Vanilla flavor

Vanilla beans come from plant genus Vanilla (family: Orchidaceae), a tropical climbing orchid, and originally came from Mesoamerica, though variations on the vanilla orchid have now scattered around the world. The flower that produces the vanilla bean only blooms for one-day.

Vanilla planifolia and Vanilla tahitensus are two species from this genus have been approved in most countries, however because of its pod quality and yield, Vanillus planifolia is widely recommended. V. Planifolia is the most valued for its flavor tendencies and is, consequently, substantially cultivated and used for the manufacturing of meals additives

Vanilla pods are macerated and percolated in a solution of ethanol and water and thus vanilla extract is obtained. According to FDA specifications, pure vanilla extract contains 13.35 ounces of vanilla beans per gallon during extraction.

The active constituents of vanilla are responsible for its various biological and therapeutic activities. The flavor profile of vanilla contains more than 200 components, of which only 26 occur in concentrations greater than 1 mg/kg.

Vanilla extract contains manganese and potassium which both play an important role in brain function. Natural vanilla extract contains numerous antioxidants, including vanillic acid and vanillin.

The aroma and flavor of vanilla extract is attributed mainly due to presence of vanillin (4-hydroxy-3-methoxybenzaldehyde), which occurs in a concentration of 1.0 - 2.0% w/w in cured vanilla pods.

Vanilla flavor is an indispensable ingredient in many bakeries and confectionary products, custards, ice creams, and puddings. Vanilla is likewise used as a fragrance component.

Blending flavoring extract with synthetic materials

Flavors are often very complex mixtures of ingredients, whether naturally occurring or created form synthetics and food technologists have gone to great lengths to assure that the blend of synthetic flavors will meet with consumer acceptance.

The flavoring extract may be reinforced with a synthetically produced flavor principle; however, in this case the resulting product must be labeled as containing artificial or imitation flavor.

This labeling requirement holds even though the synthetic ingredient is naturally present in the extract. Any incidental additives which are present in the food at insignificant levels and which do not have any technical or functional effect in that food are exempt from food labeling.

In the United States ‘boosted natural’ flavors are allowed. This means that flavors may contain up to 0.1% artificial (synthetic) flavor components and still be classified as ‘natural’.

Artificial flavors such as artificial cherry, raspberry, strawberry, watermelon and vanilla( can cover up the absence of more expensive ingredients in manufactured foods like mixes and soft drinks.

What is the definition of flavor?

Flavor is a biological perception, a sensation produced by a material taken in the mouth, perceived principally by the sense of taste and smell, also the general pain and tactile receptors in the mouth as received and interpreted by the brain.

It is said that there are basically five flavors namely sweet, sour, bitter, salt and savory.

A flavor can in other terms be called the essence of food. Earlier it was considered that there are just four flavors. It was just in the recent years the fifth flavor that of natural amino acid glutamic acid and certain nucleotides was observed.

The Council of Europe defined flavor: A flavoring substance is a chemically-defined compound which has flavoring properties. It is obtained either by isolation from a natural source or by synthesis.

Favoring properties are those which are predominantly odor producing and which may also affect the taste.

Flavor is never eaten in its natural state, it is always incorporated in a matrix or delivery system.

Although food acceptance in humans is determined mainly by appearance and texture, flavor is nevertheless also important. For example, spices are added to food not for their nutritional value, but for their taste and favor.

Nature of flavor components

The study of the chemistry of odor and flavor has been going on for a long time. Plant materials used in foods depend for their characteristics aroma and flavor on a complex blend of organic chemicals produced in the plant tissues during its normal growth.

Hundred of chemicals present in natural foods and flavorings have already positively identified but some still defy categorization.

Nature is complex and does not readily reveal many of her secrets. The techniques necessary to separate aromatics compounds from inert plant tissues are often involved with tedious work.

Many of the chemicals which have most significance on the odor and flavor profile are known to be present only in trace quantity and often demonstrate very limited stability when isolated purified. Food whose flavor cannot be attributed to one or a few outstanding flavor notes; their flavor is the result of the complex interaction of a variety of taste and odor components.

Flavor components can include a single, ‘primary’ component, or be distributed in various ways among multiple components. In general, the majority of flavor systems include primary flavor components, and these fall into broad categories:
1. Simple extractions
2. Extracts
3. Emulsions

All these factors make research into the chemistry of flavor components one of extreme complexity but, in spite difficulties, considerable progress has been made.

Natural food flavor classification

Natural flavor is obtained by physical separation, enzymatic process or microbial process for vegetable or animal sources, either in the raw state of after processing including drying, torrefaction and fermentation.

Natural food flavor generally may classify into three distinct groups:
*Low flavor impact – It would be a longer term, lesser-defined character of less recognizable nuance or character.

*Medium flavor impact

*High flavor impact – it would be immediately of recognition of particular nuance or character.

Impact is the time-oriented degree of perception. The flavor impact of a product is a measure of the speed of perception of volatile aroma.

Those in the group in the first, form the basis of a staple diet providing a full range of protein, fats, carbohydrate and vitamins necessary to maintain the body in good health.

Those in the second group occupy half way place in that they are usually eaten in the natural state either as part of a meal to produce entirely different flavor sensation the mouth, or at other times as a snack.

Food flavors may be classified in many ways; but from the point of view of their chemistry.

The most realistic classification is that based on their mode of formation either naturally by biogenetic pathways from known precursors or by processing in which biological ,chemical or physical conditions are imposed on natural or artificial start materials.

The Importance and Classification of Food Flavor

Flavors represent a class of food additives that has had comparatively little legislation. This is probably due to the relatively large number of ingredients used in flavoring, the very small quantities involved and the difficulties of regulating added substances by analytical methods.

The flavor of food is all important. Much of our diet by itself is unattractive, unappetizing and often so lacking in intrinsic flavor.

If the aroma and flavor is enticing and satisfying to the eater then it is digested better and results in an overall feeling of satisfaction.

Sensory information obtained from the interaction of fragrance and flavor molecules with olfactory and taste receptor are processed in defined cerebral areas, resulting in perception.

It does not matter how the is look and how balanced nutritionally it is, if it does not smell and taste goods then these essential reflexes are not activated and eating remains mere chore rather than the positive pleasure which it should be.

Although food acceptance in humans is determined mainly by appearance and texture, flavor is nevertheless also important. Spices are added to food not for theory nutritional value, but for their taste and flavor.

The flavor of any food product, confectionary or beverage will depend upon all ingredients used in its preparation and the nature of processing involved.

Flavors may classified in many ways, but from the point of view of their chemistry, the most realistic classification is that based on their mode of formation, either naturally by biosynthetic pathways from known precursors, or by processing in which biological, chemical or physical condition are imposed on natural or artificial starting me trials.

They also can be classified as:
-Prime ingredients
-Flavorings
-Colorings
-Additives or stabilizer

Favors can be classified by the general sensations that one fells when eating different foods. It is generally agreed that taste sensations are divided into four major categories: saltiness, sweetness, sourness and bitterness.

However food flavors are usually classified by the food sources in which they are normally detected because more than one flavor sensation is usually triggered by a food flavors.
