Abstract
本发明涉及通过用与可与水混熔的包衣材料包衣含乳酸菌的种子,然后如果需要再将第一包衣产品用控释包衣材料进行第二次包被而制备的肠包衣颗粒。
Description
技术领域
本发明涉及用于更好地稳定乳酸菌的肠包衣微颗粒。在本发明说明书中,术语“乳酸菌”指对健康有益的细菌,它们存在于人肠中并有助于肠的活性蠕动。
背景技术
由生物体摄入的乳酸菌可防止食物的异常发酵并激活肠功能,由此改善肠的功能性异常如便秘、腹泻等并保持健康。另外,将乳酸菌加至饲料中可防止因家畜肠内的异常发酵而引起的气体积累、便秘、腹泻等(所述异常发酵可能是由相同饲料的重复供应而引起的),从而最终改善肉的质量并有助于乳牛场的发展。
但是,尽管乳酸菌有很大的用途和很高的价值,但由于其酸不稳定性,而使乳酸菌的实际应用受到很多限制。即由于乳酸菌在pH4以下是非常不稳定的,所以,在胃液的酸度(约pH2)下,绝大部分被摄入的乳酸菌被破坏。因此,只有极少量被摄入的乳酸菌(约百万分之一)能活着到达肠。结果,需要花费许多时间和金钱来制备乳酸菌以便使其在人肠中有效地发挥其功能。
为了克服上述问题,在食品和药物工业领域已经提出了一种提高到达肠的乳酸菌的数量的方法,该方法使用过量10倍以上的该细菌。但是,这不是一种解决问题的根本的方法,只不过是一种很不完整且很浪费的暂时补救措施。此外,最近报道了含微颗粒的食物,其中将乳酸菌与脂肪、乳化剂和保护材料混合,然后以胶囊包封而制成,其目的是通过使细菌在胃液中存活来提高到达肠的乳酸菌的比例(参见韩国专利公开97-25405)。但是,根据试验结果,已经确定,在所述包封的乳酸菌被摄取后,不论是在胃液还是在肠液中,其包衣均在30分钟内崩解。从其他试验还注意到,用明胶作为包衣基料的市售乳酸菌在任何环境下均可以在10小时以上的时间内都不会崩解,对于对胃液或肠液的特异性而言,没有差异(参见试验实施例1)。显然这是由于用作乳酸菌包衣基料的材料是一种常规材料,这种材料不与胃液或肠液敏感地发生反应。此外,在普通药物领域,已报道了利用各种聚合物作为有机溶剂基料进行包衣的许多方法(参见PCT/JP94/001675、日本专利申请91-235667、92-364123、92-41434、93-186335、93-186336等)。但是,所述包衣技术不能令人满意地保护乳酸菌免受胃液的作用。具体地讲,如果用有机溶剂作为被包衣制剂的溶剂或者如果包衣方法是在55℃以上的高温下完成,则乳酸菌在人体内的实际存活率远比预期值小。
另一方面,已经尝试开发有高酸耐受性的乳酸菌的变异菌株。但是,这种方法需要大量的时间和很高的成本,而且比包衣方法有更坏的影响。
本发明的公开
本发明人对肠包衣技术进行了大量的研究,就乳酸菌的稳定性和经济性而言,取得了一些有价值的成绩。结果,我们已发现当将乳酸菌先用一种可与水混溶的包衣材料包被,然后,如果需要再用常规控释包衣材料进行包被时,可使在制备包衣颗粒过程中的乳酸菌破坏程度大大降低,此外,可产生通过安全地保护乳酸菌免受胃液的攻击而能够将包含于其内的乳酸菌传递至靶器官即肠的包衣颗粒,在所述靶器官中,乳酸菌可实际发挥其功能。因此,我们已完成了本发明。在本发明中,由于包衣颗粒含有高比例的活的乳酸菌,而且对酸很敏感,所以其内所含的细菌可在人的胃液环境下存活,然后在肠中所述颗粒被迅速崩解。
