- the focus of the present invention is to provide a process for producing an ethanol-free vanilla extract without the use of ethanol and to provide an ethanol-free vanilla extract having only traces of ethanol naturally contained in fermented vanilla pods and prepared without the use of ethanol.
- the vanilla is a spice that is obtained from the fermented capsule fruits of various species of the orchid genus Vanilla.
- the spice vanilla Vinilla planifolia
- the Tahiti vanilla Vanilla tahitensis
- the Guadeloupe vanilla Vanilla pompona
- vanilla planifolia The aroma of the dried and fermented pods of Vanilla planifolia, Vanilla tahitensis and Vanilla pompona is one of the highest quality and the world's most widely used flavors. It is used for the flavoring of numerous foods such as ice cream, dairy products, desserts, chocolate products, baked goods, spirits, etc.
- Vanilla pods contain on average about 1, 6 to 2.4% of the flavoring agent vanillin, which makes an important contribution to the flavor impression, in addition to other flavorings. Extracts from the above vanilla pods are preferred because of their complex and authentic flavor profile the vanillin based extract-free flavors.
- Fermented vanilla beans are extracted for decades with ethanol as extraction solvent.
- the extract thus obtained is subsequently concentrated by distillation. This process and storage-related changes of the sensory profile occur.
- vanilla extracts The odor impression of vanilla extracts is caused by more than 30 odorous substances such as capric acid, methyl cinnamate, guaiacol, 4-methyl guaiacol, ethyl linolenate, p-hydroxybenzoic acid, p-hydroxybenzaldehyde and vanillin (Perez-Silva et al., Food Chemistry 99 , 2006, 728-735).

- vanilla extract Since numerous secondary components that are not sensitive to the sensory, such as polysaccharides, waxes, fats in the extraction of fermented vanilla pods stabilization of the vanilla extract plays an important role. Normally, ethanol remains in the extract as a solvent after extraction and thus stabilizes waxes, fats and other lipophilic substances that would precipitate without the use of a solubilizer.
- vanilla extract dissolved in ethanol changes its sensory profile during storage and develops, for example, in the language of the expert, fruity, reminiscent of rum notes.
- WO 2006 047404 A2 discloses, for example, the fermentation of any plant starting material with a glucosidase, followed by an aqueous extraction in the presence of another reactant, for example an amino acid or a sugar. Both work neither teaches a teaching on the stabilization of the microbiologically unstable water extract nor a method for the concentration of the extract.

- the solid line describes the vanillin content of an extraction at 25 ° C
- the dotted line describes the vanillin content of an extraction at 65 ° C.
- ethanol-free vanilla extract is understood to mean a vanilla extract which, with the exception of traces of ethanol naturally present in fermented vanilla pods, has no ethanol and is prepared without the use of ethanol.
- fermented vanilla pods are provided in a first step.
- the vanilla pods are fermented vanilla pods of the genus Vanilla planifolia, Vanilla tahitensis and Vanilla pompona.
- the fermented vanilla pods are prepared as follows: Vanilla plants are grown in plantations. The up to 30 cm long vanilla pods, botanically correct are capsule fruits, are harvested shortly before maturity when they are yellowish-green. The green fruits do not have the typical flavor and taste of the finished product at harvest time.
- the fruits must first be subjected to fermentation. For this it is first necessary that the cells of the capsule fruits are lysed. This is done by conventional methods known in the art, for example by physical methods such as by treating the green vanilla pods with hot water or steam, freezing and thawing the green vanilla pods, by treating the green vanilla pods with CO2 under pressure or by enzymatic treatment of the green vanilla pods with cellulase, pectinases, etc. In this process step, on the one hand a release of glucovanillin, the precursor of vanillin, and on the other hand, a release of endogenously occurring in the green vanilla pods ⁇ -glucosidases.
- vanilla pods a fermentation and drying of the vanilla pods takes place during which they lose water and assume their typical dark brown color.
- the glucovanillin is converted into vanillin, the main flavoring agent of vanilla, by hydrolysis.
- the fermented vanilla beans thus produced usually have a moisture content of 10 to 30% and a vanillin content of 1 to 3%, based on the dry matter.
