[Comparative study on the essential composition content of commercial infant formula with the requirements in the new national food safety standard in China from 2017 to 2022].

ABSTRACT

OBJECTIVE: In order to understand the distribution of the essential nutrients content in commercial infant formula in China, and to compare its conformity with the new national standard(GB 10765-2021). METHODS: A total of 477 infant fomulas with production data from January 2017 to June 2022 were collected in China. Information in the product labels was recorded and the distribution of nutrient contents was analyzed, compare with the national food safety standard. RESULTS: Compared with GB 10765-2010, the new standard had 12 essential nutrients content revised, and 10 of which had lower limit values adjusted and 5 of which had upper limit values adjusted. Both the lower and upper limits were increased for three items, including vitamin D, choline and selenium. Compared with the newly revised 12 essential nutrients in the national food safety standard, the coincidence rate of 3 items was 100%, and the coincidence rate of 3 items was more than 80%. The coincidence rate of the actual content of essential nutrients in some products was low, the reason was that they did not meet the lower limit requirements of the new national standard, for example, the non-coincidence rate of vitamin D was as high as 99.79%. In addition, the national food safety standard adjusts choline from an selectable nutrient to an essential one, and the proportion of choline added to commercial products was 84.7%. CONCLUSION: The change of the content of essential nutrients in the new standard has little influence on the products sold in our country. There are a few essential nutrient in the products on the market that need to be adjusted to raise the nutrient level.
