Scientific opinion on the amendment of the specifications for vegetable carbon (E 153) as a food additive. [PDF]
EFSA JAbstract The food additive vegetable carbon (E 153) was re‐evaluated by the EFSA ANS Panel in 2012. During that re‐evaluation, data gaps were identified, in particular with respect to impurities and particle characterisation. Following a European Commission call for data to address these gaps, one interested business operator (IBO) submitted analytical
