摘　　要：本试验以环氧乙烷高级脂肪醇(Oxyethyene Higher Aliphatic Alcohol,OHAA)和肉桂精油为保鲜材料,在温度为0±2℃、相对湿度为85%～90%的贮藏条件下,研究OHAA和不同浓度的肉桂精油(0.16%,0.20%,0.24%)对冬枣的贮藏保鲜效果。结果表明:经过80天的贮藏,OHAA肉桂复合保鲜剂对冬枣的贮藏保鲜有良好效果。其中1%OHAA与0.16%肉桂精油复合保鲜剂的保鲜效果最好。其果实腐烂率最低,仅为29.96%;硬度为6.49 kg/cm2,则果实贮运性能好;果实内部生理环境状态良好,过氧化氢酶(CAT)活性0.371 mgH2O2/g.min;果实营养成分损失较少,其果实Vc、可溶性固形物分别为143.28mg/100g、24.3%;而空白对照处理冬枣果实腐烂率在贮藏66天时就高达32%,营养成分损失严重,Vc含量仅有112.54 mg/100g。说明1.0%OHAA复合0.16%肉桂精油保鲜剂涂膜处理冬枣可延缓果实衰老,明显延长其贮藏期。OHAA （Oxyethyene higher aliphatic alcohol） and cinnamon oil as fresh -keeping material were used to detect the fresh - keeping effects on winter jujube processed by 1% OHAA combined with different concentrations of cinnamon oil （0. 16%, 0. 20%, 0. 24% ） at the temperature of 0 -2 ℃, relative humidity 85% -90%. The results showed that after 80 days, compound OHAA cinnamon preservatives had better effects on the storage and preservation of winter jujube, and the combination of 1% OHAA and 0. 16% cinnamon oil was the best, with lowest fruit decay rate, by 29. 96% ; 6. 49kg/cm^2, fruit hardness, good fruit storage and transportation properties and good internal environmental physiological state. The activity of CAT （eatalase） was 0. 371mgH202/g. m. The fruit nutrition loss was less and the contents of Vc, soluble solids in fruit were 143. 28 mg/100g and 24. 3% respectively; while the fruit decay rate in the blank control group reached 32% at the 66th day of storage, severe loss of nutrients occurred, and the content of Vc was only 112. 54 mg/100g. This indicated that the compound preservative with 1. 0% OHAA and 0. 16% cinnamon oil used on winter jujube fresh - keeping could delay the fruit senescence, significantly prolong the storage period.
