Embodiment 1

[0037] (1) Preparation of kettle bottle fragmented rice extract:

[0038] The dry bottle bottle is smashed with sieve, then add water to the rice bottle, rice powder, soaked for 80 min, the material is 1: 23, then heating, the ultrasound is 50 min at 60 ° C, ultrasonic frequency 40Hz The temperature is lowered to 40 ° C, then filtered, the filtrate adjusts pH to 6.5, add a certain proportion of lactic acid bacteria to ferment, fermentation time is 4.3 h, dried to reduce the rough macarin powder in the pot bottle.

[0039] (2) Decollection of the bottle fragmented rice extract:

[0040] The bottle bottle of the bottle plate (1) is dissolved in distilled water, and the weight volume ratio of the bottle bottle and the distilled water is 10: 300-g / ml, and 0.5% activated carbon, 1300R / min speed is stirred for 17 minutes, then the pH value of the tank bottle of the rice grain extract is filtered to the equal electricity point of the bottle of the rice grain protein, and then at 4 ° ...

Embodiment 2

[0048] (1) Preparation of kettle bottle fragmented rice extract:

[0049] The dried bottle bottle is smashed with sieve, then add water soaking into the pot bottle, the water is soaked for 60 min, the material is 1:30, then heating, the ultrasonic extraction of 60 min is extracted at 75 ° C, ultrasonic frequency 40Hz The temperature is lowered to 45 ° C, then filtered, the filtrate adjusts pH to 5.3, add a certain proportion of lactic acid bacteria to ferment, fermentation time is 4 h, filtrate under reduced temperature dry, to obtain a bottle grazing rice crude protein powder;

[0050] (2) Decollection of the bottle fragmented rice extract:

[0051] The bottle bottle of the bottle of step (1) is dissolved in distilled water, the weight volume ratio of the powder and distilled water of the bottle and the distilled water is 13: 500 g / ml, add 1.5% activated carbon, 900R / min Speed ​​is stirred for 15 minutes, then the pH is filtered into the hydraulic spin of the rice bottle of t...

Embodiment 3

[0059] (1) Preparation of kettle bottle fragmented rice extract:

[0060] The dried bottle bottle was pulverized, and then the water was added to the pot bottle of rice. The temperature is lowered to 45 ° C, then filtered, the filtrate adjusts pH to 5.2, add a certain proportion of lactic acid bacteria to ferment, fermentation time is 4 h, filtrate under reduced temperature, dry, to obtain a bottle barrel crude crude protein powder;

[0061] (2) Decollection of the bottle fragmented rice extract:

[0062] The powder prepared by step (1) is dissolved in distilled water, and the weight volume ratio of the bottle bottle and distilled water is 11: 650 g / ml, add 0.8% activated carbon, 900R / min. The speed is stirred for 25 minutes, then the pH of the tank bottle is filtered to the equal electricity point of the bottle of the rice grain protein, then stand for 13 hours, then centrifuge at 4 ° C, 5900r / min, and collect the precipitate and vacuum Frozen dry, gave a rough protein, a b...

Abstract

The invention discloses a preparation method for extracting, separating and purifying selenomethionine from cardamine hupingshanesis. The preparation method comprises the following steps: (1) preparing a cardamine hupingshanesis extract; (2) decolorizing the cardamine hupingshanesis extract; (3) grading and purifying cardamine hupingshanesis crude protein;(4) hydrolyzing the cardamine hupingshanesis crude protein; and (5) purifying and freeze-drying the hydrolyzed protein. the preparation method for extracting, separating and purifying selenomethionine from cardamine hupingshanesis can obviously improve the color and purity of the cardamine hupingshanesis extract, is advanced, scientific and convenient to operate, the selenomethionine in cardamine hupingshanesis has good antioxidant activity, the selenomethionine can be applied to preparation of health-care products with antioxidant and anti-aging effects, and the method provides favorable technical means and use value for market application of cardamine hupingshanensis, and has huge economic and social benefits.

Description

Technical field [0001] The present invention relates to the field of plant extract techniques, and more particularly to a method for extracting the purified purified selenine from a bar bottle. Background technique [0002] The pot bottle of rice is a cruciferous plant, and the bottle gravel rice is cultivated to reach a selenium. The selenium is more than 1000mg / kg, of which the organic selenium content accounts for about 93.30%, as a selection health care The addition of the product has high security, absorbing features, with great application space. [0003] At present, the spray drying product of the bottle bottle is dark brown, and the scope of its application is limited, so the extract must be decolorized. The extract of the activated carbon is well color state, which provides advantageous conditions for subsequent selenine purification. After the final product selenine was purified, the product was purified and the yield was good. Inventive content [0004] The preparat...
