微藻中蛋白质的提取方法研究进展

Research progress on extraction methods of proteins from microalgae

微藻是一种光合自养型单细胞水生生物,能够合成脂质、蛋白质等多种活性成分。微藻中的蛋白质含量丰富,且具有较高的营养特性,能够调节机体健康、预防和治疗疾病等,在食品、医药、化妆品等领域具有广阔的发展前景。微藻蛋白质提取的关键在于细胞壁的高效裂解,从而使细胞中的蛋白充分释放。因此,该文基于常见的微藻细胞壁破壁技术,对微藻蛋白质的提取方法进行对比分析。旨在探索破壁更高效、过程更经济、易于工业化、蛋白更优质的提取方法,为微藻蛋白质的进一步开发利用,增加其商业价值提供指导。

Microalgae are photosynthetic autotrophic single-celled aquatic organisms,which can synthesize lipids,proteins,astaxanthin,and other bioactive components.Microalgae are rich in protein with high nutritional properties that can regulate body health,prevent and treat diseases,etc.,and have broad development prospects in food,medicine,cosmetics,and other fields.The key to protein extraction from microalgae is the efficient lysis of its cell wall,aiming at releasing the protein in the microalgae cell fully.Therefore,based on the common microalgae cell wall disruption technology,the extraction methods of microalgae protein were compared and analyzed systematically.The purpose of this study was to explore the extraction methods of microalgae protein,which were easier to industrialize,had higher wall-breaking efficiency and more economical process,and obtained protein with better quality.It is expected to guide the further development and utilization of microalgae protein,as well as increase its commercial value.
