Description
本发明属于水果或蔬菜保存的技术领域,特别是涉及用保护层涂覆水果或蔬菜的方法。
水果和蔬菜是人类生活不可缺少的重要物质。但蔬菜水果采收后,极易腐烂和失水,不耐贮存和运输,严重影响其商品价值,经济损失高达20-50%。人们对此进行了大量研究和探索,提出了一些果蔬保鲜剂。但现有的果蔬保鲜剂价格较高,效果却不理想。有的果蔬保鲜剂对人体会产生不良作用并污染环境;有的使用后会在果蔬的表面形成一些药物的斑点,既不美观又影响食用。这是一个至今尚未解决的技术难题。
本发明的目的在于避免上述现有技术中的不足之处而提供一种以天然生物资源为原料,以高分子半透性生物膜为基质,对人畜无害,不污染环境的果蔬保鲜剂及其生产方法。
本发明的目的可以通过以下技术措施来实现:
本发明的果蔬保鲜剂主要组成为(用量为重量份):
松香300-500 虫胶100-300 蜂蜡300-500
噻菌灵5-10(或者山梨酸钾或苯甲酸钠1-10)
制备本发明果蔬保鲜剂主要成分优选重量配比范围是:(用量为重量份):
松香250-350 虫胶150-250 蜂蜡450-500
噻菌灵6-8(或者山梨酸钾或苯甲酸钠4-7)
本发明果蔬保鲜剂主要成分的最佳重量配比是:
松香300 虫胶200 蜂蜡500
噻菌灵7(或者山梨酸钾或苯甲酸钠6)
将上述各组份制成本发明果蔬保鲜剂的生产方法是:
①按松香∶虫胶∶乙醇=15∶10∶100的重量配比,将松香和虫胶溶于乙醇溶液;
②将蜂蜡进行匀化或者按蜂蜡∶皂化剂=100∶1的重量配比,用常规方法对蜂蜡进行皂化;
③将①和②经乳化混合后制成生物膜基质;
④在③中添加噻菌灵或山梨酸钾或苯甲酸钠并搅拌均匀即可。
本发明的用量及使用方法:
①将本发明的保鲜剂1升加水50-100升制成稀释剂,可处理水果4-6吨或蔬菜2-3吨;
②本发明适用于多种水果和蔬菜,将蔬菜或水果在稀释液中浸渍1-2分钟后,取出晾干;
③装箱后可在常温下贮存或运输,低温条件下效果更好。
本发明的果蔬保鲜剂实际应用的结果表明,具有以下突出优点:原料来源丰富易得,制法简单,价格低廉。可用于香焦、芒果、柑桔、石榴、苹果、梨、桃李、柿等多种水果和叶菜及瓜果类多种蔬菜。浸液干后,在果皮表面形成半透性高分子生物膜,能起气体微调节作用,减少氧气进入果实,较好地抑制鲜果呼吸作用、物质代谢、水份蒸腾等生理生化过程,推迟果实生理衰老,延长贮藏期,并有防止烂果的显著功效,起到综合保鲜作用。本品对人畜无害,不污染环境。
经本发明处理的各种水果,在20℃气温下的保鲜期,比未经处理的,可延长1-2倍,保鲜期分别可达:
苹果、石榴4-6个月;柑桔类2-3个月;
芒果、香焦、梨、桃、李、柿等1-2个月;
瓜果及果菜类约1个月
本发明防止烂果率的效果一般达90%以上,经济效益投出产出比为1∶10~15,即每投入1元的保鲜费,可多回收10-15元利润。
实施例:
按下述重量配比称取原料:
松香300克 虫胶200克 蜂蜡500克
噻菌灵7克(或山梨酸钾或苯甲酸钠6克)
将上述各组份制成本发明果蔬保鲜剂的生产方法是:
①接松香∶虫胶∶乙醇=15∶10∶100的重量配比,将松香和虫胶溶于乙醇溶液;
②按蜂蜡∶苛性钠=100∶1的重量配比,用常规方法对蜂蜡进行皂化;
③将①和②按0.5%的重量比,采用吐温作乳化剂,经乳化混合制成生物膜基质;
④在③中添加噻菌灵7克,搅拌均匀即可。
