How to test for vitamin C:
1. Draw up 2cm3 of lemon/Orange Juice (or the substance you're wanting to test for vitamin C) into a syringe.
2. Add it drop by drop into 2cm3 of a 0.1% solution of DCIP (a blue dye)
3. The dye will turn colourless if vitamin C is present

Yes it does (I know because i did the test on orange juice) The more Vitamin C something has in it the less drops of that thing (in my case the orange juice) is needed for the DCPIP to go pale yellow. It is an awesome test! I would try it ( only if you have DCPIP and lots of different types of orange juice! Of course!)
A whole orange contains vitamin C and not just the inside of it. So when you make fruit juice and use only the inside part of the fruit, it is essentially not getting all the vitamin C out of the orange. And you don't always get all of the inside of the orange either, so there are bits and pieces that contain the vitamin that you won't get when making orange juice.
Orange juice, of course
