Fromtheobtainedresultsthecarbohydratecontent,bothin the water melon, orange and guavafruitsandthepretreatedOrangehada highercontent(0.0717 /34%), followed by Watermelon (0.0425/20%), and Guava which is recorded 0.02140/10% (mg/l). Similarly all samples were found acceptable for human’s consumption from microbial point of view and fall in the range of WHO standards absorption. This research finding provides useful information for preparation and implementation in national policies and for updating Nigeria food act and regulations to improve the quality of foods and drinks in Nigeria thus improving the health condition of the community.
