Definitions
- the invention relates to a method in which soluble ingredients are obtained from organic raw materials by means of a supercritical gas and at pressures above 1100 bar up to 5000 bar, wherein the addition of entraining agents is completely omitted.
- Extraction of vegetable and animal raw materials are known and are usually operated by means of supercritical CO 2 as a solvent. It uses the fact that supercritical gas behaves almost analogously to a liquid and that there is a very good solubility of important substances in supercritical CO 2 . Very well known is the decaffeination of coffee.
- solubility of substances increases, inter alia, with the temperature and pressure. It is also known that at fixed temperature and increasing pressure, the solubility passes through a maximum. Increasing the pressure beyond the maximum degrades the solubility.
- WO 2006/05537 A1 describes an extraction process by means of CO 2 for the separation of caffeine from a tea plant.
- pressures of up to 1000 bar at temperatures of up to 80 0 C are proposed as process parameters.
- EP 1 424 385 B1 describes another process for the production of xanthohumol-enriched hops extract and its use. This process takes place at a pressure of up to a maximum of 1000 bar and temperatures above 60 ° C. Both of the abovementioned processes cite, as the limit for the pressure in the extraction stage, 1000 bar at comparable temperatures. The ideal range for the extraction is given below 1000 bar. This limit of 1000 bar described in WO 2006/05537 A1 and EP 1 424 385 B1 is identical to the physically determined range in which the solubility maximum of the raw material's own natural oils is in the supercritical CO 2 gas, the exact pressure depending on the respective temperature is.
- US 4,466,923 describes a method in which a lipid is extracted from a lipid-containing material by means of supercritical carbon dioxide, wherein the extraction in a pressure range of 55O 0 C to 1200 0 C is performed and by selecting pressure and temperature at least 5 % solubility of the supercritical carbon dioxide over the material to be extracted is adjusted.
- the problem arises that the different components have different solution behavior and that with increasing pressure and temperature the solubilities of one part of the components increase, while the solubilities of another part of the components, usually the more easily soluble, already decrease again ,
- the organic material is filled into one or more high-pressure vessels, sealed and then pressurized to more than 800 bar, below
- the filled high-pressure container is flowed through by the supercritical gas at least once, wherein the supercritical gas, no additional entraining agent is added, and then
- the laden supercritical gas is supplied in whole or in part to a separation stage in which natural substance or mixtures of substances are separated or separated from one another under pressure reduction, and • the pressure in the extraction stage exceeds the maximum solubility pressure of the raw material's own oil or fat in the supercritical gas by at least 10%, with the respective feedstock oil or fat acting as an entraining agent.
- the pressure in the extraction stage exceeds the maximum solubility of the raw material oil or fat in the supercritical gas by at least 10%, this pressure increase above the maximum solubility of the raw material oil or fat can also be significantly higher.
- CO 2 carbon dioxide
- the pressure is preferably in the range of 1100 bar to 5000 bar, ideally at 1300 bar to 2500 bar.
- the organic material in the high-pressure vessel of the extraction stage is repeatedly flowed through by the supercritical gas in a circulating stream.
- the temperature in the supercritical gas is changed before or in the separation stage by means of heat exchangers.
- the extraction process can be improved to the effect that in the first separator, which adjoins downstream of the extraction stage, there is a pressure which is in the range of maximum solubility of the crude oil or fat in CO 2 , and ideally at most 2% or below this solubility maximum.
- a pressure in this first separator is in the range of 800 bar to 1000 bar.
- An improved embodiment of the method provides that the extraction takes place in two stages. Before the extraction at the abovementioned pressures above 1100 bar, an extraction step is carried out in advance, in which a pressure is present which in the Range of maximum solubility of the raw material's own oil or fat in CO 2 , and ideally at most 2% above or below this maximum, that is, as in the first separator after the entire extraction.
- At least 2 and ideally 3 or 4 separators are provided in the separation stage, which have different pressure levels. By this grading, a preliminary separation of the extracted substance mixture can be achieved.
- hazelnut kernels were extracted at 4O 0 C and different pressures.
- a batch was extracted by the method according to the invention at 1500 bar and the same amount of nut cores in a comparative experiment with a method according to the prior art at 500 bar.
- the method according to the invention could be achieved in the same amount of CO 2 on the double yield of oil and alkaloids, while the proportion of oil and alkaloids increased almost parallel. It can also be ascertained from these experiments that high-pressure extraction by the process according to the invention is a thermally very gentle process.
- carotenes and carotenoids were also extracted and the yield together with capsanthin, capsorubin, beta-carotene, beta-criptoxanthin, lutein, violaxanthin and zeaxanthin totaled 8% and the oil yield was again 10%.
- the ratio of solvent to feed was 40, as above, based on their mass.
- a further comparative experiment 0.5 kg of hot pepper (Capsicum frutescens) was filled in an extractor and extracted at 2300 bar and 60 0 C for 2 hours. The ratio of solvent to feed was 35, based on their mass.
- a first separator which was operated at 1000 bar and 40 0 C, 18 g of a dark red, semi-solid product containing capsanthin, capsorubin, beta-carotene, beta-criptoxanthin, lutein, violaxanthin and zeaxanthin were deposited, resulting in a yield of 3.6% corresponds.
- the following separator which was operated at 300 bar and 4O 0 C, separated an emulsion of aromatic components and water.
- the solid residue still contained carotenes and carotenoids.
- the same amount of hot pepper was extracted at the same pressure and temperature, but at a ratio of solvent to feed of 17.5 initially and an extraction time of only one hour.
- a first separator a comparable product was deposited.
- the subsequent separator operated under the same conditions as above, an emulsion of aromatic components and water separated as well, but this emulsion was recompressed and returned to the high pressure extractor.
- carotenes and carotenoids were also extracted and the yield together with capsanthin, capsorubin, beta-carotene, beta-criptoxanthin, lutein, violaxanthin and zeaxanthin totaled 7%, the oil yield again 10%.
- the ratio of solvent to feed was 40, based on their mass.
