Whey calcium (milk calcium; Whey inorganic salt concentrate), milk calcium is whey inorganic salt concentrate, which is a kind of inorganic salt source with good nutritional value and easy digestion and absorption. The total inorganic salt content in milk is about 0.7%, and the calcium content is about 0. 1%.

Compared with calcium in other foods, whey calcium is a high-quality calcium source, because about 70% of calcium in milk exists in casein micelle state, of which about 40% is colloidal calcium phosphate and about 30% is calcium bound to casein. About 30% of calcium in milk is soluble calcium, about 30% of soluble calcium is ionized calcium, 60% is calcium citrate, and the remaining 10% is calcium phosphate.

Basic introduction Chinese name: whey calcium alias: milk calcium; Characteristics of whey inorganic salt concentrate: digestible absorption content: milk 0.7%, milk calcium, calcium supplement, precautions, goat milk calcium, vitamin D calcium, physiological function, interference factors, promotion factors, α -linolenic acid, milk calcium deficiency, product safety, milk calcium is a pure natural active high milk protein calcium extracted directly from milk. Milk minerals rich in milk calcium are natural sources extracted from milk. The advantages of these ingredients not only provide balanced nutrients, but also promote the absorption and utilization of calcium, such as phosphorus, magnesium, lactose and protein. The scientific ratio of calcium and phosphorus in milk calcium is 2: 1, which is beneficial to human absorption and utilization. Because milk is rich in lactose and protein, its absorption rate is much higher than other common calcium. The absorption rate of milk calcium is as high as 62% ~ 70%, which is 2.5 times that of calcium carbonate and calcium gluconate, 1.75 times that of calcium lactate and 5.5 times that of shellfish calcium. Eating milk calcium will not lead to flatulence, edema and constipation, so milk calcium is a good source of calcium supplementation for infants at present. Milk calcium, also called whey calcium, is a combination of calcium extracted from milk, which is obtained after dehydration, degreasing, drying and spraying. Its ingredients include calcium citrate, calcium phosphate and ionized calcium, and it is also rich in nutrients such as zinc, phosphorus, protein, immunoglobulin, growth factor and lactoferrin. For infants and pregnant women with very fragile gastrointestinal function, milk calcium is less than other mineral elements. Among all calcium, milk calcium is easily absorbed by human body; The calcium-phosphorus ratio of milk calcium powder is reasonable, and natural nutrients such as vitamin D and casein phosphopeptide (CPP) are good factors to help calcium absorption. Milk calcium can be separated out in the human body without too much gastric acid, and then it can be directly absorbed and utilized by the human body, which can quickly adjust the blood calcium balance and enhance physical fitness. Milk calcium is recognized as a food-grade calcium supplement with high bioavailability among known calcium, because there is a proper amount of protein and a reasonable calcium-phosphorus ratio of 21; At the same time, because there are no chemical components and processes in the production process, there is no burden on the gastrointestinal tract. Therefore, milk calcium is a more suitable source of calcium supplement for infants, pregnant lactating mothers, children and the elderly. Most people confuse milk calcium with calcium lactate, but in fact they belong to different concepts. Milk calcium is a mixture made by physical purification of natural milk, and its main components are calcium citrate and tricalcium phosphate. Calcium lactate is a pure substance composed of two molecules of lactic acid and one molecule of calcium ion. The reference intake of calcium in milk is 200 1 dietary calcium reference intake of China residents revised by China Nutrition Society: age daily reference intake (mg) 0-6 months 300 1 year -4 years old 400 4 -7 years old 600 7 years old-1year 800/kloc-. 8 years old 1000 18 years old -50 years old 800 50 years old-1000 pregnant women in the second trimester 1000 pregnant women in the third trimester 1200 wet nurse 1200 calcium supplement function 1. Timely calcium supplementation is a simple and effective method. The secret is that after the child falls asleep, the endocrine system is the most active and releases the most growth hormone. Growth hormone is the catalyst for children's growth. At this time, a large amount of calcium is added to accelerate the calcification and maturity of new bones, which can be described as "perfect combination" and the child will grow taller. 