Colors always play a significant role in our lives, influencing our perceptions, emotions, culinary choices, and appetite of course. In a wide spectrum of colors, blue holds a special spot, triggering the feeling of tranquility and serenity.

This article will explore the elusive world of blue food, and delve into the mystery behind their rarity. 

Why Is Blue Colored Food Rare? 

Unlike the prevalent colors like green, red or yellow, blue-colored food is rare in nature. The rarity of blue color can be attributed to the limited presence of blue pigment in plants. Instead of blue color, chlorophyll, and carotenoids are found abundantly in vegetables and fruits, giving them a greenish or orange to yellowish appearance. 

What Is the Secret Behind the Blue Food? 

The blue color of the food is due to the presence of the unique pigment “anthocyanin”, belonging to the flavonoid family. However, the color of anthocyanin depends upon the pH of the environment, playing a significant role in the rarity of naturally occurring blue food. For instance, in acidic conditions, it appears to be a purple or red color whereas in alkaline conditions it will manifest as a blue color.
