Adulteration can take many forms but one commonly investigated is C4 adulteration in honey. Honey adulteration can occur when bees are fed high fructose corn syrup or cane sugar instead of making honey from foraged nectar, or the honey is diluted with these products post-harvest. This form of adulteration can clearly be detected using an AOAC accredited method.
Fruit juice testing is carried out in a similar manner, using isotopic water signals to discriminated fresh fruit juice from those made from concentrate.
