Overview for Ethyl Vanillin:
Vanillin (4-hydroxy-3-methoxybenzaldehyde) is the primary chemical component of the extract of vanilla bean.
Natural vanilla extract is a mixture of several hundred compounds in addition to vanillin.
Artificial vanilla flavoring solution of pure vanillin, is usually of synthetic origin.
Synthetic vanillin and ethyl vanillin are used as flavoring agents in foods, beverages, and pharmaceuticals.
Ethyl vanillin (3-ethoxy-4-hydroxybenzaldehyde) is more expensive and has a stronger flavor.
Compared to vanillin, ethyl vanillin has an ethoxy group (-O-CH2CH3) rather than a methoxy group (-O-CH3).
The largest single use of ethyl vanillin is for flavoring.
Bourbonal is first synthesized from eugenol found in oil of clove and afterward synthesized from lignincontaining sulfite liquor, a by-product of wood pulp processing in paper manufacture.
While some ethyl vanillin is still made from lignin waste, today most synthetic vanillin is synthesized in a two-step process from the petrochemical precursors: vanillin, ethyl vanillin, and guaiacol and, glyoxylic acid.
Vanilla, being the world’s most popular flavoring materials, finds extensive applications in food, beverages, perfumery and pharmaceutical industry.
With the high demand and limited supply of vanilla pods and the continuing increase in their cost, numerous efforts of blending and adulteration in natural vanilla extracts have been reported.

Ethyl vanillin and vanillin, the major phenolic constituents in vanilla products, are widely used as flavoring agents in foods and beverages.
Ethyl vanillin, also used as a synthetic compound, is 2.5 times stronger in flavor than vanillin and used to substitute a large amount of vanillin, since it is less expensive and keeps better in storage and transport.
Ethyl vanillin is converted to 3-ethoxy4-hydroxybenzaldehyde and 3-ethoxy-4-hydroxymandelic acid after dietary intake.

Ethyl Vanillin is a fine powder with three times more potency than Vanillin and offers a more concentrated flavor profile in order to provide sweet, pure and rich creamy notes of vanilla.

General description
Ethyl vanillin is one of the main components of artificial vanilla flavorings.
Bourbonal is also used a flavor enhancer.

Ethyl vanillin is a phenolic compound substituted to form ethyl vanillin.
As the name suggests, it is a fine white or yellowish crystalline powder.
Bourbonal can be considered a synthetic vanilla flavor.
Bourbonal has slightly more potent vanilla flavor than vanillin alone.

Ethyl vanillin (bourbonal, vanillose).
Ethylvaniline (C6N3ON • OS2N5-CHO) is vanillin, in which the methyl group of vanillin is replaced by ethyl.
Although ethyl-vanillin has been known for many years, the complexity of its preparation without unpleasant impurities hampered its sales, but a quite acceptable product is currently being manufactured and widely used.
The use of ethyl valaniline is economically viable, since it is claimed that it is five times stronger, but only four times more expensive than vanillin. Ethylaniline smells a little different from vanillin, but in most of the tasting tests described above this difference is not found.

The choice of good vanilla beans requires experience.
Once it was considered important to have vanillin crystals on the surface, but we once encountered a falsification - sprinkling pods with crystals of benzoic acid.
The only correct method to evaluate the quality is to prepare an alcohol extract and flavor them with a fondant.

Vanilla extract is prepared by slicing the grain into small pieces and soaking them successively in batches of hot 65-70% strength alcohol.
So you can ensure obtaining natural vanilla flavor.
Currently there are many commercially available extracts, representing a mixture of natural and synthetic products.

Ethylvanillin vs. vanillin
Since vanilla and vanillin are both quite scarce, people have been looking for cheaper alternatives for decades.
Hence, you might have heard of ethylvanillin as well.
This isn’t the ‘regular’ vanillin which is present in vanilla.
It is a slightly different molecule.

Ethyl vanillin is often used to substitute a larger amount of Vanillin in a fragrance when a discoloration problem arises, due to the active hydroxyl- or aldehyde-groups of the Vanillin/Ethylvanillin molecules.