- the fermented vanilla pods described above, for use in the process of the present invention are then shredded into small pieces about 10 mm in size, for example cut, chopped, cut, by means of cutting mills or shredders known in the art and known to those skilled in the art shredded, crushed or chopped. By using crushed vanilla pods, the subsequent extraction is facilitated.
- the comminuted vanilla pod particles have a size of 1 to 10 mm.
- the vanilla pods are too pasty and make the subsequent process steps, such as filtration (clogging of the sieves) or distillation (bumping), more difficult.
- Pretreatment of the vanilla pods is not required in the process of the invention.
- vanilla pods bits are transferred, for example, in a Willmes press and to ensure circulation to the contact between the extraction material and the extraction solvent or extraction solvent mixture and thus to increase the efficiency of the extraction.
- an ethanol-free vanilla extract according to the present invention the use of ethanol having a log P value of -0.33 is excluded as extraction solvent as such or in an extraction solvent mixture of the aforementioned definition ,
- Extraction is a physical process in which a starting material, wholly or at the surface, is exposed for some time to the action of a liquid, such as water, oil or a solvent, which serves as a solvent for certain ingredients and which Extract ingredients from the solid.
- a liquid such as water, oil or a solvent
- the starting material is not dissolved as such, but only soluble constituents of which go into the solvent.
- the choice of solvent depends on their respective dissolving power with respect to the substance to be dissolved.
- logP logP
- C (n-octanol) is the concentration of the solvent in the n-octanol phase; and C (water) is the concentration of the solvent in the water phase.
- K (n-octanol / water) is a dimensionless distribution coefficient indicating the ratio of the concentration of the solvent in a two-phase system of n-octanol and water. It is thus a model measure of the polarity or water / fat solubility of the solvent.
- the log P value is a common physical parameter and is positive for lipophilic solvents and negative for hydrophilic solvents. Ultimately, the log P value of the extractant determines which flavorants are extracted qualitatively and quantitatively from the shredded vanilla bean particles.
- An extraction solvent mixture according to the present invention comprises at least one of the above-mentioned. organic extraction solvent in combination with another from the group of the above-mentioned organic extraction solvents.
- an extraction solvent mixture comprises at least one of the above-mentioned. organic extraction solvent in admixture with water.
- an extraction solvent mixture according to the present invention comprises at least one of the above-mentioned. organic extraction solvent in admixture with another organic solvent which is typically used as an ingredient of foods, for example vegetable oils, essential oils, sugar syrups, etc.
- vegetable oils are selected from the group consisting of sunflower, soybean, rapeseed , Peanut, palm, wheat germ, corn germ, olive and linseed oil.
- an extraction solvent mixture containing at least one of the o.g. organic extraction solvent is used, the mixing ratio of organic extraction solvent to another organic solvent in a range from 10: 90 (v / v) to 90: 10 (v / v), preferably in a ratio of 50 : 50 (v / v).
- the mixing ratio of organic extraction solvent to water is in a range of 90:10 (v / v) to 60:40 (v / v), preferably in a ratio of 80 : 20 (v / v).
- the above-mentioned extraction solvents are used neat. Surprisingly, it was found that the extraction of the comminuted vanilla pods in step (c) of the method according to the invention with acetone, which has a log P value - 0.24, with respect to the sensory relevant ingredients, ie the flavoring flavoring in the Particularly good results compared to the other above-mentioned extraction solvents.
- the ratio of the amount of extraction solvent or extraction solvent mixture to vanilla seed quantity used is important for exhaustive extraction.
- saturation of the extraction solvent or of the extraction / solvent mixture rapidly occurs, with the result that the valuable constituents from the comminuted vanilla pods can not be completely extracted.
- the extraction solvent or extraction solvent mixture is therefore used in the inventive method in excess of the amount of comminuted vanilla pods to ensure an exhaustive extraction.
- the extraction solvent mixture is added to the amount of shredded vanilla pods in a range of 1: 1 (w / w) to 40: 1 (w / w) used.
