Abstract

The invention provides a preparation method of a buckwheat flavone microcapsule, which comprises the following steps: 1) pretreating: drying buckwheat grain, buckwheat shell, buckwheat husk or buckwheat stem leaf, sieving after crushing for standby to obtain buckwheat powder; 2) extracting; 3) separating and purifying; 4) preparing a capsule emulsion: uniformly mixing a core material, a wall material and an emulsifier to prepare a buckwheat flavone microcapsule emulsion; 5) spray drying to obtain the buckwheat flavone microcapsule. The invention has the advantages that: 1, the activity of an active component flavone substance in buckwheat is protected; 2, the buckwheat flavone is prevented from damage of gastric acid, has certain targeting after microencapsulation, and has good enteric solubility but insolublility in stomach; 3, the bitter taste of buckwheat is covered; 4, the release speed is controlled, the flavone substance can not be stored in vivo, and the concentration of the flavone substance is rapidly increased in vivo after taking and rapidly decreasing due to metabolism degradation effect, the microencapsulation enables a slow release function and releases functional factors in certain time and scope.

Description

【Technical field】 [0001] The invention relates to a preparation method of buckwheat flavonoid microcapsules and products thereof. 【Background technique】 [0002] Modern medical research has found that flavonoids are one of the important nutritional and health-care functional factors in buckwheat. They are ubiquitous in buckwheat kernels, shells, stems, leaves, and flowers. The main component is rutin, which accounts for 70% of the total flavonoids. 90%. [0003] Rutin has the function of regulating capillary permeability, can maintain capillary resistance, reduce its permeability and fragility, and has anti-inflammatory, diuretic, and blood lipid-lowering effects. It is clinically used as a capillary hemostatic drug. Adjuvant therapy for hypertension. Rutin is the main raw material for the preparation of hydroxyethyl rutin and rutin tablets in the pharmaceutical industry. Buckwheat is rich in resources. The seeds are mainly used as food, while the flowers and leaves are m...
