Embodiment 1

[0032] Embodiment 1: the selection of sialic acid addition amount:

[0033] According to the content of sialic acid in human milk. The experiment of adding sialic acid by dry method was divided into 7 content gradients. According to the standard of infant formula milk powder produced by Wyeth, Mead Johnson, Nestle and other companies when preparing: 100mL liquid milk ≈ 14.1g infant formula milk powder + 90mL water, therefore, each liter of liquid milk contains 141g infant formula milk powder. Table 1 shows the addition amount of sialic acid dry added in infant formula milk powder.

[0034] Table 1 Addition amount of sialic acid infant milk powder produced by dry method

[0035]

[0036] According to data, the content of sialic acid in human milk is 250-1550 mg / L, and the standard for the content of sialic acid in infant formula milk powder is set as 300-600 mg / L in the US patent. From figure 1 It can be seen from the figure that when the dry method is added, the content...

Embodiment 2

[0038] Example 2: Inspection of sensory indicators of dry method added sialic acid infant formula milk powder

[0039] The sensory index detection was carried out on infant formula milk powder with dry method added sialic acid and infant formula milk powder with the same formula except sialic acid without adding sialic acid. The test results are shown in Table 2.

[0042]

Embodiment 3

[0044] (1) Skinning the raw materials;

[0045] (2) Add 2.8g / kg sialic acid to the raw materials and mix them. The ambient temperature of the mixture is below 20°C and the humidity is below 60%;

[0046] (3) Adjust the loading factor of the mixer to 80%, and the mixing time to 40 minutes;

[0047] (4) After mixing evenly, collect the product.

[0048] The content and form of sialic acid in the product obtained by the above scheme are very close to human milk, and meet the requirements of the national standard GB19644-2010.

Abstract

The invention discloses a dry process preparation method of sialic-acid-containing infant formula milk powder, which comprises the steps of peeling a raw material, adding high-fat milk powder, sialic acid and the like, uniformly mixing, and collecting the sialic-acid-containing infant formula milk powder. The dry process preparation method successfully solves the problem that the content of sialic acid in the infant formula milk powder is lower, so that the content of sialic acid is closer to a level of breast milk; the infant formula milk powder is normal in flavor and taste; and a technology is stable.

Description

technical field [0001] The invention relates to a dry method for preparing infant formula milk powder containing sialic acid, which belongs to the technical field of food engineering. Background technique [0002] Sialic acid (SA for short) is a kind of acidic nine-carbon monosaccharide, a kind of neuraminic acid derivative. Sialic acid mainly exists in four forms: free sialic acid, polysialic acid, derivatives of sialic acid and homologues of sialic acid. Sialic acid is widely distributed in a variety of organisms. As a component of complex sugars, it is embedded on the surface of all cells and the outermost ends of most vertebrate glycoproteins and glycolipid molecules. It is an important component of glycoproteins and glycolipids on the cell membrane. . The content of sialic acid in the nerve cell membrane is 20 times that of other cell membranes, and the content of sialic acid in the human brain is 2-4 times higher than that of other mammals. The main source of sialic...
