Background

Flavors and fragrances play an important role in the production of numerous products such as cosmetics, pharmaceuticals, food and beverages. They are used as scents for perfumes as well as for the flavoring of foods and beverages. Flavors and fragrances are often produced by extraction from natural sources or chemical synthesis. Besides that, they can also be produced biotechnologically. Irrespective of how flavors and fragrances are produced, a purification of the suspension obtained is necessary before further use.

The challenge

The production of flavors and fragrances requires carefully selected raw materials. Besides the fluctuations in raw material quality, different techniques can be used for its production. Therefore, the property of the product to be filtered varies greatly. In order to avoid product losses, application-optimized purification processes are needed. Due to the different solvents used to produce flavors and fragrances, appropriate production equipment must be available for both the development of new processes and for large-scale production.

The solution

Depth filtration is an established and efficient technology for the purification of flavors and fragrances. FILTROX offers a wide range of products that cover all needs and applications to ensure gentle handling and maximum yield. Depth filtration technology is easily scalable due to its linearity. The filter material remains identical from lab scale to production scale and solutions are available for any size of operation.

PURAFIX® line – Filter sheets specifically designed for high purity applications
PURAFIX® depth filter sheets are made from specially selected raw materials to ensure lowest levels of ions and pyrogens. This product line is also available with a positive zeta potential. The combination of mechanical retention and electrokinetic effects results in the highly efficient removal of small particles and negatively charged molecules. Various filter sheet grades are available, from coarse to sterile filtration, to meet the requirements of all kinds of applications for the purification of flavors and fragrances.

ACTIVASORB® line – Decolorization and deodorization
ACTIVASORB® products are depth filter sheets made of purified cellulose and activated carbon. They are used for applications in flavors and fragrances production such as decolorization or deodorization. Using immobilized activated carbon is much more efficient than using loose carbon powder because it forces the impurities to contact the activated carbon. Therefore, this method requires a shorter contact time and uses less carbon. Furthermore, ACTIVASORB® products allow easy and clean handling. This filter sheet line covers grades for the pharmaceutical and food & beverage industry.
