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.
Technology is a wonderful thing. There are now processes that will allow the average carton of milk last months while on the shelf. You certainly wouldn’t be able to do this with a standard carton of milk found at a modern grocery store, however. With new types of heat treatment, and special packaging, one can find even organic types of milks that only need refrigerated after being opened for the first time.
Don’t forget that the world of pasteurization encompasses much more than milk. There are other foods and liquids that pasteurization has done a world of good for. This would include alcoholic beverages, but also foods like crab and nuts. Imitation crab meat especially is a product that can withstand spoiling, as it can be pasteurized and packaged to be shipped all around the United States. Other items might include cream, soy sauce, honey, and more.
Some side with the act of homogenization. This process is the counter process to pasteurization. In homogenization, the mixture of milk is blended so finely that all parts of the milk are equal. This means that the fats and molecules are all compressed and mixed into one solid mixture. Those who side with pasteurization claim that this process makes for one that removes much of the nutritional content. It also detracts from the overall taste of the milk.
Closing Comments
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.
