    摘要:

    通過(guò)不同濃度外源精胺脈沖負(fù)壓滲透處理的方法，研究了外源精胺在保持菜豆貯藏品質(zhì)方面的作用。結(jié)果表明: 在溫度（20±2）℃，相對(duì)濕度80%~85%貯藏條件下，經(jīng)不同濃度(0、0.02、0.2、0.5、1.0mmol/L) 的外源精胺真空滲透處理后的菜豆，其貯藏品質(zhì)均得到不同程度的保持。外源精胺不同處理可有效延緩菜豆腐爛和銹斑的發(fā)生，而且可以抑制菜豆失重率和豆莢切割力的增加，并使菜豆豆莢的可溶性固形物以及菜豆豆粒硬度和可溶性蛋白含量得以保持。不同濃度外源精胺處理效果比較表明，0.5mmol/L精胺處理保持菜豆貯藏品質(zhì)的效果最好，貯藏至第8天菜豆腐爛指數(shù)和銹斑指數(shù)分別比對(duì)照低68%和23%。

    Abstract:

    With the aim to investigate the influence of spermine (SPM) treatment by vacuum pulse infiltration on postharvest quality of common beans (Phaseolus vulgaris L.), common beans were immersed in SPM solutions (0, 0.02, 0.2, 0.5 or 1.0mmol/L) under vacuum (-20kPa) for 2min and then stored at 20℃, 80%~85% relative humidity for 8 days. The results indicated that exogenous SPM treatments could significantly inhibit water loss and cutting-force increasing, and reduce the rust spots forming and decay of bean pod. Exogenous SPM treatments could also remarkably prevent decrease in levels of the soluble protein in the bean seed and the total soluble solids in the bean pod. The treatment with 0.5mmol/L SPM was more effective than the other treatments. The decay or rust spots index of the bean pod treated with 0.5mmol/L SPM was about 68% or 23% lower than that of control in the 8th day of storage, respectively. The results could be applicable to improve quality of common bean for commercial purpose. 
