摘  要:
以黄秋葵荚果为试材,研究9℃恒温条件下1-MCP对秋葵荚果叶绿素、氨基酸、可溶性固形物、硬度和外观变化的影响。结果表明:在贮藏的前2d,1-MCP处理不能抑制叶绿素含量的下降,但2d后,1-MCP处理均可延缓叶绿素含量的降低。1-MCP处理组氨基酸含量下降比较缓慢,其中200nL/L处理组氨基酸含量下降最慢。对照组与1-MCP处理组的可溶性固形物含量均呈先上升后下降的趋势,其中200nL/L处理组能更好地抑制可溶性固形物含量的下降。同时,1-MCP处理可抑制果实硬度下降,更好地保持秋葵荚果的贮藏品质。

摘  要:
This study was designed to examine the effect of 1-methylcyclo-propene(1-MCP) treatment on the contents of chlorophyll,amino acids and soluble solids,hardness and appearance of okra pods stored at 9 ℃.1-MCP treatment did not delay the decrease of chlorophyll content during the first 2 days of storage rather than during the following 3 days.Total amino acid content in 1-MCP treated okra pods declined slowly,and the slowest decline was observed in okra pods treated with 200 nL/L 1-MCP.Soluble solid content initially rose and then declined in 200 nL/L 1-MCP treatment group and control group.Compared with control group,200 nL/L 1-MCP treatment could effectively inhibit the reduction of soluble solids.Moreover,1-MCP treatment was effective in inhibiting the decline of fruit harness so that storage quality of okra pods could be maintained better.
