26 Nov 2015 --- EXBERRY Colouring Foods produced by GNT are fully compliant with the new “EU Guidance Notes on the classification of food extracts with colouring properties”, which come into final effect on 29th November 2015. SGS, the world’s leading inspection, verification and certification Company, has undertaken an independent assessment of GNT’s products. Their comprehensive tests verify that GNT’s EXBERRY products are Colouring Foods, fulfilling all aspects of the EU Guidance Notes. This clearly differentiates them from additive colours.
