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
