Vitamin C Content
OBJECTIVE
To investigate the vitamin C content of different fruit juices.
To identify which fruit juices has higher vitamin C content and the lowest vitamin C content.
To determine the standard curve of vitamin C based on percentage of vitamin C.
To differentiate between fresh juices and carton juices.
To consider the reliability and validity of the results.
PROBLEM STATEMENT
Which type of fruit juices has the most vitamin C content?
HYPOTHESIS
The smaller the amount of the fruit juices to decolourise DCPIP solution, the higher vitamin C content in the fruit juices itself.
The fresh orange juice gains the highest vitamin C content than other juice (carton juice, fresh lime and fresh lemon).
NULL HYPOTHESIS
All type of fruit juices has the same value of vitamin C content.
VARIABLES
Manipulated Variable: Type of fruits juice used
Responding Variable: Volume of Fruit juices decolourise DCPIP solution
Control Variable : volume of DCPIP solution, Concentration of DCPIP solution,
INTRODUCTION
Vitamins are organic compounds that are required in very small amounts (micronutrient compound) for maintaining good health. Vitamins are not energy providing foods. Vitamins are divided into water soluble vitamin and fat soluble vitamin. Water soluble vitamin include vitamin B and vitamin C while fat soluble vitamin include Vitamin A, Vitamin D, Vitamin E, and Vitamin K.Every Vitamin that we consume has its ability to function well in our body system which acts as supplement for our health. Diagram 1.1 show structural formula of ascorbic acid.
Vitamin C is one of the quite famous vitamins among the vitamins. Due to the presence of vitamin C content in majority of fruits such as lemons, oranges, limes. Vitamin C also known as Coenzyme Q10 (CoQ10) which is disturb the activity of the free radical. Free radical can affect the cell membrane by alter it and change the structure of DNA.Free radical can increase risk of many health problem such as cancer and
