Description
技术领域
本发明涉及农产品保藏技术,尤其涉及一种水果保鲜存储方法,属于农林作物存储技术领域。
背景技术
夏季是很多水果成熟采收的季节。然而,正逢酷暑时节,短时间内采收后水果时常发生病害,极易发霉、腐烂败坏,保护、贮藏和运输极为困难,采后损耗严重,很大程度上降低了贮藏水果的食用品质、经济价值和卫生安全性。同时,如果短期内大量水果涌入市场,往往导致其价格大幅下跌,冲击本地市场。
近年来,随着人们对食品新鲜度、食用安全性等要求的提高和销售方式的多样性,特别是近几年来“互联网+”在果蔬销售行业的快速发展,安全高效的保鲜储运技术已成为促进水果产业化发展的关键因素,水果的贮运保鲜一直是人们的关心热点。
发明内容
本发明提供一种新的水果保鲜存储方法,通过合理的控制水果表层的细菌和水果温度,以解决现有技术中水果保存时间短的技术问题。
本发明实施例的水果保鲜存储方法,包括如下步骤:
步骤一;将水果采摘后,迅速浸润至盐水中浸泡15~25分钟,盐水浓度为15%-23%,浸泡完成后迅速冷风风干;
步骤二;将吹干的水果采用紫外线照射10~15分钟,照射5分钟以后表面采用超声波雾化器喷射雾化乳液,该雾化乳液中含有质量分数2%甲壳素、2.5%的饱和脂肪酸;
步骤三;将水果放入密封袋,并在密封袋内充入混合气体,该混合气体包含体积分数5%~10%的氧气、浓度10%~15%的二氧化碳、余量为氮气;
步骤四;密封后放入冷库保存,温度保持在-1~2℃,湿度85%~95%。
如上所述的水果保鲜存储方法,其中,所述步骤一中,所述盐水的温度低于所述水果表面温度6~12℃。
如上所述的水果保鲜存储方法,其中,所述步骤一中,所述盐水浸泡的过程中,采用超声波换能器对水果表面进行间歇性的清洗;超声波换能器的功率为800W/立方米;清洗时间为开启10~15秒,间隔10~15秒。
如上所述的水果保鲜存储方法,其中,所述步骤三中,所述密封袋为透气材料制成,该密封袋的透氧率为14400~24000(mL/24h·m2·101kPa)。
如上所述的水果保鲜存储方法,其中,所述步骤一中,所述盐水的浓度为19%,浸泡时间为18分钟;所述盐水中还添加有质量分数4.8%的聚乙烯醇。
如上所述的水果保鲜存储方法,其中,所述步骤四中,水果表面温度控制在每6小时降低4~8℃。
本发明实施例中,采用以上工艺方法能够有效延长水果的存储时间,可保鲜90天以上,且能够保持水果的风味和水分不会散失,大幅度延长了货架期。
