We can enjoy the great taste of fresh milk thanks to technologies such as pasteurization. The technology is one still in use today, although founded about two centuries ago by a man known as Louis Pasteur. It alone has developed the food industry as it is apparent today.
The problem with the pasteurization process is that it can remove the taste from the products it cleans. It cleans a product by super heating it to a high degree of temperature. While that certainly kills all the bacteria, it also degrades the quality of the product. This is why organic milk, or milk you’d find fresh at a farm, tastes much better than pasteurized milk.
Nutrients that are in milk are great for growing children. There are helpful vitamins, enzymes, and other ingredients that growing children need for healthy bodies. Pasteurization takes out some of the benefits thanks to the heating process. Some companies will put fortified nutrients back into the milk to make up for the degraded quality, although this will cost more to the consumer.
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.
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.
