外源精胺处理对采后黄瓜品质的影响

Effect of Exogenous Spermine Treatment on Quality of Postharvest Cucumber

摘要: 使用浓度为1 mmol/L的精胺处理黄瓜10 min,于常温(20±1)℃下贮藏,通过对贮藏期间各项品质指标的测定,探究精胺处理对黄瓜采后品质的影响。结果表明:外源精胺处理可以有效地保持黄瓜的外观品质,抑制失重率的上升及硬度的下降,延缓叶绿素降解、维生素C的流失及可溶性固形物含量的降低,说明1 mmol/L的精胺处理可有效的保持黄瓜的贮藏品质。结论:1 mmol/L的精胺处理可有效的保持黄瓜的贮藏品质。

Abstract: In order to study the effect of spermine treatment on the quality of postharvest cucumber,the cucumber was treated with 1 mmol/L spermine solution for 10 min,then stored at(20±1)℃.The results showed that exogenous spermine treatment could effectively maintained the sensory quality of cucumber,inhibited the decline of hardness and the increase of weight loss,reduced the decrease of chlorophyll,V_C and soluble solids content,and achieved better storage effect. Conclusion:1 mmol/L spermine treatment could effectively maintain the storage quality of cucumber.
