摘要
对花生磷脂的制取工艺进行研究,研制出高等级的花生磷脂产品。花生油的生产采用静电处理和冷冻过滤等工艺,得到质量较好的、不含水的毛磷脂胶质副产品,采用超临界萃取技术对毛磷脂进行提纯,利用二氧化碳在临界高压下对非极性的油类具有溶解性而对极性的磷脂难以溶解的特性,达到将磷脂从含油胶质中提取分离的目的。磷脂产品外观为淡黄色,磷脂质含量大于90%。
The preparation process of peanut phospholipid is studied, high grade peanut phospholipid product is developed. The peanut oil is produced by the technology of electrostatic treatment, freezing filtration and so on. The by-product, phospholipid colloid is good quality and unhydrous. Purified by supercritical extraction technology, using the characteristic of carbon dioxide solubility in the non-polar oils and difficult solubility in polar phospholipid, phospholipid is extracted and separated from oil colloid. The appearance of phospholipid product is light yellow, the content of phospholipid is more than 90%.
