How to distinguish the quality of Milk powder from color?

Posted on: November 12, 2019, by Samantha

Introduction: Yesterday, I received a very urgent consultation. A mother said that the color of the milk powder bought this time is different from what she had brought before. The milk powder brought this time is whiter than the milk powder brought last time. She suspects that the milk powder bought from the milk market this time is fake, and she dares not give it to her children and wants to find a substitution for milk.

After replying to the mother's consultation, the author also searched the relevant information on the Internet, finding that many mothers are consulting similar questions, such as: "Why is the color of this can of milk powder yellow than that of the previous can?" why the brewed milk color not as same as the milk powder’s color? " "What are some black particles in milk powder?"... If your baby is also eating milk powder, you have encountered the same situation, then today I will show you the reasons for these differences in milk powder.

Why is the color of milk powder different?
Generally, the color of infant formula milk powder is uniform Milky yellow.  According to the physiological characteristics and different milk nutrients requirements of infants at different stages, the content and proportion of protein, fat, carbohydrate, vitamins, and minerals in infant formula milk powder at different stages are adjusted. Because of the differences in the formula of milk powder of different brands, there may be some differences in color, such as creamy yellow, light yellow, or even white, but as long as the powder is lustrous, the color is uniform and odorless, it belongs to the normal character.

In addition to the differences in the formula, the color of milk powder may also be affected by the milk source, that is, we often say that different seasons of milk source and different places of milk source, the color of milk powder produced will be slightly different. At the same time, the content of fat in milk powder recipes will also affect the color of milk powder. Generally, the color of whole milk powder is yellow, and skimmed milk powder is white. In addition, different brands of milk powder have different technology, which may also cause differences in the color of milk powder.

Therefore, it is not comprehensive to distinguish the quality of milk powder only by observing the slight differences in color.

Although normally, the color of milk powder varies slightly if the color of milk powder you buy is the following, you should pay attention to it:
1. Milk powder is dull and glossy;
2. Turquoise, brown and grey;
3. The color becomes darker after opening.
4. There are hard blocks when the color changes.
5. The color of milk powder is not uniform.

What are the red particles in milk powder?
1. The Supplementary  (trace elements and vitamins) which added to milk powder, such as vitamin B12, lactoferrin, beta-carotene, may produce pink particles, but the probability of this phenomenon is low,  if the red particles in milk powder (except foreign bodies), which is a normal phenomenon, need not worry too much.
2. If the product is stored at high temperature for a long time, the browning of milk powder will be aggravated and the color will be darker, showing brown or dark red. If there are a lot of red particles in the milk powder, it is possible that the milk powder has deteriorated, so it is recommended not to eat anymore.

What are the black particles in milk powder?
Among other foreign bodies, this is likely to be the "lactose caramel" in milk powder. Lactose is a kind of carbohydrate with a low cooking temperature of about 130 Celsius degree. Spray drying is carried out at a temperature of 130 Celsius degree to 160 Celsius degree, so in the production process, a small amount of lactose will be converted into black or brown Caramel granules after spray drying. Although the milk factory will use multi-channel screen technology to filter out some larger particles, occasionally small particles will remain.

What should we pay attention to in the process of baby milk powder feeding?
1. When the baby is full or does not want to eat anymore, the baby's signs should be respected and the baby should not be forced to eat.
2. Don't let the baby sleep with a bottle, because the carbohydrates in the milk will corrode the baby's teeth and easily cause tooth decay.
3. Pay attention to the size of the opening of the pacifier and the strength of the baby when sucking, so as not to cause excessive air inhalation.
4. Develop good feeding habits at fixed intervals and fixed times per meal.
