This experiment will aim to find out whether fresh orange juice really does contain more vitamin C than those made from concentrate. S C I E N T I F I C Vitamin C (ascorbic acid) is water soluble and a strong reducing agent. Free lesson printable. 10 g/1000mL or 264 mg per 240mL serving, exceeding the daily value by 293% for men and 352% for women. The results show that the concentration of ascorbic acid (vitamin C) in the orange juice is 3. As consumers, we may sometimes wonder whether these tablets or juices contain the indicated amounts as claimed. 988mg/mL) was close to the class average (1. Jun 24, 2022 · Results The highest content of vitamin C immediately after pressing was observed in the juice of hand-squeezed oranges from the Salustiana variety. Sep 22, 2021 · You will need to bring a powdered or liquid drink, health product, fruit samples, or other commercial sample to lab for vitamin C analysis. Try testing pumpkin, lemons, squash, oranges. Key results include: - Orange juice had the highest concentration of vitamin C at 1. The indicator solution will change from a blue color to an intermediate pink/purple color, then to a colorless/very faint amber endpoint with the addition of ascorbic acid. 784 Jul 1, 2013 · Find out about vitamin C or ascorbic acid and try a short experiment to test for its presence using iodine in this article from our 'Avogadro's lab' series. - White grape juice contained 0.
