Abstract

This study was carried out on tetra pack mango juices to analyze for selected physicochemical
analysis that included pH, acidity, 0
brix and total sugar. These samples were also analyzed for
sensory evaluation i.e. color, taste, appearance and smell. This research was carried out in the
Department of Food Science and Technology, Agriculture Research Institute (ARI), Swat.
Different brands of mango juice were purchased from local market of Swat that included
Pepsico, Enjoy, Tops, Nestle, Kool and Tropico. These brands were analyzed and the results
were recorded. The physicochemical analysis of these samples were as; Brad A (Pepsico) pH
3.73, acidity 0.27 %, 0brix 12.9, and total sugar 10.4%. Brand B (Enjoy) pH 4.20, acidity
0.13%, 0brix 9.8 and total sugar 2.17%. Brand C (Tops) pH 4.03, acidity 0.19%, 0brix 5.1 and

pH 4.05, acidity 0.18%, 0brix 6.5 and total sugar 5.37%. Brand (A) got highest scores in
sensory as well as in physicochemical analysis, comparatively, it is considered as the best mango
juice i the local market, while brand C and F were below the stadard limits of Pakistan Pure Food
