ACKNOWLEDGEMENT
This project was done with the aid of a lot of people. I take this chance to express my gratitude to Mrs. Hamidah Bt. Ahmad for the guidance and motivation that contributed tremendously to this project. My thanks and appreciations go to my friends in developing this project too.
TITLE
Analysis of Vitamin C in fresh brand orange, pineapple and apple juices.
ABSTRACT
Vitamin C plays an important role in our daily lives as a nutrition for our health. Tropical brand pineapple juice, Twister brand apple juice and Twister orange juice were used to determine for their concentration of Vitamin C contained. The concentration of Vitamin C contained of these fruit juices were identified by using titration. Based on the results, the concentration of Vitamin C contained in these 3 fruit juices were obtained. The conclusion of the experiment is that different fruit juices contain different concentration of Vitamin C which is important in our daily lives.

1.0 INTRODUCTION
1.1 THEORY/LITERATURE
Vitamin C is an essential nutrient in humans as it functions as a cofactor in several vital enzymatic reactions.(1) It is widely known that deficiency of Vitamin C would lead to scurvy in humans. Vitamin C also has other beneficial effects to our body, such as preventing common cold/heart diseases and strengthening human immune system.(4) However, human beings cannot synthesis Vitamin C by themselves and should obtain it from other sources. The richest natural sources of Vitamin C are fruits and vegetables, for example, blackcurrant, blueberry, orange, lime, lemon, strawberry, cabbage and malt. It is noted that Vitamin C can be chemically decomposed under certain conditions, such as heating and oxidation, many of which may occur during the cooking of food.(2)
In general, the recommendation for vitamin C intake in humans is around 60–95 milligrams per day and the maximum upper intake level is 2000 milligrams per day. Vitamin C exhibits remarkably low acute