As a flavouring agent, ethyl vanillin due to its fragrance potential is used in the production of chocolate.
It is used in the food and beverage industry as a flavouring agent, specifically for the flavouring of foods, chocolates, ice creams, and beverages.

Ethylvanillin is an artificial molecule, it does not appear in nature naturally, whereas vanillin does. It also happens that ethylvanillin is a lot stronger in flavour than vanillin. Therefore, when using ethylvanillin even less of the molecule is required to get the same intensity of vanillin flavour.

Ethyl vanillin is an important food additive and flavouring agent approved by FAO/WHO, has a vanilla odor four times that of vanillin and shows anti-mutagenic activity.
Ethyl vanillin is used as flavoring agent and/or as an additive by the food, cosmetic, or pharmaceutic industries.
Ethyl vanillin possesses antioxidant and anti-inflammatory properties.
The antioxidant activity of ethyl vanillin was much stronger than that of vanillin in the oxidative hemolysis inhibition assay, but was the same as that of vanillin in the ORAC assay.
Oral administration of ethyl vanillin to mice increased the concentration of ethyl vanillic acid, and effectively raised antioxidant activity in the plasma as compared to the effect of vanillin.
The antioxidant activity of ethyl vanillin might be more beneficial than has been thought in daily health practice.
The anti-angiogenic, anti-inflammatory and anti-nociceptive properties of EVA are based on its suppressive effect on the production of nitric oxide possibly via decreasing the reactive oxygen species level.

Ethyl vanillin, also known as bourbonal or ethyl protal, belongs to the class of organic compounds known as hydroxybenzaldehydes.
These are organic aromatic compoundscontaining a benzene ring carrying an aldehyde group and a hydroxyl group.

Ethyl vanillin is used as an alternative to vanillin, i.e. as a flavoring agent in foods, beverages, confectionery, and pharmaceuticals.
Ethyl Vanillin is also used in perfumery.
Ethyl vanillin possesses a flavor and odor approximately three times as intense as vanillin; hence the quantity of material necessary to produce an equivalent vanilla flavor may be reduced, causing less discoloration to a formulation and potential savings in material costs.
However, exceeding certain concentration limits may impart an unpleasant, slightly bitter taste to a product due to the intensity of the ethyl vanillin flavor.

Ethyl Vanillin APPLICATIONs:
This flavour give the sweet Ethyl Vanillin taste which is more intense than Vanillin.
The strength and sweetness is about 3 to 4 times stronger than Vanillin.
This flavour gives more than sweetness strength when compare to Vanillin.
Ethyl Vanillin incorporates delta and gamma lactones which impart creaminess with Dextrose Monohydrate as carrier.
Ethyl Vanillin is particularly good in all bakery products such as biscuits, cookies, cakes, chocolate products, toffees, ice-cream and cereal products.
The recommended dosage is 0.1% for all bakery, chocolate and confectionary products.
The recommended dosage for beverage products such as milk shakes, chocolate drinks, cereal drinks is 0.05% of base weight.

Use & Benefits: 
Flavors are very helpful in cosmetics, just like in other categories like bakery, dairy or confectionary.
In cosmetics, they can be used to mask the disagreeable odor from any of the ingredients or to provide a uniform scent to the product.
The fragrance is a factor because of which people may want to use the same product over and over, to get the same effect at the same time and look and feel fresh.
Vanilla also has a soothing property for the skin.
So, when Ethyl Vanillin is applied to mildly irritated skin, Ethyl Vanillin can show a soothing or calming action.

Preparation of Ethyl Vanillin:
Ethylvanillin is prepared from catechol, beginning with ethylation to give guaethol.
This ether condenses with glyoxylic acid to give the corresponding mandelic acid derivative, which by oxidation and decarboxylation, gives ethylvanillin.

Natural vanilla.
Vanilla is obtained from the pods of a species of tropical orchid, known as Vanillaplanifolia.
It is a climbing plant that needs the support of trees or poles, and under such conditions it grows to 4,5 m.
Its homeland is Central America, but it is mainly grown in Madagascar, Seychelles, Reunion and Tahiti.
In these areas, artificial pollination of flowers is necessary, since there are no special kinds of bees pollinating vanilla in places of uncultivated growth.
The flowers have narrow cups surrounded by thin petals that slowly develop over a period of several months into long narrow pods measuring about 15-23 cm.
To develop a characteristic vanilla flavor, a drying process is needed, similar to that used for cocoa (different versions of this process are used).
The pods are collected in green and soaked in walnut oil for about a month, after which they fully ripen and turn black.

