Abstract

The invention discloses a CO2 supercritical extraction method of sunflower disc nutrition ingredients, which relates to a sunflower disc nutrition ingredient extraction method. The method comprises the following steps: (1) crushing: cleaning fresh and disease-free sunflower discs, and crushing the sunflower discs to 40-80 meshes in a crusher; (2) drying: drying the crushed sunflower discs till the moisture content is 10-15%; (3) extracting: putting the dried sunflower discs into a CO2 supercritical extraction charging bucket, and adding a carrying agent to carry out CO2 supercritical extraction at the extraction pressure of 10-32 MPa and the temperature of 20-60DEG C to finally obtain extracting solution, wherein the flow of CO2 is 20-25kg / h. When the method disclosed by the invention is used for extracting nutrition ingredients from the sunflower discs, the range of extracted ingredients is wide and the purity is high.

Description

technical field [0001] The invention relates to a method for extracting nutrients from sunflower disks, in particular to a CO 2 A method for supercritical extraction of nutrients from sunflower discs. Background technique [0002] As a traditional Chinese medicine, sunflower disc has the effects of clearing heat, calming the liver and relieving pain, especially for high blood pressure, headache and tinnitus. At present, the research and extraction of nutrients in sunflower disc have attracted more and more attention. [0003] Sunflower discs are rich in nutrients, containing 7-9% of various amino acids, 6.5-10.5% of crude fat, and 2.4-3% of pectin. There is no effective method for extracting the nutrients of sunflower discs. Contents of the invention [0004] The object of the present invention is to provide a CO 2 A method for supercritical extraction of nutrients from sunflower discs. [0005] a CO 2 The method for supercritically extracting the nutrient components o...
