摘要
[目的]为确定黑比诺酿酒葡萄的核心品质指标,建立黑比诺酿酒葡萄品质综合评价模型.[方法]在河西走廊武威市凉州区、武威市民勤县、嘉峪关市和张掖市4个产区5个产地代表性果园共采集5份黑比诺葡萄果实样品进行品质测定,通过主成分分析和聚类分析法确定黑比诺葡萄核心品质指标,运用层次分析法确定指标权重并建立'黑比诺'葡萄品质综合评价模型.[结果]不同产地果实基本品质、糖酸组分和香气物质总含量存在明显差异,综合主成分分析和聚类分析分析结果,构建了黑比诺葡萄品质综合评价公式为:Y(综合得分)=0.408 3×可溶性固形物含量的标准化值+0.176 3×香气物质种类的标准化值+0.118 8×奎宁酸含量的标准化值+0.296 7×可滴定酸含量的标准化值.[结论]综合分析得出,武威市凉州区清源镇'黑比诺'葡萄综合品质较好,而武威市民勤县收成镇黑比诺香气物质积累较多.
Abstract
[Objective]A comprehensive Pinot Noir grape quality assessment model has been developed to determine the key quality indicators of Pinot Noir wine grapes.[Method]A total of 5 samples of Pinot Noir grapes were collected from 5 representative orchards in Liangzhou District of Wuwei City,Minqin County of Wuwei City,Jiayuguan City and Zhangye City in 4 production areas of the Hexi Corridor.Deter-mine the core quality indicators of Pinot Noir grapes by principal component analysis and cluster analysis,determine the weights of the indicators by hierarchical analysis,and establish a comprehensive evaluation model of the quality of Pinot Noir grapes.[Result]There were obvious differences in basic quality and the hierarchical analysis method was used to construct a comprehensive quality evaluation formula for Pinot Noir grapes.The evaluation formula was as follows Y(comprehensive score)=0.408 3×standardized value of soluble solids content+0.176 3×standardized value of aroma substance type+0.118 8×stan-dardized value of quinic acid content +0.296 7×standardized value of titratable acid content.[Conclusion]The comprehensive analysis concluded that the overall quality of Pinot Noir grapes from Qingyuan Town,Liangzhou District,Wuwei City was better,while Pinot Noir from Shoucheng Town,Minqin County,Wu-wei City had a higher accumulation of aroma substances.
