[Study on the distribution of nutrient content in infant formula of China market].

Objective: To collect the infant formula products in China, determining the nutrients content and analysing the distribution of the nutrients in the products.

Methods: Infant formula products( domestic production or import) in China market were collected from shopping malls, supermarkets, maternal and infant shops, production enterprises and so on. Nutrients content in the products were determined using GB methods. The status of the nutrient distribution was analyzed, and also compared with the limits of the national standard.

Results: A total of 1639 cases of infant formula products bought from 27 provinces( Guangdong, Hebei, Heilongjiang and Inner Mongolia, etc. )were included in this study, and the products were domestically manufactured or imported from the United States, Europe, Australia, Japan, Singapore, etc, covering the main products in China market. Nutrient analysing results showed that the content ofcarbohydrate, vitamin A, vitamin E, vitamin K_1, vitamin B_1, vitamin B_2, vitamin B_6, folic acid, pantothenic acid, vitamin C, sodium, potassium, magnesium, calcium, zinc, manganese were in the lower area of GB limits, while the content of linoleic acid and iron were distributed in the higher area, and the content of protein, fat, vitamin D, niacin, copper distributed uniformly between GB limits.

Conclusion: Most nutrients in the infant formula products of China market are in the lower area of GB limits, so decreasing the upper limits of some nutrients according to the newest scientific evidence will not have too much impact to the current products.
