COVER PHOTOGRAPH:

From the article of Evelyn B. Rodriguez et al. (2015), p. 382–391. Betalains are water-soluble, nitrogen-containing pigments that reportedly have disease-preventing and health-promoting properties, including antioxidant,  anti-inflammatory, anti-diabetic, phase II detoxifying enzyme-inducing and anti-cancer activities. Through encapsulation using combinations of carbohydrate biopolymers, the red-purple color of betalains can be protected and stabilized under various storage conditions, normal food processing temperatures, and various pH levels of food and biological systems. As a natural colorant, betalains from the peel of red dragon fruit [Hylocereus polyrhizus (Weber) Britton & Rose] can be developed as an alternative to synthetic food colorant.
