The difference between pure milk and fresh milk, the difference between fresh milk and pure milk

Pure milk. And.

Fresh milk. The difference:

First, the sterilization method is different:

The difference between fresh milk and pure milk is actually the nutrition of milk.

There is still a difference. The processing materials of both types of milk are the same, and they are both fresh.

Milk is the raw material, and the most essential difference between the two types of milk is the sterilization method.

Same. Fresh milk: also called.

Pasteurized milk.

It is made of fresh milk, pasteurized fresh milk is raw milk that has been heated at a low temperature of 85 degrees.

Pure Milk: Belongs.

Milk at room temperature. It is instantaneously autoclaved.

UHT milk.

This milk can be stored at room temperature, and UHT pure milk is sterilized at an instantaneous temperature of at least 132, and this sterilization method kills all microorganisms in the milk.

Second, the nutritional value is different:

Fresh milk: due to the low temperature of the sterilization method, it is killed.

Harmful bacteria. At the same time, it can maximize the preservation of nutrients and active substances in milk. No stabilizers are added

Thickeners. Emulsifiers.

Wait. Pure milk: After high temperature sterilization, milk loses a large amount of nutrients, especially calcium and vitamins.

Figuratively. Let's take an analogy.

Pasteurized milk. Be just like.

Fresh fruit. Whereas.

UHT milk.

Be just like. Canned fruit.

From the point of view of freshness and nutrition, fresh milk is preferred.

Yu Chun. Milk.

Third, the storage location is different:

Fresh milk: Fresh milk after collection and.

The sales process. , it needs to be cooled below 10 to inhibit the proliferation of bacteria during this time. Therefore, in the whole process of production, transportation and sales, it is necessary to maintain a certain temperature and refrigerate storage.

Pure milk: only need to be stored at room temperature away from bright light.

Four, ** different.

Fresh milk: Because it's right.

Milk source. The requirements are high, the requirements for the production process are high, and the special requirements for transportation and storage are also high.

Pure milk: lower than fresh milk.

Fifth, the shelf life is different.

Fresh milk: The shelf life is short, usually one week.

Pure milk: has a long shelf life, usually half a year.

Encyclopedia. Milk.

Hehe, it is said that there are preservatives in milk, but in fact, the people who say these words do not understand the production and processing technology of milk.

Whether it is pure milk or fresh milk, no preservatives will be added, there is no suspense about this, but there is no guarantee here (add other additives).

At present, dairy products on the market are roughly divided into three categories: fresh milk, pure milk, and yogurt. Of course, there are many reconstituted milks, flavored milks, functional milks, lactic acid bacteria drinks, etc.

In the heating process, there are two processing methods, the higher the temperature, the lower the nutritional value.

At present, there are two main types: pasteurization (62 degrees -85 degrees), commonly known as fresh milk and UHT (135-160 degrees) to promote pure milk. Of course, pasteurized is better than UHT

It should be more nutritious.

In addition to the nutritional value, there is also the taste, because of UHT sterilization of pure milk, the protein will become bitter with the increase in temperature, and the taste is far less mellow than fresh milk, what should I do? Add flavor, so there must be flavor in pure milk with pure milk, which is no longer a fact.

Why is there a difference, in fact, the difference is determined by two aspects, first, the difference in milk source, you know, pure milk does not have much requirements for milk source, but fresh milk has very high requirements for milk source, and there is an obvious difference.

Second, the difference in loss and transportation costs, the shelf life of fresh milk is 7 days, and the cost of the whole cold chain accounts for more than 30%-40% of sales, but pure milk is not 10%, so how can fresh milk not be more expensive?

Pregnant women must supplement with all protein, calcium, and vitamins during pregnancy, so fresh milk is a must.

Note: It is best to drink fresh milk within the shelf life, and do not boil it for sterilization, otherwise it will destroy its nutritional properties. Don't boil it and add sugar, this is a big taboo.

The first sterilization method is different, fresh milk is sterilized at a low temperature of 85 degrees, and pure milk is sterilized at a high temperature of 132 degrees.

Second, the storage temperature is different, pure milk is stored at room temperature, generally stored for half a month. Fresh milk can be stored at a low temperature for up to one week.

Thirdly, the nutritional value is different. Fresh milk is sterilized at low temperature to preserve the nutrients in fresh milk to the greatest extent. Pure milk loses nutrients after high temperature sterilization, especially calcium and vitamins.

1. Fresh milk: Fresh milk is made of fresh milk as raw material, which has been heated at a low temperature of 85 degrees, so it is also called pasteurized milk.

Pure milk: Pure milk is also made from fresh milk, but the temperature during high temperature sterilization is extremely high, and the temperature needs to reach at least 130 degrees instantly.

