UHT Milk vs. Dairy Fresh Milk – The Differences
In most areas of the Philippines, as well as many other places in Asia and Europe, UHT milk is the only milk you can buy from the stores. UHT stands for either “ultra-high temperature processing” or “ultra-heat treatment”, whichever you prefer.
UHT milk was invented in the 1960s, became generally available in the 1970s, and I consumed my first “box” of UHT milk in 1983.
Dairy Fresh Milk
People of modernized countries don’t realize bad they really have it. Having lived in the United States most of my life, but with the opportunity to live in other countries, I understand why no one notices.
Dairy fresh milk has a very limited shelf life requiring refrigeration and usually only for a few days. The reason? The milk is only pasteurized and homogenized. UHT milk, however, has a shelf life of six to nine months at room temperature. Once opened and refrigerated, that shelf life reduces to a few days, but then it’s already being consumed. Dairy fresh milk will go bad in the refrigerator even if unopened, within two weeks.
The modern consumer tends to throw out more spoiled milk than consumers from developing nations where distribution of dairy fresh milk isn’t practical.
The Taste of Milk
When you live in places like the United States, you tend to get used to the way the dairy fresh milk tastes. It’s pasteurized and homogenized cow milk. Goat milk tastes different, as does the milk from other animals.
UHT milk tastes slightly different from dairy fresh milk, but it’s still cow milk. It doesn’t take more than a couple of days to get used to the difference in taste. I still like to drink it cold even if it’s not necessary, so I always keep a few liters in the refrigerator. I’ve returned to the United States multiple times and I drank dairy fresh milk there and then returned to drink UHT milk here in the Philippines. I hardly noticed the taste difference each time.
Pasteurization vs. UHT
Pasteurization is the process of heating milk to 72 degrees Celsius (161.6 degrees Fahrenheit) for at least 15 seconds. UHT is the process of heating milk to a temperature exceeding 135 degrees Celsius (275 degrees Fahrenheit) for one or two seconds.
Pasteurization takes place before filling dairy fresh milk into containers to kill most of the microorganisms which cause spoilage. The original taste is normally maintained. Although the UHT process changes the taste slightly, it kills all the spores in milk.
You may be Drinking UHT Milk without Knowing it
Rumor has it that the McDonalds’s McFlurries are made with UHT milk. It’s also rumored that UHT milk is the kind of milk served on planes and trains. Neither rumor can be confirmed but if a milk product has a label, you may be surprised as to which type of milk you’re drinking when you inspect that label.
There’s nothing wrong with drinking UHT milk. In my opinion, it’s safer to store and drink due to it’s much longer shelf life. Our UHT milk is imported from New Zealand, where my friend Lis Sowerbutts is currently living.
Speaking of New Zealand, a place where I really want to go for vacation, did you know a lot of American movies are filmed there? If I’m not mistaken, “Lord of the Rings” was filmed there.
Negative Reactions to UHT Milk
I’ve read a lot of negative stories about UHT milk. As usual, the negativity is about how the milk is changed when it’s heated. Some people say it’s no good for cooking or baking. Well, when you cook, you’re going to be heating that milk beyond the boiling point anyway.
It’s almost as bad as how people say that microwaved food isn’t good for you because it changes the molecular structure of the food. Again, when you do any kind of cooking, you’re changing the molecular structure.
If you want to have true fresh milk and completely unchanged food, you need to drink the milk straight from the cow (like farm families do) and eat all of your animal products raw. Good luck with that.
