Vision is the most advanced among the five senses. If we currently aim to create mango-flavored pastries and make one white and the other yellow, consumers are more prone to purchase the one with the yellow color as yellow leads consumers to associate it more with the rich mango flavor.

Wang Bei, the deputy dean of the School of Food and Health at Beijing Technology and Business University, stated in an interview with China Consumer News that during food processing and cooking, due to temperature variations, water loss or mechanical damage, endogenous natural pigments will undergo certain alterations, which might cause food to change color, fade or even become pale. Color changes, such as the "Browning" (darkening or turning brown) that occurs during the processing of fruits and vegetables, do not appear very appealing. Therefore, the food industry has to contemplate, when necessary, by adding food coloring - coloring agents to improve the deterioration of the natural color of food caused by processing, "repair" and enhance the sensory attributes of food, so that consumers have psychological pleasure and the desire to purchase when confronted with food.

If one desires to make the product safer, healthier and more in line with the consumption concept of modern consumers, natural pigments are the sole option for adding color to food.
