Description

一种以乙醇作为脱水剂的淀粉基质膜制备的快速脱水方法
技术领域
本发明涉及一种以乙醇作为吸水剂的淀粉基质膜制备的快速脱水方法。可广泛应用于包装坚果、糕点、糖果等食品，属于食品加工领域。
背景技术
以淀粉为主要基质的膜材作为食品包装材料，具有食用安全及环保性。天然高分子可降解包装材料的研究主要以多糖、蛋白质、脂质等为原料, 通过包裹、浸渍、涂布、喷洒覆盖于食品界面上的一层可食物质组成的包装薄膜。淀粉原料来源广泛，具有糖类营养；淀粉膜包装防止食品中水、油及其他成分的迁移和扩散；阻止食品风味物质的挥发；可与被包装食品一起食用，对食品和环境无污染；提高产品质量，延长产品的货架期。
传统上淀粉膜应用以糯米膜包装糖果为主，现今人们在开发淀粉基缓释胶囊，加入一些低级醇、酯、酸度调节剂、动植物胶、修饰淀粉、多糖、糖胺聚糖等改性剂。目前研制的淀粉膜的实用性较差，在机械性能差，易老化变脆。同时，存在生产周期长、不能工业化生产的缺点。尤其是脱水干燥过程需要自然通风干燥，耗费时间。
乙醇作为吸水剂，具有以下特点：（1）可任意比例与水混溶，是良好的吸水剂；（2）具有良好的挥发性，和可回收性；（3）来源广泛，价格便宜。乙醇在与未完全失水的淀粉膜接触后，利用其良好的、适中的吸水性将淀粉膜中游离水吸去，保留结合水，可加速淀粉膜脱水过程。
发明内容
本发明的目的就是提供一种以乙醇作为脱水剂的淀粉基质膜制备的快速脱水方法，该方法具有材料来源广泛，成本低廉，操作简便快捷，安全环保，可回收的特点。
本发明的目的是通过以下的技术方法来实现的：
A、将淀粉配制成3～20%的稀释液，加入质量分数为1～10%的增塑剂和增强剂，1%硬脂酸甘油单酯为乳化剂。匀浆，混合液于79～99℃下糊化30～120min，得糊化液。糊化液于超声脱泡10min；
B、脱泡的糊化液涂布在模具上，20～70℃条件下干燥1～4h得预干燥膜；
C、将模具和预干燥膜浸入90～99%乙醇中5～15min，取出，待残余乙醇挥发净，揭膜。
所述的淀粉包括玉米淀粉、马铃薯淀粉、魔芋粉、修饰淀粉及其它淀粉或其复合淀粉。
所述的增塑剂和增强剂包括丙三醇、甘露糖醇、麦芽糖醇、木糖醇、乙二醇、油酸、棕榈酸、明胶、琼脂、葡甘聚糖、羧甲基纤维素钠、海藻酸钠及其相似物质中的一种或几种协同作用。
所述的模具其材料包括具有涂布面的玻璃、金属、特氟龙及其它相似材料。
本发明以乙醇为脱水剂，利用其良好的、适中的吸水性将淀粉膜中游离水吸去，保留结合水，可加速淀粉膜脱水过程。
本发明各参数、工艺步骤相互作用，构成一个完整的技术方案。
本发明材料成本价格低廉、工艺时间大幅缩短、产品安全可食。
具体实施方式
以下实施例用于说明本发明，使其更明确，但决不用来限制本发明的范围。
实施例1：
1）将5g玉米淀粉加入至100ml蒸馏水中，稀释并混合均匀；
2）混合液加入2g海藻酸钠作为增强剂，3ml甘油作为增塑剂，1g硬脂酸甘油单酯作为乳化剂，80℃匀速搅拌40min至淀粉充分糊化；
3）糊化液经超声脱泡10min；
4）取20ml脱泡后的糊化液涂布在玻璃模具上，60℃条件下干燥2h；
5）取出玻璃模具，将95%乙醇倒入模具内将淀粉膜浸泡10min，乙醇吸去膜中剩余水分后倒出乙醇，待残余乙醇挥发净，揭膜。
