Science Fair Project Vitamin C test
When one thinks of Vitamin C, pictures of oranges usually come to mind. That’s because vitamin C is highly abundant in citrus fruits such as oranges, lemons, limes, and grapefruits. Does Juice made from these fruits naturally have more Vitamin C than artificial fruit Juices? In this experiment, we will be using three different kinds of orange Juice: “From concentrate” “Not from concentrate” and “Orange-flavored drink”.
We will determine which, out of all these Juices, has more Vitamin C. To know what juice has more Vitamin C, I created an “Iodine Indicator” by simply boiling water with cornstarch for approximate 5-10 minutes depending on the heat. Then I added some mixture into a test tube and combined it with the decided Juice and repeated it until I finished with all the Juices. After I finished I compared all the mixtures and saw which one was the darkest which meant It would have less Vitamin C.
The Juice that seemed to have most Vitamin C was “From Concentrate”, followed by “Not-From Concentrate” and finally “Artificial flavored Juice”. I tested this 5 times. In which I got the same results on most of them, but 1 of them had a different conclusion the “Not-From concentrate” came out on top and “From Concentrate” second and finally “Artificially flavored Juice” In conclusion, we determined that “Artificial flavored Juices” have less Vitamin C, than 100% natural Juices.
