Embodiment 2

[0032] The method for measuring flavonoid content and microencapsulation efficiency in the clathrate in embodiment 2 is:

[0033] Determination of the content of flavonoids on the surface of the clathrate: Accurately weigh a certain amount of clathrate, add absolute ethanol, fully shake and wash it, then set the volume to a certain volume, filter, and measure the flavonoid content according to the above-mentioned flavonoid content determination method.

[0034] Determination of total flavone content in clathrates: Accurately weigh a certain amount of clathrates, add 50% ethanol solution, oscillate and wash fully, set the volume to a certain volume, filter, and measure flavone content according to the flavone content determination method above.

[0035] Determination of microencapsulation efficiency: microencapsulation efficiency (%)=(1~product surface core material content / product core material content)×100

[0036] Experimental instrument, material used in embodiment 1,2 are ...

Embodiment 1

[0041]A1: Take 10g of tartary buckwheat powder, put it into a 250mL beaker, add cellulase for enzymolysis reaction, control the temperature of enzymolysis reaction at 52°C, pH value of 6.8, enzymolysis time of 90min, enzymolysis reaction mixture The concentration of cellulase is 2.5-2.8ul / L. After the enzymolysis reaction, add 150mL of 80% ethanol solution, extract by ultrasonic method, the extraction temperature is 60°C, and the ultrasonic time is 30min, then carry out vacuum filtration to obtain the filtrate and filter residue, extract the filter residue once more in the same way, and suction filter Finally, the two filtrates were combined, centrifuged and precipitated, and the supernatant liquid was rotary evaporated to 10-20 mL, then freeze-dried to obtain a dry powder, the extraction rate was calculated, and the flavonoid content was determined.

[0042] A2: Take 15g of tartary buckwheat flour, put it into a 250mL flask, add cellulase for enzymolysis reaction, control the...

Abstract

The invention discloses an embedding method of buckwheat flavonoids. The embedding method comprises the following steps of: crushing tartary buckwheat seeds; digesting and purifying to obtain buckwheat flavonoids; preparing a mixed solution through buckwheat flavonoids, an emulsifying agent and an embedding agent; performing oscillating, mixing and embedding reaction; uniformly mixing; leaching through filter paper; and drying the filter paper after leaching to obtain a buckwheat flavonoids inclusion, wherein the embedding agent comprises one of or both beta-cyclodextrin and maltodextrin. According to the embedding method of the buckwheat flavonoids, the buckwheat flavonoids in the prepared embedding compound are high in embedding rate, reaching 53.41 to 91.42%. According to the evaluation on indicator quality of a buckwheat flavonoids microcapsule product prepared by the embedding method, the dissolvability is more than 90%, the product is greyish white and contains a little yellow powder, and the microcapsule has the size of about 5 to 25mu g.

Description

technical field [0001] The invention relates to the field of extraction of tartary buckwheat components, in particular to an embedding method of tartary buckwheat flavonoids. Background technique [0002] Tartary buckwheat, the scientific name is Tatar buckwheat, which is produced in alpine mountainous areas and is planted in southwest my country and Shanxi and northern Shanxi. It belongs to Polygonaceae, an annual herb, 30-60 cm high. Stems erect, branched. The lower leaves are long-stalked, broadly triangular and halberd-shaped, entire or wavy; the lower leaves are smaller. Racemes axillary or projected, perianth white or pale pink. Nutlets conical-ovate, triangular, taupe. The flowering and fruiting period is from June to September. The seeds of tartary buckwheat can be eaten or used as fodder. The root and the whole herb can be used as medicine, which can dehumidify and relieve pain, detoxify and reduce swelling, strengthen the stomach, and treat bruises, waist and...
