How can we determine the concentration of vitamin C in fruit juice?
Measure the vitamin C content of a sample of fruit juice by measuring the volume of the sample required to decolourise a solution of DCPIP. Calibrate the results by comparison with a known concentration of vitamin C.
How do you test the amount of vitamin C in orange juice?
One way to determine the amount of vitamin C in juice is to use a redox titration. In a redox titration, one compound donates electrons to another compound. The compound losing electrons is oxidized and the compound gaining electrons is reduced.
How would you test for the presence of vitamin C in food?
Draw up some of the clear liquid into a pipette and then add it, one drop at a time, to a test tube containing a light blue solution of DCPIP. If the extract is acid the colour will change from blue to red. Continue to add more and see if the colour disappears altogether.
Does 100% fruit juice have more vitamin C than juice with artificial ingredients?
if the 100% fruit juice has more vitamin C then the juices with artificial ingredients will turn black because the artificial ingredients don’t have enough vitamin C. ingredients. The concentrated orange juice has more vitamin c then the other juice.
Which fruit has the most vitamin C research?
1. Kakadu Plums. The Kakadu plum (Terminalia ferdinandiana) is an Australian native superfood containing 100 times more vitamin C than oranges. It has the highest known concentration of vitamin C, containing up to 5,300 mg per 100 grams.
How do you calculate vitamin C content?
Calculation. For standard solution Mass Ascorbic acid = Mole iodine × Volume of iodine × 176.12 = 0.00231 × 45 × 176.12 = 91.54 mg Initially, the amount of Ascorbic acid was taken for 100mg and therefore for total amount of ascorbic acid i.e. 250 mg the ratio stands out to be 2.5 (250/100).
How do you measure vitamin C content?
Take a small (known) amount – 50 mL for example – of the vitamin C solution and add five drops of starch indicator. To your mixture of vitamin C and starch indicator, add drops of iodine, carefully counting the drops, until the solution develops a blue-black colour that does not disappear on stirring.
How do you test vitamin C in juice?
Does concentrated juice have more vitamin C?
Fresh juice typically has a leg up on juice concentrate because the juice can lose some of its vitamin content during processing. Juice from concentrate can also contain less vitamin C than fresh juice — fresh and concentrated orange juice offer 124 and 97 milligrams of vitamin C per serving, respectively.

One serving of 100 percent orange juice supplies 100 percent of the vitamin C that your body needs. Read the product label carefully, as a product may contain 100 percent of your daily vitamin C, but that does not mean the product is 100 percent fruit juice.
In which fruit is vitamin C present?
Raw citrus fruits are very high in vitamin C. One medium orange provides 70 mg of Vitamin C, while one grapefruit provides about 56 mg. Citrus fruit juices contain even higher amounts of vitamin C, with a 225 mg glass of orange juice providing around 125 mg of vitamin C.
How are vitamin C levels measured in juice?
VitaminC in Juice = 0.272mg/ml. Some Vitamin C science projects and experiments you can do using this method: Measure Vitamin C concentration in different juices from the grocery store, compare the results with concentrations indicated on the juice labels. Measure concentration of vitamin C in different fruits.
What was the objective of the vitamin C experiment?