2. Fresh milk: Fresh milk is only treated at low temperature to inactivate most of the bacteria, but there are still some high-temperature resistant bacteria to survive, and the shelf life of this milk will not be very long, and it can generally be stored for 5 7 days.

Pure milk: Although pure milk is only treated by instantaneous heating, due to the instantaneous temperature is too high, all the fungi in the milk are eliminated, and the shelf life will be extended a lot, and it can be stored at room temperature for 1 3 months.

3. Fresh milk: The heat treatment of fresh milk is pasteurization, the temperature is low, although the time is longer, but the loss of nutrients to the milk is very small, and the nutritional value is high.

Pure milk: Pure milk is heated at high temperature, although the heating time is shorter, but the nutrients in the milk are lost, and the nutritional value is much lower than that of fresh milk.

4. Fresh milk: Fresh milk is currently the most consumed milk due to less nutritional damage, which is higher than ordinary pure milk.

Pure milk: Pure milk has a market share of no more than 10%, and it is relatively low, except for a little longer shelf life, there are no other advantages.

The sterilization method is different: fresh milk is milk that has been heated at a low temperature of 85 degrees. Pure milk, on the other hand, is an instantaneous high temperature of 132 degrees Celsius, which can kill the microorganisms in the milk.

The shelf life is different: the shelf life of pure milk generally ranges from 1 month to 6 months, while the shelf life of fresh milk is up to one week. <

The sterilization method of the two is different, and fresh milk is milk that has been heated at a low temperature of 85 degrees Celsius. Pure milk, on the other hand, is an instantaneous high temperature of 132 degrees Celsius, which can kill the microorganisms in the milk.

The shelf life of the two is different, the shelf life of pure milk generally ranges from 1 month to 6 months, while the shelf life of fresh milk is up to one week.

The nutritional value of the two is different. Because the temperature of fresh milk is not high, the sterilization method of fresh milk can also preserve the nutrients in the milk to the greatest extent while killing harmful bacteria, while pure milk loses more nutrients after high temperature sterilization, especially calcium and vitamins. Fourth, the storage location of the two is different, and fresh milk needs to be stored at low temperature during the storage and sales process to inhibit the reproduction of bacteria.

Pure milk only needs to be stored at room temperature and protected from light.

Fresh milk and pure milk are two different milk products. Although they are both made from cow milk, they differ in many ways.

First of all, fresh milk refers to those that have not been processed or processed. The milk is usually obtained directly from the farm and can be eaten without being sterilized. Pure milk, on the other hand, refers to a product that has been sterilized and processed to remove the fat and lactose, and the nutrients in it are easier for the human body to digest and absorb, and have a longer shelf life.

Secondly, there are also differences in taste and flavor between fresh milk and pure milk. Fresh milk usually has a rich, milky flavor and smooth texture, and it has been confirmed that for many people, this taste is irreplaceable. In pure milk, this milky flavor and flavour are much reduced through processing, and are usually lighter and less picky.

Finally, fresh milk and pure milk also differ in their uses. Fresh milk is commonly used in cooking and making dairy products such as cheese and cream, among others. Plain milk, on the other hand, is more suitable for direct drinking, or for making nutritious drinks or preparing meals.

In summary, although both fresh and pure milk are made from fresh bovine milk, there are many differences between the two products in terms of milk processing, taste, and use. People can choose different products according to their needs.

The difference between pure milk and fresh milk is manifested in the sterilization method, shelf life and nutritional value, pure milk will be sterilized at high temperature through travel and consumption, and can be stored for 1-6 months, but the nutritional value is low, while fresh milk will take the method of low-temperature sterilization, and the preservation time is only 7 days, but the value of marketing and selling is higher.

1. Sterilization method

The difference between pure milk and fresh milk is reflected in the sterilization method. Pure milk will be sterilized using a professional sterilization system, which can quickly raise the temperature to 132 degrees and kill the microorganisms in the milk, while fresh milk will be sterilized by heating and the temperature will be kept at 85 degrees.

2. Shelf life

The shelf life of pure milk and fresh milk is different. In the process of packaging and sterilization, pure milk will minimize the chance of bacterial growth, so it can be stored for a long time, which can be stored for half a year, while fresh milk can only remove most of the bacteria in the milk, so the storage time is shorter, only one week.

3. Nutritional value

Pure milk will use high temperature in the process of sterilization, and high temperature will kill bacteria at the same time, it will also eliminate nutrients, resulting in a decrease in its nutritional value, while fresh milk can maximize the retention of nutrients in milk in the process of sterilization, so its nutritional value is higher.
