Pigment, and named. “Lutein”; With the development of biophysical technology, people have separated a series of natural pigments by chromatography and named it “carotenoids”. They have a common chemical structural feature, and the center of the molecule is a polyisoprene long chain with polyene bonds. Many derivatives are produced by cyclization at the end, addition of oxygen, or rotation and isomerization of bonds. At present, there are about 600 known carotenoid members.

Description

一种高生物利用度的类胡萝卜素油悬浮液及其制备方法 技术领域
本发明涉及通过直接雾说化类胡萝卜素溶液使其中的类胡萝卜素 晶体以极细小颗粒悬浮于植物油中， 从而得到一种流动性好， 生物利 用率高的油悬浮液剂型。 属于生物化工领域。
书 背景技术
类胡萝卜素在自然界中广泛存在， 1831年， Wachenroder从胡萝 卜根中首次结晶分离出碳水化合物类的色素， 并以"胡萝卜素"命名； 之后， Berzelius从秋天的叶片中分离提取出黄色的极性色素， 并命名. 为"叶黄素"； 随着生物物理技术的发展， 人们通过色谱方法分离出一 系列的天然色素， 并命名为"类胡萝卜素"。 它们具有共同的化学结构 特征， 分子中心都是多烯键的聚异戊二烯长链， 通过末端的环化、 氧 的加入或键的旋转及异构化等方式产生出许多衍生物。 目前， 己知的 类胡萝卜素成员大概有 600多种。 类胡萝卜素 (Carotenoids)属于类萜化合物， 是胡萝卜素 (Carotene) 和叶黄素 (Xanthophylls)两大类色素的总称。分子中不含有氧原子的碳 氢族类胡萝卜素称为胡萝卜素族； 分子中含有氧功能团 (如羟基、 环 氧基、 甲氧基、 酮基、 羟基等)的衍生物及其酯类则称为叶黄素族。 自然界存在的类胡萝卜素有数百种之多， 但比较常见且数量相对 较大的主要有六种， 它们分别是 β-胡萝卜素、 虾青素、 斑蝥黄素、 叶 黄素、 玉米黄质和番茄红素等。 随着生物技术和合成技术的发展， 这 六大类胡萝卜素中许多种类又存在着多种来源， 如 beta-胡萝卜素可 以是全合成， 又可通过发酵法或养殖盐藻得到， 还可从天然物如棕榈 油中提取； 番茄红素可以是天然来源如从番茄中提取或发酵得到， 也 可是全合成的； 在这些类胡萝卜素中叶黄素是个例外， 由于结构上的 不对称性， 目前只有通过从植物中提取， 而不会高成本地合成。 这六种类胡萝卜素在分子结构上都较为相似， 是一类碳氢化合物 及其氧化衍生物， 它们由 8个类异戊二烯单位组成， 只是在两个末端 六元环上存在细微的差别。类胡萝卜素分子结构中存在的多个共轭双 键发色基团不仅赋予了其在紫外一可见光区有着独特的吸收区 (蓝光 区)， 因而其结晶或溶液在可见光下具有十分绚丽的红、 橙或黄色， 因浓度的不同， 显示出的颜色有一定的变化。类胡萝卜素长期被认为 是一类色素， 自然界中秋天的落叶和各种斑谰色彩的动物给人类以无 与伦比的美感。同时这些共轭双键还使得类胡萝卜素成为良好的自由 基猝灭剂， 具有很强的抗氧化活性， 能有效地阻断细胞内的链式自由 基反应， 从而具有多种独特而又重要的生理功能。 类胡萝卜素中最广泛而要重要的是 beta-胡萝卜素， 它是良好的 维生素 A原根据体内维生素 A量的多少， beta-胡萝卜素可自动分解 而补充维生素 A 的不足。 叶黄素和玉米黄质是同分异构体， 其唯一 的区别在于其中一个六元环端链上一个双键的位置不同，它们是唯一 存在于人类眼视网膜上的一种类胡萝卜素，它们选择性地沉积在黄斑 区和整个视网膜， 以黄斑的中心凹周围密度为最高， 视网膜周边部分 逐渐减少。 这些黄斑色素能有效地防止视网膜上面氧化反应的发生， 对视网膜有重要的保护作用。番茄红素对前列腺疾病的预防和治疗有 很好的作用。虾青素也有重要的抗肿瘤和预防癌症的作用等。这就是 为什么许多流行病学研究证实，经常和有规律地消费含类胡萝卜素的 水果和蔬菜可减少慢性疾病， 包括心血管疾病的危险， 同时具有预防 癌症的有益效果。