因此,本发明的目的之一是提供一种特别设计的肠包衣微颗粒以便通过最有效地稳定颗粒中所含的乳酸菌而使所述乳酸菌在肠中发挥功能。完成本发明的最佳方式
下面更具体地解释本发明含乳酸菌的包衣颗粒。
通过先在低温用与可与水混溶的包衣材料包被含乳酸菌的种子,然后如果需要将第一次的包衣产物用控释包衣材料进行第二次包被,这样可制备本发明含乳酸菌的包衣颗粒。在本发明中,通过在低温用与可与水混溶的材料完成第一次包被,可将制备过程中对乳酸菌的破坏程度降至最小。
在本发明中,可将一种或多种对人类有益的菌株作为本发明中的乳酸菌菌株,所述菌株选自链球菌属、乳酸球菌属、嗜柠檬酸明串球菌属、小球菌属、肠球菌属、乳酸杆菌属和双歧杆菌属。
可用于第一次包被的可与水混溶的包衣材料包括以藻酸钠为主要成份的海藻(例如褐海藻)提取物、藻酸、聚异丁烯酸甲酯[EudragitL30D,Eudragit LS30D,Kollicoat MAE 3DP(由BASF公司制造)]、小麦蛋白、大豆蛋白、甲基纤维素(MC)、羟丙基纤维素(HPC)、羟丙基甲基纤维素(HPMC;药物包衣,水溶性包衣等)、聚醋酸乙烯酯邻苯二甲酸酯[Sureteric;由Colorcon Co.制造]、胶类例如瓜尔胶、槐树豆胶、黄原胶、gellan胶、阿拉伯胶等。由于这些可与水混溶的包衣材料是水溶性的或水可分散的,所以用水作为溶剂是有益的,这样可以方便地完成第一次的包衣过程。不将既对人体有害又对乳酸菌致命的任何有机溶剂用于包衣过程是非常重要的,并因此完全解决了除去残留有机溶剂的问题。这是本发明不同于现有技术的有益之处,现有技术必需使用有机溶剂来溶解作为包衣材料的大分子物质。在本发明中,藻酸钠优选用作可与水混溶的第一包衣材料。其原因是藻酸钠是水溶性的,而且其水溶液是中性的,因此对于乳酸菌的稳定性更有利。
用于包衣过程的种子可以是乳酸菌本身或者乳酸菌与一种或多种选自下列添加物质的混合物:淀粉、乳糖、寡糖、糖醇、葡萄糖酸钙、乳酸钙和葡萄糖酸。加入这些添加物是为了将乳酸菌稀释到所需的比例,仅激活乳酸菌而抑制其他细菌菌株,或提高乳酸菌的增殖。
在第一次包衣过程中,优选将可与水混溶的包衣材料以种子重量1-80%的量使用。
尽管如上所述制备的乳酸菌的第一包衣颗粒本身就足够有效,但用常规的控释包衣材料第二次包衣后,它可以得到更有效地使用。因此,带有第一和第二包衣的肠溶包衣微颗粒也包括在本发明的范围内。
作为第二包衣材料,可以使用药物领域常用的控释包衣材料,特别是肠溶包衣材料;或者膨胀性的包衣材料如carbopol或阿拉伯胶;以及其他控释包衣材料。更具体地讲,有玉米蛋白提取物(在USP/NF中描述的)和其人工加工的材料如Zein-DP或醇溶蛋白、藻酸钠、藻酸、聚异丁烯酸甲酯例如Eudragit L30D、Eudragit LS30D、Kollicoat MAE3DP(由BASF Co.制造的)等,虫胶、羟丙基甲基纤维素邻苯二甲酸酯(HPMCP)、羟丙基甲基纤维素(HPMC)、羟丙基甲基纤维素乙酸琥珀酸酯(HPMCAS)、羰甲基纤维素(CMC)、羟丙基纤维素(HPC)、纤维素乙酸邻苯二甲酸酯(CAP)、聚乙酸乙烯酯邻苯二甲酸酯[Sureteric(Colorcon Co.)]、乙基纤维素(EC)、甲基纤维素(MC)、大豆蛋白或小麦蛋白(它们被登记为食品添加剂)、几丁质、几丁酸(chitinic acid)、琼脂、角叉菜胶、果胶、carbopol或胶类如瓜尔胶、槐树豆胶、黄原胶、gellan胶、阿拉伯胶等。其中,优选将选自玉米蛋白提取物、羟丙基甲基纤维素邻苯二甲酸酯(HPMCP)和虫胶中的一种或多种用作第二包衣材料。
