Milk contains three primary ingredients: milk sugars, proteins, and vitamins A and D apart from numerous nutraceuticals in minor quantities. Natural Milk as it comes out from the udder of the cattle is free of any germs and bacteria, But once it starts coming in contact with the milking vessels, human hands, and equipment which invariably carries abundant bacteria, milk gets contaminated with these bacteria, some of which can be harmful to for human consumption Hence, like other natural food products, safety must be ensured before consuming milk. This is where pasteurization comes into the picture.
What Is Milk Pasteurization and Where Did It Come From?
Pasteurization is a process of heat treatment of water and certain packaged and non-packaged foods, including milk that is done to kill all harmful / bad microorganisms like bacteria, viruses, or other pathogens
The history provides the benefits of Pasteurization and the rationale behind the same. The process of boiling or heating milk for eliminating health issues has been recognized since the early 1800s and was used to reduce milk-borne illness and mortality in infants in the late 1800s.
As society industrialized around the 20th century, increased milk production and distribution led to outbreaks of milk-borne diseases like typhoid fever, scarlet fever, septic sore throat, diphtheria, and diarrheal diseases.
These illnesses were eliminated with the commercial implementation of Pasteurization, in addition to improved management practices on dairy farms.
Initially established by Louis Pasteur, in 1864, to prevent wines from spoiling, this method is now widely used across the world to keep all health issues at a distance
Additionally, Milk Pasteurization Machine Manufacturers state that Pasteurization is entirely a natural and well-tested method, and is vital in ensuring that the milk is fresh and safe for consumption.
According to the Food and Drug Administration (FDA), Pasteurization doesn’t reduce milk’s nutritional value nor makes it any less natural.
The Milk Pasteurization Machine Manufacturers Formulate 4 Simple Steps for the Process of Pasteurization:
- Regenerative Heating
- Cream Separation / Standardization and Homogenization
- Regenerative Cooling
- Hygienic Packaging

The Power of Pasteurization
Pasteurization destroys potentially harmful pathogens by the process of heating. It is a physical process, and no chemicals are added to the milk. It is an essential step in the food safety system to protect people from dangerous foodborne diseases
The Center for Disease Control and Prevention (CDC) recommends avoiding raw milk as it can cause food poisoning. Keeping this critical recommendation in mind, Milk Pasteurization Machine Manufacturers states that HTST Milk Processing Equipment is used to ensure optimum pasteurization process.
HTST is the acronym, for High-Temperature Short-Time Heat Treatment. The HTST Heat Treatment Processing Equipment is primarily used in milk production and other liquids as well.
In this heat treatment process, milk is heated to 72-75℃ for 15 seconds and cooled again in a fraction of seconds according to the HTST method. It is a safe and well-tested process these days to pasteurize the milk, which is referred to as quick Pasteurization or continuous Pasteurization.
Neologic Engineers have spent years in research & development of the equipment for HTST Milk Processing for milk pasteurization. Download our milk processing pasteurizer brochure to know more.
The Primary Benefits of Using HTST Technology for Pasteurization Include:
- It is useful to improve the consistency of milk by removing micro-organisms and toxic enzymes from raw milk.
- It aims at maintaining the texture, nutrients, and the original flavour of the product due to a shorter holding time.
- A higher rate of bacterial destruction is possible
- Precision in temperature controls, up to 10℃
- Hugely increased shelf life when compared to the previously used HTST pasteurization system.
- These milk pasteurization systems are extremely energy-intensive.
- These devices may be wholly utilized for recycling.
- The expansion chamber in Tubular Heat Exchangers ensures the accuracy of heat exchange and also improves the product quality.
- This process is useful to avoid infections such as scarlet fever and diphtheria, and also strengthens the immune systems.
Conclusion
Pasteurization of milk is, therefore, recommended as it improves living standards and enhances the elimination of various health issues and all this is helpful to make quality milk and other milk products too, as these are valuable to improve health of consumers. Neologic Engineers is known as one of the leading milk pasteurization machine manufacturers and dairy equipment manufacturers. Our range of reliable and sturdy dairy equipment provides exceptional value to dairy plants and juice processing plants.
