用天然着色剂取代人造食用染料是当前的市场趋势，尽管美国和欧盟(EU)都没有就食品色素定义天然色素。消费者团体担心合成着色剂的安全性，此外，许多天然衍生着色剂对健康有好处。食品科学家经常面临用天然替代品取代人造着色剂的任务。这可能是具有挑战性的，因为自然衍生的着色剂通常不太稳定，而且实际上可能无法获得所有想要的色调。本文综述了可合法替代合成着色剂的着色剂的化学和物理性质、局限性及其更适合的应用。讨论了某些食品的问题和挑战，并对未来可能出现的着色剂进行了简要描述。
Replacement of artificial food dyes with natural colorants is a current marketing trend, notwithstanding the fact that neither the United States nor the European Union (EU) has defined natural with respect to food colors. Consumer groups have concerns over the safety of synthetic colorants, and in addition, many of the naturally derived colorants provide health benefits. Food scientists frequently have the assignment of replacing artificial colorants with natural alternatives. This can be challenging, as naturally derived colorants are usually less stable, and all desired hues might, in fact, not be obtainable. In this review, the chemical and physical properties, limitations, and more suitable applications for those colorants that are legally available as substitutes for the synthetic colorants are summarized. Issues and challenges for certain foods are discussed, and in addition, colorants that may be available in the future are briefly described.
