Embodiment 1

[0017] The method for extracting flavonoids from tartary buckwheat bran in the present embodiment comprises the following steps:

[0018] a. First, the tartary buckwheat grains are screened to remove impurities and then peeled off, then crushed and sieved to separate the flour and bran; according to the difference of tartary buckwheat raw materials, the bran yield is controlled at 10-15%;

[0019] b. Get 5kg of tartary buckwheat bran, control the moisture content of the bran at 10%, and then send the material into a single-screw extruder for processing. The extruding temperature is 150°C, and the screw speed is 300r / min; The extruded and expanded bran is fluffy and porous granular material; after microwave drying, the moisture content of the extruded and expanded bran material is lower than 8%, which is convenient for degreasing treatment or storage;

[0020] c. Degreasing the bran material after extrusion and puffing by solvent extraction;

[0021] d. the bran material after...

The extruding temperature is 140°C, and the screw speed is 280r / min; The extruded and expanded bran is fluffy and porous granular material; after microwave drying, the moisture content of the extruded and expanded bran material is lower than 8%, which is convenient for degreasing treatment or storage;

[0027] c. Degreasing the bran material after extrusion and puffing by solvent extraction;

[0028] D. the bran material afte...

Embodiment 3

[0031] The method for extracting flavonoids from tartary buckwheat bran in the present embodiment comprises the following steps:

[0032] a. First, the tartary buckwheat grains are screened to remove impurities and then peeled off, then crushed and sieved to separate the flour and bran; according to the difference of tartary buckwheat raw materials, the bran yield is controlled at 10-15%;

[0033] b. Take 10kg of tartary buckwheat bran, control the moisture content of the bran at 14%, and then send the material into a twin-screw extruder for processing. 100°C, 120°C, and 140°C respectively, and the screw speed is 200r / min; make the extruded and expanded bran a fluffy and porous granular material; Less than 8%, it is convenient for degreasing treatment or storage;

[0034] c. Degreasing the bran material after extrusion and puffing by solvent extraction;

[0035] d. the bran material after degreasing is 50% ethanol-water solution solvent with concentration, under the conditio...

Description

technical field [0001] The invention relates to a method for extracting flavonoids from tartary buckwheat bran, which belongs to a production method for extracting flavonoids. Background technique [0002] Tartary buckwheat is a unique and precious crop resource in my country. It is mainly produced in the central and western regions and has not been fully utilized for a long time. Studies have shown that tartary buckwheat is rich in bioflavonoids, D-chiro-inositol and other biologically active ingredients, which have the effects of anti-oxidation, softening blood vessels, preventing and treating diabetes, hypertension, hyperlipidemia and other cardiovascular diseases. The content of flavonoids in tartary buckwheat bran can reach more than 6%, which is an important raw material for extracting tartary buckwheat flavonoids. Because the flavonoids contained in tartary buckwheat bran exist in bran cells, the tough and dense bran cell wall is the main limiting factor for the extr...
