Acidifiers like citric acid are added to food to give them a refreshing, sour taste, as well as to optimise the acid content, to avoid discolouration, and to prevent the growth of unwanted microorganisms.

In nature, citric acid occurs not only in citrus fruit, but in all cells, where it performs vital functions in energy metabolism.

RITTER SPORT Strawberry Yoghurt and summer varieties contain citric acid. That is what makes them taste so fresh and fruity. It also emphasises their freeze-dried, real fruit pieces.
