Which Fruit Has The Most Vitamin C Science Experiment
Introduction
Vitamin C is an essential nutrient that plays a vital role in the immune system. It is also an antioxidant that helps protect the body from damage caused by free radicals. Fruits are a great source of vitamin C, and it is important to know which fruit has the most vitamin C. This article presents a science experiment that tests different fruits for their vitamin C content.
Materials
The materials needed for this experiment are:
- Iodine solution
- Potassium iodide solution
- Starch solution
- Distilled water
- Test tubes
- Graduated cylinder
- Knife
- Cutting board
- Fruits (lemon, orange, kiwi, guava, strawberry, and papaya)
Procedure
The procedure for this experiment is as follows:
- Extract the juice from each fruit.
- Add 1 ml of each fruit juice to separate test tubes.
- Add 1 ml of distilled water to a test tube as a control.
- Add 1 ml of iodine solution to each test tube.
- Add 1 ml of potassium iodide solution to each test tube.
- Shake the test tubes to mix the contents.
- Add 1 ml of starch solution to each test tube.
- Measure the time it takes for the solution in each test tube to turn blue-black.
Results
The results of the experiment showed that the lemon had the most vitamin C, as it took the longest time for the solution to turn blue-black. The orange had the second most vitamin C, followed by the kiwi, guava, strawberry, and papaya.
Conclusion
In conclusion, the lemon has the most vitamin C among the fruits tested in this experiment. However, it is important to note that the vitamin C content of fruits can vary depending on many factors, such as ripeness, storage, and processing. Eating a variety of fruits can help ensure adequate vitamin C intake.
