据欧盟食品安全局（EFSA）消息，4月23日欧盟食品安全局就再次评估花青素（anthocyanins ）作为食品添加剂发布了意见。
欧盟专家组认为，现行的毒理学数据不能得出花青素的ADI数值，花青素作为食品添加剂的暴露数值要高于作为膳食食品的暴露数值（不包括着色食品），未来还需更多的毒理学数据以及化学特性数据来评估花青素作为食品添加剂。
部分原文报道如下：
Following a request from the European Commission to the European Food Safety Authority （EFSA）， the Scientific Panel on Food Additives and Nutrient Sources added to Food （ANS） was asked to provide a scientific opinion re-evaluating the safety of anthocyanins （E 163）。 The Panel concluded that the currently available toxicological database was inadequate to establish a numerical ADI for anthocyanins. For anthocyanins extracted from edible fruits and vegetables by aqueous processes, changes in composition would not be expected. The Panel concluded that provided exposure from use as a food additive was comparable to that from the diet the underlying conclusion in the 1975 SCF opinion that such food additives derived from natural sources would still apply.
The Panel concluded that refined exposure estimates of anthocyanins used as a food additive were much higher than dietary intakes and that these did not include intakes from colouring foods. Therefore the Panel would recommend that appropriate characterisation and toxicological data should be required to permit a further re-evaluation of anthocyanins including comparative data on anthocyanins （E 163） produced by aqueous extraction.
