中文摘要: 为有效保持脆李货架期内的品质,以巫山脆李为试验材料,研究电商速递过程中1-甲基环丙烯(1-methylcyclopropene,1-MCP)处理对脆李果实在4 ℃贮藏货架期内营养成分、生理代谢的影响效果和规律。结果表明,电商速递中1-MCP 保鲜剂的使用可有效降低货架期内脆李果实呼吸强度、乙烯释放速率,延缓果实C*值和L*值的下降,抑制叶绿素含量、抗坏血酸(ascorbic acid,VC)含量的下降,保持较高的果实硬度及可滴定酸(titritable acidity,TA)含量,减少果实质量损失,抑制丙二醛(malondialdehyde,MDA)的积累。电商速递中使用1-MCP 处理可有效延缓巫山脆李客户端货架期内的后熟衰老,有效保持果实货架品质。
Abstract:This study aims to improve the quality of crisp plums during the shelf life.To be specific,the effect of 1-methylcyclopropene (1-MCP)treatment in E-commerce logistics on the nutrient composition and physiological metabolism of Wushan crisp plums during shelf life at 4 ℃was investigated.The results showed that 1-MCP treatment remarkably reduced the respiratory intensity and ethylene release rate,delayed the decline of C*and L*,inhibited the decrease of chlorophyll content and ascorbic acid (VC)content,maintained hardness and titratable acid(TA)content,decreased mass loss,and suppressed malondialdehyde(MDA)accumulation of the plums during shelf life.Thus,the application of 1-MCP in E-commerce logistics can delay the ripening and senescence and ensure the quality of crisp plums during shelf life.
