How do you measure the amount of vitamin C in juice?

Answer 1

we can measure the amount of vitamin C in juice through of samples and then we need to make tests analyzing the ozidizing agents...

my answer will be.....

1. Mix 1 tablespoon of cornstarch into enough water to make paste.

2. To this paste, add 250ml of water and boil for 5 minutes.

3. Add 10 drops of the starch solution to 75 ml of water (use an eyedropper).

4. Add enough iodine to produce a dark purple-blue color. Now your indicator solution is ready.

5. Put 5ml of indicator solution (about 1 tablespoon) in a 15ml test tube. To the test tube, use a clean eyedropper to add 10 drops of juice. Re-clean the eyedropper for each sample.

6. Hold the test tube against a white background. Line up the tubes from lightest to darkest purple. The lighter the solution, the higher the vitamin C content. That's because vitamin C causes the purple indicator solution to lose its color.

this is the solution about how you measure the amount of vitamin C.....

actually.....i think mine is better than the one at the top tee hee

Answer 2

Procedure to test for vitamin C content. (With this method, you can compare relative vitamin C content and rank foods from highest to lowest, but you won't be able to get exact concentrations.)

You'll need some 2% iodine solution (find it at your local pharmacy) to prepare the vitamin C indicator solution described in steps 1 to 4.

1. Mix 1 tablespoon of cornstach into enough water to make paste.

2. To this paste, add 250 milliliters of water and boil for 5 minutes.

3. Add 10 drops of the starch solution to 75 milliliters of water (use an eyedropper).

4. Add enough iodine to produce a dark purple-blue color. Now your indicator solution is ready.

5. Put 5 milliliters of indicator solution (about 1 teaspoon) in a 15-milliliter test tube (one for each sample).

6. To the test tube, use a clean eyedropper to add 10 drops of juice from the fruit or beverage (for solids, pulp them in a blender and strain the juice). Re-clean the eyedropper for each sample.

7. Hold the test tube against a white background. Line up the tubes from lightest to darkest purple. The lighter the solution, the higher the vitamin C content. That's because vitamin C causes the purple indicator solution to lose its color

Answer 3

depends on the organ I suppose... the liver will probably have the most but be careful of toxins and laws stating you cannot consume organs.

Answer 4

Take a blood sample.
