摘要
磷脂是一种天然的表面活性剂,在食品、医药、化妆品等方面有广泛的应用。详细介绍了高纯度粉末磷脂制备工艺中干燥过程的研究进展。总结了真空干燥、超临界二氧化碳干燥、真空冷冻干燥、振动流化床干燥等六种干燥高纯粉末磷脂的方法进展,并提出了超临界二氧化碳干燥和真空冷冻干燥两种有效的高纯粉末磷脂干燥方法。
Soybean phospholipids were widely used as an nature emulsifier in food, cosmetics, and pharmaceuticals industries. This paper reviews drying technology for high-pure powder soybean phosphohpids in details. All kinds of drying methods for high-pure powder soybean phospholipids were evaluated and some examples were presented. Three effective drying methods include supercritical CO2 drying, vacuum freeze drying and inert gas protected spray drying for high-pure powder soybean phospholipids were also suggested.