在进行第二次包衣的过程中,将上述一种或多种包衣材料以经第一次包衣的颗粒重量的1-95%的量使用。具体地讲,当使用药物领域常用的肠溶包衣材料时,将其以1-40%(重量)的量使用;或者当使用膨胀性的其他包衣材料时,将其以30-95%(重量)的量使用。包衣材料的种类和量由所属领域技术人员根据包衣材料的特性和包衣材料的使用目的适当地加以确定。
与其中仅用水作为保护乳酸菌的溶剂的第一包衣不同,第二包衣可以使用一种或多种选自下组的各种溶剂:水、乙醇、丙酮、乙腈、二氯甲烷、乙醚、己烷、氯仿、1,4-二氧六环、四氢呋喃、二甲亚砜、乙酸乙酯和乙酸甲酯。在包衣材料几乎不溶于溶剂的情况下,如果需要,可以用pH调节剂如乙酸、盐酸、磷酸、各种缓冲溶液、柠檬酸、酒石酸、苹果酸等将pH调至所需的范围,由此改善包衣材料的溶解度。这是所属领域技术人员很容易完成的。
当进行第一和第二次包衣过程时,在相应步骤中所用的包衣材料应彼此不同。如果需要,在第一或第二包衣过程中,可以使用选自下组的一种或多种增塑剂:聚乙二醇、myvacet、丙二醇、甘油、柠檬酸三乙酯、甘油三乙酸酯、鲸蜡醇和硬脂醇。在这种情况下,优选将增塑剂以所用包衣材料重量1-50%的量使用。
在制备包衣颗粒过程中,为了最有效地稳定乳酸菌,本发明人使用了下列方法,其中(a)悬浮含乳酸菌的种子,同时用包衣溶液喷雾包被,或(b)将悬浮在包衣溶液中的种子分散到小室中。因此,通过应用所述过程,可以更好地完成本发明。
通过使用流化床造粒机、CF-造粒机等(优选流化床造粒机(SFC-MINI),Freund Co.,Japan))可以完成包衣过程。当使用所述造粒机时,优选将被导入空气的温度保持在40-70℃。颗粒在造粒机各步骤中的温度应保持高于20℃以防止颗粒从环境气体中吸收湿气并彼此聚集。由于当温度超过55℃时,乳酸菌会受到破坏,因此优选在整个过程中将颗粒温度保持在25-55℃。

为了检测在实施例1-9中制备的包衣颗粒在人工胃液和肠液(按照USP制备的)中是否有任何改变,完成下列体外试验。然后,将所得结果与市售产品Dr.Capsule(Binggrae Co.)和Bifidus菌株源粉末-1(108倍)(Cell Biotech.Co.)的结果相比较。
每次将10g的一种被包衣的乳酸菌在100毫升人工胃液中以50rpm搅拌1小时,然后将残余物转移到100毫升人工肠液中。将包衣的乳酸菌在人工肠液中缓慢搅拌5小时,然后进行保温(培养基:Elliker肉汤;培养条件:无氧,37℃,72小时)。然后通过检查肉眼可见到海绵相出现的时间来确定乳酸菌的崩解程度。在表2中,在人工肠液中的崩解数据表示100%的包衣颗粒崩解时的时间,然后按照下列等式计算存活率在上述等式中,
A代表在胃液中搅拌1小时和在肠液中搅拌5小时,然后保温后得到的乳酸菌数,和
B代表仅在肠液中搅拌5小时然后保温后得到的乳酸菌数
表2中所列的结果是三次重复的平均值。

正如从上述表2所见到的,与市售的现有产品相比,本发明的乳酸菌包衣颗粒在人工胃液中有更高的存活率,而且能在肠中迅速崩解。因此,按照本发明制备的乳酸菌包衣颗粒是能够以最佳方式调节乳酸菌体内活性的最佳形式。
