摘要：

【目的】探讨低温贮藏过程中游离态和糖苷结合态单萜组分和含量变化趋势,从更加全面的代谢物角度诠释玫瑰香气成分变化规律,为更好地研究贮藏期间葡萄风味品质的变化和最佳贮藏条件的建立提供理论依据。【方法】以两个优新葡萄品种‘瑞都红玫’和‘瑞都早红’为试材,选取健康果实预冷至-1—0℃,放入PE葡萄保鲜膜中,封口入库（（2±1）℃,90% RH）。每15 d取样一次,共取样3次,常规方法测定果实理化指标和外观品质指标;顶空固相微萃取结合气相色谱与质谱联用技术（SPME-GC-MS）测定果实中游离态和糖苷结合态单萜类组分和含量的变化。【结果】低温贮藏过程中,两个品种葡萄果实可溶性固形物含量呈现降低的趋势,可滴定酸含量变化趋势略有不同;失重率、烂果率、落粒率和果梗褐变指数随着低温贮藏时间延长而升高,果柄耐拉力随贮藏时间延长而降低。化合物分析结果显示,里那醇、β-月桂烯、β-cis-罗勒烯、柠檬烯、cis-呋喃型氧化里那醇和香叶醇等是两个葡萄品种的主要游离态单萜成分;而主要糖苷结合态单萜有里那醇、β-月桂烯、香叶醇、香叶醛、β-cis-罗勒烯和橙花醚等。低温贮藏过程中,总游离态单萜含量显著降低,28种游离态单萜的变化趋势聚为4类;相较于贮藏初期,大部分游离态化合物含量呈现降低趋势。主成分分析结果显示香叶酸（M28）、橙花醚（M14）、里那醇（M16）和4-松油烯醇（M17）等游离态单萜可以作为不同贮藏时间样品区分的主要贡献差异单萜成分。各个糖苷结合态单萜在贮藏过程中也表现不同的变化趋势,总结合态单萜含量与游离态单萜呈现相反的趋势。结合态氧化玫瑰是区分两个品种的主要标记物。【结论】‘瑞都红玫’低温耐贮性优于‘瑞都早红’;低温贮藏会引起游离态单萜含量显著降低;游离态香叶酸、橙花醚等化合物可以作为不同时间贮藏样品区分的主要成分;结合态氧化玫瑰可作为品种区分的标记物。

Abstract:

【Objective】The content and composition of free and glycosidically-bound monoterpenes during low temperature storage were investigated, and the changes of aroma components for Muscat flavor from the perspective of more comprehensive metabolites were interpreted, so as to provide a theoretical basis for the better study of the change of grape flavor quality and the establishment of the best storage condition.【Method】Two new grape varieties RuiduHongmei and RuiduZaohong were used as materials. The healthy fruits were precooled to -1 - 0℃ firstly, and then were transferred into PE grape fresh-keeping film. The film was subsequently sealed and put into cold storage ((2±1)℃, 90% RH). The samples were taken every 15 days. The physical, chemical and appearance quality indexes of the fruits were determined by conventional methods. The contents of free and glycosidically-bound monoterpenes in grape berries were determined by headspace solid phase microextraction combined with gas chromatography and mass spectrometry (SPME-GC-MS).【Result】In the process of low temperature storage, the content of soluble solids showed a decreasing trend, while the changes of titratable acid showed slightly different in two grape cultivars; the berry weight loss, percentage of the decayed, berry drop ratio and the browning index were increased with the extension of low temperature storage time, but berry retention force exhibited a decrease; the compounds analysis results showed that the main free monoterpenes in the two grape varieties included linalool, β-Myrcene, β-cis-Ocimene, limonene, cis-furan linalool oxide and geraniol; and the major glycosidically-bound monoterpenes included linalool, β-Myrcene, geraniol, geranial, β-cis-Ocimene, nerol oxide and so on. During low temperature storage, the content of total free monoterpenes decreased significantly; the change patterns of 28 free monoterpenes were grouped into four types; compared to the initial storage stage, the content of most of the free type compounds was decreased sooner or later in the process of storage. Principal component analysis showed that free monoterpenes, such as geranic acid, nerol oxide, linalool and 4-Terpineol (M17) could be used as the major contributions for different storage time samples. Each glycosidically-bound monoterpene also showed different change trends during low temperature storage in two grape cultivars. The content of the total glycosidically-bound monoterpenes showed opposite trends to that of free monoterpenes. The glycosidically-bound rose oxides could be used as marker monoterpenes to distinguish the two grape varieties.【Conclusion】RuiduHongmei had a better low temperature storage characteristics than RuiduZaohong. The contents of free monoterpenes decreased significantly in low temperature storage, the free geranic acid, nerol oxide and linalool could be used as the main components for different storage time, and the bound oxidized rose could be used as the marker for variety differentiation.
