Since these products are generally refrigerated or frozen and are usually protected from light, a wide array of natural colours for dairy can be used. The main stability considerations for choosing a natural colour in dairy are pH, heat from pasteurisation, and added flavours. At a neutral pH, spirulina, turmeric, emSeal® beta-carotene, annatto, and beet work well and provide a variety of colour options in the yellow to orange and pink to red range. Care should be taken when using anthocyanins. As the pH of a product becomes neutral, anythocyanins will shift from red to purple and may fade over time.

As cultures are introduced for yoghurt-based beverages, such as kefir, the pH is lowered, opening the door to fruit or vegetable-based anthocyanins like Amaize® red, red radish, and purple sweet potato that won’t grey as readily as they would at a neutral pH.
