气调贮藏不同气体比例对哈密瓜86-1贮期品质及生理活性的影响

[目的]筛选适宜的哈密瓜86-1贮藏保鲜条件.[方法]在3 ℃贮藏条件下,设置O_2+CO_2:3;+0;;O_2+CO_2:4;+1;;O_2+CO_2:5;+2;三种气体条件,研究不同贮藏气体条件对86-1采后呼吸强度、乙烯释放量、可溶性固形物含量、总糖含量、总酸含量、硬度、果肉细胞膜透性等生理指标的影响.[结果]在3℃的贮藏温度下,各气调处理并没有起到抑制果实呼吸强度、减少其乙烯释放量等作用.与冷藏相比,气调处理的果实糖酸等营养物质的消耗略低,对其品质及风味保持较好.[结论]相对而言,CO_2含量较高的气体环境更利于瓜的贮藏,CO_2/O_2=2/5明显优于CO_2/O_2=0/3,究其原因还需进一步研究验证.

Effect of Different Air Condition on the Quality and Physiological Activity of Postharvest 86-1 Melon During Storage

[Objective and Method]The three kinds of storage air condition:O_2+CO_2:3%+0%;O_2+CO_2:4%+1%;O_2+CO_2:5%+2% were designed to study the effect of the different air condition on the respiration rate,ethylene production,soluble solids content,total sugar content,total acid content,hardness,pulp cell membrane permeability, etc of the 86-1 melon during storage for choosing a better storage condition. [Result]The results showed that under 3 ℃,different air condition can not control the 86-1 melon's respiration rate and reduce the ethylene production .Different air condition can keep the 86-1 melon's better flavour and total sugar,acid content. [conclusion]More CO_2 content will be better for the 86-1 melon's storage, such as CO_2/O_2=2/5 was better than CO_2/O_2=0/3,whose reason should be further discussed in the future.
