The role of a flavour is simply to impart sensory pleasure to a good, beverage, tobacco, or pharmaceutical, and in doing so it serves a diverse function. It is important to understand the function expected of the flavour so that the type best suited for this function can be delivered.
The flavor and fragrance are essential components in the food manufacturing sector. Because of the rising customer demand for natural and sustainable products, natural flavors are an ever-challenging field for study in both the academic world and the food business.

The three main categories of flavourings are: Essential oils and natural extracts are obtained from natural sources such as flowers, fruits, etc. The processes used included solvent extraction, steam distillation, etc. Aroma chemicals are single compounds, either produced biotechnology processes. Formulated flavours are complex blends of aromatic m...
IOFI is the International Organisation of the Flavour Industry, based in Geneva, Switzerland. The IOFI Code of practice [3] provides additional comments and interpretation of the EU regulation. In particular it includes guidelines on the IOFI Interpretation of the Term “Natural”.
Thanks to Mother Nature’s gifts on one hand, and human creativity on the other hand, a wide range of natural sources and processes can be used to produce food flavourings, which are usually complex mixtures of chemical compounds. Many organic compounds have a flavouring impact, which is not correlated to their concentration. What makes it even more...
Due to the volatile nature of flavour components, gas chromatography (GC) is the most common way of isolating them. The most widely used type of detector is Mass Spectrometry (MS), which enables each compound to be precisely identified. A first approach is to screen all or almost all compounds present, identify and quantify them, in order to compar...
Simultaneous Distillation Extraction (SDE) is the technique used in the German official method, and used in most expert laboratories, especially for testing fruit juices and fruit products. The main advantage is that this technique enables the extraction of a wide range of compounds, thus covering the main aroma compounds of fruit flavours: esters,...
In full scan mode, GC-MS chromatograms usually show around one hundred identifiable and quantifiable compounds. Most of them can be identified through the NIST MS database. An accurate quantification then requires determining individual response factors of each compound, taking into account both the extraction rate and the chromatographic response....
Using the enantioselectivity of chiral chromatography stationary phases, the R and S spatial conformations (i.e. enantiomers) of chiral molecules can be appropriately separated and quantified. Most industrial chemical synthesis processes use mineral catalysers, leading to racemic mixtures of R and S forms. Some fine chemistry methods might also pro...
Liquid chromatography is the most suitable technique for analysing thermally instable or non-volatile compounds. A typical example is the use of limonin, a key compound causing bitterness in citrus drinks. This can also be used especially for “salty” aroma in which the impact compounds are usually less volatile. Multi-dimensional chromatography usi...

Whereas in prehistoric times, only herbs and spices could be employed for flavouring purposes, today a broad spectrum of flavourings is available, not only for use in the individual household, but especially for the production of food on an industrial scale.
2.2 Flavourings are products that are added to food to impart, modify, or enhance the flavour of food (with the exception of flavour enhancers considered as food additives under the Codex Class Names and the International Numbering System for Food Additives - CAC/GL 36-1989).
