In order to avoid contamination and deterioration of milk powder, it should be avoided to be exposed to direct air after being opened, and it is not recommended to store it in the refrigerator. Because of the temperature difference and humidity difference inside and outside the refrigerator, it is easy to cause the milk powder to deliquesce, agglomerate and deteriorate. Milk powder after opening is generally stored in a dark, dry and cool place.
Pay attention to the tightness, it is best to choose a sealed container for storage, or clamp the milk powder bag to avoid ventilation and moisture. Every time after washing the milk powder, be sure to cover the lid tightly, so as to ensure that the milk powder is not easy to deteriorate.
Do not brew the milk powder for more than 2 hours. Sometimes the child is hungry, and the mother pours too much milk powder, or the baby doesn't have a good appetite one day, so the milk powder is bound to be inexhaustible. Maybe you will think about putting the milk powder aside and giving it to him when you are hungry next time.
If you really do this, then pay attention. It is best not to leave the prepared milk powder for more than 2 hours. Because of the temperature, the protein structure of the milk powder will be destroyed. If it is left for too long, the final nutritional value will be reduced, but it will not be good for your health. Therefore, it is best to drink the prepared milk powder in time, and it should be discarded after a long time.
Nutritional components in milk powder:
(1)Sn-2 palmitic acid is one of the saturated fatty acids that are abundant in breast milk. It accounts for about 25% of the total fat content and provides about 10% energy supply for infants. The appearance of Sn-2 palmitic acid solved the problem of low absorption rate of fatty acids and calcium in infant formula, and improved the absorption and utilization of energy, and improved the consistency of feces and the growth and development of bones.
(2) protein: supplying the body with nutrition.
(3) Fat: it supplies nutrients and energy to the body and provides milk with strong fragrance.
(4) Sugar: Milk contains lactose. Milk sugar is very important for children's development. It can promote the growth of beneficial bacteria in the human intestine, inhibit abnormal fermentation in the intestine, and be beneficial to intestinal health.
(5) Minerals: Minerals, also known as inorganic salts, are indispensable substances for the human body, including calcium, iron, phosphorus, zinc, copper, manganese, molybdenum, etc. These substances are commonly known as divalent minerals. Bivalent minerals are indispensable nutrients for human body, and these nutrients can not be directly produced in human body, but can only be obtained through food and water. In addition, trace elements such as calcium and zinc in divalent minerals are key nutrients in the growth of infants.
Science shows that casein peptide (CPP) can effectively promote the absorption of calcium, iron and zinc in bivalent minerals. In 20 12, this substance was added for the first time in Newbez's brand-new upgraded formula, which made outstanding contributions to the balanced nutrition absorption of infants.
(6) Vitamins: Milk contains all known vitamins, and its functions: Vitamin A promotes normal growth and reproduction and maintains epithelial tissue and vision; Vitamin B participates in the metabolism of sugar and energy in the body; Vitamin c against scurvy; Vitamin d can regulate the calcification ability of osteoblasts in various metabolic bone tissues; Vitamin e can resist oxidation and aging.
(7) Linoleic acid and linolenic acid: Babies who drink breast milk are smart and lively because they synthesize enough DHA/AA. If the baby's milk powder contains enough linoleic acid and linolenic acid, DHA and AA can be naturally synthesized in the body according to the baby's needs, so that the baby's brain can develop better.
If linoleic acid and linolenic acid can not be provided in sufficient proportion, it may be necessary to add DHA and AA, but adding DHA and AA is easy to oxidize, and the taste of formula milk will change after oxidation. Therefore, it is the key to add enough linoleic acid and linolenic acid to infant formula milk.
(8) Lactoferrin: Lactoferrin is the core immune protein in breast milk and an important non-heme iron-binding glycoprotein in milk. Adding lactoferrin to infant formula milk powder, which is also a unique nutrient component added by Yingnuo milk powder, can not only meet the needs of infant growth and development, but also improve infant immunity and protect infant health.
"Babies who breastfeed are less sick" is precisely the truth. Lactoferrin has been industrialized in some developed countries, such as New Zealand and Netherlands, especially in infant formula products, health food and fermented dairy products.
(9) Soybean lecithin: Soybean lecithin is a basic substance of life. It is not only an important component of human biofilm, but also a source of choline and fatty acids. It plays a key role in maintaining the physiological activity of biofilm and the normal metabolism of the body. Soybean lecithin is a component of cell membrane, which enhances the cell information transmission ability, improves the brain vitality, and enhances the self-repair ability of cell membrane to protect the liver and resist external invasion. This is a unique nutrient added to Yingnuo milk powder.
Lecithin is a nutritional product with comprehensive functions, which is often supplemented, and plays a very important role in preventing and improving cardiovascular and cerebrovascular diseases, strengthening the brain and improving intelligence, preventing fatty liver and cirrhosis, and beautifying the skin.
(10) Nucleotide: It is the basic component of all organisms and plays a dominant role in the growth, development, reproduction and inheritance of organisms. Maintain the normal function of baby's gastrointestinal tract and reduce diarrhea and constipation. Improve immunity and get sick less. Effectively reduce the baby's constipation.
