Definitions
- the present invention relates to a method for the recovery or enrichment of flavors and / or fragrances from an aroma-laden gas or vapor phase that arises as a by-product during the thermal treatment of a vegetable or animal food, a method for the production of an aroma concentrate Eluate enriched with a flavor and / or fragrance or an aroma concentrate and / or fragrance concentrate, producible according to the method according to the invention, the use of such an enriched eluate or such an aroma concentrate and / or fragrance concentrate as well as products that contain the enriched eluate according to the invention or the aroma concentrate according to the invention and / or fragrance concentrate.
- volatile, flavors and / or fragrances are transferred into the gas or vapor phase.
- Such gas or vapor phases with valuable flavors and / or fragrances arise, for example, when drying plant-based foods, such as tea, fruit, vegetables, herbs, spices, flowers, when concentrating, for example, juices, in the production of Fruit preparations, when roasting plant-based foods such as nuts, coffee or cocoa beans, grain, malt, when cooking or roasting meat, etc.
- Methods for the recovery or enrichment or concentration of flavors and / or fragrances from an aqueous aroma phase include, for example, distillation, membrane processes, adsorption processes, extraction with supercritical carbon dioxide or liquid-liquid extraction.
- a disadvantage of the distillation process is that despite the use of gentle process parameters such as the use of vacuum to reduce the vapor pressures from the volatile components at temperatures of> 30 ° C, disturbing taste or fragrance components can be formed or desired taste or Fragrance components can be broken down. So During the distillation, for example, the thermal load on the aqueous aroma phase can result in undesirable cooking notes, which means that these methods of concentration can only be used to a limited extent, as they do not lead to an authentic taste profile.
- aromatic aqueous solutions are not a chemically uniform substance, but are made up of a large number of different chemical components which only in their entirety give the sensory result of the natural aroma of a food.
- the processes for recovery or enrichment known in the prior art often lead to an undesired fractionation of the mixture of the flavors and / or fragrances.
- the adsorptive enrichment or concentration of flavors and / or fragrances from an aroma-laden aqueous phase is described, for example, in EP 2 075 321 A1.
- the aqueous aroma phase is passed through an adsorption column and the flavor and / or fragrance substances absorbed on the adsorption material are desorbed by means of a solvent.
- the aim of the present invention was therefore to provide a method in which valuable flavors and / or fragrances directly from the gas or vapor phase with fewer losses or even without losses of the valuable taste and / or odorous substances, and without Degradation or modification of the taste and / or odorous substances, and thus can be recovered or enriched or concentrated while largely maintaining their original composition without additional expenditure of energy. Furthermore, the condensation apparatuses which are customary in the prior art and which are connected upstream of the adsorption columns should be avoided, since their acquisition costs are high.
- the present invention relates to a method for the recovery or enrichment of one or more flavor and / or fragrance (s), consisting of or comprising the following steps in this order:
- step (1 c) passing the aroma-laden gas or vapor phase from step (1 a) through the adsorption device with the adsorption material from step (1 b), so that the at least one flavor and / or fragrance is adsorbed on the adsorption material;
- the present invention relates to a method for
- step (2c) passing the aroma-laden gas or vapor phase from step (2a) through the adsorption device with adsorption material from step (2b), so that the at least one flavor and / or fragrance is adsorbed on the adsorption material;
- Another object of the present invention relates to an eluate, enriched with the at least one flavor and / or fragrance, or an aroma and / or fragrance concentrate, which can be produced by the above inventive method.
- Another aspect of the present invention relates to the use of the enriched eluate or the aroma and / or fragrance concentrate for flavoring or for reconstituting the aroma of food, luxury foods, beverage products, semi-finished products, oral hygiene products, cosmetics, pharmaceutical products or animal foods or for the production of food, luxury foods, beverage products, semi-finished products, oral hygiene products, cosmetics, pharmaceutical products or animal feeds.
- the present invention relates to food, luxury goods, beverage products, semi-finished products, oral hygiene products, cosmetics, pharmaceutical products or animal foods which comprise the enriched eluate or the aroma and / or fragrance concentrate.
- the combination of direct application of an aroma-laden gas or vapor phase, during or immediately after its generation, on the adsorption device and adsorption on a sorbent and subsequent desorption the aforementioned difficulties of the prior Technology can be solved and the valuable flavors and / or fragrances can be enriched without the need for an additional condensation step.
- the direct application of the gas or vapor phase to the adsorption device also enables flavors and / or fragrances, in particular volatile flavors and / or fragrances, to be absorbed more quickly, ie without a time delay, and better on the adsorption material, so that no oxidation can take place and thus losses of valuable flavors and / or fragrances can occur, which usually leads to a change in the sensory profile.
- FIG. 1 is a diagram which shows the content of aroma substances in the adsorptive enrichment from an aroma-laden gas phase according to the invention and from an aroma-laden condensate phase according to the prior art.
