Romanian vegetable market offers to the consumers, fresh and preserved fruits and vegetables from Romanian production and import, and only preserved fruit juice. The quality of all products depends of many factors, such as: variety, geographical characterization of the plantation, presentation (fresh or preserved) and the market season. For our study we tested some fresh fruits juices, obtained into laboratory, from Romanian hypermarket fruits. Thus, we analyzed the concentration of ascorbic acid, the total acidity, the content of sodium chloride, dry matter and humidity, ash, and the content of saccharose. For fresh juice we used fresh grapefruits, tangerines, oranges, pineapple, and Golden delicious apples.
