Problems solved by technology

[0004] At present, bifidobacteria have been gradually added to the food of infants and young children. However, bifidobacteria are anaerobic bacteria and are extremely sensitive to the water activity of the product, so that they attenuate extremely during the processing and shelf life of the product. The product does not meet expectations

preparation example Construction

[0035] The invention provides a kind of preparation method of infant formula milk powder, comprises the following steps:

[0036] A) adopting wet process to prepare the base powder with water activity≤0.18;

[0037] B) dry mixing the base powder, auxiliary materials and probiotics to obtain formula milk powder for infants and young children, the condition of the dry mixing is to vacuumize and fill with N 2 , Residual oxygen <3%.

[0038] The invention firstly adopts a wet process to prepare the base powder with water activity ≤ 0.18.

[0039] The present invention optimizes the control of the wet process and improves the packaging material. The inner packaging material is 5-layer high-barrier co-extrusion film EVOH-PE170 to package the base powder, so as to ensure that the water activity of the base powder can be controlled below 0.18 before use and mixing.

[0040] Specifically, the base powder is prepared according to the following method:

[0041] 1) Raw milk, purified w...

Abstract

The invention provides a preparation method of infant formula milk powder. The preparation method comprises the following steps: A) preparing base powder of which the water activity is less than or equal to 0.18 by adopting a wet process; and B) enabling the base powder, auxiliary materials and probiotics to be subjected to dry mixing, to obtain the infant formula milk powder, wherein the dry mixing condition is that N2 is introduced through vacuumizing, and the residual oxygen is smaller than 3%. Firstly, infant formula milk powder base powder with the water activity being 0.18 or below is produced by adopting the wet process, and then the base powder, the auxiliary materials and the probiotics (Bifidobacterium animalis Bb-12) are subjected to dry-mixing under a low-oxygen condition (specifically under the conditions of vacuumizing and filling inert gas N2 and residual oxygen being less than 3%) to obtain the infant formula milk powder suitable for babies of different month ages. The stability of the probiotics in the production process and the shelf life of the product is ensured, and the attenuation rate of the shelf life of the product is controlled within 10%.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to a preparation method of formula milk powder for infants and young children. Background technique [0002] Breast-fed infants have been colonized with bifidobacteria since 2 days after birth, and gradually surpassed E. coli to become the dominant bacteria in 4-5 days, accounting for more than 95% of intestinal microorganisms. The greatest difference between the microbiota of breastfed and formula-fed infants is the number and composition of bifidobacteria. The concept that probiotics are beneficial to intestinal health and improve immunity has been widely accepted by consumers. According to online research data, in recent years, probiotic or prebiotic food and beverages have been launched on the market far faster than the speed of the previous five years. The formula milk powder added with bifidobacteria sold in the domestic market is also rapidly occupying the core area...
