Abstract
一种清洗干货红枣的方法，涉及家庭食用和红枣加工领域。传统方法多采用冷水方法，这样往往会达不到理想效果，本方法采用热水清洗红枣，水温在20℃-52℃，浸水时间在12-5分钟，枣在水中会因受热而膨胀，受热膨胀力会使枣皮面积变化，致使枣皮面部分杂质脱落，加之外力搅拌或刷洗同时运作，可以达到彻底清洗目的。还可明显改善食用口感，保持营养成分不流失。
Description
技术领域
一种清洗干货红枣的方法，涉及家庭食用和红枣加工领域。
背景技术
红枣，是鼠李科枣属植物，是原产中国的传统名优特产。民间一直视枣为“铁杆庄稼”“木本粮食”之一。枣作为药用也很早，《本草纲目》中对枣的药用已有记载。常食枣可治疗身体虚弱、神经衰弱、脾胃不和、消化不良、劳伤咳嗽、贫血消瘦，养肝防癌之功能，有“日食三颗枣，百岁不显老”之说。
贮藏红枣，多为鲜枣经风干或脱水制干，而红枣制干后，表皮皱褶内会积存许多灰尘杂质，加之红枣糖分高，有粘性，附着力强。不易清洗干净。学界对于红枣的研究多集中在药用保健和加工方法方面，对于红枣清洗环节却研究甚少。不论居家食用，还是加工领域，不论是人工清洗，还是机械清洗，多采用冷水方法，这样往往会达不到理想效果，本方法采用热水清洗红枣，可有效解决干货红枣清洗不干净的问题，还可明显改善食用口感，保持营养成分不流失。
发明内容
由于红枣在制干过程中，枣本身糖分和生理活性原因，制干前枣皮的碰伤口，除虫口伤外全部都能愈合，在水中浸泡时，红枣是漂浮在水面的，红枣蜡质枣皮，水是渗不进去的，只有枣柄窝是渗水的命门，这样就决定了红枣在清洗时，不能在水中浸泡过长的时间，否则，会使溶解于水的不洁净物有可能会反渗入红枣中，造成清洗环节污染。
本方法采用热水清洗红枣，水温在20℃-52℃，浸水时间在12-5分钟，枣在水中会因受热而膨胀，受热膨胀力会使枣皮面积变化，致使枣皮面部分杂质脱落，加之外力搅拌或刷洗同时运作，可以达到彻底清洗目的。由于红枣受热膨胀过程中，枣体内热气会通过枣柄窝外泄，清洗时间短，不会造成洗水內渗。本方法采用热水必须是饮用水加热到所需合适温度。本方法简单实用，既可以居家应用，也可以应用加工领域，不论是人工清洗，还是机械清洗都可采用。其经验验证方法可以通过掰开枣果，查看枣核与枣肉是否干净分离，食口感是否改善。一般来讲，水温和时间不当，枣核与枣肉粘黏，有浸水感，食口感差。
具体实施方式
一种清洗干货红枣的方法，采用39℃饮用热水，人工用毛刷在水中搅拌清洗干货红枣6分钟，捞出凉干。褶皱内无积存灰尘、杂质，查看枣核与枣肉是干净分离的，清洗后干货红枣皮薄、鲜亮，食口感明显改善，没有浸水感。
