摘要: 苹果含有多种功能性酚类物质,但对其采后货架期间的变化规律尚无系统研究。本实验以‘乔纳金’苹果 为材料,研究1-甲基环丙烯(1-methylcyclopropene,1-MCP)处理后贮藏3 个月,货架时间和温度对果皮和果肉中 5 种单体酚含量的影响。结果表明:‘乔纳金’苹果果皮中金丝桃苷含量最高,果肉中绿原酸含量最高,随着货架时 间的延长,‘乔纳金’果实中金丝桃苷、绿原酸、槲皮素、芸香叶苷及总酚含量均呈现下降趋势,而根皮苷含量呈上 升趋势。1-MCP有效地延缓了贮藏期和货架期果皮、果肉中金丝桃苷、总酚含量的下降和根皮苷含量的上升。

Abstract: Apple contains a variety of functional phenolic substances, but no systematic studies have been conducted to investigate their variation during shelf life after harvest. In this paper, ‘Jonagold’ apples were treated with 1-methylcyclopropene (1-MCP) and then stored at (0 ± 1) ℃ for 3 months with the aim of investigating the effect of 1-MCP treatment on the contents of 5 individual phenolic compounds in apple flesh and peel. The results obtained were as follows. The most abundant phenolic compound in the peel was hyperoside, whereas chlorogenic acid was the most abundant phenolic compound in the flesh. During the shelf period, the contents of hyperoside, chlorogenic acid, quercetin, rutin and total phenolics decreased in the fruits, while the level of phloridzin increased. 1-MCP treatment effectively maintained the contents of hyperoside, chlorogenic acid, quercetin, rutin and total phenolics, and inhibited the increase in phloridzin.
