STUDY OF NUTRIENT VALUE IN POST HARVESTED INFECTED ORANGE (CITRUS SINENSIS) FRUIT

Abstract

Orange (Citrus sinensis) is a very nutrient and beneficial fruit all over the world. Study wereconducted on changes in the nutrient value like reducing sugar, non reducing sugar, starch, protein,phenol, vitamin C, alpha-amylase and total antioxidant activity of the post harvested infected orangefruit. In this analysis two fungi were isolated from infected orange fruits. The effect of these fungiindicate the reduction in non-reducing sugar, vitamin C, alpha-amylase and antioxidant activity butthe amount of reducing sugar, protein and phenol increased in infected fruit. The nutrient valuedeclined or increased due to the infection of penicillium and phytophthora fungus. From the presentinvestigation it can be concluded that the fungus decrease or increase the nutrient value of fruitbecause they use them for their successful growth and establishment.
