中文摘要: 为研究不同浓度1-甲基环丙烯(1-methylcyclopropene,1-MCP)对枸杞贮藏期间的影响,采用0.2、0.6、1.0 μL/L 1-MCP 处理枸杞并贮藏在(0±1)℃,对“宁杞7 号”的贮藏品质和生理指标进行测定。结果表明,1-MCP 处理均可降低枸杞的呼吸速率和乙烯的释放量,减缓硬度、可溶性固形物和维生素C 含量的下降,维持枸杞良好的色泽、抑制丙二醛含量的增加和相对电导率的上升,在一定程度上维持枸杞原有的风味,而其中0.6 μL/L 1-MCP 处理的枸杞效果最佳。综上,0.6 μL/L 1-MCP 处理的枸杞在低温条件下可以更好地延缓枸杞果实品质的劣变,延长枸杞果实的贮藏期,起到更好的保鲜作用。
Abstract:To explore the effects of different concentrations of 1-methylcyclopropene(1-MCP)on the quality of goji(Lycium barbarum)during storage,goji samples were treated with 0.2,0.6,and 1.0 μL/L 1-MCP and stored at(0 ± 1)℃.The storage quality and physiological indexes of ′Ningqi 7′ were determined.The results showed that 1-MCP treatment could reduce the respiration rate and ethylene release of goji,slow down the decline of fruit firmness,total soluble solids(TSS),and vitamin C content,maintain the good color and luster of goji,suppress the increase of malondialdehyde(MDA)content,and the rise of relative conductivity,and maintain the original flavor of goji to a certain extent.Among them,the effect of 0.6 μL/L 1-MCP treatment on goji was the best.In summary,goji treated with 0.6 μL/L 1-MCP could better delay the deterioration of goji fruit quality under low-temperature conditions,prolong the storage period of goji fruit,and achieve better preservation.
