1MCP处理对鲜切鼠尾草品质的影响

研究1-MCP处理对鲜切鼠尾草品质的影响。结果显示使用浓度为1 mg/dm³的1-MCP处理24 h,可以有效维持鲜切鼠尾草中叶绿素含量,降低叶片表面变黄程度和出现小黑点的几率。GC-MS分析显示新鲜鼠尾草中检出19种挥发性物质,含量合计233.2μg/g,其中α-蒎烯、2-莰酮、樟脑萜、桉树醇、β-蒎烯和β-侧柏酮是鼠尾草挥发性物质的主要成分;1-MCP处理后检出21种物质,含量合计382.3μg/g,与新鲜鼠尾草的风味最相似。因此,1-MCP处理提高了鲜切鼠尾草的品质。 

Effect of 1- MCP treatment on quality of fresh- cut sage

The effect of 1- MCP treatment on quality of fresh- cut sage was evaluated. The 1- MCP treatment of1 mg / dm³ for 24 h hold the chlorophyll content effectively,and avoided the browning and formation of the black spots on the surface of the sage leaves. The GC- MS analysis showed that total 19 volatile compounds were detected in the fresh sage that was 233.2 μg / g. The α- pinene,2- camphor,camphene,cineole,β- pinene andβ- thujone were the main components of the fresh sage.The sage after the 1- MCP treatment presented 21 volatile compounds,which was 382.3 μg / g.Remarkably,the flavor of the 1- MCP treated fresh- cut sage was similar to that of the fresh sage.Hence,the 1- MCP treatment enhanced the quality of the fresh- cut sage.
