精确调整工艺参数
物质的结构和生物活性意味着必须使用非常特定的介质条件。提取工序特别适用于这种情况，但仍必须进行精确的调整，使其适应工艺参数，例如 pH 值、温度、浓度和有价值物质的精密结构。植物制药产品的功效还取决于植物提取物是否有适当和一致的剂量，因此行业标准非常重要。
浸渍还是渗滤？
植物提取物被定义为浓缩的液体、固体或粘稠物质的制剂。它们通常是通过浸渍（使用水或酒精提取到平衡状态）或渗滤（使用水或酒精提取到耗尽状态）获得的。生产中的关键因素是选择提取剂。水溶性（亲水）成分可以使用水来提取，而脂溶性（亲油）成分是使用酒精或其他溶剂从植物的特定部分提取的。
提取与常用工序的比较
与竞争性分离工艺（例如蒸馏、浓缩和膜技术）相比，提取在工艺技术方面显示了更高的效率，有更多的选择性，并且成本更低，适合无数种应用。它不仅极为温和，而且节约能源。
典型的植物提取工序
保健品和制药行业中使用的 GEA 提取卧螺离心机和精制分离机覆盖所有生产过程和模式：可实现液体对液体提取，也可以实现液体对液体对固体提取和液体对固体提取，无论是在一个阶段中还是在同时执行的多个阶段中，无论是逆流原理还是错流原理，都可以进行提取。流程图显示了典型的植物提取工序。
