Definitions
- the present invention comprises a process for the isolation of oils and / or fats with a specific oil or fatty acid spectrum from cells and / or biomass, and oils, fats and oil mixtures obtainable according to this process.
- Biologically produced in cells products often have to be laboriously isolated. For this it is necessary to destroy the cells. This can be done in different ways. Methods of cell disruption described in the prior art are e.g. chemical or biological treatment, exposure to osmotic pressure, freezing and thawing, ultrasound, freeze dispersion, pressing, wet milling in stirred ball mills or high pressure homogenization (S. Schultz et al., High Pressure Homogenization as a Method of Emulsion Preparation, Chem. Ing. 7), 901-909).
- the fluid to be disrupted is forced through a narrow gap at high pressure. Due to the low gap height according to the law of Bernoulli a very high speed and a very low pressure are reached. Due to the abruptly building up high energy density, the pressure drop and the resulting cavitation, the cell membrane is damaged.
- the disadvantage of this method is that, in addition to the desired destruction of the cell membranes, it also leads to an undesirable stabilization of the resulting emulsion due to the fine distribution of oil droplets in the continuous aqueous phase.
- the homogenized broth contains finely divided cell components, which is why one speaks of a suspo-emulsion.
- the cell components can additionally exert a stabilizing effect on the emulsion.
- an emulsion is stabilized by water-soluble salts of fatty acids or proteins, both of which are to be expected in the fermentation broth.
- PUFAs polyunsaturated fatty acids
- oil-containing material is an oil-containing biomass or oil, which means oil for humans and / or animals edible oil.
- oil-containing biomass By mixing two or more different oil-containing biomass in any proportions can be obtained by skillful selection of biomass, or the corresponding oil compositions of the biomass, almost all desired specific oil or fatty acid spectra.
- Preferred are e.g. Mixtures of omega-3 DHA-containing and omega-6 arachidonic acid (ARA) -containing biomass, e.g. from Ulkenia spec. and Mortierella alpina, optionally with the addition of further oil-containing biomasses.
- ARA arachidonic acid
- biomass or cell material may be extracted from one or more sources together with the addition of further oils.
- biomass (s) and the other oils, as well as the ratios used many desired oil compositions can also be obtained in one step.
- biomasses or cells with a high PUFA content are added with an excess of oils having a lower PUFA content extracted, whereby a stabilization (protection against oxidation) of the PUFA takes place.
- oils are, in particular, vegetable oils such as sunflower oil, olive oil, palm oil, thistle oil, borage oil, evening primrose oil, corn oil, soybean oil, linseed oil, rapeseed oil, but also animal oils, such as fish oil, krill oil, etc., as well as fractionated oils on this basis, and any further oil mixtures.
- Palm olein fractionated palm oil
- Palm olein contains a mixture of PUFA, monounsaturated and saturated fatty acids.
- the relative composition is about 44% oleic acid, 10% linoleic acid, 40% palmitic acid and 5% stearic acid.
- DHA and ARA-containing biomass is in the ratio of 5: 1 to 1: 5 (based on ARA or DHA content) with an up to twenty-fold excess of vegetable or animal oils, such as sunflower oil. Olive oil, palm olein oil, fish oil etc. extracted.
- the demulsification according to the invention can be carried out mechanically, physically, (electro-) chemically or by any combination of these demulsification methods.
- the mechanical demulsification is preferably carried out by means of centrifugation
- the mechanical demulsification preferably takes place in a temperature range of 0-
- the physical demulsification is preferably carried out by physisorbtion or extraction of the resulting suspo-emulsion with one or more linear, cyclic or aromatic hydrocarbons, e.g. Propane, hexane, cyclohexane or toluene.
- a particularly preferred solvent is hexane.
- the physical demulsification is preferably carried out in a temperature range of 0- 100 0 C.
- the electrochemical demulsification is preferably carried out by means of electrocoagulation or electrophoresis.
- the chemical demulsification is preferably carried out by chemisorption, addition of electrolyte or a surface-active auxiliary.
- Preferred is the chemical demulsification by means of a surfactant, more preferably with a fatty alcohol ethoxylate, in particular with Thethylenglycolmonodecylether.
- the surfactant according to the invention is used in a concentration of up to 25 g / l, preferably of 10-20 g / l and particularly preferably of 20 g / l.
- the chemical demulsification is preferably carried out in a temperature range of 0- 100 0 C.
- the invention further includes oils obtainable according to the process of the invention.
- these oils contain omega-3 and / or omega-6 fatty acids, e.g. Docosahexaenoic acid (DHA), docosapentaenoic acid (DPA), eicosapentaenoic acid (EPA), alphalinolenic acid (ALA), arachidonic acid (ARA), gamma-linolenic acid (GLA), dihomogammalinolenic acid (DHGLA), linolenic acid (LA), or mixtures of said fatty acids.
- Tab. 1 shows an example of a DHA rich oil according to the present invention. Mixtures of one or more of said omega-3 and / or omega-6 fatty acids with saturated or monounsaturated fatty acids form a further preferred embodiment.
- the oil obtainable by the process according to the invention is characterized by a particularly high quality, which manifests itself in a peroxide value of ⁇ 5 meq / kg and an anisidine value of ⁇ 30, compared with the oil produced by means of the processes known in the prior art.
- microorganisms which are suitable for obtaining PUFA.
- These microorganisms can be found, for example, in the bacteria under the genus WMo (for example: Vibrio marinus) or under the dinoflagellates (Dinophyta), there in particular the genus Crypthecodinium, such as C. cohnii or under the stramenopiles, such as the Pinguiophyceae such as Glossomastix , Phaeomonas, Pinguiochrysis, Pinguiococcus and Polydochrysis.
- WMo for example: Vibrio marinus
- Dinophyta dinoflagellates
- the genus Crypthecodinium such as C. cohnii or under the stramenopiles
- Pinguiophyceae such as Glossomastix , Phaeomonas, Pinguiochrysis, Pinguiococcus and Polydochrysis.
- Preferred microorganisms for the fermentative production of PUFA belong to the Stramenopiles (or Labyrinthulomycota), in particular to the order Thraustochytriales, (Thraustchytriidea) and there especially to the genera Japonochytrium, Schizochytrium, Thraustochytrium, Althornia, Labyrinthuloides, Aplanochytrium and Ulkenia, and Zygomycetes such as Mortierella alpina, Mortierella elongata or other species, Pythium insidiosum, Pythium irregular or other species.
- Aqueous fermentation broth with DHA-containing ulkenia (strain SAM2179) Biomass (oil content about 50%, DHA content in the oil about 44%) was with ARA-containing biomass (Mortierella alpina, oil content about 55%, ARA content in the oil about 40%) in the ratio 1: 1 (in each case based on biomass dry weight content) continuously fed to a high pressure homogenizer (eg APV 2000).
- the high-pressure homogenization can take place in one or two stages, wherein the pressure of the last stage is chosen so high that the majority of the cells is destroyed.
- the pressure of the high-pressure homogenizer necessary for the above fermentation broth for the quantitative digestion of the cells was at least 60 MPa.
