Sugar, Vitamin C, And Mineral Contents In Indigenous And Foreign Fruit Juices Marketed In Nigeria

Abstract

The Sugar, Vitamin C and Mineral contents in some indigenous and foreign fruit juices marketed in Nigeria were investigated. Some indigenous fruit juices namely Chivita pineapple, Funman orange, Delight orange and Tampico orange, while foreign fruit juices, such as Pure Heaven, Five Alive, Don Simon and Just Juice, were used. Total Acidity, pH, Sugar, Mineral, Vitamin C contents and organoleptic attributes were evaluated in these indigenous and foreign fruit juices.

Results of the study show that there were no significant (p<0.01) differences in the total acidity, pH and sugar contents in the indigenous and foreign fruit juices. The concentration of Vitamin C and minerals (K⁺, Na⁺, Ca²⁺, and Mg²⁺) in the foreign fruit juices were significantly (p<0.01) higher than in the indigenous fruit juices. Chivita pineapple was best preferred and closely followed by Just Juice, while Don Simon was least preferred.

Data of the study indicate that both indigenous and foreign fruit juices are good sources of energy, Vitamin C, minerals and water. They are found nutritionally adequate and acceptable for human consumption.

Key words: Sugar, Vitamin C, Minerals, Indigenous and Foreign Fruit Juices.
