What are Starch-based ingredients? There is a wide range of ingredients made from starch. These starch-based ingredients have many different uses and perform multiple functions, depending on the way they are made and used. Some are used to add thickness to sauces, soups and deserts; others to add sweetness, preserve colour or flavour; others again to keep texture or prevent crystallisation when the products are frozen and reheated. Some starch-based ingredients are also low caloric alternatives for sugar, with recognised benefits on weight management, glycaemic control and dental health.
