Description

一种漆酶接枝改性壳聚糖协同棕榈乳液的复合包装纸涂布液
技术领域
本发明涉及包装纸技术领域，尤其涉及一种漆酶接枝改性壳聚糖协同棕榈乳液的复合包装纸涂布液。
背景技术
具有水蒸气阻隔性能的食品包装纸可以阻止食品中释放的水蒸气穿透纸张的微孔，从而达到减少水分损失和延长食品保鲜时间的功效。在过去的几十 年中，以石油作为原料来源的食品包装材料以其高机械强度和优良的水蒸气阻隔性能占据了包装市场的主导地位。可是，面对越来越严重的食品安全和环境问题，人们开始愈发的重视绿色无毒的新型包装材料。
目前，一些天然高分子类添加剂已经被应用于改善包装纸的阻隔水蒸气性 能，如壳聚糖、棕榈蜡、玉米蛋白等。其中其中，棕榈蜡因其安全无毒和优秀的水蒸气阻隔性能可用于开发具有阻隔水蒸气透过特征的绿色纸用助剂。棕榈蜡是一种由多种化合物组成的混合物，其主要包含有长链醇类、脂肪酸及脂类等。然 而美中不足的是，棕榈蜡本身在其工业应用的过程中很容易受到微生物的侵扰，从而影响产品的最终品质。壳聚糖具有良好的抗菌性能，现有技术中已经有将壳聚糖添加到纸张的制备中制造出抗菌纸，然而壳聚糖自身的抗氧化能力很低，且具有吸湿性，纸张又很容易吸水而影响某些包装产品的机械性能、印刷性能和尺寸稳定性。这就需要针对现有技术中存在的不足，拟将抗菌性能与阻隔水蒸气透过等性质集合与一体，制成包装纸的涂布液，满足食品专用包装纸的需求。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种漆酶接枝改性壳聚糖协同棕榈乳液的复合包装纸涂布液。
本发明是通过以下技术方案实现的：
一种漆酶接枝改性壳聚糖协同棕榈乳液的复合包装纸涂布液，将此涂布液对稻草浆制成的包装纸进行涂布，控制涂布量15g/m2，自然干燥制成复合涂布包装纸。
所述的利用一种漆酶接枝改性壳聚糖协同棕榈乳液的复合包装纸涂布液进行涂布的复合涂布包装纸，该复合涂布的包装纸可以用作蔬菜水果熟食等食品的保鲜。
所述的一种漆酶接枝改性壳聚糖协同棕榈乳液的复合包装纸涂布液，制备方法如下：
（1）将棕榈蜡加入39倍量的去离子水中，然后进行油浴加热至90℃，恒温状态下低速搅拌10分钟后加入适量的十二烷基二甲基胺乙内酯、纳米二氧化钛、N－羟基琥珀酰亚胺，转为高速搅拌20分钟，然后将产物放置在冰水浴中冷却，得到表面改性的抗菌棕榈蜡乳液；
（2）将壳聚糖溶于30倍量的pH为4的醋酸钠缓冲溶液中，搅拌均匀后加入与壳聚糖等量的对己氧基苯酚，水浴加热至45℃，以120转/份的速度搅拌8分钟后加入一定量的漆酶，搅拌反应5小时后静置离心去除杂质沉淀，加入适量浓度为1mol/L的氢氧化钠溶液至上清液中沉淀不再增加，然后用蒸馏水离心洗涤沉淀物10分钟，最后将产物冷冻干燥，得到漆酶改性壳聚糖；
（3）将步骤（1）产物与步骤（2）产物按照3:1的比例混合均匀即可。
所述的一种漆酶接枝改性壳聚糖协同棕榈乳液的复合包装纸涂布液的制备方法，步骤（1）中所述的低速搅拌是指以200转/分的搅拌，所述的高速搅拌是指转速为9000转/分的搅拌。
所述的一种漆酶接枝改性壳聚糖协同棕榈乳液的复合包装纸涂布液的制备方法，步骤（1）中所述的十二烷基二甲基胺乙内酯的添加量为棕榈蜡的2%，纳米二氧化钛的添加量为棕榈蜡的20%，N－羟基琥珀酰亚胺的添加量为棕榈蜡的3%。
所述的一种漆酶接枝改性壳聚糖协同棕榈乳液的复合包装纸涂布液的制备方法，步骤（2）中所述的漆酶的添加配比为每克对己氧基苯酚中添加500U漆酶。
本发明的优点是：本发明首先在十二烷基二甲基胺乙内酯的作用下为棕榈蜡乳液提供了额外的表面电荷，因此有利于形成粒径更小的微粒，同时有利于纳米二氧化钛聚集接枝到棕榈蜡乳液的颗粒表面，与普通棕榈蜡乳液相比，增强了抗菌性能，同时细小的乳液微粒通过涂布作用能够进入纤维网格的空隙之中，在涂布液干燥过程当棕榈蜡乳液经过加热融化更能够填满更小的孔洞并阻止更多的水蒸气的转移，从而有效地降低了其水蒸气透过率；然后通过漆酶协同对己氧基苯酚对壳聚糖进行改性，相比较于纯的壳聚糖，对自由基的抗氧化能力得到大幅提高，同时对己氧基苯酚在漆酶的作用下与壳聚糖上的游离氨基产生了共价键的连接，涂布到纸张表面可以提高纸张的强度。
本发明通过将表面改性的抗菌棕榈蜡乳液与漆酶改性壳聚糖按照一定的比例性能包装纸，同时具有极低的水蒸气透过率，适合用于涂布食品包装纸，产品在提供良好的阻隔水蒸气和抗菌性能的同时，还提高了纸张的机械性能，能够维持被包装蔬果等食品的新鲜度，同时工艺简单，节能减排，安全环保，值得推广。
