摘要:
为了探明乙烯与桃果实冷害之间的关系,以‘八月脆’桃果实为试验材料,研究了乙烯吸收剂、1—MCP、外源乙烯对低温MA 贮藏期间和货架期桃果实的主要风味物质含量的影响。结果表明:外源乙烯处理能使桃果实贮藏前期保持很好的风味,但后期风味最差。低温MA 贮藏期间和货架期期间1—MCP 处理与乙烯吸收剂处理类似,贮藏后期还能保持较好的桃风味,且1—MCP 处理效果更好。低温MA 贮藏期间,己醛、苯甲醛含量受低温抑制明显,未随乙烯存在与否而明显变化;反—2—己烯醛随外源乙烯有无而变化,芳樟醇、γ—癸内酯含量和脂氧合酶(LO X)活性因乙烯存在而降低或后期降低,这些物质变化可以作为评价桃果实冷害的指标。
