产地、年份、品种对葡萄干矿物元素含量的影响

Effects of geographical origin,storage time,and variety on the content of mineral elements in raisin

该研究采集了中国新疆吐鲁番、哈密以及和田3个不同产地、3个年份、2个不同品种共54份葡萄干样品,并测定其中50种矿物元素含量,采用多因素方差分析,研究了产地、年份、品种及其交互作用对样品中矿物元素含量的影响。结果表明,产地因素对葡萄干中矿物元素含量影响最大,葡萄干中Li、Sc、V、Co、Y、Mo、Ba、La、Ce、Ti、Mn、Cu、Al、Ca、Fe、Mg元素含量主要受产地影响,Ni、Rb、Na元素含量主要受年份影响,Sr、Cs、Zn元素含量主要受品种影响。筛选出与产地有关的矿物元素,可以为地理标志葡萄干产地鉴别与保护的研究提供参考。

The aim of this study was to analyze the effects of geographical origin,storage time,and variety on mineral contents in raisin in order to lay a foundation for screening effective indicators of raisin origin traceability.50 kinds of mineral elements content in 54 raisin samples from Turpan,Kumul,and Kotan,of Xinjiang China were investigated.The effects of geographical origin,year,variety,and their interaction on mineral element content were also studied by multiway ANOVA.The results showed that geographical origin had the greatest interaction on mineral contents in raisin,followed by year and variety.The contents of Li,Sc,V,Cr,Co,Y,Mo,Ba,La,Ce,Ti,Mn,Cu,Al,Ca,Fe,and Mg mainly depended on geographical origin.Those Ni,Rb,and Na were closely related to the year.While Sr,Cs,and Zn were mainly influenced by variety.The selected mineral elements related to the origin of raisin provide a reference for the research on the identification and protection of the origin of raisin.
