摘　　要：【目的】研究脐橙采后免发汗式商品化处理及贮藏保鲜技术,为脐橙产业健康发展提供技术支撑。【方法】以适时采摘的脐橙为原料,在前期自主研发的脐橙免发汗式中温预处理技术基础上,通过单因素和正交试验,探讨不同防腐保鲜液配比、喷蜡条件、包装材料及贮藏方式对脐橙保鲜效果的影响,确定脐橙采后免发汗式商品化贮藏保鲜最佳工艺技术。【结果】防腐保鲜液配比、喷蜡条件、包装材料及贮藏方式对脐橙保鲜效果均有较大影响,脐橙采后免发汗式商品化贮藏保鲜的最佳工艺技术为:采后脐橙经清洗消毒,用40%百可得1000倍和22.2%戴挫霉500倍的防腐保鲜液于35℃恒温浸泡,风干后用浓度1∶4的40℃果蜡进行喷蜡处理,蜡液干燥30 s后薄膜袋单果包装放入杂木箱,置于负压强排式通风控温库贮藏,在此保鲜条件下,脐橙果实贮藏至150 d,好果率达95.40%,果实品质仍保持较好。【结论】采后免发汗式商品化贮藏保鲜技术(防腐保鲜液浸果+喷蜡+薄膜袋单果包装+装入杂木箱+负压强排式通风控温库贮藏)可有效提高采后脐橙好果率,保持果实品质。[Objective]The techniques of commercialized storage and fresh-keeping by avoiding sweat for post-harvest navel orange were studied to provide technical support for the healthy development of navel orange industry. [ Method ]On the basis of previous independent research and development of sweat-avoiding pretreatment techniques with medium temperature for post-harvest navel orange, timely harvested navel oranges were used as raw materials. Singlefactor and orthogonal experiments were conducted to investigate the effects of different compound ratios of antistaling a- gent, waxing conditions, packaging materials and storage methods on preservation of navel orange, following which the optimized procedure and technique of commercialized processing, storage and preservation for post-harvest navel orange were obtained. [Result]Compound ratios of antistaling agent, waxing conditions, packaging materials and storage methods had great influence on preserving effects of navel orange. The optimized procedure and technique of commercialized storage and preservation for post-harvest navel orange was as follows. Clean and disinfect post-harvest navel oranges, soaking at a constant temperature of 35 ℃ in antisepsis and fresh-keeping liquid with 40% Bellkute （ratio of 1000 times） and 22.2% Imazalil （500 times）, and were then treated by fruit wax （concentration of 1：4 and temperature of 40 ℃ ）. After air-drying, single fruit was put into film bags 30 s after the wax was dry and the fruits were packed with miscellaneous wooden boxes, and at last, they were placed in a negative-pressure storeroom with strong-exhausting ventilation exhaust and controlled temperature for storage. Under the above preservation condition, orange fruits were preserved for 150 days, with a good fruit rate of 95.40%, and fruit quality remained good. [Conclusion] Utilizing techniques of commercialized storage and fresh-keeping by avoiding sweat for post-harvest navel orange （soaking fruits in antisepsis and fresh- keeping liquid＋spraying
