Abstract
The rapeseed protein concentrate was prepared by alcohol extraction from rapeseed meal.The effects of extraction temperature,extraction times,volume fraction of alcohol and ratio of solvents on the protein content of rapeseed protein concentrate were examined.By single factor tests and orthogonal experiment,the optimal extraction conditions were determined as follows:extraction temperature 60℃,extraction times 6 times,ratio of solvents 9∶1,volume fraction of alcohol 80% and pH 4.0.Under the optimal conditions,the protein content of rapeseed protein concentrate was 65.96%,and the extraction rate was 71.54%.
