Homogenized Vs Pasteurized Milk: Differences in Procces and Benefits of Result

Pasteurized and homogenized milk

Drinking milk has been a part of our health for many years. Milk is rich in vitamins, including vitamin B2 and vitamin B12, vitamin D, vitamin A, and D. It also contains calcium, pantothenic, selenium and biotin, which can help our overall health. We will be discussing homogenized and pasteurized milk in this essay.

What is homogenized milk?

Pasteurization and homogenization are two completely different processes. You can have pasteurized milk without homogenization or vice versa. Many people don’t know the difference between homogenization and pasteurization. This is why most milk on supermarket shelves is both homogenized or pasteurized. Most people are familiar with pasteurization. Pasteurization involves heating and cooling milk quickly to kill microbes and germs.

There is a difference between pasteurized and homogenized milk

Homogenization can be described as a mechanical process that doesn’t require any additives. Similar to pasteurization, there are arguments for and against homogenization. Large-scale dairy farms can homogenize milk without difficulty because it allows them to mix different milks from different herds. Homogenization prevents cream from rising to top. This makes the milk more appealing to consumers. It also gives large farms the ability to ship further distances and work with more retailers. Dairies can homogenize milk to make two percent, one percent, and skim milk easier by removing the fat. As with all mechanical processes, homogenizing milk not only changes the size of fat globules but also rearranges the fat and protein molecules, which can alter their function in the human body. It is the next step following pasteurization. It is used by manufacturers to modify milk for human consumption. Pasteurization is heating milk to kill bacteria. Homogenization involves processing milk so that it does not separate. The result is a well-mixed beverage with the same consistency across all the milk products. Homogenization allows dairy to filter out fats and make skim, one, and two percent milks.


During processing, homogenized milk goes through small tubes. These tubes reduce the size and weight of fat molecules in milk. This allows the oil or fat portion of the milk to be mixed with the water. After heating, the white cells in milk form during pasteurization. This is reversed by homogenization, which redistributes the white cells throughout milk.

Harmful facts

  • Homogenization can be a bad thing. This reduces the number of fat molecules in milk. Your body may be able to absorb fat more easily if there are fewer fat molecules.
  • Homogenized milk also has a smaller size protein molecules, which means that the protein is not absorbed but rather passed through the body.
  • This means that homogenized milk, even though it was always said that milk is healthy, could lead to poor nutrition and weight gain.
  • It could also contribute to hardening of the arteries or other heart problems.
  • Homogenized milk can also contain harmful hormones.
  • Some research has shown that these hormones can cause cancer.
  • The homogenization process reduces the size of fat molecules to be able to bypass digestion. Milk’s natural hormones, and the hormones cows get to produce more milk, also bypass digestion. These hormones interact directly with your body’s hormones.
  • Homogenization makes it easier to absorb fat.

Pasteurized milk

Pasteurization was first created by Louis Pasteur in 19th century to preserve wine for longer periods of time. Heat-treating kills heat sensitive pathogens to lower the risk of developing zoonotic disease such as E. Coli and salmonella. Pasteurisation is an important safety measure to reduce pathogenic bacteria in raw milk. It is required by most countries to be able to sell unprocessed milk products. Pasteurization has a secondary advantage in that it extends product shelf life when stored under refrigeration.

Pasteurization is a heat treatment that is less than F0=3, which is the minimum heat treatment required to sterilize food. This is equivalent to heating at 121.1degC (for 3 minutes). Pasteurization is a gentler heat treatment option than sterilisation. It can be used at temperatures ranging from 60degC up to 115degC.


This is not only possible because of the cool pack in your kitchen, but also the special treatment that milk and other foods receive before reaching your home. Pasteurization is where fresh foods are briefly heated to kill bacteria and then quickly cooled before being shipped to supermarkets. Pasteurization is a key food preservation technology that has greatly increased the shelf life of packaged foods.

Non-pasteurized milk is not as nutritious as other types of milk. This makes it unique and means that you don’t need to worry about serious health problems. There are many other problems that can arise when you use other types of milk. If you’re concerned about getting enough nutrients, ensure you only drink pasteurized milk.

Pasteurization has many benefits

  • Pasteurized milk can contain pathogens that can cause food-borne illness. This can lead to hospitalization, death, and even death. Because milk can be contaminated in many ways, this is why it may not be safe to drink.
  • Pathogens can be transmitted through water, feces, soil, and soil.
  • Pasteurization can kill or reduce microorganisms like Salmonella, Listeria and E.coli.
  • Some claim raw milk is better for you, as it has a higher nutritional value and can cure diseases.
  • Pasteurized milk does not have any scientifically proven health benefits.
  • For children, pregnant women, and the elderly, it is strongly discouraged.
  • People with weak immune systems are at greatest risk from food borne illnesses caused by pasteurized milk or milk products. Additional risk for miscarriage is also present in pregnant women.
  • Pasteurization kills all pathogenic bacteria, yeast, and mould. It also kills 95% to 99 percent of other bacteria.
  • This vitamin is added to pasteurized milk. It promotes calcium absorption and plays an important role in bone health.
  • Only the levels of vitamin B2 or riboflavin decrease during pasteurization.
  • Pasteurized milk remains an important source of vitamin B6.
  • Pasteurization milk has a low risk of getting sick. You can feel confident that pasteurized milk is free from any contaminants that could make you sick.
  • It’s important to be aware of this because it can cause headaches both literal and metaphorical. You will drink healthier milk if you err on the side of caution.

Pasteurized milk has an impact

Pasteurization can lead to a decrease in the quality of milk. Pasteurization not only kills bad bacteria and pathogens but also severely damages or kills some of the most vital nutrients in milk. These nutrients are what make milk the nutritious, whole food it claims to be.

Insufficient nutrients

Although it might seem paradoxical to say that pasteurized milk contains fewer nutrients than natural-occurring counterparts, the truth is that fortified minerals are added to pasteurized milk. This is because many of the fortified nutrients and minerals aren’t as bioavailable to us as our naturally-occurring counterparts. While you may be enjoying good tasting milk, it doesn’t provide the same benefits.

Many hormones and synthetic byproducts are often found in pasteurized milk. Although many of these are safe, humans have not been exposed to them for long enough to notice any side effects. The jury is still out as to whether they are safe for us over many years. You can have homogenized pasteurized milk and pasteurized milk without having been homogenized.


Pasteurization is superior to homogenization. This is the main difference between homogenized and pasteurized milk. Pasteurization can have a limited effect on vitamins found in milk. Pasteurized milk is the best way to reap the health benefits of milk.
