Problems solved by technology

80% of the total lipids are free, which can be extracted by non-polar solvents such as n-hexane and ether; the remaining 20% ​​are bound lipids, which can be extracted by polar solvents. Therefore, a single solvent system cannot effectively extract oat lipids

Embodiment 1

[0030] 1. Weigh 20g of oat bran, put it into the reactor, add 240mL of n-hexane, soak it, put it into the microwave oven, connect the condensation reflux device, heat and extract intermittently under 100W microwave power for 240s, take it out and cool it to room temperature, Centrifuge under the condition of 30min / min, take the supernatant and evaporate in vacuum to obtain the crude oil of oat bran extracted by microwave-ultrasonic.

[0031] 2. Heat the crude oat bran oil to 60° C., add deionized water at the same temperature with an oil weight (mass) of 10%, stir for 30 minutes, cool to room temperature, and centrifuge to obtain degummed oat bran oil and colloid, that is, oat polar lipid.

[0032] 3. Take the degummed oat bran oil in an Erlenmeyer flask, add 1% glycerin of oil weight (mass) and mix evenly. After heating to 70°C, add 2% lipase Novozym 435 and mix evenly. Stir to start the esterification and deacidification reaction to obtain the deacidified oat bran oil.

Embodiment 2

[0034] 1. Weigh 40g of oat bran, put it into a reactor, add 240mL of n-hexane:ethanol (1:4), soak it, put it in a microwave oven, connect a condensing reflux device, and heat and extract it intermittently for 120s under 200W microwave power. Take it out and cool it down to room temperature, centrifuge at 4000r / min for 30min, take the supernatant and vacuum rotary evaporation to obtain the crude oil of oat bran extracted by microwave-ultrasonic.

[0035] 2. Heat the crude oat bran oil to 70° C., add deionized water at the same temperature with 5% oil weight (mass), stir for 30 minutes, cool to room temperature, and centrifuge to obtain degummed oat bran oil and colloid, that is, oat polar lipid.

[0036] 3. Take the degummed oat bran oil in an Erlenmeyer flask, add 5% glycerin of oil weight (mass) and mix evenly. After heating to 60°C, add 5% lipase Novozym 435 and mix evenly. Stir to start the esterification and deacidification reaction to obtain the deacidified oat bran oil. ...

Embodiment 3

[0038] 1. Weigh 60g of oat bran, put it into the reactor, add 240mL of ethanol, soak it, put it into the microwave oven, connect the condensation reflux device, heat and extract intermittently under 300W microwave power for 60s, take it out and cool it to room temperature, Centrifuge for 30 min under the condition of min, take the supernatant and vacuum rotary evaporation, and obtain the crude oil of oat bran extracted by microwave-ultrasonic.

[0039] 2. Heat the crude oat bran oil to 80° C., add deionized water at the same temperature with an oil weight (mass) of 3%, stir for 30 minutes, cool to room temperature, and centrifuge to obtain degummed oat bran oil and colloid, that is, oat polar lipid.

[0040] 3. Take the degummed oat bran oil in an Erlenmeyer flask, add glycerin with 10% oil weight (mass) and mix evenly. After heating to 50°C, add 10% lipase Novozym 435 and mix evenly. Stir to start the esterification and deacidification reaction to obtain the deacidified oat b...

Abstract

The invention discloses a method for extracting oat bran oil through a microwave-ultrasonic-assisted compound solvent. The method takes oat bran as a raw material, and comprises the following steps: firstly, extracting oat bran crude oil through the microwave-ultrasonic-assisted compound solvent; secondly, performing degumming on the oat bran crude oil, so as to obtain degummed oat bran oil and gum corresponding to oat polar lipid; thirdly, performing deacidification on the degummed oat bran oil, so as to obtain extracted oat bran oil. The method can rapidly and efficiently extract oat bran oil from the oat bran, and the oat bran oil extracted through the method further has high antioxidant activity and can serve as a raw material of anti-aging face cream.

Description

technical field [0001] The invention relates to the technical field of oil extraction, in particular to a microwave-ultrasonic assisted composite solvent extraction of oat bran oil using oat bran as a raw material and its full utilization method in cosmetics. Background technique [0002] Oat is a grass plant and one of the main crops in the world. It is rich in protein, dietary fiber, unsaturated fatty acids and other nutrients. Oat is not an oil crop, but compared with other grains, its fat content ranks first. The lipid content of oat often depends on its genetic traits and environmental factors. It is generally 2-12%, and more than 90% is distributed in bran and in the endosperm. Oat oil contains high-quality fatty acids, palmitic acid, oleic acid and linoleic acid account for more than 95% of the total fatty acid content, of which the unsaturated fatty acid content is about 80%. Unique efficacy. Oat oil is also rich in VE, phytic acid, phenols, sterols, avenanthramid...
