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 [0001] The invention relates to a method for extracting tartary buckwheat nutrients, in particular to a CO 2 A method for supercritical extraction of tartary buckwheat nutrients. Background technique [0002] Tartary buckwheat is a medicinal and edible crop, which can soothe the nerves, activate qi and blood, lower qi and widen the intestines, clear away heat, swelling and pain, dispel accumulation and stagnation, clear the intestines, moisturize the intestines, laxative, relieve cough, relieve asthma, anti-inflammatory, Anti-allergic, cardiotonic, weight loss, beauty and other effects. [0003] Tartary buckwheat is a crop that integrates seven major nutrients, including bioflavonoids, trace elements and minerals, starch, vitamins, cellulose, fat, and protein. In addition, tartary buckwheat also contains chlorophyll that other food crops do not have. [0004] The current extraction method of tartary buckwheat nutrients has the defects of narrow extraction r...
