With 60 mesh filter-cloth filterings after the distilled water of amount, filtering residue is crushed again up to Rhizoma Steudnerae Henryanae granularity completely below 60 mesh, obtains Rhizoma Steudnerae Henryanae serosity.
(2) acid is carried：A certain amount of purple sweet potato powder is taken, the solid-liquid ratio for comparing 1: 8～1: 10 with extracting solution weight according to purple sweet potato powder enters
Row ultrasound assisted extraction, extracting solution pH2.0, extraction time are 20～60min, obtain filtering residue and muddy filter with 100 mesh filter-cloth filterings
Liquid.Filtrate is centrifuged under 2000r/min, precipitate is dried at 40 DEG C -55 DEG C, that is, is obtained Crude starch；Or take Rhizoma Steudnerae Henryanae slurry
Liquid, plus appropriate citric acid control mixture pH for 2.0,20～60min of ultrasound assisted extraction time, with 100 mesh filter-cloth filterings, general
Filtrate is centrifuged under 2000r/min, precipitate is dried at 40 DEG C -55 DEG C, that is, obtains Crude starch.
(3) isoelectric precipitation：Gained filtering residue in (2) is dried at 70-85 DEG C and is smashed, that is, obtain insoluble meals fine
Dimension；Supernatant after centrifugation in (2) is concentrated in vacuo to into the 1/5～1/6 of original volume at 50 DEG C, then adjusts pH value of solution 4, stood
Overnight.The precipitate for obtaining is centrifuged under 4000r/min and is thick protein.
(4) precipitate with ethanol：The supernatant obtained after centrifugation in (3) is added into 95% ethanol of 4 times of volumes, is stood overnight, 100 mesh
Filter-cloth filtering, filter residue and drying obtain final product water soluble dietary fiber.
(5) concentrate：Filtrate in (4) is concentrated in vacuo to into the 1/5～1/6 of original volume at 50 DEG C, that is, obtains anthocyanidin dense
Contracting liquid.
Compared with prior art, present invention process scheme passes through simplicity, a continuous method so that purple sweet potato starch, flower
Blue or green element, protein, water soluble dietary fiber and insoluble dietary fiber are disposably efficiently extracted, and do not produce any adding
Work waste, the course of processing is without any pollution, and the protein for obtaining is non denatured, therefore, the comprehensive utilization to Rhizoma Dioscoreae esculentae
It is significant.
