How does milk come about? Is cow s milk milk

Yogurt: try not to drink, there is no standard protein content, the quality level is not high, fermented products, try not to drink.

Pure milk: Yes, don't for 45-50 pieces of milk. 250ml, 12 bottles.

Don't buy sixty or seventy for more, the multiplication will be calculated by yourself. This point is the same as what amino acids are in soy sauce, to buy soy sauce, you can buy it for just a few dollars, and there is no need to buy seven or eight yuan for a dozen yuan.

Containing all kinds of bacteria: don't buy it, stomach acid is a strong acid, and it has long been extinct in the stomach.

When buying milk, it depends on the formula, and the formula has nothing else but raw milk.

Milk, like human milk, is a nutrient synthesized by the cow itself after calving, and it was originally used to feed the calf, and the excess was collected by people.

It is the processing of people who are squeezed out of the cows.

Extruded from cows.

Milk is one of the oldest natural beverages and is known as the "white blood", and as the name suggests, milk is squeezed from female cows.

In different countries, there are different grades of milk. At present, the most common are whole-fat, low-fat and skim milk. At present, there are quite a lot of additives in milk on the market, such as high-calcium and low-fat milk, which adds calcium.

Milk is rich in minerals, calcium, phosphorus, iron, zinc, copper, manganese, molybdenum. The most rare thing is that milk is the best calcium in the human body**, and the ratio of calcium and phosphorus is very appropriate, which is conducive to the absorption of calcium. There are at least 100 kinds of types, and the main ingredients are water, fat, phospholipids, proteins, lactose, inorganic salts, etc.

Of course not, milk is a very tasty, very nutritious thing, milk is also very delicious, the nutritional value is also very high, in fact, there is a difference between milk and milk.

Although cow's milk and cow's milk are both milk produced by dairy cows, their nutritional value is different. In terms of nutrition, there are more than 3,000 nutrients in bovine colostrum, including more than 200 macro components, including all the nutrients required for human development. In other aspects, bovine colostrum contains 10 times more insulin-like growth factor than ordinary milk, and the content of VA, VE, VD3 and carotene in colostrum fat is more than 20 times higher than that of whole milk, and the content of iron and copper is 5 6 times and 3 4 times higher respectively.

Therefore, it is entirely possible to say that bovine colostrum is more nutritious than cow's milk.

Difference Between Cow's Milk and Cow's Milk:

1. The difference between cow's milk and cow's milk is that bovine colostrum is rich in active immune substances, while cow's milk does not. The composition of milk is closer to breast milk, and immunoglobulin is 50 times that of breast milk, so it can increase the physical fitness of the human body, improve immunity, reduce the chance of cold, bronchitis and viral infection, and prevent the occurrence of various diseases such as viral disease, viral hepatitis, viral pediatric diarrhea, etc. At the same time, bovine colostrum contains unique growth factors, which can significantly promote the growth and development of children.

2. Milk and cow's milk, from the time of time is only the product of different stages of milk secretion, milk, that is, cow's milk, which is rich in protein and fat and various nutrients required for the growth of young children, is recognized as a nutritious food, and it is very similar to bovine colostrum is an emerging natural food that is both nutritious and can enhance children's immunity.

Cow's milk and cow's milk are not the same food, but there are differences.

Extruded from the cow, usually after human processing.

Each 100 grams of milk contains 87 grams of water, protein grams, fat 4 grams, carbohydrates 5 grams, calcium 120 mg, phosphorus 93 mg, iron milligrams, vitamin A140 IU, vitamin B mg, vitamin mg, niacin mg, vitamin C 1 mg, available calories 69 kcal.

Types of Milk:

1. Pasteurized milk, which is sterilized by pasteurization, needs to be refrigerated at 4 to 10 degrees throughout the process, which is currently more popular;

2. Normal temperature milk, using ultra-high temperature sterilization method, can kill all the harmful bacteria of stupid mu, and the shelf life is extended to 6 12 months, without refrigeration;

3. Reduced milk, milk powder shall not be used for pasteurized milk, but room temperature milk, yogurt and other dairy products can be used to newly squeeze milk containing lysozyme and other antibacterial active substances, which can be stored under 4 for 24 hours to 36 hours;

4. The sterilized milk generally has a strong taste;

5. Antibiotic-free milk refers to milk produced from raw materials that do not contain antibiotics.

What does whole milk mean? In fact, whole milk is milk that retains all the nutrients of milk. It contains a lot of fat-soluble vitamins and is very nutritious and comprehensive, and tastes better. It is suitable for consumers of all ages, especially for young and middle-aged people.

1. From the perspective of calcium supplementation, whole milk, that is, our common ordinary milk, has a protein content of about 3%, a fat content of about 3%, a calcium content of about 120 mg 100 ml, and contains fat-soluble vitamin K, vitamin A, vitamin E, etc., which is one of the best foods for us to supplement calcium.

2. Whole milk is the closest food to perfection, and the calcium contained in it is one of the best sources of calcium for the human body; Moreover, it has the original nutrients that no artificial nutrition can match.

3. The protein in whole milk is mainly casein, white scab protein, globulin, milk protein, etc., containing more than 20 macroliters of amino acids in 8 kinds of amino acids necessary for the human body, milk protein is a full-valent protein, and its digestibility is as high as 98%.

