Description
技术领域
本发明属于抗菌纳米纤维膜制备的技术领域,具体涉及一种苦瓜籽油抗菌纤维膜及其制备方法。
背景技术
苦瓜是葫芦科苦瓜属植物苦瓜的果实,有“药用蔬菜”之称,有很强的药理活性。目前从苦瓜新鲜果实中已经分离出黄酮类、蛋白质类、有机酸类、皂苷类和生物碱类成分,并发现苦瓜具有降血糖、降血脂、抗病毒、抗癌等功能。苦瓜已被开发出多种功能性食品,如苦瓜饮料、凉茶、冰淇淋、罐头等,还被作为辅助降糖的保健食品,但对苦瓜种子的研究甚少,目前还未能引起人们足够的重视。
苦瓜籽,即苦瓜种子,在《本草纲目》中其中含有多种生物活性成分,包括油脂、蛋白质、多肽、番茄红素、苦瓜凝集素等。苦瓜籽油中含有多种脂肪酸,主要包括棕榈酸、硬脂酸、亚油酸和共轭三烯酸(包括α-桐酸、石榴酸和β-桐酸。研究表明,共轭亚麻酸(CLN)具有和共轭亚油酸CLN一样的降脂、抗癌、调节脂质代谢等功能,并且CLN的活性更强。苦瓜籽油是为数不多的富含α-桐酸的天然来源,其保健和药用价值受到越来越多关注。但苦瓜籽油具有强烈的不良风味,以及容易被氧化的特性极大地限制了它的应用和发展,对苦瓜籽油的开发利用却寥寥无几。
目前应用于提取苦瓜籽油的方法有熬制法、溶剂提取法、CO2超临界法等。但苦瓜籽油提取方法目前还存在许多需要解决的问题,如熬制法操作简单,但高温容易使油脂中不饱和脂肪酸被氧化;溶剂提取法不可避免地存在溶剂残留和生产安全性差的问题;CO2超临界萃取技术安全无毒,但提取效率不高。因此应当选择安全无毒且能高效提取的方法是必要的。公开号为CN103349849A的中国专利公开了一种“多功能连续相变萃取装置”,这项技术的应用范围广,能够实现安全、连续的动态萃取,且设备成本和运行成本都较超临界萃取装置低,适用于产业化生产。该技术的原理是利用萃取剂在不同压力和温度下的气、液态的两相变化,和高压下萃取剂的强穿透性,对天然活性物实现动态、高效的油脂萃取。低温连续体现在萃取剂在低于其临界压力和临界温度条件下压缩成液体,流经萃取釜对物料进行萃取后,在解析釜中相变为气体,其中萃取到的物质落入解析釜,解析后的气体再经过压缩成液体,再次流经萃取釜,对物料进行反复萃取的过程,此过程温度比常规炼油温度低很多,时间也大大缩短,并且可使用食品级安全无毒无害萃取剂,无有毒溶剂残留。目前低温连续相变技术应用在植物挥发油、色素等提取研究方面,提取苦瓜籽油成分的研究未见报道。
纳米纤维具有较小的直径和很大的比表面积,而纳米纤维膜具有高透气的特性,利用静电纺丝技术已经成功制备包括聚乙烯醇在内的多个高分子纳米纤维膜。苦瓜籽除含有油脂、蛋白质等,还含有倍半萜、苯丙素和单帖类物质,如反式橙花醇、香芹酮等,对金黄色葡萄球菌、大肠杆菌和白色念珠菌都具有抑制效果。在现有的文献中,未见苦瓜籽油-聚乙烯醇复合抑菌膜的研究。
发明内容
针对现有技术中的上述不足,本发明提供了一种利用低温连续相变萃取苦瓜籽中脂溶性物质的方法以及利用静电纺丝技术制备含苦瓜籽油的纳米纤维膜。本发明提供的苦瓜籽油,品质更好,且提取工艺简单稳定。本发明提供的纳米纤维膜,制备工艺创新且简单,具有优异的抑菌效果。
为实现上述目的,本发明提供如下技术方案:
一种苦瓜籽油抗菌纤维膜的制备方法,包括以下步骤:
S1.原料处理:将苦瓜籽粉碎过筛,得到苦瓜籽粉原料;
S2.低温连续相变萃取:将步骤S1所得苦瓜籽粉原料装入萃取釜,采用低温连续相变萃取,获得苦瓜籽中的脂溶性物质;
S3.苦瓜籽油乳液纺丝溶液制备:将步骤S2萃取的苦瓜籽油和表面活性剂加入水溶液中,进行剪切和微射流处理,得到苦瓜籽油纳米乳液,加入聚乙烯醇溶解,得到纺丝溶液;
S4.将步骤S3制备的纺丝溶液进行静电纺丝,得到苦瓜籽油-聚乙烯醇抗菌纳米纤维膜。
