摘　　要：以环氧乙烷高级脂肪醇(Oxyethyene higher aliphatic alcohol,简称OHAA)为保鲜材料,在(0±1)℃、80%～90%的相对湿度下,研究不同质量分数OHAA(分别为0.5%、1.0%、1.5%)对新疆阿克苏地区小白杏[经1.0 mg/L 1-甲基环丙烯(1-MCP)熏蒸12 h]的贮藏保鲜效果。经过42 d的贮藏,试验结果表明:以质量分数为1.0%的OHAA涂膜处理效果较好,其果实腐烂率最低,仅为10%;果实贮运性能好,硬度为8.67 N/cm2;果实营养成分损失较少,其果实Vc、可溶性固形物、可滴定酸分别为7.8 mg/g、13.83%、0.83%;而空白对照处理小白杏实腐烂率高达50%,营养成分损失严重,Vc、可滴定酸含量仅有5.5 mg/g和0.62%。相对于其他处理,1.0%的OHAA涂膜处理小白杏可延缓果实衰老,延长贮藏期。The test uses OHAA （abbreviation of oxyethyene higher aliphatic alcohol） as the fresh-keeping material. It discusses the influence of different conditions on the preservation of apricot [after being suffocated for 12 h with 1.0 mg/L 1-MCP（abbreviation of 1-Methyl-Cyclopropene）] under such conditions of temperature（0±1） %, relative humidity（80%-90%） and the experimental concentration of OHAA（0.5%, 1.0%, 1.5%）for about 42 days＇ test of storage. The experimental results show： The effect of the 1.0% OHAA coating is the most distinguished. The decay rate of the fruit is the lowest, which is 10%. The capacity of fruit storage is better and its hardness is 8.67 N/cm2. The loss of nutrition is extremely low,in which the content of Vitamin C is 7.8 mg/g, the content of soluble solid is 13.83% and the content of titrating acids is 0.83%. In comparison, the decay rate of the fruit in the selected control group has reached 50%, in which the loss of the nutrition is extremely serious, the content of Vitamin C is only 5.5 mg/g and the content of titrating acid is 0.62%. Such experimental results indicate that using 1.0% OHAA in coating preservation can obviously stave the caducity of apricot and can effectively last its storage period.
