Milk Pasteurization Uncategorized

What is milk pasteurization? What are the benefits of treating milk with HTST?

As we know, milk contains three kinds of fundamental ingredients: Milk, Sugar, Vitamins and Proteins. The milk which has been obtained directly from the udder of the cow is bacteria-free and is fit for drinking. But no sooner it comes in contact with the milking vessels and the human hands, it starts observing the presence of the health-deteriorating bacteria. Then such kind of milk is not fit for drinking. The bacteria need to be eliminated. But how to do that?

It can be done with the help of pasteurization.

NK Dairy Equipment provides all kinds of dairy equipment. No matter whether you want it for the ghee plant or the milk processing plant, we have everything for every dairy-concerned business like:

What is Pasteurization?

Pasteurization is a heat treatment. It is not particularly beneficial for killing the harmful germs and bacteria present in the milk. But it is also effective as far as the following are concerned:

  • Water

  • Packaged Foods

  • Non-Packaged Foods

Within how many steps does the milk pasteurization machine accomplish the pasteurization?

The machine manufacturers design its mechanism after getting it divided into 4 simple steps which are as follow:

  • Regenerative Heating

  • Cream Separation / Standardization and Homogenization

  • Regenerative Cooling

  • Hygienic Packaging

Does the pasteurization process have the potential to kill the harmful pathogens from the milk?

Pasteurization is one of the most effective physical processes that kill the harmful pathogens present in the milk just by carrying out the heating treatment. This treatment is super beneficial as it is the natural way of destroying the health -0deteuoating bacteria which does not use a single bit of the chemicals.

Is pasteurization also known as HTST?

Yes, pasteurization is also known as HTST. High Treatment Short time heat treatment is what is its full form. In this heating treatment, the milk is heated to the highest temperature that is usually 72 to 75 degrees Celsius for about 15 seconds. And then the next steps aim at letting it get cooled within the shortest possible time. The scientists are also of the view that this HTST process is the ideal process of eliminating the bacteria from the milk.

Which are the primary benefits of using HTST Technology?

The benefits of using the HTST technology for killing the germs are as follow:

  • The consistency of the milk gets improved since microorganisms are removed from the raw milk.

  • The following important aspects of the milk gets improved and maintained:

  • Texture

  • Nutrients

  • Original Flavour

  • Great destruction of bacteria at one is possible

  • The temperature can be controlled up to 1 degree celsius

  • The shelf life gets increased

  • The machines which are used for milk pasteurization are highly energy efficient.

  • With this process, it is quite easy to avoid infections.

  • When the strength and the potential of the milk are increased with this process, then immunity is boosted and energy is intensified.

Milk Pasteurization milk plant

What is the method, temperature and time required to pasteurize the milk?

Do you know it is banned in some countries to provide milk without doing pasteurization procedure? There are lots of disputes around pasteurization. So if you are thinking of opening a milk plant then, make sure you are selling the pasteurized milk. Also, make sure you are having different types of dairy equipment to make multiple varieties made out of milk such as cheese, butter and much more.

Milk Pasteurization

During milk pasteurization milk is heated for some time at a specific temperature. It is heated to kill all the germs as well as bacteria present in the product.

If you will consume raw milk, then there are chances you will experience some problems that are mentioned below:

  • Nausea
  • Puke
  • Pain in the abdomen
  • Failure of kidney
  • Miscarriage

Above mentioned are the reasons why you should consume pasteurized milk. Some people are more vulnerable to the germs that are mentioned below:

  • Kids of 5years or below
  • Senior citizens
  • Women who are pregnant
  • People suffering from HIV, cancers and much more
  • People suffering from diabetes as well as heart problems

These are the group people who are more prone to getting affected on consumption of raw milk. This is the reason why the government has made some rules and regulations for the people who are running a farming business. To avoid any type of health issues make sure you are selling the milk after the pasteurization process.

What is the process of pasteurization?

There is a proper process of pasteurization which includes:

  • The person should need a double boiler.
  • Thermometer
  • You need a large spoon.
  • Ice- water

The foremost step should be done by you is cleaning the area where you are going to do the process. Also, make sure your hands, as well as jars, should be cleaned. You can also boil the containers for some minutes to sterilize. After cleaning, you should put water in the bottom of a double boiler. After that put milk inside it. You should make sure your milk is heating at low flames without burning from the bottom. You can use a thermometer to ensure that the temperature of the milk is under controlled. Keep your milk for sometime after reaching the desired temperature. Then put the whole milk in ice water to cool down.

What is the temperature for pasteurizing the milk?

There are two methods which you can select for pasteurization such as HTST and low temperature, ultra-high temperature.

You need to make sure that the temperature of the milk should be around 63 celsius for 30 minutes for low temperature. It is also known as VAT pasteurization.

HTST stands for high temperature, the short temperature in which you should make sure that the temperature of the milk is near about 72 celsius for 15 seconds only.

Ultra- high temperature needs 138 Celsius to heat the milk. Make sure you are keeping for 2 seconds only.

Milk Pasteurization Milk Processing

What are the common types of Milk Pasteurization and explain some benefits of this process?

Back in 1880, Louis Pasteur, a French scientist, found that heating any food could kill or eliminate undesired micro-organisms and prevent edibles from becoming ruined. After that moment, pasteurization has become a luxury for people when it comes to preserving food.

In order to increase the commodity shelf life, many broad companies use pasteurization. Manufacturers such as food, dairy products, and beverage utilize large-scale pasteurization to ensure that goods satisfy consumer health and food safety criteria. 

Milking machines and dairy equipment are valuable to offer you good quality dairy products. Similarly, pasteurization is also done to provide you quality dairy products.

Types of Pasteurization:

Pasteurization is now classified into three broad categories:

High-Temperature Short Time (HTST)

Also known as Flash pasteurization, this process is the most common method for preserving milk. Milk is then heated for 15 seconds to any pathogenic bacteria at temperatures of around 170° F and above if required. For this process, pasteurized milk must be consumed for reasonable and healthy use within one to three days.


This pasteurization method is used for every milk brand which requires a hygiene or packaging shelf-life of up to one week. This ensures that milk is the easiest and most efficient way to sustain milk at temperatures between 220°F and 230°F within a matter of seconds.

Vat Pasteurization

It is the fastest and most costly way of pasteurizing milk. The milk is heated in a vat for 30 minutes to around 160 ° F and then cooled to a temperature of 40 ° F. It is the safest way to consume unhealthy and unprocessed, fresh milk.

The raw milk is preserved and circulated in either of the above pasteurization processes, preferably before consumption in the cold chain at 4 ° C. The pasteurizing method guarantees that the milk is healthy for longer use. This is why pasteurized packaged milk is popular with most consumers.

Milk Pasteurization Benefits.

Milk heating before packing will have several benefits for us to destroy the bacteria that are present:

  • Reduced chance of disease: The pasteurization method destroys much of the harmful milk bacteria. The risks of illness decline after the intake of this type of milk.

  • Better nutritious value: Because pasteurization destroys bacteria contained in raw milk, milk-based nutrients become accessible to anybody who drinks milk.

  • Increased use: Pasteurization not only serves to eliminate toxic microorganisms from fresh milk but also to retain the processed milk for a longer period of time and allow it usable for consumer use.

Yes, milk pasteurization offers you quality products that are beneficial for your overall health.
