ABSTRACT
Fruit drinks are suggested as the most appropriate replacement for fresh fruits. This research involves comparative assessment of nutritional and anti-nutritional ingredients found in local and branded juices. Seventeen samples of local and branded juice varieties were obtained from Hyderabad city local market. Three kinds of mango, apple and oranges were checked for their total phenolics (TPC) and total flavonoids (TFC) using the colorimetric technique and folin-Ciocalteu method. Other analysis included protein estimation by bradford method, metals (Fe, Zn) analysis by atomic absorption spectrophotometry and vitamin c analysis by titration method. Results depict that total protein was quite high in B1 orange juice, total phenolics and total flavonoids are significantly high in L3 orange juice among all the tested juices. Higher content of iron was found in L1 variety of apple and mango juice whereas B3 depicted increased iron levels among orange juice varieties. Higher zinc levels were found in Apple (B1) and Orange (B2 and L3) juice. Anti-nutritional component tannin was present in low amount in most of the selected juices, however, branded apple juice (B3) depicted higher tannin amount as compared to other juices. The study illustrates that those local juices which were seen to retain all nutrients and antioxidants can be replaced with branded juices as per consumer’s affordability.
