Title: Extraction of Sweat Potato Leaf Protein Concentrates by Fermentation Acid Method
Abstract: [Objective] The extraction processes of sweat potato leaf pretein concentrates were optimized.[Method] Sweat potato leaf protein concentrates were extracted by method of fermentation acid.Influence of fermentation acid and juice volume ratio,settling time and circle times of fermentation acid on the effect of extraction rate of leaf protein concentrates were first learned by the single factor experiment,and then the best technological parameter was determined by the orthogonal test.[Result]The result showed that the extraction rate of raw protein could reach to 63.28% and the extraction rate of leaf protein concentrates could reach to 52.57%.The optimal extraction parameter were showed as following:fermentation acid and juice volume ratio was 3∶1,settling time was 20 min and circle times of fermentation acid were one time.[Conclusion] These primary research results might provide the theoretic basis for the industrial extraction of leaf protein concentrates and its application in food nanotechnology.
