Objective : To compare the types and quantities of carbohydrate, electrolytes, pH and
osmolarity of fresh fruit juices and commercial fruit juices.
Material and Method : Forty kinds of fresh fruits available in Thai markets were analyzed
for types and quantities of carbohydrate, electrolyte, pH and osmolarity and compared with pre-
viously obtained data for commercial fruit juices.
Results : Most fresh fruit juices did not contain sucrose, whereas, commercial fruit juices
mostly have sucrose in the range of 3-112 giL. Although both fruit juices were acidic (pH varied from
3.6-6.7 and 3.2-5.8 of fresh juice and commercial juice), fresh fruit juices had a more neutral pH
than commercial fruit juices. Apple, guava, orange, pear, and pineapple juices from commercial
fruit juices had a high osmolarity compared with fresh fruit juices. All types of fresh fruit juices
contained less sodium than commercial ones, whereas, most fresh fruit juices contained more potas-
sium, phosphorus, and magnesium than commercial fluids.
Conclusion : The nutrient content of fresh fruit juices and commercial fruit juices from the
same kinds of fruits are not the same, possibly due to the manufacturing process. Therefore, physi-
cians should know the composition of fruit juices in order to advise patients properly.
