PHYSICAL AND CHEMICAL PROPERTIES OF THE JUJUBE FRUITS AT DIFFERENT MATURATION STAGES

The effects of maturation stages on some physical and chemical properties the jujube fruits were investigated. described as green, yellow, half-red red maturation. composition fruit significantly changed depending stage. size weight increased, peel color from green to with content water-soluble vitamins, trans-resveratrol, total phenolic antioxidant capacity decreased during trans-resveratrol was investigated for first time no could be detected at major organic acid sugar stage found malic sucrose, respectively. also changed, but these changes showed unstable trend compound catechin stage, whereas chlorogenic dominated is rich in minerals especially potassium mineral contents except copper observed between stages.
