Description

一种从辅酶Q10发酵液中提取辅酶Q10的方法 技术领域
本发明涉及一种从类球红细菌发酵产生的辅酶Q10发酵液中提取辅酶Q10的方法，属于抗氧化剂提取技术领域。
背景技术
辅酶Q10是一种脂溶性抗氧化剂，能激活人体细胞和细胞能量的营养，具有提高人体免疫力、增强抗氧化、延缓衰老和增强人体活力等功能，医学上广泛用于心血管***疾病，国内外广泛将其用于营养保健品及食品添加剂。
目前，国内相关文献中对于辅酶Q10的提取纯化，通常采用陶瓷膜过滤工艺和层析工艺，这两种提取方法各具优缺。
例如，中国专利CN111153786A采用的是陶瓷膜过滤工艺，其工艺过程为：将辅酶Q10发酵液经过滤得到的菌粉，分别经浸提和蒸干得到辅酶Q10粗品，然后经过小孔径陶瓷膜过滤、碱化、皂化反应和陶瓷微滤膜进行过滤处理，陶瓷微滤膜的浓缩液减压蒸馏除溶剂之后，得到辅酶Q10。该方法存在的问题是：
①、该方法在提取纯化前未对辅酶Q10的发酵液进行预处理，导致粗品中的杂质含量较高，超过了40％以上，不利于下游提取纯化工艺的继续进行。
②、整个提取纯化工艺步骤较多，其中有2次膜过滤工序和皂化反应，导致提取周期较长，降低了生产效率。
③、膜过滤和皂化反应并没有有效解决辅酶Q10杂质含量高的问题，特别是成品中的色素问题，影响了产品的品质。
又如，中国专利CN108863743A采用层析的方法提取纯化辅酶Q10，其工艺过程为：采用的工艺是萃取、沉淀、脱色和层析精制步骤，该技术达到的技术效果是产品辅酶Q10的纯度可达到99.8％以上，总收率可达到98.5％以上，但是存在的问题有：
①、提取过程中，分别采用了吸附工艺和层析工艺相结合，导致提取周期较长，生产效率较低。
②、吸附工艺中吸附剂是活性白土、硅藻土和活性炭(至少一种)，影 响了产品的收率，使辅酶Q10收率下降了1～2％。
③、层析工艺中使用的吸附剂是硅胶。辅酶Q10吸附过程中，发现硅胶吸附剂存在比表面积小、吸附量低、吸附效率低、吸附效果差等情况。在大生产的条件下，硅胶吸附剂用量很大，而且吸附周期时间较长，收集到的辅酶Q10经检测，杂质含量较高，超过了2％。
④、该发明中实施例展现的规模较小，未能体现出工业化大生产达到的技术水平。依据该工艺进行了中试验证，菌渣的规模为50kg，进过三次提取和纯化，最终产品的平均收率在90～92％，纯度在93～95％，未能达到该专利所中阐述的技术水平。
再如，中国专利CN107337593A采用的工艺是：首先将辅酶Q10发酵液经陶瓷膜微滤和喷雾干燥得到粗品，然后将该粗品用丙酮浸提，所得浸提液分相、减压浓缩得到辅酶Q10提取浓缩液，之后用石油醚萃取、硅胶柱层析、减压蒸馏浓缩洗脱液，最后加入辅酶Q10晶种结晶，减压干燥即可得到辅酶Q10纯品。该技术存在的问题是：
①、该技术中没有阐述工艺的技术效果，而且产品提取收率低。五个实施例中，提取总收率在73～7％，总收率较低。
②、采用硅胶层析工艺，中国专利CN108863743A存在同样的问题。
中国专利CN106146278A公开了一种从菌渣中提取制备高纯度辅酶Q10的工艺，该技术以菌渣为原料进行渗漉提取得辅酶Q10渗漉提取液，将辅酶Q10提取液经多级萃取进行除杂得萃余液，再将萃余液进行结晶处理，最终得到辅酶Q10。众所周知，渗漉工艺就是动态的浸提工艺，该专利没有阐述辅酶Q10发酵液预处理工艺，其次菌渣中的脂溶性杂质可以通过渗漉工艺进入有机溶液；最后采用多级萃取除杂，只能去除大部分杂质，杂质去除量有限。
