ABSTRACT
Guava is a delicious tropical fruit having a eshy, yellow ovoid berry about 5 cm in diameter with an edible pink mesocarp containing numerous small hard white seeds [1]. The name “guava” usually refers to Psidium guajava L., which is the most common guava species of the genus “Psidium.” Indeed, there are 150 other guava species, among which “cattley guava” (P. cattleianum Sabine), “pear guava” (P. pyriferum L.), and “apple guava” (P. pomiferum L.) species are the most important [2]. Guava, which is native to Mexico, the Caribbean, Central America, and the northern part of South America, grows well in all tropical and many subtropical regions [1]. India is the leading guava producer country followed by China. These two countries accounted for about 60% of global market share in 2012 [3].
