摘要
研究低温气调协同乙烯去除剂(EA)、臭氧组合保鲜处理对秋葵贮藏品质的影响。以广西邕宁地区所产的秋葵为原料,分别进行以下处理:低温气调协同1-甲基环丙烯处理(CA+1-MCP处理组),低温气调协同乙烯去除剂、臭氧组合保鲜处理(CA+EA+O3处理组),以低温气调贮藏组作为空白对照(CK组)。对比分析了不同保鲜处理对秋葵贮藏期间失重率、商品率、硬度、叶绿素、可溶性糖、总酚、维C、可溶性蛋白、纤维素等指标的影响。结果表明:与CK组相比,CA+1-MCP处理组、CA+EA+O3处理组均能够对秋葵起到保鲜效果,延缓其采后成熟衰老进程,CA+1-MCP处理组和CA+EA+O3处理组显著提高商品率、降低纤维素含量,有效维持硬度、叶绿素、可溶性糖、总酚、VC、可溶性蛋白含量(P<0.05);与CK组、CA+1-MCP处理组相比,CA+EA+O3处理组能够显著地降低秋葵的失重率,提高商品率,可有效保持硬度、叶绿素及VC含量(P<0.05)。因此,CA+EA+O3处理组对秋葵具有良好的保鲜效果。
The effects of low temperature controlled atmosphere combined with ethylene absorbent and ozone treatment on the storage quality of okra were studied.The okra from Yongning was used as the raw materials,and was treated as follows:controlled atmosphere combined with 1-methylcyclo-propene treatment(CA+1-MCP treatment group),controlled atmosphere combined with ethylene absorbent and ozone treatment(CA+EA+O3 treatment group),and controlled atmosphere storage at low temperature as the blank control group(CK group).The effects of different fresh-keeping treatments on the weight loss rate,commodity rate,hardness,chlorophyll content,soluble sugar content,total phenols content,VC content,soluble protein content,cellulose content in okra during storage were determined.The results showed that:compared with CK,CA+1-MCP and CA+EA+O3 showed function on fresh-keeping of okra and postponed its post-harvest senescence.CA+1-MCP and CA+EA+O3 could significantly improve the commodity rate,reduce the cellulose content,and effectively sustain the hardness,chlorophyll,soluble sugar,total phenols,VC,and soluble protein content(P<0.05).Compared with CK and CA+1-MCP,CA+EA+O3 could significantly reduce the weight loss rate,improve the commodity rate,and effectively sustain the hardness,chlorophyll and VC content(P<0.05).Therefore,low temperature controlled atmosphere combined with ethylene absorbentand and ozone treatment had good fresh-keeping effects on okra.