2, calcium-weight loss scientists believe that after the increase of human blood calcium, it can increase the secretion of a hormone called calcitonin, calcitonin can reduce people's appetite. Adequate calcium can combine with fatty acids and cholesterol in food in the intestine, blocking the absorption of fat in the intestine and making it excreted. This method is especially suitable for children to lose weight, that is, to supplement calcium and reduce fat, which can be described as killing two birds with one stone. 3, calcium supplementation-skin care Many people insist on calcium supplementation for a long time, the first thing that shows is ruddy and shiny. The reasons are as follows: first, because blood vessels have the characteristics of hypocalcemia spasm, when calcium is deficient, skin vascular spasm causes insufficient blood supply to the skin. Secondly, calcium can promote the formation of subcutaneous elastic tissue, make the skin elastic, and thus produce wrinkles in children. At the same time, it can also inhibit the appearance of senile plaques. It can also maintain the normal luster of hair. 4, calcium supplementation-prevention of myopia I wonder if you know that myopia, an eye disease that harms young people's vision, will also be "candidly admit defeat" in front of calcium. Ophthalmologists tell us that if the eyeball lacks calcium, the intraocular pressure will not be maintained normally, just as high and low pressure will make the light bulb flash, which will lead to myopia. Therefore, in the high incidence age of myopia-adolescence (specifically, the years from the age of eleven or twelve to seventeen or eighteen), supplementing enough calcium is likely to exclude myopia in vitro. 5. Calcium supplementation-prevention of premenstrual syndrome in women According to the latest article published in the American Journal of Obstetrics and Gynecology, premenstrual symptoms (emotional impetuousness, depression, lower abdominal pain and swelling pain) can be reduced by 50% only by supplementing enough calcium. This study targeted 720 women with PMS aged 65,438+08-48. Experts believe that premenstrual symptoms have a lot to do with long-term calcium deficiency. If calcium can be supplemented, especially the high-quality milk calcium with good absorption and high effective utilization rate, it can regulate the secretion of some hormones, thus alleviating premenstrual symptoms and playing the role of overall fitness. The key point of calcium supplement is absorption, in which milk calcium is 80%, calcium carbonate is 40%, calcium lactate is 32%, calcium acetate is 29%, calcium citrate is 2 1%, calcium hydrogen phosphate 15%, calcium gluconate is 9% ... In the comparison of calcium absorption rate of various elements, the absorption rate of milk calcium with good performance is as high as 80%. Note: Look at the product information. Mothers should contact the first window of the product when choosing milk calcium. When choosing, they must read the product information carefully, pay attention to the protective performance of the packaging to the product, and choose a safe, suitable and reliable product for the baby. In packaging information, special attention should be paid to the identification of "food name, ingredient list and nutritional components". Because this information can reflect the source of the product and what ingredients it contains. Look at the ingredients. The raw material of milk calcium should be extracted from natural milk. Natural calcium source has the characteristics of high calcium content, easy digestion and absorption by human body, safety and no side effects, which can well meet the needs of rapid growth and development of baby bones. Solubility and dissolution are prerequisites for absorption. In water at 25℃, the calcium ion concentration of saturated solutions of different calcium agents is (mg/100 ml). L- calcium lactate1345; Calcium chloride1300; Racemic calcium lactate 702.8; Calcium gluconate 370; Amino acid calcium 224; Calcium hydroxide 65; Calcium citrate 20; Calcium carbonate 0.56. In order to improve the solubility, many factories grind insoluble calcium (such as calcium carbonate) into ultrafine powder in advance and then bond it. After taking it, the drug quickly disintegrates and can react with gastric acid to generate soluble calcium chloride, thus overcoming the problem of low solubility. It is also worthy of mothers' attention to see the protective characteristics and functions of packaging on milk calcium nutrition. Good packaging generally adopts light-tight aluminum film packaging, which can effectively prevent the product from being oxidized by light. Secondly, the aluminum film has strong sealing performance, which can prevent the product from being affected with moisture. Thirdly, the moisture-proof bag is packed with aluminum-plastic plastic blister board, which can not only make the product independent, but also facilitate the use according to the quantity; But also avoids the mutual adhesion between products, and better protects the integrity of the nutritional components of the products. Some products on the market are packed in whole bottles. If it is not stored