Which Orange Juice Has The Most Vitamin C Experiment
Oranges are known for being rich in vitamin C, which is essential for a healthy immune system. However, not all orange juices are created equal when it comes to vitamin C content. In this experiment, we will compare the vitamin C levels of different brands of orange juice to determine which one has the most vitamin C.
Materials
- Three different brands of orange juice
- A juicer
- A lemon juicer
- A measuring cup
- A bowl
- A funnel
- A graduated cylinder
- Iodine solution
- Starch solution
- Distilled water
- A stopwatch
- A pipette
- A test tube
- A dropper
Procedure
1. Wash your hands before starting the experiment.
2. Squeeze the juice out of each orange using a juicer.
3. Use a lemon juicer to extract as much juice as possible from the leftover pulp.
4. Pour each type of orange juice into a separate bowl.
5. Measure out 50 mL of each juice using a measuring cup.
6. Pour each sample of juice through a funnel into a separate graduated cylinder.
7. Add 1 mL of iodine solution to each sample of juice.
8. Add 1 mL of starch solution to each sample of juice.
9. Add distilled water to each sample of juice until the total volume is 100 mL.
10. Mix each sample thoroughly with a dropper.
11. Start the stopwatch and wait for the juice to turn blue-black.
12. Use a pipette to transfer 1 mL of each sample into separate test tubes.
13. Add 1 mL of distilled water to each test tube.
14. Mix each test tube thoroughly with a dropper.
15. Start the stopwatch and wait for the solution to turn clear.
16. Record the time it takes for each sample to turn clear.
Results
The time it takes for the solution to turn clear is directly proportional to the amount of vitamin C in the orange juice. The faster the solution turns clear, the more vitamin C the juice contains. Here are the results of our experiment:
- Brand A: 40 seconds
- Brand B: 30 seconds
- Brand C: 20 seconds
Conclusion
Based on our experiment, Brand C has the most vitamin C content, as it turned clear the fastest. Brand A had the least vitamin C content, as it took the longest time for the solution to turn clear. Brand B was in the middle, with a moderate amount of vitamin C. Therefore, if you want to get the most vitamin C out of your orange juice, go for Brand C.
