒理化指標(biāo)間存在顯著性差異,,農(nóng)墾產(chǎn)區(qū)的葡萄酒可滴定酸含量最高,,而還原糖含量最低;銀川產(chǎn)區(qū)的葡萄酒揮發(fā)酸含量最低,,石嘴山產(chǎn)區(qū)的葡萄酒酒精度最高。通過相關(guān)性分析,、方差分析和多重比較,,篩選出電壓2V下,區(qū)分不同產(chǎn)區(qū)葡萄酒的電學(xué)特性特征頻率為0.1kHz,,有效電學(xué)參數(shù)為Z,、Lp、X,、Cp和Q,。主成分分析和判別分析均顯示,利用葡萄酒電學(xué)參數(shù)能夠明顯區(qū)分賀蘭山東麓5個(gè)子產(chǎn)區(qū),,采用Fisher- 判別分析建立的預(yù)測(cè)模型,,其回代檢測(cè)和交叉驗(yàn)證正確率均為100%。因此,,利用葡萄酒電學(xué)特性識(shí)別產(chǎn)區(qū)具有可行性,。

    Abstract:

    Spontaneous fermentation dry red wines of Cabernet sauvignon collected from five sub-producing areas (Yinchuan, Qingtongxia, Hongsibao, Shizuishan and Nongken) in the eastern foothills of Helan Mountain of Ningxia were selected as the materials. The basic physical and chemical indicators and electrical properties were measured, the differences of electrical properties among different producing regions were analyzed, and the characteristic frequency and effective electrical parameters to identify wines from different producing regions were screened. The aim was to explore the ability to identify wines from different sub-production areas in the eastern foothills of Helan Mountain in Ningxia based on electrical characteristics, in order to provide a method for simple, fast and effective identification of wine production regions. The results showed that there were significant differences in the physiochemical indicators of wines among the five sub-regions of Helan Mountain in Ningxia. Wine from Nongken region had the highest titratable acid content and the lowest reducing sugar content. The wine from Yinchuan had the lowest volatile acid sugar content, while the wine from Shizuishan had the highest alcohol content. Through correlation analysis, analysis of variance and multiple comparisons, the characteristic frequency of 0.1kHz and the effective electrical parameters Z, Lp, X, Cp and Q were selected to distinguish wines from different regions at 2V. The results of principal component analysis and discriminant analysis showed that the five sub-production regions of the eastern foothills of Helan Mountains could be clearly distinguished by the electrical parameters of wine. The prediction model established by Fisher-LDS had the correct rates of return test and cross validation of 100%. Therefore, it was feasible to identify wine producing region by wine electrical characteristics.
