The influence of different-concentrations 1-MCP on storing white celery

摘要

The changes in white celery under different concentrations of 1-MCP (0 μl/, 0.1 μl/L, 1 μl/L and 5 μ1/L) were analyzed to present the most suitable concentrations of 1-MCP to maintain a good texture and storage quality, through measuring the determination of the maximum shear, moisture content, chlorophyll content and respiration rate. The key factor with the texture was also analyzed, showing that 0.1-μl/L 1-MCP can suppress the increase of the respiration rate and maintain high moisture, but it did not present a good texture. 1 -μ1/L and 5-μl/L 1 -MCP can maintain a good texture, but 5-μl/L 1-MCP made white celery rot more easily and presented the increase of the respiration rate and low moisture. 1-ul/L was the optimum using concentration for 1 -MCP on storing white celery.
