Abstract: A method for preparing a yoghurt is provided. The method comprises (a) preparing a calcium-depleted milk composition comprising either (i) calcium-depleting a starting milk composition, or (ii) including within a starting milk composition a calcium-depleted milk ingredient selected from milk, fat standardised milk, skim milk, or milk concentrate; and (b) acidifying the calcium-depleted milk composition with chemical acidification or lactic acid producing bacteria, to prepare a yoghurt, wherein the calcium depletion is by contacting the milk composition or ingredient with a cation exchanger to replace calcium in the composition or ingredient with sodium or potassium.
