[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].

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.

[Comparative study on the essential composition content of commercial follow-up formula for young children with the requirements in the new national food safety standard in China from 2017 to 2022].

OBJECTIVE: To understand the distribution of the essential composition content of commercial follow-up formula for young children in China, to analyze the differences with the new requirements of national food safety standard, and to promote the implementation of the new national standard(GB 10767-2021). METHODS: The label information on the total of 483 follow-up formula for young children permitted from January 2017 to June 2022 were collected and recorded, the distribution of essential compositions were analyzed and compared with the new national food safety standard. RESULTS: Compared with GB 10767-2010, 23 essential compositions were revised in the new national standard, 2 new essential compositions, α-linolenic acid and carbohydrates, were required, and 8 minimum requirements and 4 maximum requirements were revised, 16 new maximum requirements were developed. The whole change of the new standard was major. Comparing with GB 10767-2021, there were 8 essential compositions in commercial products with 100% compliance rate and 9 with more than 95% compliance rate, the discordance rate of pantothenic acid, folic acid, vitamin C and Vitamin D was more than 20%, Vitamin D has the highest discordance rate 97.10%. CONCLUSION: Although the revision of the essential composition requirements in the new national standard is major, the compliance rate of almost essential compositions is high. A few of individual essential compositions in some commercial products cannot meet the new standards requirements, the main reason is those can not reach the increased new minimum requirements, especially on vitamin D.
