Pasteurization Technologies Employed In The Food Industry
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.
Different price points in seemingly the same carton of milk usually are centered around the fact that some milk producers put in extra nutrients and helpful ingredients. This is done to offset the act of pasteurization taking out helpful enzymes, nutrients, and vitamins from the milk. The added benefit is that the helpers are still there, it’s just that the carton of milk will end up costing more.
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.
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.
Closing Comments
Heavy machinery and small machinery alike achieve pasteurization. Finding either will be a tough process, however. Start looking on the Internet for brokers who can help out, start going to local auctions, or buy new from a manufacturer to get started in pasteurization.
