The fresh milk get from cows are healthy?
Why we need milk pasteurizers? Normally, healthy cows can drink their fresh milk. We don’t drink milk from cows and then we drink raw milk, it has all kinds of bacteria in it, so it has to be disinfected. Disinfection, there are two ways, one is the low temperature disinfection method, 60 degrees, 70 degrees, this is called pasteurization, was invented by the French famous microbiologists Pasteur, after the disinfection, it can give some harmful bacteria to kill, but because it is the temperature is not high enough, so it will have other bacteria, And then the bacteria will multiply, and then the milk will probably turn sour and go bad, so this way he sterilizes it, he pasteurilizes it and he has to refrigerate it, and even if he does refrigerate it for a while, he can’t drink it anymore, just for a week.
Domestic more than the need to be refrigerated pasteurized milk, but that can be kept at room temperature, the milk is ultra high temperature sterilization, 100 – degree heat, whether harmful bacteria or harmless bacteria, all killed, no bacteria that can be kept at room temperature, but also can save a long time, a few months, no problem, But you gave me a choice. I should have pasteurized milk.
