Aging, storage conditions,and processing of foods cause vitamin loss, which varies widely
depending on the type of food and a number of specific parameters
(e.g., temperature, oxygen, light, moisture, pH) [2]. In the case of honey, has been shown that commercial filtration reduces its vitamin content due to the almost complete removal of pollen.
Another factor that causes the loss of vitamins in honey is the oxidation of ascorbic acid by hydrogen peroxide produced by glucose oxidase
