Example Embodiment
[0032] Example one:
[0033] 1. Dissolve 200 g of rapeseed oil deodorized distillate in 600 ml of acetone-methanol mixed solvent (the volume ratio of acetone and methanol is 3:1), and the amount of the mixed solvent is 3 ml / g vegetable oil deodorized distillate. Starting from 50°C, slowly lower the temperature and crystallize to -5°C. The crystallization time is 18h. The crude sterols are separated by suction and filtration. Repeat the above crystallization operation again for 4h. The filtrate is evaporated and concentrated under reduced pressure at 65°C for 45min to obtain a deodorizing distillate that removes sterols.物173g.
[0034]2. The deodorized distillate from which sterols are removed is subjected to molecular distillation operation, the distillation temperature is 220°C, the operating pressure is 0.01 torr, the feed temperature is 80°C, and the rotating speed is 150r / min to obtain distillate and residual liquid; distillate components It is a fatty acid / vitamin E / glyceride...
Example Embodiment
[0037] Embodiment two:
[0038] 1. Dissolve 200 g of rapeseed oil deodorized distillate in 800 ml of acetone-methanol mixed solvent (the volume ratio of acetone and methanol is 5:1), and the amount of the mixed solvent is 4 ml / g vegetable oil deodorized distillate. Starting from 60°C, slowly lower the temperature and crystallize to -5°C. The crystallization time is 24h. The crude sterols are separated by suction and filtration. Repeat the above crystallization operation again for 8h; the filtrate is concentrated by evaporation under reduced pressure at 65°C for 45min to obtain a deodorizing distillate for removing sterols.物180g.
[0039] 2. The deodorized distillate from which sterols have been removed is subjected to molecular distillation operation at a distillation temperature of 230°C, an operating pressure of 0.03torr, a feed temperature of 90°C, and a rotating speed of 180r / min to obtain distillate and residual liquid; distillate components It is a fatty acid / vitamin E / glyce...
Example Embodiment
[0042] Embodiment three:
[0043] 1. Take 200 g of soybean oil deodorized distillate and dissolve it in 700 ml of acetone-methanol mixed solvent (the volume ratio of acetone and methanol is 4:1). Starting from 60°C, slowly lower the temperature and crystallize to -5°C. The crystallization time is 20h. The crude sterols are separated by suction and filtration. Repeat the above crystallization operation again for 6h; the filtrate is concentrated by evaporation under reduced pressure at 65°C for 45min to obtain a deodorizing distillate for removing sterol物182g.
[0044] 2. The deodorized distillate from which sterols are removed is subjected to molecular distillation operation, the distillation temperature is 220°C, the operating pressure is 0.02torr, the feed temperature is 80°C, and the rotating speed is 150r / min to obtain the distillate and residual liquid; distillate components It is a fatty acid / vitamin E / glyceride concentrate, mainly containing fatty acids, vitamin E and glycer...
