Most of the people identify vanilla as a flavor used to enhance the taste of food products and dietary supplements. However, a majority of these people do not anything more about it. This article intends to introduce you to the inside and out of this flavoring agent.

A tropical orchid, Vanilla is probably the world’s most popular flavoring agents mainly used in food, pharmaceutical preparations and perfumery. Natural vanilla constitutes of flavors derived from two different species of vanilla orchids – Vanilla tahitensis and Vanilla planifolia. Vanilla extract owes its flavor and fragrance to over 200 components, with vanillin (4-hydroxy-3-methoxybenzaldehyde) being the key component constituting 1—2 percent w/w of cured vanilla pods. [1]

Like wine, natural vanilla displays different taste and potency, depending on the places where it grown including Madagascar, Mexico, or Tahiti. For example, Madagascar vanilla, referred to as Bourbon vanilla, is among the most sought after versions, courtesy its sweet aroma and rummy taste. [2] The vanilla extract draws its color from vanilla beans that have dark brown color.

Composition of vanilla extract

Vanilla extract is a solution of extractable components of vanilla beans prepared in aqueous ethyl alcohol. It can either be produced directly from vanilla beans or can be synthesized in a semisolid form called vanilla oleo-resin by adding concentrated vanilla extract to the alcohol. The major constituents of vanilla extract may contain one or more of optional ingredients including glycerin, propylene glycol, dextrose, sugar (including invert sugar) and/or corn sirup (including dried corn sirup). [3]

The vanilla extract, known for its pure and delicate spicy flavor, is extracted from fermented vanilla pods. The quality of the extract depends on the vanillin content. However, only less than 1 percent of vanillin was obtained from vanilla pods in 2010 because extraction of this fragrant volatile constituent is a laborious and costly affair. Extraction of vanilla is a very labor-intensive job. An estimated 500 kg of vanilla pods are required to produce 1 kg of vanillin, which corresponds to the pollination of nearly 40,000 vanilla orchid flowers. Beans are plucked while still green, which are purchased by fermentation plants that sort, blanch, steam, and dry them in the sun. Thereafter, they are sorted again and left to dry in the shade. Workers, then, ferment them while continually analyzing their aroma and inspecting each bean for quality.

Considering the costs and complexities involved in extracting vanillin from vanilla orchid, the majority of vanillin demand is met through synthetic production using lignin and eugenol as starting material. [4]

Need of artificial vanilla

Processed vanilla beans from natural sources contain only 2 percent of extractable vanilla flavor, which translates into a hefty price tag of $11,000 per kg for pure vanilla.

Dairy products including ice cream and yogurt have been dependent on natural vanilla for many years. The U.S., Food & Drug Administration (FDA) warrants to flavor vanilla ice cream from natural vanilla. Carol McBride, U.S. vanilla category manager at Symrise suggested that the total amount of all the vanilla beans harvested across the world is not enough to meet the “flavoring” needs of the world. [5]

Pure vanilla extract vs. imitation

Considering the scarcity of pure vanilla extract, many manufacturers are involved in producing artificial or imitation vanilla, made using a synthetic vanilla flavor. This imitation product has a strong vanilla flavor, which can be produced cheaply in a local lab. While pure vanilla extract is produced from three major ingredients including vanilla beans, alcohol and water, imitation vanilla is made from synthetic vanillin, which could be procured from wood pulp waste including clove oil, pine bark and fermented bran.

Homemade vanilla extract

Hearing about the complexities involved in manufacturing vanilla extract from natural sources may make you wonder if it is such a difficult thing to get. But, the good news is it’s not. You can even prepare it at home. Here is a step-by-step guide to prepare this delicious and fragrant food product at home.

Step 2: Now pour these ingredients in a food-grade glass jar. For each cup of alcohol, you can use three to five beans.

Step 3: Pour alcohol over the vanilla beans, until all beans are submerged completely.

Step 4: Leave the contents for six weeks, or until you see a dark brown extract with a strong vanilla fragrance. [6]

Vanilla extract can also be prepared through hot method. The vanilla extract prepared through this method has slightly stronger flavor and takes comparatively lesser time. In the hot method, alcohol is poured in a pan and is heated until it just simmers. Then, add vanilla beans into the empty alcohol bottle and pour the hot alcohol over the top until the beans are completely submerged in alcohol. Wait for four weeks, or until the mixture starts looking and smelling like vanilla extract.

In addition to vanilla extract, other ethanol containing products such as mouthwash, food flavorings, perfumes and cold medicines can also cause intoxication. [8]

In comparison, beer has around two to six percent of alcohol content while wine contains about 10 to 20 percent alcohol. Distilled liquors have around 40—50 percent alcohol content. While in most cases, vanilla extract loses its alcohol in the cooking process, its direct ingestion may produce effects similar to drinking hard liquor. A report from the Internet Scientific Publications (ISPUB) suggests that a person weighing nearly 154 pounds who consumes a 12-ounce bottle of extract will have a peak blood alcohol level (BAC) three times higher the legal driving limit.

Vanilla doesn’t need an expiration date
