摘要:

以新鲜大台农芒果为原料,利用壳聚糖和1-MCP 对其采后采取不同贮藏处理方式,对货架期间芒果的失重率、硬度、可溶性固形物、呼吸强度、可滴定酸和叶绿素含量的变化进行研究。结果表明:经1-MCP 和壳聚糖复合处理的芒果在第10 天达到呼吸高峰,呼吸高峰与CK 相比推迟4d,且可滴定酸含量为CK 的4.4 倍:同时壳聚糖和1-MCP 还能显著降低芒果的软化程度,有效降低芒果的失重率和叶绿素的损失,推迟可溶性固形物含量上升,有效延缓芒果的后熟过程;壳聚糖和1-MCP 复合处理比两者各自的处理效果都好,能进一步显著地改善芒果在货架期的品质表现,为芒果综合贮藏保鲜技术开发提供依据。

Abstract:

Fresh Datainong mango was treated with chitosan and 1-methylcyclopropene (1-MCP) during storage. The weight loss rate, hardness, soluble solid content, respiration rate, titratable acid content and chlorophyll content of mango during shelfstorage period were explored. Results indicated that the combinatorial treatment of chitosan and 1-MCP exhibited the highest respiration peak on the 10th day. Compared with CK, there was a delay for 4 days, and the content of titratable acids exhibited an increase of 4.4 folds. Chitosan and 1-MCP could also significantly reduce the softening degree of mango, decrease weight loss rate and chlorophyll content, attenuate the increase of soluble solids and maturity. Combinatorial treatments of chitosan and 1-MCP exhibited a better effect than chitosan or 1-MCP treatment alone, which will provide a significant improvement of mango quality during shelf-storage period.
