Are artificial colours likely to disappear completely?
Among artificial colours it is the Azo dyes that are of concern, their structure being very similar to aspirin. If people are allergic to aspirin they may show a similar response to these dyes. Carotenes, in particular beta carotene, appears to be a popular alternative for yellow/orange artificial dyes such as Tartrazine and Sunset Yellow. Based on hydrocarbon chains, they appear to cause less allergic reaction. Unfortunately I cannot agree with your comment that fewer artificial colours are being used. Have a look at products designed for children. Blue raspberry is very common, children’s ‘penny tray sweets’ often contain artificial colourings, along with jams, jellies, a variety of canned goods, confectionery and soft drinks. Until natural colours can be produced at the same cost as artificial, with the same variety, stability in processing, and consistency, I rather think they will remain. I am concerned about artificial sweeteners – each product claims to contain them within legal
