Updating [Nutritional composition dataset of approved infant formula powder in China (2017-2024)] with [Nutritional composition dataset of approved older infant formula powder in China (2017-2024)].

Older infant formula powder, which can meet some of the nutritional needs of infants aged 6 to 12 months, is suitable for normal older infants. In this context, China has established a stringent registration-based regulatory system for infant formula products, requiring mandatory pre-market approval and comprehensive evaluation of all formulations before commercialization. The primary objective of this dataset was the comparative profiling of nutrient content in domestic and imported older infant formula products. The complete registration dossiers of 786 older infant formula powder from 2017 to 2024, officially disclosed on the Special Food Information Query Platform of China's State Administration for Market Regulation (SAMR) were systematically retrieved and collected, and verified by the nutritional values on the product packing or on the websites of the different brands. The nutritional values are systematically presented for 100 kJ and 100 g of powder. The nutrient content in domestic and imported were also statistically calculated and presented, the analysis revealed general compliance with national standards with minor variations between domestic and imported products. This dataset can be applied as a tool for data-driven insights for older infant formula optimization, aligning with China's updated national standards for precise dietary management, or to assist Chinese consumers in selecting appropriate older infant formula milk powder products.
