New national standard second stage milk powder

Stage 2 older infant formula milk powder is suitable for infants and young children aged 6-12 months.

Stage 2 and 3 milk powder in the old national standard both comply with the national standard "Formula for Older Infants and Young Children" (GB 10767-2010). The new national standard revision divides the standard into two parts - "Formula for Older Infants" (GB 10766-2021) and "Formula for Young Children" (GB 10767-2021), which are more detailed.

The specific changes in the new national standard for milk powder in Stage 2 include the following aspects:

1. Macronutrients

① The new national standard has added requirements for the proportion of whey protein. The whey protein content in stage 2 milk powder should be ≥ 40%. There is no relevant requirement in the old national standard.

Whey protein is a protein with small molecules and easy to absorb. The opposite is casein with large molecules. During the lactation period, the proportion of whey protein in breast milk will drop from 90% of colostrum to 60% of mature milk, and then to about 40% in the late lactation period.

Therefore, stipulating that the whey protein ratio of stage 2 milk powder is ≥40% is more in line with breast milk and is very necessary to help babies over 6 months old better digest and absorb the milk powder. of protein.

② The new national standard has increased the requirements for the proportion of lactose. The carbohydrate content of lactose in stage 2 milk powder should be ≥90%, and the source of carbohydrates should be lactose. At the same time, it is stipulated that fructose and sucrose should not be used as the source of carbohydrates in Stage 2 milk powder. Glucose polymers can be added appropriately (starch can be added after pre-gelatinization). The old national standard did not have regulations on the lactose content of stage 2 milk powder, nor did it limit the use of fructose and sucrose.

For normal babies under 1 year old (except for babies with lactose intolerance), lactose is the best source of carbohydrates among many sugars. It can promote brain development, Adjust the intestinal environment, reduce sweetness and other benefits. During the lactation period, lactose accounts for about 90% of carbohydrates in breast milk. Therefore, it is scientific and necessary to stipulate that the proportion of lactose in stage 2 milk powder is 90%.

③The new national standard has significantly lowered the minimum and maximum protein values ​​of stage 2 milk powder.

On the one hand, because the protein content in breast milk will decrease as the baby's weight increases. On the other hand, baby food supplements after 6 months will also be rich in protein.

④The new national standard fine-tunes the fat limit of milk powder in Stage 2, and also increases the limits of linoleic acid, α-linolenic acid, their ratio, carbohydrates, and soybean base Milk powder protein limit.
