The Mini Dairy Plant Produces Sterilized Milk

  • Milk is the first thing that mammals consume after birth, rich in protein, vitamins and minerals. But it won't last long. That's because raw milk is also full of bacteria. The time it stays fresh depends on how it is handled.
    Most Mini Dairy Plant products produce pasteurized milk that can be stored in the refrigerator for about a week if it is not opened. If unopened, milk heated to temperatures above 135 C (275 F) can be stored at room temperature for up to 6 months. But ultra-high temperature milk is not very good.
    Scientists have developed a new technology that not only makes milk safer, but also preserves it for nearly two months when it is refrigerated. Moreover, its taste is as good as fresh milk. During the test, volunteers detected little difference in color, taste or odor within 36 days of processing.
    This technology only adds a fraction of a second to the low temperature pasteurization process. The French chemist Louis Pasteur invented this method in the 19th century, heating the milk to a temperature of 70 - 120 C (158 - 248 F) to kill the bacteria. The higher the temperature, the longer the heating time and the safer the milk. But heating can also distort proteins, destroy vitamins and minerals, and make milk taste bad.
    Here is how long different types of milk can last:
    Pasteurized milk: If unopened, at room temperature for up to 4 hours. If refrigerated below 4 C (40 F), 5 to 7 days.
    Filtering milk: If the unopened filtered milk is stored for up to 45 days at a temperature of up to 7 C ( 45 F ), the sour bacteria are filtered through a fine filter.
    Ultra high temperature milk. UHT milk is heated to at least 135 C (275 F) for two to four seconds and stored in a special package that can be left at ambient temperature for six months if unopened. Once opened, it should be refrigerated and treated like fresh milk.
    Frozen milk: three months.
    Evaporation / condensed milk: one year at ambient temperature.
    Milk powder: powder form, up to one year.
