Definitions
- the invention relates to a method for producing an aroma-laden gas, an aroma-laden gas, the use of the aroma-laden gas, in particular the use of aroma-laden carbon dioxide, and a method for aromatizing a product.
- CO2 carbon dioxide
- non-alcoholic beverages such as sparkling wines (sparkling wine), lemonades or beers.
- sparkling wines sparkling wine
- lemonades or beers This calls for the search for new manufacturing techniques that enable drinks or food to be produced not only with an enjoyable taste and a pleasant smell, but also completely without the use of ethanol.
- Such products are basically in the course of a healthier way of life and are particularly interesting for countries in which it is assumed that food is halal in accordance with religious regulations (Halal certificates).
- alcohol-free does not necessarily mean "without alcohol”.
- beer and wine advertised as “alcohol-free” may contain a maximum of 0.5% alcohol by volume. If another drink (than wine or beer) is advertised as “non-alcoholic", it must actually contain no alcohol at all, the alcohol content is therefore 0.0% by volume, otherwise the label "alcohol-free” is viewed as misleading and deceiving consumers.
- a supercritical fluid has properties of both gas and liquid. In this supercritical state, such a fluid or gas, for example C02, functions as a solvent.
- Supercritical carbon dioxide has a density very similar to the density of a liquid, but has the same viscosity as a gas. This results in higher diffusion coefficients than in the liquid phase and thus higher mass transport. It can dissolve or extract materials in a sample.
- solid phase extraction is a sample preparation method with regard to a possible enrichment, concentration or isolation of an analyte.
- SPE solid phase extraction
- a liquid phase is extracted from a solid phase (sorbent).
- the fractionation of a tomato extract using a solid phase extraction is mentioned, for example, in EP 2844083 B1.
- EP 3063260 describes a process for the extraction of two or more fractions from hop oil, in which the hop oil loaded on an adsorbent carrier is treated first with liquid carbon dioxide for the purpose of separating the first fraction and then with supercritical carbon dioxide for the purpose of separating the second fraction.
- the other fractions can be separated off when the supercritical carbon dioxide is combined with a co-solvent.
- EP 0062893 A1 discloses a method for producing plant extracts with improved sensory properties.
- the plant parts are first extracted with supercritical CO2, for example. Then the extracted plant ingredients are deposited on a powder or granulate carrier material. The residues of the plant parts are subjected to a second extraction with water and / or a monohydric Cl-C3 alcohol, the extract obtained being dried. The ones after the first and second Extraction obtained Products are combined by mixing.
- the object is therefore to find an improved method for producing an aroma-laden carbon dioxide which is suitable for introducing aroma / aroma mixtures into foods, cosmetic products and / or pharmaceutical products which can be labeled "without alcohol".
- Another object of the invention is to find a method which enables the flavoring substances to be "enriched” from very dilute starting solutions (which only contain traces of flavoring substances) in the end product, namely in the aroma-laden gas and, if necessary, to assemble various flavoring compositions in the end product.
- step (b) Passing through a solid phase extraction column (SPE column) the liquid phase provided in step (a) to obtain the one loaded with one or more aromatic substances solid phase (sorbent), optionally can step
- the method according to the invention even allows the flavoring substances to be extracted in a concentrated form from very dilute, preferably aqueous, starting solutions.
- the aroma substances are first adsorbed or concentrated on the solid phase of an SPE column and, with the help of a further extraction with supercritical and / or liquid gas, preferably with supercritical CO 2 , converted into the aroma-laden gas, which can be characterized as alcohol-free.
- Gas serves both as an extraction agent and as a carrier material for the aroma substances and can easily be removed from these aroma substances and, if necessary, recycled.
- Another advantage of the present process is that, thanks to the concentration of the aroma substances in the SPE column, much less gas and less energy is consumed during extraction with supercritical and / or liquid gas to obtain the same amount of aroma substances than during extraction with supercritical and / or liquid gas directly from a very dilute starting solution.
- the method according to the invention is therefore more environmentally friendly and, from an economic point of view, better optimized than the previously known methods for producing a flavor-containing carbon dioxide. In addition, no further materials are necessary to stabilize the manufactured product.
- liquid phase includes any starting solution, starting emulsion or starting suspension that meets the requirements for sample preparation for SPE.
- This starting solution, starting emulsion or starting suspension contains at least one solvent and one or more flavorings, both animal as well as of vegetable origin.
- the starting materials for the aromatic substances are selected from the group consisting of plants, plant parts (such as flowers, buds, leaves, stems, stalks, bark, roots, tubers, onions, rhizomes, fruits and seeds, for example from nuts, berries, fruit, Vegetables, grains, pseudo-grains, tobacco and / or spices), animal products (such as honey, meat, bones and body fluids, milk), foods and food raw materials.
- plant parts such as flowers, buds, leaves, stems, stalks, bark, roots, tubers, onions, rhizomes, fruits and seeds, for example from nuts, berries, fruit, Vegetables, grains, pseudo-grains, tobacco and / or spices
- animal products such as honey, meat, bones and body fluids, milk
- foods and food raw materials can, for example, be in fresh, cooked, dried, fermented form or in a form prepared for consumption as food or luxury goods.
- the liquid phase can be a condensate or rinse water, which arises in the processing of fruits or in the production of beverages such as fruit juices, coffee, tea and beer.
- the liquid phase can also be a drink itself and, for example, be selected from the group that includes fruit juices,
- the invention creates the possibility of obtaining flavorings from waste or bypass flows.
- One advantage of the invention is to enrich, by means of a preconcentration in the solid phase extraction column, the extremely low concentration of aroma substances in such “waste streams” or “side streams” at least to the extent that they can be extracted.
- Obtaining waste or bypass streams directly from such a starting material is generally not economically feasible due to the very low concentrations there, at least not without the use of ethanol or other organic solvents. Accordingly, recovery directly from such a starting material for waste or bypass streams is currently not possible economically and in food quality without the use of ethanol.
- the aqueous phases generally contain in the range from 0.0001 to 1%, frequently from 0.05 to 0.5%, flavoring substances. This can be illustrated using an example of juice extraction from apples with the following information:
- the proportion of aromatic oil of 0.3 kg based on 100 kg from the 2nd stage results in 0.3%. In relation to 1500 kg from the 1st stage, the result is 0.02%. In relation to the non-concentrated total condensate amount of 187,500 kg, this results in 0.00016%.
- the invention enables flavorings to be obtained from liquids, in particular from beverages and from "waste streams" such as condensates from evaporators or from water obtained in freeze-drying, or from rinse water from cleaning large industrial plants. Volatile substances are enriched. These are not fractionated , but in relation to the respective starting material as an entire "aroma portfolio". According to the invention, the starting concentration of the flavoring substance is not important; it can be as low as desired.
- the aroma substances according to the invention are concentrated and obtained without organic enrichment and therefore in particular free of ethanol.
- step b) is preferably carried out at room temperature, in particular without external heating.
- the separation with a gas in the liquid or supercritical state in step c) can also be carried out at relatively low temperatures, in the case of supercritical CO 2 for example already at 31 ° C.
- the invention By pre-concentrating all of the aromas of a starting material in step b), the invention enables a particularly environmentally friendly extraction of these aromas in step c), which saves a significant amount of solvent, i.e. gas in a liquid or supercritical state, compared to a pure extraction with such Gas allowed.
- solvent i.e. gas in a liquid or supercritical state