- the ratio of extraction solvent / extraction solvent mixture to the amount of shredded vanilla pods is 10: 1 (w / w).
- the extraction of the comminuted vanilla pods in the process of the invention is carried out in a defined time / temperature profile. Surprisingly, it has been found that in an extraction at room temperature, for example, sweet, malty-smelling flavors develop increasingly. With an extraction temperature at higher temperatures of about 65 ° C increases the solubility and thus the yield of the flavorings to be extracted, while at the same time arise dry fruit notes.
- the extraction of the crushed fermented vanilla pods is carried out in a temperature range of 20 to 60 ° C (preferably 30 to 60 ° C) for a period of 8 to 20 hours.
- Prolonged extraction time may result in the degradation of valuable ingredients, the formation of dry fruit notes, volatile carotenoid degradation products such as damascenones, and yield aldehydes, which in turn results in the distribution of the aroma components in the vanilla extract, and thus the Sensory profile of the vanilla extract influenced.
- the extraction is carried out at a temperature of 40 ° C for a total of 16 hours.
- the extraction of the comminuted vanilla pods is carried out in such a way that the extraction solvent or the extraction solvent mixture is renewed at least twice but not more than five times consecutively.
- the extraction solvent or the extraction / solvent mixture is renewed at least three times consecutively. Consecutive extraction ensures exhaustive extraction of the flavorings from the crushed vanilla pods, maximizing the yield of flavorings.
- the crude extract obtained is decanted from the extraction material and the fractions obtained from several consecutive extraction steps crude extracts are combined to form a crude extract.
- the extraction solvent or extraction solvent mixture used in the process according to the invention must be completely removed from the crude extract either for sensory reasons, for example due to a strong intrinsic odor, or due to regulatory requirements.
- acetone itself is an odorant with a threshold of 300 mg / kg, which adversely affects the sensory profile of the flavor extract produced with it with its fingernail-like odor.
- the European Union is calling for the removal of acetone to the technically unavoidable level, and the IOFI (International Organization for the Flavor Industry) even requires a limit of 2 mg / kg in the final application in its "Code of Practice". It is a set of rules that is used internationally in the flavor industry.
- ethanol is an odorant with a threshold of 1,000 mg / kg, which is not perceived olfactorily even at one percent by volume in the end-use application, and which may be used indefinitely in foods.
- a solvent having a boiling point which is preferably at least 20 ° C higher than the boiling point of the extraction solvent used in step (c) of the inventive method or at least one organic Extraction solvent in the extraction solvent mixture used.
- the protective solvent is a solvent selected from the group consisting of 1, 2-propanediol, 1, 3-propanediol, diacetin, triacetin, triethyl citrate and solubilizing foods such as vegetable oils.
- the extraction solvent or extraction / solvent mixture used for the extraction of the comminuted vanilla pods and the protective solvent used in step (c) of the process according to the invention have distinctly different boiling points, no azeotrope is formed on evaporation or distilling off, and the extraction Solvent or the extraction-solvent mixture can be removed cleanly and completely from the crude extract.
- the use of 1, 2-propanediol, the evaporation or distilling off the extraction solvent or the extraction solvent mixture of the crude extract with a residual amount of less than 1,000 mg / kg at a vacuum below 10 mbar particularly allows significant loss of flavoring aroma components of the crude extract.
- 2-Propanediol also known as propylene glycol
- 2-Propandiol belongs to the polyhydric alkanols and is chiral at C2, so there is an (R) - enantiomer and an (S) -enantiomer.
- 2-Propandiol is approved in the EU as a food additive.
- 1, 2-propanediol is used as a carrier.
- 1, 2-propanediol can be used as a racemate, as R or S enantiomer or as any mixture of its enantiomers.
- the ratio of the amount of vanilla bean seed used to the amount of protective solvent is crucial.
- a very concentrated vanilla extract is obtained.
- a saturation of the protective solvent phase occurs more quickly with valency-adding flavors, with the result that constituent components are already lost during the evaporation of the extraction solvent or of the extraction-solvent mixture.
- an excessive amount of protective solvent is not desirable because the extract is then very diluted and smells only slightly.
