摘要:

为探讨1-甲基环丙烯(1-methylcyclopropene,1-MCP)对采后红椒质地的影响,以“洛椒118”淮安红椒为材料,采用质构仪质地多面分析方法、压缩测试结合相关性分析法和主成分分析法对红椒质地特性进行分析。结果表明:不同剂量1-MCP处理均能较好地延缓采后红椒按压力的下降,其中0.5、1.0 mL/L 1-MCP处理的作用更明显;另外,1-MCP处理可较好地保持红椒硬度、黏着性、咀嚼性、回复性等质构性能,结合主成分分析的结果,1.0 mL/L 1-MCP处理对红椒的保鲜效果较佳。

Abstract:

The present study aimed to explore the effect of 1-methylcyclopropene (1-MCP) treatment on the texture
properties of red chili peppers during post-harvest storage. Changes in texture parameters of ‘Luojiao 118’ red chili pepper
from Huai’an, Jiangsu province were studied by using texture analyzer through texture profile analysis and compression test
and analyzed by correlation analysis and principal component analysis (PCA). The results indicated that 1-MCP treatments
at all investigated doses especially at 0.5 and 1.0 mL/L retarded the decrease in compression resistance during postharvest
storage of red chili peppers. In addition, 1-MCP treatments provided better maintenance of hardness, adhesiveness,
chewiness, resilience and other texture parameters. Further PCA analysis suggested that 1.0 mL/L 1-MCP treatment provided
optimum quality preservation of red chili peppers.

Key words: red chili pepper, 1-methylcyclopropene, preservation, texture profile analysis
