Is it better to drink fresh or pure milk? What s the difference?

Fresh milk and yogurt are not much different in terms of protein, fat and vitamins, and they can be substituted for each other. The differences between the two are:

The protein and fat of kefir are more easily absorbed by the body, and the utilization rate of calcium, phosphorus, iron, etc. is also greatly improved. The lactic acid bacteria in yogurt produce organic acids such as lactic acid, which effectively reduce the pH of the intestines, which can effectively inhibit the reproduction of harmful bacteria in the intestines. Yogurt increases the number of beneficial bacteria in the gut and maintains the balance of intestinal flora.

Yogurt can also promote the secretion of saliva and gastric juice, increase appetite, enhance gastrointestinal digestion, ** constipation, indigestion and other symptoms in adolescents.

However, yogurt cannot be heated and drunk, while milk can be heated and drunk, so it is more suitable for some people who are afraid of cold stomachs to drink fresh milk. Yogurt has a higher sugar content and is not suitable for fat people and people who are **. The baby's stomach and intestines are not well developed, and it is not suitable to drink yogurt, it is better to drink milk.

In addition, the acidic substances of yogurt are easy to corrode teeth, so you should pay more attention to rinsing your mouth after drinking.

Personally, I think that pure milk is more expensive than fresh milk in the first place, and the consistency is different in taste.

It's still pure milk.

Fresh milk is more nutritious than pure milk, but the nutrition of fresh milk will also be destroyed a lot after boiling, so it is better not to boil fresh milk. In particular, the "72 degrees Celsius, 15 seconds" process used in pasteurization produces fresh milk that causes less damage to nutrients. Therefore, fresh milk with a shelf life of 3 days is more nutritious than pure milk.

However, untreated fresh milk also contains some bacteria, which is also harmful to the human body.

Fresh milk, pure milk is not as good as homegrown milk.

From the point of view of freshness and nutrition, fresh milk is better than pure milk.

There is a difference between fresh milk and pure milk, but in fact, there is a difference in the nutrition of milk.

The processing raw materials of the two kinds of milk are the same, both are made of fresh milk, and the most essential difference between the two types of milk is the difference in sterilization methods. "Fresh milk, also known as pasteurized milk, is made of fresh milk as raw material, pasteurized fresh milk is raw milk that has been heated at a low temperature of 85, because the temperature of the sterilization method is not high, while killing harmful bacteria, it can maximize the preservation of nutrients and active substances in the milk.

Pure milk is room temperature milk, which is ultra-high temperature sterilized milk that has been processed by instantaneous high temperature sterilization, and this milk can be stored at room temperature. "The instantaneous temperature of UHT pure milk sterilization is at least 132, this sterilization method can kill all microorganisms in the milk, but the nutrients of the milk after sterilization are lost, especially calcium and vitamins.

Milk is indeed a good drink because it is very nutritious and has the reputation of "white blood". Milk is rich in high-quality protein, 100g of milk can provide about 3g of protein, the protein in milk is conducive to absorption, because the structure and proportion are close to the human body, the absorption rate is as high as 94%.

Fresh milk refers to pasteurized milk, pasteurization uses a sterilization temperature of 75-85 degrees Celsius, maintained for 30 minutes to 15 seconds (the higher the temperature, the shorter the time required), this sterilization method can kill most of the pathogenic bacteria, and protect as much as possible from the beneficial bacteria, vitamins and other heat-sensitive components in the milk. The most prominent thing in milk is its high-quality protein, the absorption rate of protein in milk is second only to the whole protein in eggs, the structure and proportion of its amino acids are closer to the human body, the absorption rate is as high as 94%, protein is a very important building component for the human body, tissue composition, muscle composition, enzymes, hormone synthesis, immune system elements, body carriers, etc., all revolve around protein, so it is said that drinking milk makes people strong.

Milk is the first bite of food after birth, it is a minimalist way to integrate protein, fat, water and other substances that are beneficial to the body, milk can promote human growth and development, as a mammal, human milk is naturally a particularly beneficial food for the body. The bagged fresh milk is not as good as the bottled fresh milk I order every day, but it will taste a little better than the boxed room temperature pure milk. Taste aside, bagged fresh milk has about the same nutritional profile as bottled fresh milk, with slightly lower protein and calcium.

Milk is one of the very good health drinks in life, and it is recommended to supplement the drink daily in the dietary pagoda of Chinese residents, and there is no world of difference in nutritional value between the two, because drinking milk is mainly for protein and mineral calcium. If possible, it is recommended to drink as much fresh milk as possible, and pure milk can be used for business trips or long-term storage.

The biggest difference between fresh milk and pure milk is that pure milk is extracted after processing, fresh milk is fresh milk, its nutrients will be more comprehensive, but it will easily cause lactose intolerance and allergies. If the hygienic conditions are handled well, the nutritional value of fresh milk is better.

Fresh milk is more nutritious.

