Many foods, which are claimed to be functional such as "improving sleep" and "antioxidative property", are sold. These functions are based on "ingredients delivering function (functional ingredients)" and "content of the functional ingredients" in the food.
For claiming the function of food, identity and content of the functional ingredient must be demonstrated to be correct and accurate.
In addition, for products such as dietary supplement composed of functional ingredient concentrate, the functional ingredient must be demonstrated to adequately disintegrate and dissolute at an appropriate site in the body, exerting the function properly as claimed.
Fujifilm Wako has a large assortment of analytical standards and analytical kits of functional ingredients, which are needed for identification test in functional food development.