correctly after opening, the whole bottle will easily get wet and cause unnecessary waste. Look at the origin. Many products are processed and packaged on behalf of others. If it is impossible to judge whether the manufacturer is a direct seller or an agent, it is more important to look at the place of origin. Look at the brand Most people will choose the brand of Sinopharm when choosing medicine, so you need to look at the brand when choosing milk calcium. If you can't judge, you can go to official website to inquire or consult the merchants who need to buy. I believe you can also get some information in communication. Making exquisite, quality-conscious, complete and accurate packaging can reflect the manufacturer's attention to product quality and details, and better reflect the manufacturer's sense of responsibility to society and consumers. Products related to the health of infants and young children have higher requirements, so when choosing milk calcium for babies, we should not only appreciate the beauty of the packaging, but also pay attention to the packaging information and product protection function, especially the packaging of milk calcium products, and the preservation of milk calcium nutrients is very important. Goat milk calcium vitamin D calcium goat milk vitamin D calcium is a natural milk calcium tablet developed for children and adolescents, which is extracted from the whey of healthy goat milk. The characteristics of goat milk calcium are 1, and the ratio of calcium to phosphorus is good. The calcium-phosphorus ratio of goat milk vitamin D calcium tablets is 1.8: 1, which is closer to breast milk and has better calcium absorption without hurting the stomach. 2. Fat particles are very small. The fat globules and protein granules of goat's milk are only 1/3 of that of milk, with uniform particle size, which is easier to be digested and absorbed by human body. Protein has the same structure as breast milk. Goat milk contains a lot of whey protein, but does not contain foreign proteins that can cause allergies in milk. Therefore, goat milk is easier to digest and absorb than other dairy products, and will not cause allergic symptoms of dairy products such as stomach discomfort and diarrhea. It is a dairy product acceptable to people of any physique. 4. The content of unsaturated fatty acids is high. In the fat structure of goat milk, the carbon chain is short, the unsaturated fatty acid content is high, and it is in a good emulsified state, which is more conducive to the direct use of the body. 5, especially suitable for people with allergies and physical weakness. Casein structure of goat milk is different from that of milk. Goat milk mainly contains α-2S casein and β-casein, which is easily decomposed by yeast. While milk mainly contains α- 1S casein. Therefore, people who are allergic to milk and have a weak constitution can completely accept goat milk. 6, high nutritional value. Goat milk contains more than 200 kinds of nutrients, rich in minerals, trace elements, vitamins, taurine, docosahexaenoic acid and so on. Similar to breast milk. The total content of protein, minerals and vitamins is higher than that of milk. 7. Rich in bioactive factors. Goat milk contains bioactive factors "cAMP", "ATP" and "EGF" growth factors, which have various regulatory functions in the body. "cAMP" is an anti-cancer factor recognized by the scientific community, which can maintain the metabolic balance of human body, increase the content of serum protein and albumin, and increase the disease resistance of human body. It can improve myocardial nutrition and soften blood vessels, and is very effective in improving the prevention and treatment of arteriosclerosis and hypertension. 8. Don't get angry easily. The common "excessive internal heat" of infants and young children is mostly due to poor immune function and imperfect endocrine and metabolic function. Generally, aphtha, constipation, local swelling and pain are classified as "getting angry". This is basically consistent with the inflammatory reaction in modern medicine. "Compendium of Materia Medica" and "For Urgent Use" both record that goat milk can cure aphtha, head sore, constipation and so on. 9. The cost is high. Dairy goats are animals that feed on whole grass (including roots), so their breeding will be limited, and the milk source of goat milk is very scarce. In addition, the milk production period of dairy goats is short, and March-10 is the milk production period of dairy goats every year, so the milk production cannot be compared with milk. These factors will inevitably lead to goat milk being more expensive than milk. In some developed countries, goat milk products are high-end products in the dairy market, and consumers are mainly high-income families. Physiologically, calcium in bones and teeth is continuously released under the action of osteoclasts and enters the mixed calcium pool. On the other hand, the calcium in the mixed calcium pool is constantly deposited in osteoblasts, which makes the bones constantly renew. Children's bones are renewed every 1-2 years, and the renewal speed becomes slower with age. Maintaining neuromuscular activities includes neuromuscular excitation, nerve impulse conduction and normal heartbeat. Calcium supplementation can reduce the incidence of pregnancy-induced hypertension. Promote the activity of enzymes, such as adenosine triphosphatase, lipase and protein decomposition enzyme. Calcium also participates in the blood coagulation process to maintain the acid-base balance of body fluids and cell proliferation. 