Nutrition Science Fair Project?

Post autor: Braxton » pt maja 18, 2018 11:55 am

Hi,

I'm interested in doing a food-related project for the science fair this year, and have thought of comparing the nutritional benefits of organic vs. inorganic citrus fruits.
I have several questions:
1) Is it possible to measure the exact amount of fiber in a particular food? If so, how?
2) What about measuring vitamin or mineral content in a fruit? I'm aware of the awfully cliché vitamin C thing, but what about vitamins A,E,B,D, etc., or iron and zinc?
3) Could you give me a basic description of paper chromatography?

Please help.

I did not find the right solution from the internet.