1. The sterilization temperature is different. Fresh milk, also known as pasteurized milk, adopts continuous mild heating pasteurization method, and the sterilization temperature is low, generally 63 to 85 degrees Celsius, which can kill all pathogenic bacteria and ensure the safety of milk. Pure milk is instantaneously pasteurized at a temperature of 135 to 150 degrees Celsius to kill all microorganisms in the milk.

2. The shelf life is different. Fresh milk is always inseparable from the refrigerated storage environment of 0 to 10 degrees Celsius, that is, it must be stored in the refrigerator, and the shelf life is short, only 2 to 7 days; Pure milk has a long shelf life, up to 2 to 12 months at room temperature.

Due to the low sterilization temperature, fresh milk can retain the nutrients of milk relatively intact; Pure milk, on the other hand, loses more nutrients.

Therefore, fresh milk is more nutritious than pure milk.

Fresh milk has a shorter storage time than pure milk, and the taste is more positive than pure milk, so I personally feel that fresh milk is better, because fresh milk is very rich in nutrients.

Fresh milk has a shorter shelf life of 2 to 7 days, while pure milk has a longer shelf life, up to 2 to 12 months at room temperature. Due to the low sterilization temperature, fresh milk can retain the nutrients of milk relatively intact; Pure milk loses a lot of nutrients, so it is better to drink fresh milk every day.

The difference is that fresh milk is the milk produced by the factory's sterilization and reprocessing, while pure milk is squeezed directly from the cow, which will be more nutritious. Plain milk is better.

1. The sterilization method is different, pure milk is processed by the method of high temperature sterilization of 132, while fresh milk is processed by 85 low temperature heating, so it is also called pasteurized milk. 2. The shelf life is different, fresh milk can generally be stored for 5-7 days, while pure milk is treated by instantaneous high temperature heating, which will generally eliminate all the bacteria in the milk, so the shelf life is longer, and it can be stored for 1-3 months. 3. The storage location is different, due to the reason of the fresh milk sterilization method, in order to inhibit the reproduction of internal high-temperature strains, it can only be stored in a refrigerated way during the production, transportation and sales, and the temperature needs to be controlled below 10, while pure milk only needs to be stored in a place at room temperature and away from strong light.

Each has its advantages.

1. All are beneficial. Fresh milk and pure milk contain a large amount of protein, fat, minerals, lactose and other components, both of which have high nutritional value, moderate consumption can supplement a variety of nutrients needed for the human body, fresh milk and pure milk are mainly sterilized in different ways, it is recommended to choose according to personal needs.

2. The sterilization method is different. Fresh milk: Fresh milk is pasteurized, that is, low-temperature sterilization, which can not only kill germs, but also keep the nutrients and flavor contained in the milk unchanged, also called pasteurized milk.

Pure milk: Pure milk is sterilized by ultra-high temperature, the temperature of high temperature sterilization is extremely high, the instantaneous temperature can reach 130, although the temperature is very high, but the damage to the nutrients contained in the milk is small.

3. The shelf life is different. Fresh milk: Fresh milk still has some high-temperature resistant bacteria to survive, so the shelf life is short, generally in the refrigerator, can be stored for 5 7 days.

Pure milk: UHT sterilization destroys all the bacteria contained in the milk, so it has a long shelf life, and can be stored for 1 to 3 months at room temperature.

For all parents, after the baby is born, we must begin to pay attention to the baby's diet, generally to give the baby breast milk or milk powder, etc., as the baby grows up, you can give the baby to drink hail milk, which can supplement the baby with a variety of nutrients. There are two kinds of milk, pure milk and fresh milk, some friends can't tell the difference between pure milk and fresh milk, and think that it is the same milk, but in fact, there is still a difference between pure milk and fresh milk. The following will give you a detailed introduction to the difference between pure milk and fresh milk, which is better.

The differences between pure milk and fresh milk are as follows:

1. Different sterilization methods.

Pure milk, also known as UHT milk, is to sterilize fresh raw milk at UHT instantaneously to destroy some of the microorganisms and spores that can grow.

Fresh milk refers to pasteurized milk, which means that raw milk or raw milk is heated to a suitable temperature to kill some harmful bacteria in the milk.

2. The shelf life and storage methods are different.

Pure milk can reach the "sterile" level because it is UHT sterilized and can be stored at room temperature for 1 to 6 months.

Fresh milk has a low sterilization temperature, and most of the shelf life is 7-10 days, and it is refrigerated at 2-6 degrees.

3. The nutritional value is different.

Because pure milk is processed at ultra-high temperature, some heat-resistant nutrients such as vitamins may be destroyed, but the degree of damage is very low, and the nutritional value is still relatively high.

The low sterilization temperature of fresh milk can preserve the active nutrients in the milk to the greatest extent.

4. The suspicion is different.

As long as pure milk is stored at room temperature and protected from light, the transportation cost is low, and the transportation cost is relatively low.

Fresh milk needs to be transported in the whole cold chain, and the cost is high, so it is more expensive than ordinary pure milk.

To sum up, pure milk and fresh milk are better than fresh milk, and both have relatively high nutritional value, so you can choose according to your own needs.
