摘要: 以四季豆为试材,采用气调贮藏(气体组成:5% O2+1% CO2 +94% N2;温度:9.0℃±0.5℃)和冷藏(气体组成:空气;温度:9.0℃±0.5℃)两种保鲜方式,研究气调处理(CA)对贮藏期四季豆生理生化特性的影响。结果表明:气调贮藏的四季豆有较好的品质——还原糖和叶绿素含量较高,而纤维素积累较少。气调有利于保持较高的过氧化物酶(POD)、超氧化物歧化酶(SOD)、过氧化氢酶(CAT)和纤维素酶(CE)活力;同时气调可以有效减少超氧阴离自由基(O2-·)、过氧化氢(H2O2)和丙二醛(MDA)等有害物质积累。气调有利于四季豆贮藏期的品质保持,延长贮藏时间。

Abstract: To explore the effect of controlled atmosphere (CA) on physio-biochemical index of Phaseolus vulgaris L., two different storage conditions such as controlled atmosphere storage (gas components: 3% O2 + 1% CO2 + 6% N2; temperature: (9.0 ± 0.5) ℃) and cold storage as a control (gas components: air; temperature: (9.0 ± 0.5) ℃) were used. The results showed that Phaseolus vulgaris L. stored in CA revealed better quality with the characteristics of higher reducing sugar content, higher chlorophyll content and less cellulose content during the storage period. Meanwhile, the higher activities of peroxidase (POD), catalase (CAT), superoxide dismutase (SOD) and cellulose enzyme (CE) were observed in Phaseolus vulgaris L. stored in CA; in contrast, lower accumulation of superoxide anion (O2-·), hydrogen peroxide (H2O2) and malondialdehyde (MDA) was detected. Therefore, CA can maintain the quality of Phaseolus vulgaris L. during storage, and prolong its storage time.

Key words: Phaseolus vulgaris L., controlled atmosphere, quality, physio-biochemistry
