How do scientists know which vitamins are found in different foods?
Typically, chromatography is used to determine what vitamins are present in certain foods. This technique uses a long thin tube filled with a particulate packing material through which gasses or fluids flow. When a "sample" in injected in one end, it begins to flow through the tube. Each different chemical structure in the sample flows at a unique rate, based on its subtle interactions with the packing material.
