Vitamin A or precursor carotenoids

Vitamin A or precursor carotenoids with provitamin A activity
are poorly soluble in water and relatively unstable during food
processing and storage due to its chemical structure, which contains many double bonds susceptible of degradation. Further the
stability of vitamin A is also affected by acidity and at pH below 5.0
this compound is more easily destroyed. Trace metals (especially
iron and copper) and ultraviolet light accelerate the degradation of
vitamin A
