What are flavours/aromas?
Flavours, or aromas, are usually strong-smelling organic compounds with characteristic pleasant odours. These substances are often of plant origin, or they are synthetically produced. Since antiquity flavour products have been used for flavouring foods and beverages or to a lesser extent for their preservative properties.
How to use flavours/aromas?
Whatever their origin and application in food, beverages or perfumed products, flavours should be used in an applicable form. This is mostly achieved by spray drying. In general, prior to spray drying all natural or synthetic flavouring compounds have to be formulated with water soluble gums and carbohydrates. By forming a protective encapsulated surface film around each particle, the volatile flavour is retained.
The mixing of flavours/aromas
The mixing takes place at 30-50oC to a feed with a solid content of 40-50%, where after this feed is homogenized and spray dried.
