Distillation in flavor industry

Distillation is a process in which the separation of components in a mixture is achieved due to differences in volatility, that is differences in vapor pressure, of the components in the mixture to be separated.

In flavor industry distillation is frequently utilized for the isolation of flavor compounds, the formation of artifacts during distillation has been a subject of considerable interest.

It is extensively used throughout the flavor industry for:
*the recovery of volatile components from aromatic plants materials by distillation. The distillation process can take many form, Direct steam distillation in a blow over uses a very short condensation column. Condensed product is collected directly.

*Fractionalization of essential oils. The process of reclaimating the aroma of fruit products and specifically fruit juice concentrates by fractional distillation.

*The purification of volatile aromatic chemicals from more or less volatile impurities.

*The recovery of solvents during the process of extraction

*The concentration of natural flavoring materials

*In destructive distillation for the production of pyroligneous acid

*In numerous research and analytical technique

After the separation of extract and extraction material a complete removal of solids and cloudy components has to ensue. This filtration process can be performed with continue or discontinuous filters or by centrifugation with full jackets, reciprocal; pusher or sieve centrifuges.

Essential oil, fruit extracts and synthetic flavorings

Essential oil, fruit extracts and synthetic flavorings
Essential oils form a major source of flavorings. Essential oils are odorous components of plants and plant materials that are the characteristics odors of the materials from which they are extracted, because of the large production of juice, quantity of essential oil of orange are produced as by-products. For this reason, there is a little need for the production of synthetic orange flavoring.

Fruit extracts have been used as flavorings, but these are relatively weak when compared to essential oils and oleoresins. An oleoresin is a solvent extract of spices from which the solvent, usually a hydrocarbon, has been removed by distillation, Because of their weak effects, fruit extracts may be intensified by combining them with other flavorings. Synthetic flavorings usually less expensive and more plentiful than natural flavorings. On the other hand, natural flavorings are often more acceptable. In fact, one of the problems with natural flavorings is that they may vary according to season and other controllable variables.

Synthetic flavorings, however, can be reproduced quite accurately,. Many artificial flavors, such as amyl acetate (artificial bananas flavor), benzaldehyde (artificial cherry flavor) , and ethyl caproate (artificial pineapple flavor), are added to confectionaries, baked products, softdrinks, and ice-cream. These flavorings are added in concentrations of 0.03% or less.
