Functional properties of seabuckthorn seed meal protein

Seabuckthorn seed meal protein was prepared by alkaline extraction and acid precipitation from seabuckthorn seed meal,and its solubility,water and oil holding capacity,emulsifying activity and foaming activity were studied.The results showed that functional properties of seabuckthorn seed meal protein were affected by environmental factors,such as pH,extraction temperature,ionic concentration of salt,ect.All the indexes of functional properties at isoelectric point of pH 5.0 were the lowest.
