摘　　要：以陕北干红枣为材料,对比碱液直接浸泡和复水后碱液浸泡两种去皮方法,研究干红枣去皮工艺的最佳条件。结果表明,干红枣复水后再用氢氧化钠溶液浸泡去皮效果较佳。通过单因素试验和正交试验,以红枣感官评价为标准,得出了最优工艺组合为浸泡时间3.5min,浸泡温度60℃,氢氧化钠溶液浓度5.5%。Used the dry red dates of north of Shannxi province as materials, the optimal peeling conditions was studied by direct and indirect alkali liquor soaking. The result indicated that NaOH solution soaking after rewatered was better than the direct way. By single factor test and orthogonal experiment, the optimal process combination was 3.5min, the temperature was 60℃, and NaOH solution concentration was 5.5%.
