摘要

以恭城月柿为试材,采用精准相温(-0.5±0.3)℃结合不同浓度(0(CK)、1、3、5μL/L)1-甲基环丙烯(1-MCP)的处理方式,探索1-MCP最佳处理浓度及对柿果保鲜效果的影响。结果表明,不同浓度1-MCP处理均可保持柿果的感官品质、色泽及抗坏血酸(VC)含量,降低乙烯呼吸速率和丙二醛含量,从而达到延长贮藏期和维持柿果品质的目的,且随着贮藏时间的延长,保鲜效果更加显著,但是对可滴定酸(TA)含量及呼吸强度并无显著影响。灰色关联分析可知,4个处理的关联度分别为0.566、0.885、0.654、0.722,按大小排序为1μL/L 1-MCP>5μL/L 1-MCP>3μL/L 1-MCP>CK,说明采用浓度为1μL/L 1-MCP处理柿果能够具有最佳贮藏效果,5μL/L 1-MCP次之,3μL/L 1-MCP效果较差。
        Taking Gongcheng Yue persimmon as test material, the optimal treatment concentration of 1-methylcyclopropene(1-MCP) and the effect on persimmon fruit preservation was studied by using precise phase temperature(0±0.5) ℃ combined with different concentrations of 1-MCP treatment. The results showed that, different concentrations of 1-MCP treatment could significantly maintain sensory quality, color and VC content of persimmon fruit, and reduce the ethylene respiration rate and malondialdehyde content, so as to prolong the storage period and maintain the quality of persimmon fruit. And the preservation effect enhanced with the prolongation of storage time, but the treatment had no significant effect on titratable acid(TA) and respiratory intensity. According to the grey correlation analysis, the correlation degree of the four treatments was 0.566, 0.885, 0.654, and 0.722, respectively, and the order of size was 1 μL/L 1-MCP>5 μL/L 1-MCP>3 μL/L 1-MCP>CK, which indicated that the persimmon fruit treated with1 μL/L1-MCP had the best storage effect, followed by 5 μL/L 1-MCP, and the effect of 3 μL/L 1-MCP was the worst.