因此， 营养学家极力推荐添加、 预防性地摄取抗氧化剂维生素和 类胡萝卜素， 食物和药物市场因而为消费者提供大量此类"细胞保护 剂"。 目前市场上出现了各种各样的添加单一或多种类胡萝卜素的健 康食品，但人们补充类胡萝卜素更有效的方式是通过膳食补充剂的形 式摄入， 如各种片剂、 硬胶囊、 软胶囊等， 往往一粒片剂或胶囊就能 满足个人当天全部的类胡萝卜素需求量。 针对这些摄入方式的要求， 市场上也出现了多种类胡萝卜素剂型，如适于直接压片或套硬胶囊的 富含 beta-胡萝卜素的微粒 CarolBeta®, CaroCare®, 富含叶黄素的微 粒 CarolGold®, FloraGlo®, 富含玉米黄质的微粒 CarolZea®, 富含 番茄红素的 Redivivo®等； 也有一些适于装填软胶囊的类胡萝卜素的 油悬液。通过软胶囊方式摄食类胡萝卜素是一种较为方便也是较为流 行的方法。制备软胶囊时用到的类胡萝卜素往往是以油悬浮液的形式 存在， 也就是将类胡萝卜素粉碎到一定的细度然后悬浮于植物油中， 这样类胡萝卜素油悬浮液的流动性就决定了生产过程操作的难易程 度， 我们已经有相关专利公开了降低类胡萝卜素油悬液粘度的方法。
另一方面很重要的一点就是类胡萝卜素油悬液中有效成分颗粒粒 径的大小直接决定了以此油悬液为原料的软胶囊在人体中生物利用 度的高低，类胡萝卜素颗粒粒径越小意味着其被人体摄入后越容易被 吸收利用， 也就是拥有更高的生物利用度， 所以人们总是努力降低油 悬液中类胡萝卜素颗粒径， 让其达到微米级甚至纳米级， 以利于其被 装填入软胶囊后有较高的生物利用度。
而且， 通过软胶囊形式摄食类胡萝卜素时一个重要的因素就是不 能带入过多有害的有机溶剂，这就要求在类胡萝卜素被装填成软胶囊 前有尽量少的步骤接触到有机溶剂，并且有一定的步骤去除在加工过 程中带入的有机溶剂， 从而使其满足人类食用时安全方面的要求。
在先前文献中存在着多种制备类胡萝卜素油悬液的方法。 一般的 方法是将类胡萝卜素晶体进行充分地研磨，再将此研磨后的类胡萝卜 素微粉与植物油充分混合得到油悬浮液，但用此方法时一方面不可能 将类胡萝卜素晶体研磨得很细， 其粒径一般在 15μιη左右， 最终会影 响到用此油悬浮液制成的软胶囊在人体中的吸收利用，生物利用度较 差，另一方面在研磨地过程中不可避免地导致类胡萝卜素晶体温度升 高， 尤其是要将类胡萝卜素颗粒粒径研磨得很细时， 这种升温现象就 更明显，温度的升高必然会引起类胡萝卜素这种很容易被氧化的物质 降解损失， 所以通过研磨方法制备类胡萝卜素油悬浮液并不可取。
而 US6,936，279 Β2中揭示了一种方法制备类胡萝卜素油悬浮液， 其中先将类胡萝卜素与某种非水溶性溶剂混合，再与植物油混合后在 氮气流作用下雾化， 收集雾化后的溶液， 回收其中溶剂， 便得到类胡 萝卜素油悬液。在此过程中， 为了保证雾化后的类胡萝卜素颗粒不再 重新聚集， 要额外加入许多量的乳化剂和水， 而且为了去除大量的有 机溶剂，在收集一定量雾化后的"浓缩液"后要停下雾化操作而进行溶 剂回收， 这在工业化生产上是不利的， 此方法产量不大， 只适于实验 室规模。而且， 防止雾滴中类胡萝卜素晶体重新聚集的措施并不十分 有效， 终产品油悬浮中类胡萝卜素晶体颗粒粒径较大， 更重要的是， 雾化时大量乳化剂的存在对有机溶剂的完全去除是十分不利的，这必 然会给最终产品软胶囊的使用安全性带来隐患。同时没有有效的后续 操作去除这些对油悬浮液制备无任何价值的乳化剂，造成浪费和增加 了安全风险。
本发明中力图找到一种方法制备有较高生物利用度的类胡萝卜素 油悬浮液。此工艺路线中得到的油悬浮液中类胡萝卜素颗粒很细， 平 均颗粒粒径一般小于 5μηι， 易于被人体吸收利用，得到的产品中有机 溶剂几乎没有残留， 有很好的安全性， 而且此工艺有较高的工业化生 产效率， 适于连续化操作。
发明内容
