WK Kellogg is accelerating plans to eliminate artificial colours and the preservative BHT (butylated hydroxytoluene) from its entire portfolio of cereals and cereal packaging. As part of the reformulation programme, WK Kellogg will replace artificial colours with colours derived from natural sources, including fruit and vegetable juices and other plant-based ingredients. WK Kellogg has already reformulated foods served in schools to remove artificial colours and stopped launching new products containing artificial colours from January 2026. WK Kellogg recently introduced its SPOONS on-pack nutrition guide, which highlights attributes including simple ingredients, fibre and protein. WK Kellogg said the updated recipes are intended to deliver a “simplified” ingredient proposition without compromising on the taste or visual appeal of its cereal brands.
