ABSTRACT
This study was performed to evaluate the nutritional and microbiological quality of industrially processed packed fruit juices of mango (Mangifera indica) and orange (Citrus sinensis) from nine different manufacturing companies in Dhaka City. The highest quantity of total sugar (17.62%) and reducing sugar (9.99%) was recorded in mango juices while the lowest in orange juices (10.41% and 2.24% respectively) of different companies. In this study, protein contents were comparatively higher in mango juices than in orange juices. The pH of all samples varied from 3.50±0.10 to 4.70±0.05. Vitamin C content was comparatively higher in mango juices. The levels of metals tested namely, arsenic, lead, copper and zinc in the juices were within the limits of Bangladesh Standard and Testing Institute (BSTI) for fruit juices. The microbiological qualities of all the products were within the limits of the Gulf standards (the recommended Microbiological Standards for any fruit juice sold in the Gulf Region). Based on the above results, it is suggested that processed juices be prepared under hygienic conditions.
