The Science Behind Blue Color in Foods: Natural vs. Artificial Blue color can be achieved naturally and artificially. Natural blue foods often contain pigments called anthocyanins. These compounds are found in blueberries, blackberries, and purple cabbage, giving them their blueish hue.

However, when cooked, it turns brown. While blue-colored seafood is not joint, other seafood like salmon and trout offer a rich source of healthy omega-3 fatty acids.
Blue Desserts and Beverages: Popular Choices and Ingredients Blue desserts and beverages often get their color from food coloring. Blue velvet cake, blue raspberry ice cream, and blue cocktails are famous examples. Ingredients like blue curaçao liqueur, blue spirulina, and natural butterfly pea flower extract achieve vibrant blue hues.

Additionally, plant-based blue dyes derived from sources like spirulina are gaining popularity as alternatives to artificial colorants.

In some cultures, blue foods are used in traditional dishes or celebrations. In Mexican cuisine, blue corn masa makes tortillas and tamales.
