Practical application:
Want a kind of sterilization method for milk, can kill the pathogen that is harmful to health already can make milk qualitative produce change as far as possible less. According to be able to bear high temperature namely extremely strong n/TB bacterium heats to death curve and the difference principle that the cream that is affected by heat most easily in milk qualitative heat breaks up curve, below low temperature long time or a kind of method that the short time below high temperature undertakes heating processing. Among them, heating for 30 minutes below 60℃, as a low temperature sterilization standard, has been widely used in the world. Using high temperature treatment, although effects on milk quality is somewhat, but can strengthen the sterilization effect, this method is called high temperature sterilization (sterilization), which is above 95 ℃ heat for 20 minutes. Pasteurization can be applied to fermented products in addition to milk.
Milk sold in bags is usually pasteurized. The factory takes fresh milk, processes it at low temperature and then pasteurizes it. Bags of milk produced this way usually last longer. Of course, the specific process and process is much more complex, but the general principle is that.
It should be noted that drinking fresh milk is not safe, as it may contain bacteria that are harmful to our health. Another point is that pasteurization is not a panacea. Pasteurized milk still needs to be stored at a lower temperature (usually <4℃), otherwise it may change its quality. So many of the ways in which packaged milk is sold on the market are quite unregulated.
Pasteurized milk is the most consumed milk varieties in the world. The consumption of pasteurized milk in the United Kingdom, Australia, the United States, Canada and other countries accounts for more than 80% of liquid milk. In the United States, virtually all of the milk is pasteurized, and it comes in large packages (1 liter, 2 liters, 1 gallon), and people go to the supermarket and buy enough milk for a week. Sterilized pure milk is rarely sold in the market, and some small towns cannot buy it at all.
Pasteurization of pure milk can preserve the nutrition and natural flavor of milk, which is the best among all milk varieties. In fact, as long as pasteurized milk is stored at about 4℃, the bacteria multiply very slowly, and the nutrition and flavor of milk can remain unchanged for several days.
The market pasteurization machine is mainly used for commercial purposes, and pasteurization is also the international general sterilization standard, in many large enterprises are used, the market of pure milk other flavors of yogurt are pasteurized. At any time the development of green health food, pasteurization machine is used in many small dairy farms, small dairy farms are used are very 100 liters or 200 liters, mainly to make fresh pure milk, to the market distribution. Pasteurization machine is equipped with a cold water circulation system, the usual way of refrigeration there are two, one is: compressor refrigeration, this way of refrigeration is fast, good effect, also a way of refrigeration is cold water circulation refrigeration, mainly to use physical cooling, will be a lot of lower cost.
