Description
技术领域
本发明涉及保健饮料技术领域,具体涉及一种柿子叶保健饮料的制备方法。
背景技术
随着生活水平的提高,人们对饮料的需求量越来越大,人们的个人生活中、餐桌上都少不了各种饮料,如各种各样的碳酸饮料、果汁、奶制品饮料、碱性饮料满足了人们对各种口味的需求。随着社会竞争力的增加,人们的工作压力也越来越大,各种功能饮料也逐渐的诞生,如红牛、乐虎、加多宝等。且随着生活水平提高,人们对饮料的质量要求也越来越高,也更加注意到饮料对身体健康的重要性,对饮料的选择的要求愈来愈高,不但要求口感好,而且要求具有保健功能,故保健饮料己成为当今饮料市场的热点。保健饮料在我国近几年才发展起来的新型产业,尚处于初级发展阶段。保健饮料更科学的叫法是功能性饮料,功能饮料是指通过调整饮料中天然营养素的成分和含量比例,以适应某些特殊人群营养需要的饮品,包括营养素饮料、运动饮料和其它特殊用途饮料三类。中药保健饮料集传统与现代元素于一身,与传统的纯净水相比,口感好、解暑、有营养、生津止渴强,比曾经走红的碳酸饮料更止渴、更健康、更爽口、更提神,有望成为未来的饮科主角。柿子叶黄酮类,大多以苷的形式存在。黄酮类化合物的生物活性一直为国内外学者所关注,具有卓越的抗氧化活性,研究显示其具有消炎解热,治疗慢性肾炎蛋白尿,治疗血小板减少性紫癜、软化血管、减肥、抗氧化、防止动脉硬化、降血脂和降低血压以及治疗黄褐斑的作用,市面上尚未有以柿子叶为原料的保健饮料,因此,有必要开发一种柿子叶保健饮料的制备方法。
发明内容
本发明的目的是为解决上述技术问题的不足,提供一种柿子叶保健饮料的制备方法,以柿子叶提取物、蓝莓汁和黑木耳作为保健饮料的主要成分,富含蛋白质、黄酮、黑木耳多糖和多种维生素及微量元素,口感酸甜适中,风味独特,还具有降血脂及改善骨质疏松的保健作用。
本发明为解决上述技术问题,所提供的技术方案是:一种柿子叶保健饮料的制备方法,包括以下步骤:
(1)、取柿子叶,洗净后置入蒸笼中,蒸锅的水中加入食盐,中火蒸制5-8分钟,然后取出,清洗后烘干,并粉碎过50目筛,得到柿子叶粉,备用;
(2)、柿子叶粉与10%乙胺按1:8比例在70℃浸提1.5小时,过滤、滤渣,再与70%乙胺按1:5比例在70℃浸提1小时,合并两次滤液;回收乙醇,再加入蒸馏水,过滤,得柿子叶提取液,备用;
(3)、 取黑木耳,烘干后粉碎过50目筛,得到的黑木耳粉按1:30的料液比,放在50℃-70℃水浴锅中浸润30分钟,浸润结束后用微波协同超声波提取多糖,提取结束后,离心取上清液,加入3倍于溶液的乙醇,静置1-2h,离心出去上清液,取沉淀、洗涤和粉碎,得到黑木耳多糖干粉,备用;
(4)、取新鲜蓝莓果实进行挑选,去除枝叶碎石等杂质,剔除病虫害或霉变果实,然后将蓝莓果实采用压滤机进行压榨,去除果渣,得到蓝莓汁,备用;
(5)、按照重量百分比取步骤(1)制得的柿子叶提取液15-20%、步骤(4)制得的蓝莓汁10-15%、步骤(3)制得的黑木耳多糖4-5%、维生素0.1-0.2%、蜂蜜1-2%以及余量的水,混合均匀,然后在115-135℃下杀菌5-6分钟,最后进行灌装。
作为本发明一种柿子叶保健饮料的制备方法的进一步优化:所述步骤(3)中微波协同超声波提取具体操作为:微波功率680-850W,微波30-50秒,再加入水,在超声波700-900W的功率下超声3-5分钟。
有益效果
一、本发明的保健饮料制备方法将柿子叶提取液和蓝莓汁进行复合,并且加入了提取得到的黑木耳多糖,使得最终制得的饮料含蛋白质、黄酮、黑木耳多糖和多种维生素及微量元素,口感酸甜适中,风味独特,还具有降血脂及改善骨质疏松的保健作用。
二、本发明的保健饮料制备方法中,在柿子叶提取液,先置入蒸锅中,利用含有食盐的水进行蒸制,能够去除一部分柿子叶本身带有的涩味,保证最终制得饮料的口感宜人。
三、本发明的保健饮料制备方法中,以柿子叶提取液为主要原料,不添加其他任何化学成分,提取液中含有的花青素累成分为天然的抗菌剂,无需另外添加抑菌剂,并且,由于提取液内黄酮含量较好,也不必再添加柠檬酸等调味剂来调节酸度,健康营养,易于人体吸收。
