Abstract
The invention discloses a CO2 supercritical extraction method for tartary buckwheat nutrient, and relates to a method for extracting the nutritional components of tartary buckwheat. The CO2 supercritical extraction method for the tartary buckwheat nutrient comprises the following steps of: (1) crushing: putting the cleaned tartary buckwheat into a crusher and crushing; (2) drying: drying the crushed tartary buckwheat till the water content is 5 to 12 percent; and (3) extracting: filling the crushed and dried tartarybuckwheat into a CO2 supercritical extraction tank, adding edible alcohol serving as an entraining agent, and performing CO2 supercritical extraction to obtain an extract, wherein the extraction pressure is 20 to 32MPa, the extraction temperature is 30 to 40 DEG C, the flow rate of CO2 is 20 to 25kg/h and the extraction time is 1.5 to 2.5 hours. By using the method for extracting the tartary buckwheat, the extracted components are extensive and are high in purity.
Description
Technical field
The present invention relates to a kind of method for distilling of bitter-buckwheat nutritive thing, particularly a kind of CO
2The method of means of supercritical extraction bitter-buckwheat nutritive thing.
Background technology
Bitter buckwheat is a kind of medicine-food two-purpose crop, can calm the nerves, lively atmosphere blood, the wide intestines of sending down abnormally ascending, the swollen wind pain of heat-clearing, long-pendingization of dispelling are stagnant, gut purge, ease constipation, defaecation, cough-relieving, relieving asthma, effects such as anti-inflammatory, antiallergy, cardiac stimulant, fat-reducing, beauty treatment.
Bitter buckwheat is a kind of crop that integrates seven major nutrient, comprises bioflavonoid, trace element and mineral matter, starch, vitamin, cellulose, fat, protein, and in addition, bitter buckwheat also contains the chlorophyll that other cereal crops do not possess.
To the method for distilling of bitter-buckwheat nutritive thing, exist and extract narrow range, the defective that recovery rate is low at present.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of above-mentioned prior art, and a kind of CO is provided
2The method of means of supercritical extraction bitter-buckwheat nutritive thing.
A kind of CO
2The method of means of supercritical extraction bitter-buckwheat nutritive thing comprises the steps:
(1) fragmentation: buckwheat is cleaned back input disintegrating machine carry out fragmentation;
(2) oven dry: the bitter buckwheat after the fragmentation is dried, and making water content is 5-12%;
(3) extract: the CO that packs into of the bitter buckwheat after the fragmentation oven dry
2In the supercritical extract batch can, add and carry the agent edible alcohol, carry out CO
2Supercritical extract, extracting pressure are 20～32 MPa, and temperature is 30～40 ℃, CO
2Flow be 20-25kg/h, the extraction time is 1.5-2.5 hour, extracts and promptly to get extract.
The invention discloses supercritical CO ↓ ［ 2 ］ extracting process of a kind of tartary buckwheat bran oil: earlier with the tartary buckwheat bran low temperature drying, making water content is 5%～7%, the wheat bran of screening Φ 0.3mm～0.5mm; The wheat bran that above-mentioned screening obtains is put in supercritical CO ↓ ［ 2 ］ extraction kettle; Extraction kettle pressure is 21～23MPa; Extraction temperature is 36～38 ℃; The extraction time is 105～120min, and the first separating still separating pressure is set to 8.0MPa, and separation temperature is set to 35 ℃; The second separating still separating pressure is set to 5.0MPa, and separation temperature is set to 25 ℃; Carbon dioxide flow is controlled to be 20L/h～23L/h; From first separating still, collect extract, weigh, can obtain tartary buckwheat bran oil, the highest extraction yield is 87.49%.
Utilize that the inventive method has efficiently, reliable, safety, free of contamination advantage; Can the various nutritional labelings in the bitter buckwheat be extracted; The extraction composition is wide, and purity is high, and is easy and simple to handle; Product is limpid, no solvent residue, oxidation resistance are strong, the preparation of bitter buckwheat oil in suitability for industrialized production and the scientific research.
