Patent Application
20120237660
This disclosure relates to 2-methoxy-5-(phenoxymethyl)phenol (hereinafter “compound A”) and its use in consumable products to create or modify the flavour thereof.
It is widely recognised that the flavour of consumable products consists of two parts, namely aroma and taste. In general the part that is perceived olfactively in the nasal cavity is described by the term “aroma”, whereas the part termed “taste” is used to describe the sensorial impact perceived in the mouth, and more particularly on the tongue. Sweetness is one of the five generally recognized taste sensations. By modifying taste or aroma of a consumable product, one is modifying its flavour. In particular, by modifying the sweetness of a consumable product, e.g. by enhancing its sweetness, one is modifying its flavour.
In the flavour industry there is a constant demand for compounds that create or modify the flavour of consumable products. Such compounds extend a flavourist's palette and result in greater product diversity for consumers. In particular there is demand for compounds that enhance the sweet-taste of consumable products because such compounds may replace or reduce reliance on conventional sugars the use of which can be undesirable, due to health and wellness concerns such as diabetes and obesity.
It has now been found that compound A may be used in consumable products to create or modify the flavour thereof. In particular it has now been found that compound A is a sweet-taste enhancer and is therefore capable of enhancing the sweetness of a consumable product.
The term “sweet-taste enhancer”, as used herein, refers to a compound that, when used in a consumable product comprising at least one other sweet-tasting compound, results in a more than additive increase in the overall sweet taste of the consumable product. In order for a compound to act as a sweet taste enhancer it requires the presence in the composition of at least one sweet-tasting compound.
Provided is method of creating or modifying the flavour of a consumable product by adding thereto compound A.
Also provided is a method of enhancing the sweetness of a consumable product by the addition thereto of compound A, the consumable product containing at least one sweet-tasting compound.
Also provided are consumable products comprising compound A, and in particular such consumable products that contain at least one sweet-tasting compound.
Also provided is the use of compound A in a method hereinabove described.
The term “consumable product” as used herein refers to products that may be placed in the oral cavity and ingested, or that may be placed in the oral cavity before being discarded, for example, mouthwash and chewing gum.
The present methods and products can be understood more readily by reference to the following detailed description of the various embodiments, and to the examples included herein.
Compound A is a known compound that has been described in Japanese patent 51-091,218. However, applicants have found that compound A may be used to create or modify the flavour of consumable compositions. In particular it has been found that compound A acts as a sweet-taste enhancer when added to a consumable product containing at least one sweet-tasting compound.
The discovery of ingredients that can create new flavour accords or modify existing flavour accords is, of course, beneficial. It is particularly beneficial however, if an ingredient possesses the property of sweetness enhancement as this would enable a reduction in the amount of sugar traditionally employed in certain consumable products, particularly foodstuffs and beverages. It has been found that when compound A is employed as a sweet-taste enhancer in consumable products comprising at least one sweet-tasting compound, the total amount of the sweet-tasting compound present in the consumable product may be reduced by 5% to 20%, in some embodiments by 5% to 10%.
Typically sweet-tasting compounds will be present in a consumable product in a concentration from 0.01% to 99%.
Examples of sweet-tasting compounds include, but are not limited to, fructose, glucose, sucrose, lactose, maltose, saccharin, aspartame, sucralose, neotame, sorbitol, xylitol, Aspartame, AceK, sucralose, maltodextrol, polyols, neohesperidin dihydrochalcone, naringin dihydrochalcone, rebaudioside A, stevioside, mannitol, erithrytol, xylose, rhamnose, Luo Han Guo extract, mogriside V (or lo han kuo extracts), stevia extract, thaumatin, inositol, cyclamate, monatin, and trilobatin.
Compound A may be added to a consumable product in order to create a flavour accord in and of itself. However, more typically, it would be added to a consumable product already containing one or more flavour ingredients and it would be used to modify an existing flavour accord. The compound A can be used to modify all manner of flavour accords. However, it is particularly useful in the modification of accords that include chocolate, coffee, cola, cherry, caramel, and/or fruity flavours including strawberry and/or apricot flavours.
Accordingly, in a particular embodiment, there is provided a method of modifying the flavour of a consumable product comprising the addition of compound A to a consumable product comprising at least one flavour ingredient.
Compound A may be added to consumable products within widely varying amounts depending on the nature of the consumable product, on the effect desired, on the nature and quantity of any other components of the consumable product and on the purpose of adding the compound A to a consumable product.
Flavour modifying amounts of compound A may be about 100 ppm to about 0.01 ppm, in particular embodiments about 50 ppm to about 0.01 ppm, in some particular embodiments about 10 ppm to about 1 ppm of the total consumable product.
Sweet-enhancing amounts of compound A may be about 1 ppm to about 20 ppm, more particularly about 1 ppm to about 10 ppm of the total consumable product.
These proportions are meant to be in no way limiting, and it is possible and permissible for the skilled person to work outside these limits, in order to achieve particular effects.
Compound A can be added to all manner of consumable products.

Compound A may be added alone to a consumable product to create or modify flavour.
