The Search for New Aroma Chemicals

Summary
Although up to 10,000 natural and synthetic aroma chemicals exist, the search for new or improved products in the industry is still going on. The investigation for new substances starts with the analysis of the possible benefits, the existing knowledge and the routes that can be followed.

The search for new flavour and fragrance substances can e.g. be initiated by the following guidelines:

isolation of new natural products (mixtures or character-impact compounds);
searching for open spots in groups of existing natural compounds;
studying the biogeneration (biochemical formation) of new volatile compounds;
investigation of reaction occurring during food processing (e.g. cooking, baking, frying);
predicting new groups of substances from structure-odour relationships.

Some recently published programs for the isolation of new products from nature will be discussed. A series of ideas for the development of new or improved flavour and fragrance substances will be revealed. These ideas concern new mono- and sesquiterpenoids, substitution of sterical or electronical parts (functional groups) of molecules by more stable ones. New materials with more organoleptic or olfactive value for money will be suggested.
