Experiment 1-
In this experiment, I compared the Vitamin C content of 5 freshly squeezed fruit juices: pineapple, apple, lemon, orange, and grapefruit.
I observed that pineapple has the most Vitamin C, and Lemon has the least (out of these 5 fruits).
| Fruit | Ranking for Vitamin C content |
|---|
| Pineapple | 1st
|
| Orange | 2nd |
| Apple | 3rd |
| Grapefruit | 4th |
| Lemon | 5th |
Experiment 2-
In this experiment, I compared the amount of Vitamin C in concentrate juices to freshly squeezed juices.
| Freshly Squeezed Juice | Juice from Concentrate | More Vitamin C |
|---|
| Pineapple | Pineapple | Freshly squeezed |
| Orange | Orange | Freshly squeezed |
| Apple | Apple | Concentrate |
| Lemon | Lemon | Freshly squeezed |
The juices where the freshly squeezed has more Vitamin C, it has more by a very little bit. However, the apple concentrate juice took away all the dark purple-bluish color and it looked like water.
Also, the apple concentrate juice had more vitamin C than even fresh pineapple juice. Among all the juices, whether fresh or from concentrate, apple concentrate had the most vitamin C. It must be noted that the Apple concentrate was vitamin C fortified.
Experiment 3-
In this experiment, I compared the Vitamin C content of Cplus, Sunny D, and, Kool-aid.
| Drink | Ranking |
|---|
| Kool-aid | 1st |
| Sunny D | 2nd |
| C-plus | 3rd |
