【摘要】 本文研究了不同极值气体条件下贮藏过程中,葡萄果实中乙醇和乙醛含量的变化及二者与葡萄气体伤害的关系。结果表明,玫瑰香葡萄气调贮藏CO2伤害极值为10%O2+18%CO2条件下100d,10%O2+15%CO2条件下120d;低O2伤害症状不明显。低O2 与高CO2能明显引起葡萄浆果中乙醇和乙醛含量的升高,乙醛是引起葡萄气体伤害的主要原因。更多还原

【Abstract】 The concentration of ethanol and acetaldehyde in MeiGuiXiang (fragrant rose scent) grape after 120 days storagewas studied .It showed that CO2 injury of grape happened in 10%O2+18%CO2 after 100 days storage, 10%O2+15%CO2after 120 days storage, while low O2 injury during storage was not apparent. Low O2 and high CO2 caused the obviousincrease of ethanol and acetaldehyde in grape during storage. Acetaldehyde was the main factor causing the gas injury ofgrape.更多还原
