The invention provides a method for producing a dairy powder or a dairy concentrate.The pH of a liquid dairy starting material comprising casein and whey proteinsis adjusted if necessary by addition of acid or alkali to a pH in the range 5.0-8.0.The pH adjusted material is then heat-treated to denature whey protein in thepresence of casein. This treated material is either retained or dried to forma powder or as a dairy concentrate. The product may be used in a method for forminga product such as a processed cheese, a processed cheese-like product, a spread,a yoghurt or a dairy dessert. In this method, the product is dissolved/suspended(if necessary) and undergoes pH adjustment to a pH in the range 4.5-6.5. The materialmay be cooked to form a molten mass which is subsequently cooled to form a milk proteingel.
