An Underutilized Tropical Plant Psidium cattleianum (Strawberry Guava)

Abstract

Psidium cattleianum Sabine or strawberry guava is an exotic, tropical plant belonging to Myrtaceae family. This shrub bears prolific fruits, yet it is more recognized as an ornamental than an edible plant. Its emergence as an invasive spe-cies in Hawaii and defiance towards biological control agents has further lowered its desirability. However, recent findings have shed light on its food potential. It has been identified as a reserve of savory fruit and pectin. Copious phytochemicals have validated its antioxidant, antimicrobial and antiproliferative activities. This chapter presents an overview of its current status and prospect in functional food formulation.