本发明整个萃取过程中,萃取剂有液态到气态再到液态的相变过程是即时、连续的,循环使用的。萃取得到的苦瓜籽油经过解析保存在解析釜中,萃取完毕后进行收集,获得了理想的萃取效果,并在低温和密闭的环境下很好地保存了苦瓜籽中的热敏性、不稳定物质,从而获得品质良好的苦瓜籽油。
作为本发明优选的技术方案,步骤S2中所述低温连续相变萃取工艺条件为:萃取温度为50-70℃,压力为0.5-0.7MPa,萃取剂为正丁烷,以120mL/h的流速流经萃取釜,连续萃取40-50min。
优选地,步骤S2中所述苦瓜籽粉原料的颗粒度为40目,所述低温连续相变萃取过程中,萃取温度为50℃,压力为0.7MPa,萃取时间为45min,解析温度为60℃。
本发明利用苦瓜籽油有效成分的抑菌功能,在此基础上结合高生物相容性高聚物的优点,通过静电纺丝技术,制备了以聚乙烯醇为壁材,负载苦瓜籽油的抗菌膜,形成具有纳米结构特点和含天然抗菌剂的抗菌材料。
优选地,步骤S3中所述苦瓜籽油乳液纺丝溶液中苦瓜籽油的质量分数为8%-12%,表面活性剂质量分数为3%-5%,聚乙烯醇质量分数为8%-12%。
优选地,步骤S3中所述水溶液温度为40℃。
优选地,步骤S3中所述表面活性剂为吐温-80。
优选地,步骤S3中所述剪切的转速为14000rpm-20000rpm,所述微射流的压力为800bar-1400bar,流速为70mL/min-120mL/min。
优选地,步骤S4中所述静电纺丝工艺中,纺丝电压为16KV-20KV,接收距离为12cm-16cm,推进速度为0.4mL/h-0.8mL/h。
本发明还同时保护采用上述方法制备得到的苦瓜籽油抗菌纤维膜。
与现有技术相比,本发明的有益效果是:
(1)本发明采用低温连续相变萃取技术萃取苦瓜籽油,萃取过程在密闭绝氧、避光和低温低压的条件下进行,与常规方法相比,苦瓜籽油的酸价和过氧化值均大大降低,提高了苦瓜籽油的品质、保存活性物质、适应规模化生产,也适用于热敏性、光敏性以及易氧化酸败的油脂工业化生产。
(2)本发明在苦瓜籽油-聚乙烯醇抗菌膜的制备方法中,采用乳液静电纺丝的方式制备纳米纤维膜,由于苦瓜籽油在常温下呈现半固体状的限制,所以,本发明在制备苦瓜籽油纳米乳液和纺丝溶液的同时,通过加热溶液和高压微射流通道的方式维持整体溶液的温度,从而使苦瓜籽油的乳液颗粒均匀地分布于纺丝溶液中,制备成苦瓜籽油抗菌纳米纤维。
(3)本发明将从苦瓜籽提取的油状液体应用于静电纺丝制备纳米纤维膜中,不仅增加了苦瓜籽油的氧化稳定性,也开发了苦瓜籽油的抑菌功能和用途,减少因苦瓜籽油的不良风味带来的应用限制。

结合图3和表2的结果显示,本发明提供的苦瓜籽油抗菌膜对大肠杆菌和金黄葡萄球菌有明显的抑制效果,对大肠杆菌的抑菌圈大小为22.3±0.4mm,最低抑菌浓度为25mg/mL,对金黄葡萄球菌的抑菌圈大小为20.7±0.3mm,最低抑菌浓度为30mg/mL,具有优良的抑菌性能。
实验例4储存稳定性
过氧化值的测定方法:采用二甲酚橙法,用紫外分光光度计(UV-1750,SHIMADZUCO.,Japan)测定溶液的吸光度,建立了过氧化值与吸光度的线性回归方程。H2O2溶液的最大吸收波长为560nm。根据浓度配制一系列H2O2标准甲醇溶液(10-70mmol/Kg),分别加入一定量的FOX试剂。测定了一系列H2O2溶液在560nm处的吸光度,建立了与吸光度对应的过氧化值的线性回归方程。采用相同的方法测定不同时期(0、5、10、15、20、25天)、不同样品(包埋和未包埋)和不同保存条件(有氧和无氧)的吸光度,得到苦瓜籽油的氧化情况。测定结果见图4,本发明制备的苦瓜籽油包埋于纳米纤维膜中储存稳定性更好。
本发明的上述实施例仅仅是为了清楚地说明本发明技术方案的所作的举例,而并非是对本发明的具体实施方式的限定。凡在本发明权利要求书的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本发明权利要求的保护范围之内。
