How The Typical Milk Pasteurization Process Works

Pasteurization describes the process created by Louis Pasteur. This fellow discovered a method of purifying certain foods and liquids, and it's still in use today. Pasteurization is most commonly known as the reason we can have fresh milk from the farm, days after harvesting.

One caveat with pasteurization is that the process actually takes some of the taste out of the item being sterilized. Because the liquid is being heated to hot temperatures and brought down again, the taste is disrupted. This is why milk that is fresh from the farm, and organic, may taste a bit better than the standard carton of milk from the grocery store.

Taste isn't such an issue in the end. The real fact to consider is that pasteurization has been shown to take out helpful enzymes, vitamins, and minerals that are in milk. Often, the milk you see in stores will have been supplemented with such things to put the healthy materials back into the milk. You may see special fortified milk types, although they cost more money.

Some types of pasteurization can make milk last several months without going bad, as you would see with your average grocery store milk container after a week of opening it. Through special processes such as ultra heat treatment, or UHT, and aseptic packaging, milk can last much longer on the shelf. Of course, if you ever opened the carton, you should obey the throwaway date listed on the container.

Pasteurization is most commonly associated with milk, since that is the industry that arguably uses the devices the most. Other products that use pasteurization include nuts, beer, cheeses, crabs, cream, honey, soy sauce, and more. To see a taste difference for yourself, take a bite of crab that has been pasteurized. Compare the taste to that of the crab that has been freshly caught out of the coast- odds are you will spot a large difference.

In researching pasteurization, you will also come across the art of homogenization. This process achieves about the same effect as pasteurization, only the sterilization process is done differently. Instead of relying primarily on heat, the process collides the contents of the milk with itself, enough that the mixture is completely the same in all parts of the mixture. Unfortunately, this also means the fat is made soluble into the mixture, and that the nutritional content isn't so great.

Final Thoughts

Pasteurization is a fine process that is done with expensive machinery. You should start looking at used and new devices in your area if you believe you would like to start the process of pasteurizing any liquids or foods you have to make them more safe to consume.
