Pure milk is white while some milk powder is yellowish, is it because of added coloring?
The normal color of milk powder is a uniform milky white or creamy white. The reasons for the different colors of the same brand of milk powder are as follows. Raw milk)The grass and other foods that cows eat vary slightly from season to season. Raw materials) The amount of raw materials added to raw milk has a certain normal up and down fluctuation (generally the national regulations fluctuation range within 20%, and Wundasan regulations within 10%), causing differences in color. Temperature: The control of temperature in the drying process has a great influence on the color of milk powder, the higher the temperature, the darker the color of milk powder. Particle size: relatively large particles, the color is relatively slightly yellow, creamy yellow; relatively small particles, the color is relatively light, creamy white. The usual color of milk powder is milky white or creamy white. According to the above reasons, there may be some differences in the color of the same variety of milk powder, but it has no effect on the quality.
The color of infant formula is overall a uniform milky white, and there are almost no truly pure white formulas. The size of the color difference between the milk powder determines the visual perception, and the closer it is to light yellow the easier it is to judge it as white. As soon as you see the color of the powdered milk, you will see a creamy white, pale yellow, or even whitish color. If the powder is glossy, uniform in color and no odor, it is the normal traits.
Preparing milk powder at high temperatures will cause the denaturation of milk powder protein precipitation, etc., poor speed solubility, hanging wall, may cause white spots on the bottom of the bottle; preparing milk powder at too low a temperature, speed solubility is easy to become poor. Secondly, water hardness may cause changes in the solubility of milk powder. Milk powder contains lipid formula, how much wall hanging is normal. Some products can improve the quick-solubility of milk powder by adding dissolving aids, and the quick-solubility looks especially good. Although there are no insoluble substances on the walls or at the bottom of the bottle, the addition of accelerated solvents is not a beneficial substance for the baby. Solutions pay attention to the cleaning temperature of the milk powder and the correct cleaning method, prolong the shaking time, so as not to bottle cleaning when the amount of water is full, to ensure that a certain amount of space.
