Abstract: The function of health food is mainly determined by its functional ingredients. And its detection method is closely related to the quality of health food product. This paper sorts out the main functional claims,functional ingredients and corresponding detection methods of 4620 kinds of health food registered and filed in 2013~2020. 121 kinds of functional ingredients and their functional claims and detection methods are summarized. There are so many functional claims for each functional ingredient. The main functional claims of each functional ingredient should be clarified. At the same time,it is found that the functional ingredients detection standards system of health food in China are relatively integrity. At present,only 5 kinds of functional ingredients with high market recognition need to establish the standards for the detection,such as xylooligosaccharide,total triterpenoids,total anthraquinone,heme chloride,and total glycosides of cistanche deserticola. In order to improve the functional ingredients standard system of health food,this paper not only clarifies the work requirements,but also points out the development direction for more targeted function claims of functional ingredients and the development of corresponding detection method standards,which is conducive to promoting the healthy and sustainable development of health food industry in China.