本发明的目的是利用一种高效的方法方便地得到一种类胡萝卜 素油悬浮液，在此工艺中不需要额外的过程来超微粉碎类胡萝卜素晶 体， 而是直接将类胡萝卜素溶解于有机溶剂后喷雾于植物油中， 在此 过程中同时将类胡萝卜素溶液中有机溶剂在真空状态下去除，有机溶 剂的挥发使类胡萝卜素以无定型形式析出， 在高速搅拌的情况下， 析 出的类胡萝卜素晶体不会重新聚集而使其粒径变大，这样就能保证在 最终油悬浮液中类胡萝卜素颗粒足够细， 有利于人体吸收利用， 从而 具有较高的生物利用度。
根据本发明的一方面，本发明提供了一种制备类胡萝卜素油悬浮 液的方法， 所述方法包括如下步骤：
a) 将类胡萝卜素与有机溶剂混合， 加热使其完全溶解， 得到类 胡萝卜素溶液； 最好， 步骤 a)中加热温度为 40°C〜6(TC ;
b) 将步骤 a)中所述类胡萝卜素溶液以雾化方式进入高速搅拌的 植物油溶液中， 并同时在真空环境中回收雾化时产生的有机溶剂， 雾 化完成后有机溶剂同时回收完成， 得到类胡萝卜素油悬浮液；
其中， 所述类胡萝卜素油悬浮液含有颗粒平均粒径小于 5μιη的 类胡萝卜素晶体。

本发明中揭示的工艺适于工业化规模连续操作， 生产效率高， 没 有额外的研磨类胡萝卜素晶体的过程，降低了制备油悬浮液过程中类 胡萝卜素的降解。在雾化类胡萝卜素晶体过程中同时真空回收可重复 使用的有机溶剂， 而不需要专门的步骤去除有机溶剂残留。在雾化类 胡萝卜素晶体溶液过程中保持油 /类胡萝卜素 /有机溶剂混合液高速搅 拌状态， 可防止析出的类胡萝卜无定型晶体重新聚集， 从而能保证终 产品油悬浮液中类胡萝卜素颗粒粒径很小， 平均粒径一般小于 5μπι。 附图说明
图 1表示类胡萝卜素油悬浮液的制备过程简图。 具体实施方式
本发明的优点可以通过以下实施例来体现，但本发明的优点并不 仅限于这些实施例。
如图 1所示， 本发明的具体工艺说明如下：
先将类胡萝卜素晶体与一定比例的有机溶剂混合，加热使其完全 溶解， 再将此类胡萝卜素溶液从反应釜 R1底部通过高速旋转的喷头 雾化后进入植物油中，此植物油中可以包含了一定的抗氧化剂如生育 酚、 天然混合生育酚、 BHT、 抗坏血酸棕榈酸酯等， 重要的是， 在雾 化过程中，高速搅拌能有效地防止析出的无定型类胡萝卜素晶体重新 聚集而使其粒径变粗。 在此过程中， R1 反应釜处于真空状态， 一方 面能使喷雾后的有机溶剂及时挥发回收，另一方面有利于类胡萝卜素 晶体能以无定型形式及时析出。 有机溶剂通过两级冷凝器 E1 和 E2 后回收于贮罐 V01和 V02中， 可以循环使用。
工艺中用到的有机溶剂可以是水溶性的， 如丙酮、 四氢呋喃、 乙 醇、 异丙醇等， 也可以是非水溶性的， 如二氯甲垸、 甲苯、 乙酸乙酯 等。根据类胡萝卜素晶体在有机溶剂中溶解度的大小， 有机溶剂与晶 体的比例可以调节， 只要求类胡萝卜素能完全溶解于所述的溶剂中。
工艺中的植物油根据生产要求的不同可以是葵花籽油、 大豆油、 菜籽油、 玉米油、 花生油、 红花油等其它任何一种可供食用的植物油 类或它们的混合物。 根据最终油悬浮液中要求达到的类胡萝卜素浓 度， 反应釜中植物油与类胡萝卜素晶体的质量比例可以进行调节。而 且根据需要， 可以将部分植物油放置于反应釜 R1中， 另一部分与有 机溶剂和类胡萝卜素晶体混合溶解。在某些情况下， 特别是要求终产 品油悬液中类胡萝卜素含量较高时， 为了减少反应釜 R1中溶液的粘 度， 可以在植物油中混合一定量的其它有机溶剂， 对这些有机溶剂， 要求其毒性低，而且沸点比用来溶解类胡萝卜素晶体的有机溶剂的沸 点高， 这样在雾化过程中， 通过控制反应釜 R1夹套温度， 就可以让 用来溶解类胡萝卜素晶体的有机溶剂在真空状态下连续地去除，但用 于降低溶液粘度的有机溶剂还不会或很少被带走， 雾化完成后， 再升 高反应釜 R1夹套温度， 真空状态下回收这些有机溶剂。 适合于此类 的有机溶剂有乙醇、 异丙醇、 乙酸异丁酯等。最终产品中油悬浮液中 类胡萝卜素有效浓度依生产需要可进行调节， 可在 5%至 50%之间。
本发明中提到的类胡萝卜素包括所有工业化生产适于人类食 用、包括天然和合成来源的各种类胡萝卜素，如 β-胡萝卜素、叶黄素、 番茄红素、 角黄素、 玉米黄质、 虾青素等或者它们的混合物。 实施例 1
