Quality Evaluation And Effect Of Citric Acid Concentration On Fresh And Concentrated Pineapple (Ananas Comosus) And Watermelon (Citrullus Lanatus) Fruit Juices
ABSTRACT
Pineapple (Ananas comosus) Fruit Juices (fresh and
concentration) and Watermelon (Citrullus lanatus) Fruit Juices (Fresh and
Concentrated)were produced using 0.1% and 0.2% concentration of Citric Acid as
Preservative. Proximate compositions of the samples were investigated and the
results showed that the protein contents in Watermelon Fruit Juice
sarnples(4.30%,4.34%,3.23% and 3.84%) respectively were higher than the protein
contents (4.30%, 2.34%, 2.0 1% and 2.03% respectively) in Pineapple Fruit
Juice. pH and total soluble solids increased in the concentrated Fruit Juice
samples. The fresh Fruit Juice samples recorded higher Vitamin A content than
the concentrated samples .The Vitamin C content was higher in the concentrated
samples. The Antioxidant capacity was higher in the concentrated Fruit Juice
samples than the fresh Fruit samples. Stability test indicated that
Concentration Process and higher concentration of Citric acid lowered the
amount of Microbial invasion. Sensory analysis revealed that all the Fruit
Juice samples were generally accepted but Fresh Pineapple Juice sample treated
with 0.1% citric Acid (FPJO. I ),was the most preferred in terms of taste,
colour, aroma, flavour, Mouthfeel and general acceptability.
