Natural food colorants are foods in their own right and edible at any point in the production process. They are made from edible fruits, vegetables and plants and without the use of chemical solvents or additives. As consumers continue to demand natural ingredients that they can easily recognize and feel safe consuming, natural colors are ideally suited to meet this growing consumer requirement.
However, food colorants are notoriously difficult to handle in wet feed, slurry or cake, exhibiting poor flow characteristics and a cohesive tendency. They are also temperature sensitive. When these difficulties are added to the specific requirements for colour and taste, it becomes clear that it is critical to select the right dryer.
