This reaction occurs when reducing sugars and amino acids are present together at high temperatures, leading to the formation of pigmented compounds that produce the purple or mauve color.
Hibiscus tea, also called roselle tea, is an herbal tea made from the hibiscus sabdariffa (or roselle) plant. It has a deep reddish purple color and a tangy flavor. Hibiscus is a common ingredient in herbal teas, where it imparts both a purple color and a tangy quality.
