Abstract
The present invention relates to a process for producing an ethanol-free vanilla extract, and an ethanol-free vanilla extract obtainable by the process according to the invention. In particular, the present invention relates to an ethanol-free vanilla extract comprising at most 100 mg/kg ethanol, the use of this ethanol-free vanilla extract and products comprising the ethanol-free vanilla extract. The focus of the present invention is in particular to provide an ethanol-free vanilla extract which contains only traces of ethanol naturally contained in fermented vanilla beans and is produced without the use of ethanol.
Claims19
An ethanol-free vanilla extract obtainable by a process comprising:
- (a) preparing fermented vanilla beans;
- (b) crushing the fermented vanilla beans;
- (c) extracting the crushed vanilla beans with an organic extraction solvent or an extraction solvent mixture comprising at least one organic extraction solvent having a log P value of from −0.8 to 0.4 to obtain a raw extract, wherein the organic extraction solvent having a log P value of −0.8 to 0.4 is selected from the group consisting of methanol, acetone, propan-2-ol, propan-1-ol, methyl acetate, ethyl methyl ketone, and a combination of any of the foregoing;
- (d) adding a protective solvent to the raw extract, wherein the protective solvent is selected from the group consisting of 1,2-propanediol, 1,3-propanediol, diacetin (glyceryl diacetate), triacetin, and triethyl citrate;
- (e) filtering the raw extract;
- and
- (f) distilling off the extraction solvent or the extraction solvent mixture from the raw extract to obtain a vanilla extract.