- Figure 2 is a diagram showing the content of flavoring substances, the content of which is ⁇ 300ppm, in the adsorptive enrichment from an aroma-laden gas phase according to the invention and from an aroma-laden condensate phase according to the prior art.
- Figure 3 is a diagram showing the amount of condensate over time as a function of the humidity of the drying air in the method according to the invention.
- FIG. 4 is a diagram which shows the content of aromatic substances as a function of the humidity of the drying air in the method according to the invention.
- the point is used as a decimal separator.
- a first object of the present invention relates to a method for
- step (1 c) passing the aroma-laden gas or vapor phase from step (1 a) through the adsorption device with the adsorption material from step (1 b), so that the at least one flavor and / or fragrance is adsorbed on the adsorption material;
- the present invention relates in a second aspect to a method for
- step (2c) passing the aroma-laden gas or vapor phase from step (2a) through the adsorption device with adsorption material from step (2b), so that the at least one flavor and / or fragrance is adsorbed on the adsorption material;
- process steps (1 a) to (1 e) of the process for the recovery or enrichment of one or more flavors and / or fragrances correspond or are identical to these.

- Gas is a substance that from its usual, mostly liquid state of aggregation has changed into a usually invisible gaseous state.
- Vapor is a gas that is generally still in contact with the liquid phase from which it emerged through evaporation. This is a visible moist haze, i.e. a visible mixture of air and the finest liquid droplets, such as is formed, for example, when water vapor condenses, also known as an aerosol. Both terms “gas phase” and “vapor phase” are used equally alongside one another in the present invention.
- Gas or vapor phases occur on a not inconsiderable scale in the production or processing of food, for example in thermal treatment, for example in drying, concentration, roasting, cooking or frying, in which / which predominantly evaporates water and / or is evaporated and not inconsiderable amounts, in particular highly volatile, flavors and / or fragrances pass into the vapor phase.
- the aim of the thermal treatment is to process or refine the food, ie the starting product or the main product, as gently as possible with maximum retention of all ingredients, for example to make the food edible, to change the taste or the shelf life to improve, etc ..
- Food in the context of the present invention are substances or products that are consumed in order to nourish the human body are ingested by humans for the purpose of nutrition or enjoyment through the mouth, possibly after further preparation.
- foods can be classified according to ingredients, origin, processing methods, reason for consumption, need for cooling.
- a common type of classification divides food according to the origin of the raw material into animal, vegetable and other products.
- Products of vegetable origin are vegetables, potatoes, legumes, fruit, algae, bread and baked goods, dry cereal products: flour, nutrients (rice, starch, semolina, pearl barley), pasta, vegetable oils and fats such as margarine, confectionery ( Jam, chocolate, syrup, sugar), spices, briquettes and snacks.

- an aroma-laden gas or vapor phase is further preferred, which arises during the drying of mushrooms and algae.
- thermal treatment is understood to mean drying.
- the drying of food is one of the oldest preservation processes for food and is well known to those skilled in the art. Drying is based on the principle of using suitable processes to remove the water from the food to such an extent that bacteria, molds and yeasts are deprived of their death, for example by lowering the aw value or water activity, and chemical reactions are prevented.
- industrial drying processes a distinction is made between conventional and special processes, and depending on the pressure conditions prevailing in the dryer, a distinction is made between normal pressure or vacuum drying.
- the conventional methods work with heated air, which can come into contact with the material to be dried in various ways. With fixed-bed drying, the warm air sweeps over the goods in tray, belt or tunnel dryers from above. With the more effective fluidized bed drying (fluidized bed drying), smaller-sized goods are flowed through by the drying air from below and whirled up in the process.
- the drying of the vegetable food in the method according to the invention according to the first and second aspect of the invention in a heat pump dryer, in particular at a temperature of 10 to max. 30 ° C, a heating cabinet, an infrared dryer, a convection oven or carried out in a convection heating oven.
- a heat pump dryer in particular at a temperature of 10 to max. 30 ° C, a heating cabinet, an infrared dryer, a convection oven or carried out in a convection heating oven.
- Such drying devices consist of a chamber with a loading and unloading device and allow drying in a closed system. This type of drying prevents aromas that sublime during the drying process from disappearing.
- the gas or vapor phase which is formed during the drying process and contains valuable aromas of the food to be dried, can be continuously removed, captured, collected and fed to further processing to recover the aromas.
- the above-described starting material is used at a temperature in a range from 20 ° C to 95 ° C, more preferably at a Temperature in the range of 40 ° C to 60 ° C and most preferably at a temperature in the range of 45 ° C to 55 ° C.
