Description
技术领域
本发明涉及功能糖技术领域,具体地说是一种可直接压片的木糖醇颗粒及其制备方法。
背景技术
木糖醇是一种天然的食用保健糖醇,是人类正常的糖代谢中间体。它的化学分子式是C5H12O5,白色结晶或结晶性粉末,极易溶于水。木糖醇以其无糖、保湿、甜味、保健等功能特性,应用于食品、医药原料。由于木糖醇对于保护牙齿、口腔护理、预防耳炎、清新口气都有很好的功效,为了能使其在口腔中的功效发挥的更好,目前木糖醇已被制成多种形式的含片。然而木糖醇具有较强的吸湿性,因此流动性差,不易直接压片,所以想要对木糖醇压片就必须克服上述不利条件。目前,国内外已有相关可用于压片的木糖醇的专利报道。
国内多采用添加粘合剂的湿法制粒技术,如专利CN200410070541.8《可直接压片的木糖醇颗粒及其制造方法》、CN201110453099.7《一种可直接压片的木糖醇及其制备方法》、CN200810238544.6《一种DC级木糖醇湿法制粒制备工艺》和CN200510068255.2《一种可直接压片的木糖醇颗粒及其制备方法》中提到的技术方法。该技术方法较为原始,操作步骤繁琐,且粘合剂较难溶解,需大量的水或其他溶剂配制成溶液,造粒过程中容易出现粘堵筛网现象,另外还需要增加烘干设备进行烘干,以上专利的配方中还加入了其他多元醇或其他甜味剂,降低了木糖醇纯度。
专利CN200810238544.6《可直接压片的木糖醇颗粒及其制备方法》采用的较为先进的沸腾造粒方法,但工艺中一部分粘合剂也需要用热水配成溶液然后以喷雾的方式喷洒到物料上,粘合剂配制过程比较繁琐还需要过滤掉没有溶解的大颗粒,并且需要趁热使用。该方法所造的颗粒为利于形成压片、提高压片硬度添加的粘合剂量比较大,并且在压片过程中还要添加硬脂酸镁,这不只提高了造粒和压片的成本,而且还降低了颗粒和压片中木糖醇纯度
发明内容
本发明的技术任务是提供一种可直接压片的木糖醇颗粒及其制备方法。
本发明的技术任务是按以下方式实现的:
一种可直接压片的木糖醇颗粒,该木糖醇颗粒的质量百分比成分为:木糖醇含量为98~99%,粘合剂含量为1~2%。
所述的粘合剂为羧甲基纤维素钠。
一种可直接压片的木糖醇颗粒的制备方法,该方法的步骤如下:
步骤1)粉碎混合上料:将木糖醇粉碎成100目以下的粉末,添加粘合剂粉末混合,将混合均匀的粉末装入沸腾造粒机料箱内准备制粒;
步骤2)准备润湿剂:向喷液贮罐中加入润湿剂备用;
步骤3)造粒:开启所述的沸腾造粒机使物料在设备内呈流化状态,将造粒温度设定为40~60℃,将润湿剂以喷雾的形式,不断喷洒到物料颗粒之间,在1~2小时内喷完所需的润湿剂;喷完后,开热风至70~90℃,烘干0~40min,再开冷风降到室温,然后用筛子筛分出颗粒;
步骤4)压片:将所得颗粒用压片机直接压成片剂,得到高硬度、高纯度木糖醇片剂。
所述的步骤1)中木糖醇的纯度≥99.5%。
所述的步骤1)中粘合剂为羧甲基纤维素钠,所述的粘合剂粘度范围为800~1600mPa.S,所述的粘合剂添加比例为木糖醇质量的1~1.5%。
所述的润湿剂为纯水,所述的纯水的用量为木糖醇质量的0.5~1.50%。
所述的步骤3)中用筛子筛分出的颗粒的粒径为20~80目。
所述的颗粒中水的质量含量为0.15~0.3%,木糖醇的质量含量为98~99%,粘合剂的质量含量为1~2%。
本发明的一种可直接压片的木糖醇颗粒及其制备方法和现有技术相比,通过生产过程中调节粘合剂用量、润湿剂种类和用量、造粒温度和时间、烘干温度和时间、粒度大小、含水量等指标,制作出直接压片硬度大的颗粒。粘合剂干粉直接和物料混合,不用再另外进行溶解,且物料混合、制粒、烘干在同一设备内进行,生产过程简单操作方便。制粒所用粘合剂量少,目前木糖醇颗粒在压片过程中为提高压片的硬度会添加硬脂酸镁等作为助流剂,而本方法制作的颗粒流动性和可压性高,可以直接进行压片所制压片硬度≥150N,压片中木糖醇纯度≥98%,压片过程中不添加其它辅助成片物质既能提高压片中木糖醇的纯度又能降低压片成本。
