Extraction and functional propeties of lupin protein
The protein from liupin was extracted by alkali-solution and acid-isolation and the optimal conditions are established as follows：pH 9.9,the ratio of solvent to meal 15.7,temperature 55.5 ℃ and 30.4 min.Under these conditions,the extraction yield was 13.13%.Four fractions of lupin proteins were separated by Osborne method,among which the protein content of albumin was the highest.Some functional properties of the protein,including the solubility,water-and oil-holding capacities,and emulsifying activity,were deter-mined.
