Definitions
- the present invention relates to a process for extracting organic products from plant or animal matrices, or their extracts, by high pressure extraction using conventional liquid solvents and in the presence of small amounts of supercritical fluids.
- JP 02235997 Preparation of algae aromas by extraction with supercritical or semi-critical carbon dioxide in the presence of water or alcohol
- US 4675198 Extraction of aromas from plant products using liquid or supercritical extractors
- JP 62036178 Extraction and separation of organic compounds from grape skins
- DE 2737794 Decaffeination of coffee by extraction with a solvent
- DE 2638383 Elimination of caffeine from coffee
- the process object of the present invention contemplates the maceration at pressures between 50 and 500 bar of the starting material in a solvent such as water, a hydrocarbon, an alcohol, a ketone, an ether, a carbon halide, or a mixture. of them, containing a supercritical fluid (FSC) in a proportion less than 50% of the total.
- a solvent such as water, a hydrocarbon, an alcohol, a ketone, an ether, a carbon halide, or a mixture. of them, containing a supercritical fluid (FSC) in a proportion less than 50% of the total.
- FSC supercritical fluid
- the high working pressure causes the penetrability of the FSC, as it decreases its viscosity and increases its diffusivity. This increase in diffusivity and decrease in viscosity facilitates the mobility of the FSC inside the cells and allows the extraction of substances much faster and with greater quantitative yields than in conventional extractions or in other existing extraction patents until moment.
- thermolabile products In addition to the extraction in an atmosphere that prevents oxidation, it is also carried out at such moderate temperatures, slightly higher than room temperature, that the risk of decomposition of thermolabile products is drastically reduced.
- the extraction mechanism is that the product extracted by the FSC is quickly solvated with the conventional solvent, establishing a balance between conventional solute-FSC-solvent that allows the
- the main solvent is not an FSC but it is ethanol, water or other solvents, which are those that are found in greater proportions, the FSC does not act as a solvent but acts as a transport vehicle between the plant matrix and the solvent
- extractions can be applied to the extraction of organic products such as essential oils, dyes, alkaloids, lipids, oils, waxes, proteins, fatty acids, aromas, spices, isoprenoids, steroids, carotenes, or pharmaceutical active ingredients, present in , or from, extracts of those provided by the technique, such as an oleoresin or an adsorbate, either present in, or from, biological matrices such as orange peel, paprika, grape skins, coffee, tea, plants Medicinal, seeds, carrot, or fish viscera.
- SUBSTITUTE SHEET (RULE 26) The time required to carry out this operation is generally between 0.5 and 5 hours.
- the product extracted and dissolved in the solvent is collected after depressurization and this technique can be combined with a separating stage that allows the extract to be recovered or fractionated. This recovery or fractionation can be carried out by any process offered by the technique.
- Example 1 Extraction of oleoresin from paprika. 140 g of paprika powder, 320 g of ethanol and 60 g of CO 2 are contacted for 30 minutes at 250 bar and 40 ° C. The extract is concentrated by evaporation in vacuo. 42 g of oleoresin are obtained.
- Example 2 Extraction of malvidin from the skins of the grapes. 100 g of grape skin, 280 g of ethanol and 150 g of CO 2 are contacted for 30 minutes at 150 bar and 80 ° C. The extract is concentrated by evaporation in vacuo. 125 mg of malvidin are obtained, approximately 70% of the total. This extract has a very aromatic character, which shows that the aromas present in the skin are also recovered during the extraction, i
- Example 3 Extraction of the essential oil, carotenes and flavonoids from the orange peel.
- 150 g of dried orange peel, 250 g of ethanol and 20 g of CO 2 are contacted for 30 minutes at 50 bar and 70 ° C.
- the extract is concentrated by evaporation in vacuo.
- 9 g of oleoresin are obtained, composed of the carotenes and flavonoids of the orange peel together with some pectins, free of degradation products, very aromatic and stable.
- Example 5 Extraction of pectins from orange albedo. 100 g of dry and finely ground albedo, 350 g of water acidified with nitric acid up to pH 2, and 40 g of CO 2 are contacted for one hour at 280 bar and 80 ° C. The extract is concentrated by evaporation under vacuum . To the residue after evaporation of water, ethanol is added, whereby 1.3 g of pectins precipitate.
- Example 6 Oil extraction from fishmeal. 200 g of fishmeal, 170 g of hexane, and 60 g of CO 2 are contacted for one hour at 250 bar and 50 ° C. The extract is concentrated by evaporation under vacuum. 13 g of oil are obtained.
- composition of this oil is: 6% in myristic acid, 19% in palmitic acid, 7% in palmitoleic acid, 19% in oleic acid, 8% in EPA, 8% in DHA, 12% in an unidentified fatty acid ( due to lack of standard), another 12% in another unidentified fatty acid (due to lack of standard), and the remaining 9% formed by miristoleic, pentadecanoic, stearic, heptadecanoic, linoleic and linolenic acids, in addition 1,209 ppm of vitamin A, 122 ppm of vitamin E, and small amounts of other vitamins.
- Example 7 Recovery of oil adsorbed by bleaching earth used in the refining of said oil. 200 g of one are contacted
- SUBSTITUTE SHEET (RULE 26) material whose composition is that of 76 g of adsorption land, 40 g of moisture, and 84 g of adsorbed olive oil, with 100 g of hexane and 40 g of C0 2 for 30 minutes at 280 bar and 40 ° C. extract is concentrated by evaporation in vacuo. 68 g of food grade olive oil are obtained.
- Example 8 Extraction of rosemary essential oil. 100 g of dehydrated rosemary, 200 g of hexane, and 60 g of CO 2 are contacted for 30 minutes at 150 bar and 40 ° C. The extract is concentrated by evaporation under vacuum. 5.7 g of oil are obtained.
- Example 9 Extraction of rosemary antioxidants. 100 g of dehydrated rosemary, 200 g of water, and 60 g of CO 2 are contacted for 30 minutes at 150 bar and 40 ° C. The extract is concentrated by evaporation under vacuum. 5.5 g of water-soluble extract are obtained.
- Example 10 Extraction of the essential oil and oleoresin from the rhizome of Turmeric longa. 125 g of Curcuma longa rhizome, 450 g of azeotropic ethanol, and 100 g of CO 2 are contacted for 30 minutes at 250 bar and 45 ° C. The extract is concentrated by evaporation under vacuum. 6.4 g of oleoresin are obtained, which contains 2.9 g of curcumin, equivalent to 46% of the curcumin present in the initial rhizome.
