Embodiment 1
[0014] 1. Degreasing and deodorizing treatment of corn yellow powder
[0015] Subjecting maize flour to supercritical CO 2 Fluid extraction, extraction pressure 10MPa, temperature 35°C, time 0.5 hours, CO 2 The flow rate is 15L / hour.
[0016] 2. Extraction of Zein
[0017] with supercritical CO 2 The maize flour after fluid extraction is used as a raw material, and the ethanol concentration is 60%, the mass ratio of maize flour and ethanol solution is 1:8, the extraction temperature is 50° C., and the pH value is 8.0. Extract for 2 hours to obtain a zein solution. Centrifuge the zein solution at a speed of 3000 rpm for 5 minutes to obtain a supernatant, dilute the supernatant with distilled water until the concentration of ethanol is 30% and when turbidity occurs, adjust the pH value to 6.5 with 4mol HCI solution, add A saturated sodium chloride solution with a total volume of 2% promotes the precipitation of prolamin, and centrifuges at a speed of 4000rpm for 5 minutes to...
