摘　　要：中国各产区红富士苹果糖、酸、多酚等营养品质存在差异,构建其产地溯源技术有利于实施产区保护、特色产品保真及产业可持续发展。本文对新疆阿克苏、甘肃静宁、陕西洛川、河南灵宝、山东烟台和云南昭通6大产区红富士苹果的糖类、总酸及多酚类等18个营养品质指标进行检测分析,基于多元统计分析筛选有效产地溯源营养品质指标,构建红富士苹果不同产地鉴别的判别模型。结果表明,相对于其他产区,阿克苏红富士苹果总糖和山梨醇等含量偏高;静宁红富士苹果总酚和绿原酸等含量偏高;灵宝红富士苹果儿茶素和根皮素等含量偏高;洛川红富士苹果果糖和根皮苷等含量偏高;烟台红富士苹果糖酸比和芦丁等含量偏高;昭通红富士苹果槲皮苷和表儿茶素等含量偏高。所测果实指标做正交偏最小二乘判别分析,Q^(2)值0.794,矩阵R^(2)X值0.885,区分参数R^(2)Y值0.874,并建立了正确判别率为93.33%有效OPLS-DA产区识别模型。利用线性判别,筛选得到VC、山梨醇、儿茶素、槲皮素糖苷类、槲皮素鼠李糖苷、槲皮苷、芦丁和槲皮素这8个有效指标,能100%区分各个产区红富士。各产区果实糖积累与产区环境密切相关,总糖和总酸含量与降雨量显著负相关,蔗糖含量与温差呈显著正相关。本研究有望为中国红富士苹果产业发展与地理标志产品保护提供技术支撑。The nutritional quality of Fuji apple candy,acid,and polyphenols varies among production areas in China,so the construction of its origin traceability technology is beneficial to the implementation of production area protection,characteristic product fidelity and sustainable industrial development.Therefore,18 nutritional quality indexes such as total carbohydrate,acid and polyphenols of Fuji apple from six production areas,namely,Aksu in Xinjiang,Jingning in Gansu,Luochuan in Shaanxi,Lingbao in Henan,Yantai in Shandong and Zhaotong in Yunnan were tested and analyzed in this paper.And effective origin traceability nutritional quality indicators were screened based on multivariate statistical analysis to construct a method for the identification of different origins of Fuji apple.The discriminative model for the identification of different production areas of Fuji apple was constructed.The results showed that compared with other production areas,the contents of Aksu Fuji apple total carbohydrate and sorbitol were high,the contents of Jingning Fuji apple total phenols and chlorogenic acid were high and the contents of Lingbao Fuji apple catechin and phloretin were high.The contents of Luochuan Fuji apple fructose and phlorizin were high,the contents of Yantai Fuji apple sugar-acid ratio and rutin were high,the contents of Zhaotong Fuji apple quercitrin and epicatechin were high.The fruit indicators measured were subjected to orthogonal partial least squares discriminant analysis with a Q^(2) value of 0.794,a matrix R^(2)X value of 0.885 and a differentiation parameter R^(2)Y value of 0.874,and a valid OPLS-DA appellation identification model with a correct discrimination rate of 93.33%was established.The linear discriminant was used and eight valid indicators including VC,sorbitol,catechin,quercetin glycoside,quercetin rhamnoside,quercitrin,rutin and quercetin were screened and obtained,which could distinguish 100%of Fuji apple in each appellation.Fruit sugar accumulation in each appellation was closely related to