Alternatively, it may be employed as part of a flavour composition containing other flavour ingredients, off note blocking or masking ingredients that block or mask the off tastes of known sweeteners, and commonly employed excipients, such as solvents and the like. In this manner, compound A may be added to a consumable product as part of a flavour composition. A typical flavour composition will comprise compound A, and one or more ingredients selected from sweet-tasting compounds, sweet-taste enhancers, off note blocking or masking ingredients, flavour ingredients and excipients. The flavour ingredients may be ingredients whose flavour is modified by compound A, or they may be merely part of an overall flavour package.
In another aspect there is provided a flavour composition for the creation or modification of flavour in a consumable product comprising compound A. In particular embodiments, the flavour composition is useful in the enhancement of the sweetness of a consumable product containing a sweet-tasting compound.
If compound A is employed in a flavour composition for use in a consumable product, it may be employed in said flavour composition in a concentration ranging up to about 99.99%, in particular embodiments from about 0.001% up to about 99.99% by weight of the flavour composition.
Compound A may be added to a flavour composition or a consumable product in neat form, or it may be dissolved in a solvent. It may be vehicularised, for example it may be entrapped with an entrapment material, for example polymers, capsules, microcapsules, nanocapsules, liposomes, precursors, film formers, absorbents, such as for example by using carbon or zeolites, cyclic oligosaccharides and mixtures thereof, or it may be chemically bound to substrates which are adapted to release flavour ingredients upon application of an exogenous stimulus such as light, enzymes, or the like.
Off note blocking or masking ingredients that may be used with compound A, in flavour compositions and consumable products, may be any known off note blocking or masking ingredients known in the art, non limiting examples of which include, chlorogenic acid and 4-(2,2,3-trimethylcyclopentyl)butanoic acid.

There now follows a series of non-limiting examples that serve to illustrate the present methods and products.
A 1% solution of compound A was prepared in ethanol.
This 1% solution was then further diluted, using water, to create a 10 ppm solution.
A panel of trained experts was then asked to evaluate the taste of this sample solution and to comment on any flavor attributes.
The sample was found to have the following flavour attributes:
Sweet upfront, spicy, phenolic, eugenol.
A 1% solution of compound A was prepared in ethanol.
This 1% solution was then further diluted, using water, to create a 5 ppm sample solution of compound A.
To determine the isointensity of this solution a panel of trained experts was then asked to evaluate the taste (in particular the sweet taste) of this sample solution in comparison to 0.5%, 1% and 1.5% sample sucrose solutions.
Panel testing was carried out in the following way:
Twenty millilitres of each of the samples was presented blind and in counter balanced order following a William's Latin square design, to 20 sweet sensitive panelists.
In two replications (over 1 session), panelists were asked to taste and rank the solutions from least sweet to most sweet.
The R-index statistics were then calculated between the 5 ppm 2-methoxy-5-(phenoxymethyl)phenol sample solution, and each of the sample sucrose solutions (0.5%, 1%, and 1.5%) to determine if they were significantly different from each other.
Samples were deemed significantly different if p<0.05 between the calculated R-index values and the critical value range of 35% to 65%.
An R-index significantly greater than the critical value range means that the compound A sample solution is significantly less sweet than the sucrose sample. An R-index significantly below the lower critical value range indicates that the compound A sample solution is significantly sweeter than the sucrose sample.
Results are detailed in Table 1.
Based on these results it was determined that the 5 ppm compound A sample solution was perceived to be iso-sweet to the 0.5% sucrose sample solution, and was perceived to be significantly less sweet than the 1.0% and 1.5% sucrose sample solutions (the calculated R-index values exceeding the critical values at p<0.05).
A 1% ethanol solution of compound A was added into a 7% sucrose water solution. This resulted in a 7% sucrose water sample solution containing 5 ppm of compound A.
To determine its isointensity a panel of trained experts was then asked to evaluate the taste (in particular the sweet taste) of this sample solution in comparison to sample water solutions containing 7%, 8%, 9% and 10% sucrose but not compound A.
Panel testing was carried out in the following way:
Twenty millilitres of each of the sample solutions was presented blind and in random order to 20 sweet sensitive panelists.
In two replications (over 1 session), panelists were asked to rank the solutions from least sweet to most sweet.
The data was then subjected to an R-index analysis as described in example 4.
Results are detailed in Table II.
Based on these results it was determined that the 7% sucrose+5 ppm of compound A solution was perceived to be significantly more sweet than 8% sucrose, significantly less sweet than 10% sucrose, and isosweet to 9% sucrose.
Consequently it may be concluded that compound A is behaving as a sweet flavour enhancer.
A 1% ethanol solution of compound A was added into a cola flavoured solution. This resulted in a cola solution containing 5 ppm of compound A.
A panel of trained experts was then asked to evaluate the flavour of this sample cola solution against a cola solution not containing compound A, and to comment on any perceived flavour attribute differences.
The experiment was then repeated for cherry and caramel flavoured solutions.
Results are detailed in Table III.
Although the embodiments have been described in detail through the above description and the preceding examples, these examples are for the purpose of illustration only and it is understood that variations and modifications can be made by one skilled in the art without departing from the spirit and the scope of the disclosure. It should be understood that the embodiments described above are not only in the alternative, but can be combined.
