Research on Processing Technology of Functional Zinc-rich Spirulina platensis

Abstract

Abstract: The research compared the capacity of biosorption in Zn2+ of the live Spirulina with that of the dead Spirulina and powdery Spirulina. The effects of different pH and concentration of Zn2+ and Spirulina on the biosorption of the powdery Spirulina for Zn2+ were also studied. The results showed that the capacity of biosorption in Zn2+ of powdery Spirulina is higher than that of the live and dead Spirulina. The highest biosorption of powdery Spirulina in Zn2+ is 50% when the concentration of Zn2+ is 0.06g/L and powdery Spirulina 1g/L in liquor at pH6. This research establish an academic basis for heightening the nutritional value and the economic value of Spirulina platensis.

Key words: Spirulina platensis, zinc, zinc-rich