4. Milk fat is high-quality fat, the best quality, its digestibility is more than 95%, and it contains a lot of fat-soluble vitamins. The lactose in whole milk is galactose and lactose, which are the easiest sugars to digest and absorb. The minerals and trace elements in milk are dissolved, and the content ratio of various minerals, especially calcium and phosphorus, is more appropriate, which is easy to digest and absorb.

Cow's milk is one of the oldest natural beverages milked from female cows, known as white blood. [1] Milk is a uniform fluid, with the inherent flavor of milk, a sweet and mellow taste, and has the effects of supplementing protein, calcium, calming and calming the nerves. [2] Look at the ingredients raw materials.

Efficacy. Core efficacy.

Sleep, calcium, beauty and beauty.

Sexual taste is flat and sweet.

Suitable for: Patients with calcium deficiency.

Not suitable for people with digestive tract diseases, milk allergies, lactose intolerance.

Contraindications: Lactose intolerance, digestive tract diseases, milk allergy.

Milk is one of the favorite foods in people's daily life, which is nutritious, easy to digest and absorb, and is the most ideal natural food. Milk is rich in calcium, vitamin D, etc., including amino acids required for human growth and development, and the digestibility can be as high as 98, which has the effects of sleep, calcium supplementation, beauty and beauty.

1. Sleep well. The tryptophan in milk can be converted into serotonin and melatonin, which affect mood and sleep, which can calm the nerves and help you fall asleep.

2. Calcium supplementation. Milk is the best calcium for the human body**, so drinking milk can effectively supplement calcium.

3. Beauty and beauty.

The whey in milk has an anti-wrinkle effect on the face and keeps it smooth and moisturized.

Nutritive value. Milk is a complete protein food, of which 40% is casein, followed by whey protein. The latter has a sulfur content equivalent to egg white.

In addition, it also contains vitamin B1, vitamin B2, vitamin B6, vitamin C, vitamin P, pantothenic acid, etc. Milk is rich in vitamin A, which can prevent dryness and dullness, make it fair and shiny, and milk can provide sealing oil for the milk to prevent water evaporation, and can also temporarily provide water to ensure smooth and moisturized. The calcium in milk is the easiest to be absorbed, and the combination of phosphorus, potassium, magnesium and other minerals is also very reasonable, pregnant women should drink more milk, and middle-aged women around menopause often drink milk to slow down bone loss.

Cows eat grass, which breaks down the protein in the grass into amino acids, which are recombined into milk protein in the body, and then secreted from the mammary glands along with water, antibodies and some other nutrients, and milk is produced.

1. Nutritional characteristics of milk:

Milk and its products are one of the important dietary proteins, calcium, phosphorus, vitamin A, vitamin D and vitamin B2.

Fresh milk is mainly a complex latex composed of water, fat, protein, lactose, minerals, vitamins, etc., in which the water content accounts for 86% to 90%, so its nutrient content is relatively low compared with other foods. The specific gravity of milk is on average, and the specific gravity is related to the solid content of the milk. Except for the relatively large change in fat content, the other components of milk are basically stable, so the specific gravity can be used as a simple index to evaluate the quality of fresh milk.

1) Protein:

The protein content in milk is mainly composed of casein, whey (white) protein and lactoglobulin, and a small amount of other proteins, such as immunoglobulins and enzymes. Where 20 percent of the precipitated milk protein is called casein.

Casein is a heat-stable protein that can precipitate under acidic conditions, and yogurt and cheese are made on this principle. In milk, casein combines with calcium and phosphorus to form casein particles, which exist in milk as a colloidal suspension. Whey protein is unstable to heat and coagulates and precipitates when heated.

The digestion and absorption rate of milk protein is 87% 89%, and the biological value is 85%, which is a high-quality protein.

2) Fat: Milk fat is about to be dispersed in the emulsion with micro-granular fat globules, which is in a good emulsified state, easy to digest and absorb, and the absorption rate is as high as 97%. The lipids in milk are mainly triglycerides, a small amount of phospholipids and cholesterol, the fatty acid composition in milk fat is complex, oleic acid accounts for 30%, linoleic acid and linolenic acid account for the sum respectively, and the content of short-chain fatty acids (such as butyric acid, hexanic acid, caprylic acid) is high, about 9%, which is the reason why milk fat has a good flavor and is easy to digest.

3) Carbohydrates:

Milk carbohydrates are mainly lactose, and the lactose content of bovine is about. Lactose in the intestine can promote the absorption of calcium, iron, zinc and other minerals, and improve their bioavailability; Promote the reproduction of intestinal lactic acid bacteria, especially bifidobacteria, improve the balance of human microecology, and promote the synthesis of B vitamins by intestinal bacteria.

Some people do not drink milk for many years after adulthood, and the lactase activity in the body is very low, and they cannot decompose lactose, and lactose is decomposed and fermented by the intestinal microorganisms in the intestines, resulting in symptoms such as flatulence and diarrhea, which is called lactose intolerance. This group of people can consume lactase-treated milk powder or drink yogurt.

The formation process of milk is that cows eat edible grass, decompose the envy of the protein in the grass into amino acids, recombine it into milk protein in the body, and then secrete it from the mammary glands together with water, antibodies and some other nutrients, that is, milk.

Milk is one of the oldest natural beverages and is known as white blood. Milk is rich in nutrients such as protein, fat, vitamins and minerals, milk protein contains essential amino acids for the human body, and milk contains almost all kinds of vitamins required by the human body.
