In order to ensure that the product meets consumer expectations, synthetic colors are often added to food and beverages. The addition of these synthetic colors helps to offset the natural color loss caused by exposure to light and temperature/ moisture loss. They also assist to standardise natural color variation, enhance weak color hues in a product, or simply create a fun look for a food or beverage.
Although synthetic colors are considered to be more stable compared to their natural counterparts, some of them are still prone to color fading due to light exposure. Furthermore, more and more companies are converting from artificial colors to natural colors, both from a technical and commercial point of view.
