摘要: 为确定不同浓度1-甲基环丙烯(1-MCP)对罗勒保鲜效果的影响,选择四种不同浓度的1-MCP(0、0.5、1.0、1.5 μL/L)处理新鲜罗勒,PE膜包装后置于(4±1)℃低温下贮藏,分析罗勒贮藏过程中失重率、相对电导率、叶绿素含量、乙烯含量、呼吸强度和感官品质的变化,比较不同浓度1-MCP的保鲜效果。结果表明:1.0 μL/L 1-MCP显著(p<0.05)抑制了罗勒的乙烯含量和呼吸强度,显著(p<0.05)延缓了失重率、相对电导率的升高以及叶绿素的损失,比其他三组浓度更有利于保持罗勒采后贮藏期的品质。Abstract: In order to determine the effect of 1-MCP of different concentrations in fresh-keeping of basil, the fresh basil were dealed with 1-MCP of different concentrations(0, 0.5, 1, 1.5 μ L/L), storaging in(4±1)℃ with PE packaging. During the storage, analyzing the changes of weight loss rate, conductivity, chlorophyll content, ethylene content, respiration rate and sensory quality of basil, to compare the effect of 1-MCP of different concentrations. The results showed that:1.0 μL/L 1-MCP inhibited significantly(p<0.05)ethylene content and respiration rate, delaied significantly(p<0.05)the increase of weight loss rate and conductivity, reduced the loss of chlorophyll content of basil.It is more advantageous than the other three groups to maintain the quality of basil during the period of storage.
