Embodiment 1
[0028] The seed coats of 10 tons of milk thistle seeds are removed by shelling machines, and the seed coats are collected to obtain 4.5 tons of seed coats. After 15 minutes of ultraviolet irradiation, the seed coats are put into the enzymatic reaction tank, softened by steam at 100°C for 20 minutes, and the water content of the material is discharged. About 8%, lower the temperature to 25°C, add 1.5% raw material weight of cellulase: pectinase: alkaline protease (5:4:1) compound enzyme, run the agitator, and enzymatically hydrolyze for 40 minutes. Move the enzymatically hydrolyzed raw materials into the material grid of the horizontal extractor, the charging amount is 70-80% of the material grid, the extraction temperature is 25°C, the rotation speed is 1r / 60-120min, spray continuously with absolute ethanol Drenched, extracted for 3 hours to obtain the extract; the extract was concentrated to 10m 3 Afterwards, the solvent was evaporated by vacuum drying, washed with 8 times th...
Embodiment 2
[0030] The seed coats of 25 tons of milk thistle seeds are removed by shelling machine, and the seed coats are collected to obtain 9.5 tons of seed coats. After 20 minutes of ultraviolet irradiation, the seed coats are put into the enzymatic reaction tank, softened by steam at 110°C for 15 minutes, and the water content of the material is discharged. About 9%, lower the temperature to 30°C, add 2.0% raw material weight of cellulase: pectinase: alkaline protease (5:4:1) compound enzyme, run the agitator, and enzymolyze for 30 minutes. Move the enzymatically hydrolyzed raw material into the material grid of the horizontal extractor, the loading amount is 70-80% of the material grid, the extraction temperature is 30°C, the rotation speed is 1r / 60-120min, spray continuously with absolute ethanol Drenched and extracted for 5 hours to obtain the extract; the extract was concentrated to 10m 3 Afterwards, the solvent was evaporated by vacuum drying, and washed with 6 times of water to...
