贺兰山东麓不同子产区马瑟兰葡萄果实品质差异分析OA
Analysis of fruit quality differences in Marselan grapes among sub-producing areas of eastern foot of Helan Mountain
以贺兰山东麓银川、贺兰、永宁、青铜峡4个子产区的马瑟兰葡萄果实为研究对象,系统分析其常规理化指标、有机酸、花色苷及挥发性风味物质组成,并通过方差分析和正交偏最小二乘判别分析(orthogonal partial least squares-discriminant analysis,OPLS-DA)进行综合评价.结果显示,各子产区果实理化指标存在显著地域分异,永宁产区还原糖含量达176.94 g/L,贺兰产区可溶性固形物含量最高(26.79 °Brix),银川产区总酸含量(3.82 g/kg)显著高于其他产区.有机酸以苹果酸和酒石酸为主,其中永宁产区酒石酸含量(9.52 g/kg)、青铜峡产区苹果酸含量(3.03 g/kg)表现突出.花色苷分析表明,锦葵色素-3-O-葡萄糖苷为主要成分,在贺兰与永宁产区含量显著高于其他产区.共鉴定出95种挥发性风味物质,银川产区总含量最高(47 386.15 μg/L),以醇类和酯类为主,苯乙醇含量达8 840.56 μg/L;各产区共有挥发性风味物质为27种,OPLS-DA显示丙酸异戊酯、2-壬酮等为产区区分的关键标志物(变量投影重要性值大于1).该研究明确了贺兰山东麓不同子产区马瑟兰葡萄的品质差异,为产区栽培优化及特色葡萄酒开发提供了理论依据.
This study systematically analyzed the conventional physicochemical properties,organic acids,anthocyanins,and volatile flavor compounds of Marselan grape berries from four sub-regions(Yinchuan,Helan,Yongning,and Qingtongxia)in the eastern foothills of Helan Mountain.Analysis of variance(ANOVA)and orthogonal partial least squares-discriminant analysis(OPLS-DA)were employed for comprehensive evaluation.Results showed significant regional differences in the physicochemical indicators among the sub-regions.The Yongning sub-region exhibited the highest reducing sugar content(176.94 g/L),while Helan had the highest soluble solids content(26.79 °Brix).Yinchuan showed a significantly higher total acid content(3.82 g/kg)compared to the other regions.Malic acid and tar-taric acid were the predominant organic acids.Yongning stood out for its tartaric acid content(9.52 g/kg),and Qingtongxia for its malic acid content(3.03 g/kg).Anthocyanin analysis revealed malvidin-3-O-glucoside as the major component,with significantly higher levels in Helan and Yongning.A total of 95 volatile flavor compounds were identified.Yinchuan had the highest total volatile content(47 386.15 μg/L),dominated by alcohols and esters,with phenethyl alcohol reaching 8 840.56 μg/L.27 volatile compounds were common to all sub-regions.OPLS-DA identified isopentyl propanoate,2-nonanone,and others(variable importance in projection(VIP)＞1)as key markers distin-guishing the sub-regions.This study clarifies the quality differences in Marselan grapes among different sub-regions of the eastern foothills of Helan Mountain,providing a theoretical basis for optimizing cultivation practices and developing distinctive wines in these areas.