1 Effects of oxalate and phytate in diet They can combine with calcium to form salts that are difficult to absorb, such as calcium phytate and calcium oxalate, thus reducing the absorption rate of calcium. Dietary fiber dietary fiber interferes with calcium absorption, which may be due to the combination of aldonic acid residues with calcium, resulting in fat indigestion, especially excessive fat. It can make unabsorbed fatty acids and calcium form calcium soap, and insoluble calcium soap is discharged from feces, so that calcium is lost. When vitamin D is insufficient, the calcium binding protein necessary for calcium absorption decreases. Therefore, when ultraviolet rays are insufficient or blocked in north latitude or fog, more attention should be paid to vitamin D. The long-term calcium-phosphorus ratio is not suitable for China's diet. The ratio of calcium to phosphorus is 1: 1.5, and long-term intake of too much phosphorus will affect the absorption rate of calcium. The ideal ratio in infancy is 1.5: 1, and in adulthood it is 1: 1. Taking acidic preparations can also interfere with the absorption of calcium. Vitamin D can induce the synthesis of a calcium-binding protein in vivo, which is beneficial to calcium transport through intestinal wall and enhance calcium absorption. Lactose lactose can chelate with calcium to form a low molecular weight soluble complex, which is decomposed and fermented by intestinal bacteria in the intestine to produce acid, reducing the PH value of intestinal cavity. Conducive to the absorption of calcium. The creative combination of calcium agent and perilla oil not only provides a synthetic scheme of calcium supplement and nutritional supplement for infants, pregnant women and parturients, but also solves the problem of poor calcium supplement effect for artificially fed and weaned infants. Protein natural calcium source, calcium purity is much higher than other calcium sources, and provides protein. The suitable ratio of calcium to phosphorus is a completely natural source of milk calcium, and the ratio of calcium to phosphorus is 1.8: 1, which is the same as that of human bones and is easier to absorb. Milk is primitive, natural and pure. It has no effect on the baby's stomach and contains no pigment. Casein calcium peptide Casein calcium peptide (P) is an efficient calcium accelerator. Calcium in food becomes soluble calcium under the action of gastric juice (hydrochloric acid), but it enters the small intestine in neutral to weakly alkaline environment, and some of it will combine with phosphoric acid to form insoluble calcium phosphate precipitate, which cannot be absorbed by human body. The existence of casein calcium peptide will prevent the precipitation of calcium phosphate and keep calcium ions dissolved, thus improving the calcium absorption rate. Fructooligosaccharides, GOS and other prebiotics, namely fructooligosaccharides, are a kind of water-soluble dietary fiber. Fructooligosaccharides are fermented by bacteria in the large intestine to produce L- lactic acid, which can dissolve minerals such as calcium, magnesium and iron and promote the absorption of minerals by human body. GOS (galactooligosaccharide) is a functional oligosaccharide with natural properties, which can effectively promote and improve the value-added and balance of beneficial bacteria such as Bifidobacterium in human body, improve the absorption rate of trace elements such as calcium and phosphorus, and improve the intelligence of infants with α -linolenic acid.

Experts pointed out that foreigners have no adverse reactions after eating some new resource foods, but the physical condition of China people is different from that of foreigners, and the organs and resistance of babies are not as good as that of adults. For the sake of safety, it is forbidden to add milk mineral salt to infant food. The reason why milk mineral salt can't be added to infant food, especially infant cheese, is that milk mineral salt is added to general food to increase the calcium content, and the calcium content of cheese itself is already quite high, which is six to seven times that of ordinary milk. "Infants' kidneys are not mature enough to absorb foods with high protein and calcium. If eaten, it will cause an excessive burden on the kidneys and affect healthy development.