- drying process is carried out at higher temperatures, more valuable flavors and / or fragrances get into the gas or vapor phase, which creates an aromatic gas or vapor phase. If the drying process is carried out at low temperatures, more valuable flavors and / or fragrances remain in the plant-based food to be dried. If the drying process is carried out at a temperature higher than 70 ° C, there is a risk that thermal degradation reactions will result in a significant decrease in the yield of flavoring substances, both in the vegetable foods and in the gas or vapor phase.
- the large-scale drying of the vegetable foods is carried out with hot air at a temperature in the range from 70 to 120 ° C, preferably at a temperature in the range from 80 to 110 ° C and most preferably at a temperature in the range from 90 to 100 ° C.
- the air is directed over the dry material.
- the drying temperature depends heavily on the nature and condition of the starting material; For example, a sensitive raw material to be dried requires gentler temperatures for drying than a robust raw material to be dried.
- the drying temperature is therefore usually selected so that the dry goods, i.e. the main product, are as gentle as possible while retaining all of the ingredients as much as possible.
- air is used for drying, which has an absolute humidity of 0 to 50%.
- the moisture content of the air for drying is 0%.
- the moisture or water content of the dry air has no significant influence on the yield and the composition of the aromatic substances and / or Fragrance-enriched eluate.
- the plant foods can be dried in an inert atmosphere by applying an inert gas, preferably nitrogen gas. Drying in an inert atmosphere has the advantage that there is no oxidation and thus no loss of valuable aromas and fragrances.
- the drying time depends primarily on the amount and the moisture or water content of the food or starting product to be dried.
- the maximum duration is a maximum of 48 hours, preferably 10 to 15 hours drying.
- the drying process removes moisture from the vegetable food up to a content of about 5 to 30% by weight, in particular 20% by weight.
- thermo treatment is also understood to mean the concentration of plant-based foods, for example when evaporating juices to produce a fruit juice or vegetable concentrate.
- the juice ingredients are concentrated by separating the corresponding amount of water, e.g. from 12 to 70% dry matter.
- the term “thermal treatment” is also understood to mean the roasting of plant-based foods.
- Roasting is the heating of plant-based foods without adding any liquid in order to remove moisture from them, to change their taste, to color them darker or to increase their shelf life because of the moisture removal.
- the food is heated to up to 300 ° C, creating strong tasting aromas and bitter substances.
- Roasting is considered one of the basic types of preparation of Food. For example, nuts, kernels (sunflower seeds, pistachios and others), coffee and cocoa beans, grain, malt, chickpeas, onions, etc. are roasted.
- an aroma-laden gas or vapor phase that arises when roasting the plant foods described above is further preferred.
- thermo treatment is also understood to mean the cooking of vegetable or animal foods, in particular meat. Cooking means that food is cooked by heating it to at least 100 ° C, especially in water.
- thermo treatment is also understood to mean the frying of plant-based or animal-based foods. Roasting is dry cooking over high heat. The Maillard reaction creates compounds of proteins, fats and sugars on the surface of the food, which are responsible for the browning and the typical taste.
- an aroma-laden gas or vapor phase which is produced by cooking or roasting meat is further preferred.
- aromaa load as used in the context of the present invention, is to be understood broadly and means that the gas or vapor phase comprises at least one flavor and / or one fragrance.
- aromaa store thus equally includes a flavor and / or a fragrance.
- aroma store also includes a single flavor or fragrance or multiple flavors or fragrances or combinations thereof, or an aroma or fragrance that is found in the food, preferably in the plant, from which the gas or vapor phase is generated.
- the combination of a flavor and / or fragrance can comprise any number, i.e. two, three, four, five or even many more flavors and / or fragrances.
- At least one flavor or fragrance means in the context of the present invention that the gas or vapor phase either a single flavor and / or fragrance or a plurality, ie two, three, four, five or even far more, different tastes and / or Can comprise fragrance components, depending on the composition of the starting material from which the gas or vapor phase is generated.
- aromas or fragrances in foods or plants are not present in binary or ternary mixtures, but as a component of sophisticated, complex mixtures that contain two, three, four, five, ten, but preferably a much higher number of aroma or Can contain fragrances, sometimes in very small quantities, in order to produce a particularly rounded aroma or fragrance profile.
- the gas or vapor phase therefore comprises one or any large number Flavor or fragrance (s) selected from the group formed by: (1) hydrocarbons; (2) aliphatic alcohols; (3) aliphatic aldehydes and their acetals; (4) aliphatic ketones and their oximes; (5) aliphatic sulfur-containing compounds; (6) aliphatic nitriles; (7) esters of aliphatic carboxylic acids; (8) acyclic terpene alcohols; (9) acyclic terpene aldehydes and ketones; (10) cyclic terpene alcohols; (11) cyclic terpene aldehydes and ketones; (12) cyclic alcohols; (13) cycloaliphatic alcohols; (14) cyclic and cycloaliphatic ethers; (15) cyclic and macrocyclic ketones; (16)
