If you observe all the types of milk packages closely, you will notice that different packages have different labels. The labels indicate the type of milk it is. You should understand the meaning of these labels so that you can purchase the right type of milk. Mentioned below are a few common labels you will find on different types of milk packages and their meanings:
Pasteurization of milk was discovered in the 19th century when a scientist realized that heating milk to a very high temperature and then bringing it back to a low temperature before packaging can make the milk stay fresh for a longer period of time. Today, pasteurization of milk is a very common practice in the commercial market. In this process, milk is first heated to 71.7° C for nearly 15 seconds to 20 seconds and then its temperature is quickly brought down to 3° C. This heat treatment is called the ‘High-Temperature Short Time’ (HTST) process. This is one of the most healthy milk options and helps to ensure that the milk you are drinking is safe for you and your family members.
Ultra-high temperature (UHT) Milk
UHT or ultra-high temperature milk is very similar to HTST milk. However, its UHT pasteurization method is slightly different from HTST milk. Unlike pasteurized milk, UHT treated milk has a very long shelf-life and can last a few months. In the ultra-pasteurization method, the milk is heated even at a higher temperature. Besides killing the pathogenic microorganisms present in the milk, the UHT process helps to eradicate many nonpathogenic microorganisms as well that spoil the milk in a few days. Once the UHT process is completed, the UHT treated milk is packed into sterilized milk tetrapacks. Even if you leave them unrefrigerated, the milk will stay good for months. However, you must keep the milk refrigerated and consume it within a few days after opening the milk tetrapack.
The homogenization process is essential to give milk its white color and smooth texture. If you drink milk that has not been homogenized, you will notice a layer of cream on the top. It should be shaken well before drinking to achieve consistency. However, commercial homogenization became very popular in the 19th century. In this process, the large fat globules are reduced to minute particles that get mixed in the milk evenly. It is done by forcing milk under high pressure through small openings. This makes the milk taste creamier. Hence, the homogenization process is used by the dairy industry to make your milk more delicious and nutritious.
