The invention discloses a milk beverage stabilizing agent, an acid milk beverage using the same and a preparation method in the technical field of food. The milk beverage stabilizing agent comprises the following components in percentage by
mass: 50%-70% of carboxymethyl
curdlan, 10%-30% of Arabic gum, 10%-20% of
propylene glycol alginate and 5%-10% of
guar gum. The acid milk beverage comprises the following components in percentage by
mass: 1%-8% of
whole milk powder or defatted milk
powder, 0.2%-1% of stabilizing agent, 10%-20% of white granulated
sugar and the balance of water. The preparation method for the acid milk beverage comprises the following steps: taking 35 to 55 DEG C water, adding the white granulated
sugar and the stabilizing agent into the water in turn, and stirring the mixture till the white granulated
sugar and the stabilizing agent are dissolved to obtain solution A; taking the 35 to 55 DEG C water, adding the
whole milk powder or the defatted milk powder into the water, and stirring the mixture till the
whole milk powder or the defatted milk powder is dissolved to obtain solution B; and mixing the solution A and the solution B, cooling the solution to between 15 and 25 DEG C, adjusting pH to 4 by using
citric acid solution, and heating, homogenizing and pasteurizing the solution to obtain the acid milk beverage. Because the carboxymethyl
curdlan and the Arabic gum are introduced into the stabilizing agent, the stabilizing agent has good emulsifying effect and
acid resistance, and can effectively improve the stability of a product.
