Flavours and Fragrances
Chemistry, Bioprocessing and Sustainability
edited by R. G. Berger

Flavours and Fragrances is an introduction to aroma chemicals, essential oils, fragrances and flavour compositions for the food, cosmetics and pharmaceutical industry.

The present state-of-the-art technology, the future use of resources and biotechnological approaches for the production of the respective chemical compounds are described.

A large section is devoted to the description of the renewable resources of flavours: spice plants, fruits from moderate to tropical climates, vegetables, fermented and heated plants.

Analytical methods, such as gas chromatography coupled to human or electronic noses or to a mass spectrometer, are outlined and consumer trends, legal and safety aspects are described.
