Embodiment 1
[0020] Get 500g of millet bran crude oil obtained by solvent leaching, the acid value is 9mgKOH / g, the content of vitamin E and oryzanol is 765mg / kg and 0.35% respectively, and the phospholipid content is 1.5%. Inject the crude oil into the refining device, seal and heat to 55°C, then evacuate to 0.086MPa vacuum degree, add 20% citric acid solution 2 g, after stirring for 3 minutes, add 3 g (0.4 times the phospholipid content in the oil) of hot water at 55°C, and stir for 35 minutes under a vacuum of 0.080 MPa; keep it for 5 hours under normal pressure, and remove the gum in the lower layer. Add ethanol-isopropanol extractant (ethanol:isopropanol = 9:1) with a pH value of 6.0 and a concentration of 85% to the degummed oil, vacuum extraction and deacidification twice at 35°C, and keep the vacuum degree at 0.078-0.080 MPa; the weight of the extractant added for each deacidification is 900 g, and the vacuum stirring time for each extraction is 30 min; after the stirring is comple...
Embodiment 2
[0022] Take CO 2 The crude millet bran oil obtained by supercritical extraction is 800g, the acid value is 14mgKOH / g, the contents of vitamin E and oryzanol are 883mg / kg and 0.42%, respectively, and the phospholipid content is 0.8%. Inject the crude millet bran oil into the vacuum refining device, heat it to 65°C and then evacuate it to 0.080 MPa, add 3.0 g of 20% citric acid solution, stir for 4 minutes, add 5.1 g (0.8 times the phospholipid content in the crude oil) ) of 65°C hot water, stirred for 20 minutes under a vacuum of 0.074MPa; after standing for 6 hours at normal pressure and heat preservation, the lower colloid was removed; the degummed crude oil was added with a pH value of 5.5 and a concentration of 9 5% ethanol-isopropanol extractant (ethanol: isopropanol = 12:1), extract and deacidify 3 times at 25°C and 0.080-0.082MPa vacuum, each time the weight of the extractant is 1200g; each time The extraction was stirred for 20 min, and after the extraction, it was lef...
