Which Orange Juice Has The Most Vitamin C Science Project
Introduction
Orange juice is one of the most commonly consumed beverages in the world. It is a rich source of vitamin C, which is essential for maintaining a healthy immune system. However, not all orange juices are created equal when it comes to their vitamin C content. In this science project, we will investigate which orange juice has the most vitamin C.
Background
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that is essential for the growth and repair of tissues in the body. It is also important for the production of collagen, a protein that helps to keep skin, bones, and joints healthy. Vitamin C is found in many fruits and vegetables, including oranges.
Hypothesis
Our hypothesis is that fresh orange juice will have the most vitamin C, followed by frozen orange juice concentrate and then pasteurized orange juice.
1. Squeeze fresh oranges to obtain 100 ml of fresh orange juice.2. Measure 100 ml of frozen orange juice concentrate and dilute it with 100 ml of distilled water.3. Measure 100 ml of pasteurized orange juice.4. Pour each type of orange juice into a separate beaker.5. Add 10 ml of iodine solution to each beaker.6. Add 10 ml of starch solution to each beaker.7. Use a pipette to mix the solutions in each beaker.8. Pour each mixture into a separate test tube.9. Shake each test tube vigorously.10. Observe the color of each mixture.11. The mixture that turns blue-black in color indicates the presence of vitamin C.12. Record the results.
Results
The fresh orange juice turned blue-black in color, indicating the presence of vitamin C. The frozen orange juice concentrate also turned blue-black in color, but the pasteurized orange juice did not.
Conclusion
Our hypothesis was partially correct. Fresh orange juice did have the most vitamin C, but frozen orange juice concentrate was a close second. Pasteurized orange juice had the least amount of vitamin C. It is important to note that the vitamin C content of orange juice can vary depending on the type of orange, the ripeness of the fruit, and the processing method.
