Description
技术领域
本发明属于食品加工技术领域,特别涉及一种苹果多酚纳米脂质体粉末的制备方法。
背景技术
苹果多酚是从苹果中提取,在未成熟果实,比如落果中,以及苹果榨汁后皮渣中含量丰富。苹果多酚在食品行业中应用,具有抗氧化,防止腐败,保持原有色泽,消除异味,防止维生素损失的作用,作为具有保健作用的活性成分,具有预防高血压、预防过敏反应,清除自由基,减少紫外线伤害等功效。苹果多酚作为保健和功能性食品添加剂,50-500 mg/kg就可以发挥功效。但同其它来源的多酚一样,苹果多酚在贮藏过程中,易被氧化失活,部分或者全部失去功效。因此,其在贮藏和使用中的稳定性是一个需要解决的问题。
苹果多酚的缓释,在减少其活性氧化损失的同时,又能实现苹果多酚功能的长效、持续的起作用,不至于出现浓度过高或不足的现象。实现苹果多酚缓慢释放的技术有多种,如微胶囊技术、多孔微球技术和脂质体技术。其中,脂质体技术由于其特有的双分子结构,既可以包埋亲水性也可以包埋亲脂性物质,在食品包埋材料的制备与加工领域应用前景更广。纳米脂质体可以更为有效的保护负载活性物质的生物活性,并能将负载的活性成分缓慢释放进入血液,以起到平稳持续的生物功效。
本发明通过将苹果多酚采用脂质体技术进行包埋,然后制备成苹果多酚纳米脂质体粉末,其目标在于防止苹果多酚氧化,保护苹果多酚生物活性,并起到缓慢释放苹果多酚,持续发挥抗氧化功效的作用。
发明内容
本发明的目的是提供一种苹果多酚的纳米脂质体,以延缓苹果多酚的氧化过程,并提供一种苹果多酚的持续、缓慢、平稳的释放。
为达到上述目的,本发明采用的技术方案为:
一种苹果多酚纳米脂质体粉末的制备方法,原料包括苹果多酚、大豆卵磷脂、胆固醇、VE、乳化剂和冻干保护剂,其特征在于,苹果多酚经脂质体包埋,纳米乳化后冷冻干燥、研磨而成,其优选的制备步骤如下:
(1)将适量多酚和海藻酸钠溶解于25℃蒸馏水中,最终多酚的浓度为3-5 mg/mL,海藻酸钠为80-120 mg/mL;
(2)将大豆卵磷脂、胆固醇、VE、Span 80和Tween 20按照2%、0.5%、0.5%、0.125%、0.125%的终浓度依次定容于适量大豆油中;
(3)将步骤(2)中获得的溶液在50℃下,300 rpm搅拌10 h,然后按照体积比1:5的比例加入到步骤(1)获得的溶液里;
(4)将步骤(3)中获得的溶液在12000-18000 rpm,40-60 ℃,搅拌3-5 min,然后在50℃下,300 rpm继续搅拌30 min;
(5)将(4)中得到的溶液,在-40℃冷冻24 h,然后在-50~-60℃,1 Pa条件下冷冻干燥48 h,然后在20℃下干燥10 h,研磨,得到一种苹果多酚的纳米脂质体。
所述的一种苹果多酚纳米脂质体粉末的制备方法,其中,所述的一种苹果多酚纳米脂质体粉末的制备步骤中各个工艺条件都是经过单因素实验得来,然后经过正交实验进行优化,得到优化方案。
所述的一种苹果多酚纳米脂质体粉末的制备方法,其中,大豆卵磷脂具体的说是磷脂酰胆碱,其作用在于为多酚提供既亲水又亲脂的双层膜的包埋。
所述的一种苹果多酚纳米脂质体粉末的制备方法,其中,胆固醇起到了控制膜的流动性的作用,维生素E起到了抑制磷脂酰胆碱的被氧化的作用,Span 80和Tween 20的起到了表面活性剂的作用,海藻酸钠起到了冻干保护剂的作用。
所述的一种苹果多酚纳米脂质体粉末的制备方法,获得纳米脂质体乳液后经冻干而成产品,与以薄膜法、喷雾干燥法等制备的其它脂质体相比,其优点在于制备过程避免了高温,减少了高温给苹果多酚带来的氧化能力损失,保护了苹果多酚的抗氧化能力。
所述的一种苹果多酚纳米脂质体粉末的制备方法,制备所得的纳米脂质体乳液粒径在180-320 nm,包封率均超过98.5%。
本发明的有益效果是:
(1)本发明制备的一种苹果多酚纳米脂质体粉末,苹果多酚经过脂质体包埋技术保护,减少了直接与外界温度、水分、氧气的接触,保护了苹果多酚的抗氧化性能,可稳定储藏8个月以上。
(2)本发明制备的一种苹果多酚纳米脂质体粉末,可以通过纳米包埋缓释的原理,使苹果多酚缓慢平稳的释放,避免了苹果多酚浓度的大起大落,起到了持续、平稳起作用的效果。
(3)本发明制备的一种苹果多酚纳米脂质体粉末,既溶于水,又溶于脂,方便在各种食品中添加,也方便在体内消化吸收。
(4)本发明制备的一种苹果多酚纳米脂质体粉末,在制备过程中采用了真空冷冻干燥技术,不采用喷雾干燥,也不采用旋转蒸发,减少了高温对苹果多酚抗氧化能力带来的损失。
