GNT vs Exberry

What’s the difference between Exberry and GNT and their relation.

From a Vision for truly Natural Coloring Solutions to a Global Market Leader.

Established 40 years ago, GNT started from humble beginnings in the German city of Aachen with one man’s vision to produce coloring concentrates in the most natural way possible. Our founder coined the term ‘Coloring Foods’: food concentrates used solely for the purpose of delivering color to food and beverages. Coloring Foods are now becoming the industry standard in many markets.