In the process of drying, glycosides, which are the precursors of aromatic substances, decompose into vanillin and glucose, and although vanillin is the main product, other aromatic substances are formed in small amounts. They contribute to the natural aroma of vanilla, which is absent in the synthetic product.

ChEBI: A member of the class of benzaldehydes that is vanillin in which the methoxy group is replaced by an ethoxy group.

Production Methods for Ethyl Vanillin:
Unlike vanillin, ethyl vanillin does not occur naturally.
Ethyl Vanillin may be prepared synthetically by the same methods as vanillin, using guethol instead of guaiacol as a starting material.

Preparation of Ethyl Vanillin:
From safrole by isomerization to isosafrole and subsequent oxidation to piperonal; the methylene linkage is then broken by heating piperonal in an alcoholic solution of KOH; finally the resulting protocatechualdehyde is reacted with ethyl alcohol.
From guaethol by condensation with chloral to yield 3-ethoxy-4-hydroxyphenyl trichloromethyl carbinol; this is then boiled with an alcoholic solution of KOH or NaOH, acidified, and extracted with chloroform to yield ethyl vanillin.

Reactivity Profile of Ethyl Vanillin
Protect from light.
Aldehydes are readily oxidized to give carboxylic acids.
Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents.
Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids.
These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction).
The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation.

Ethyl vanillin is generally regarded as an essentially nontoxic and nonirritant material.
However, cross-sensitization with other structurally similar molecules may occur.
The WHO has allocated an acceptable daily intake for ethyl vanillin of up to 3 mg/kg body-weight.
LD50 (guinea pig, IP): 1.14 g/kg
LD50 (mouse, IP): 0.75 g/kg
LD50 (rabbit, oral): 3 g/kg
LD50 (rabbit, SC): 2.5 g/kg
LD50 (rat, oral): 1.59 g/kg

Frequently Asked Questions about Ethyl Vanillin:

What does Ethyl Vanillin do as an Adulterant?
Ethylvanillin has been used for decades in the food industry, because it is roughly three times as potently flavorful and fragrant as vanillin. Its scent is slightly different from the latter, and just to demonstrate how much it is used, its scent is best described as “vanilla cake icing,” somewhat sweeter than vanilla from its caramel notes. This is because a tremendous number of food products contain this ingredient.

Ethylvanillin does not exist in nature. When it is encountered in a vanilla extract, it does not arise from the fruit of Vanilla planifolia, but has been added later. As such, the extract cannot be considered pure and natural anymore, and its organoleptic properties will be affected.

Is Ethyl Vanillin Dangerous?
Absolutely not. Ethylvanillin is regarded as a very safe molecule to be used in flavors and aromatic compositions, and has been for decades [2]. The only danger there is to alter an otherwise genuine vanilla extract, which is more precious.

The craving for “all-natural” flavors and fragrances in the last years have in fact had dramatic consequences on the vanilla market. Shortages and unpredictable climatic conditions caused the prices of the vanilla extracts to go all over the place [3]. Using artificial vanillin and ethylvanillin of course does not exactly reproduce the aroma of the natural extract, but can in some instances reduce the pressure on the market.

How do we Detect Ethyl Vanillin?
Ethylvanillin is distinct from vanillin on both gas and liquid chromatographic methods, so it can be detected as a single peak with the proper method. When using mass spectrometry, it also features a very unique mass spectrum, which makes it even easier to spot it. The main challenge is to detect relatively low amounts of the compound. Indeed, since it is more potently aromatic than vanillin, only small quantities are sufficient to obtain the desired aroma.

Ethylvanillin is an efficient and accessible artificial flavoring agent, that can conveniently be used in foods with no risk. When an all-natural vanilla is required, it can be fairly well detected by various chromatographic techniques. Think of ethylvanillin the next time you eye that yummy vanilla cake at the grocery store!
