摘要:

以甘肃天水‘花牛’苹果为原料,通过测定其果实硬度、VC含量、有机酸质量分数、可溶固形物质量分数及腐烂率等指标,研究低温贮藏及1-甲基环丙烯(1-methylcyclopropene,1-MCP)处理对‘花牛’苹果果实品质与生理变化的影响。结果表明:低温处理的保鲜作用优于1-MCP处理;低温及1-MCP处理均能显著减缓果实硬度及VC含量下降,降低腐烂率,能较好地维持外观色泽与口感,并在一定程度上稳定了有机酸质量分数变化,但对可溶固形物质量分数的影响极小。

Abstract:

The effects of low temperature and 1-MCP treatment on the quality and physiological change of ‘Huaniu’ apple
(from Tianshui, Gansu province) during storage were comparatively evaluated with respect to fruit hardness, vitamin C
content, titratable acid content and soluble solid content. The results showed that low temperature was better than 1-MCP
treatment for ‘Huaniu’ apple during storage. Both treatments could obviously inhibit fruit softening, the decrease in vitamin C
content and the incidence of fruit decay, maintain the good appearance and taste, and stabilize titratable acids. However,
there was little influence on the soluble solid content in the fruit.
