As is well known by the people, now have so many dairy products on the market, ranging from liquid milk, milk powder and sweetened condensed formula.
Many types of milk are present in the community. Viewed from the manufacturing process, the milk has advantages and disadvantages. Here's what you must know in order to provide the best for the little guy.
To remove and kill bacteria to grow, the milk must be heated in the temperature and period of time. Unfortunately, the content of milk (vitamins and minerals) that are on it are very sensitive to air temperature. If heated too long, then the bacteria will die.
However, the nutrients would be a lot missing. Conversely, when the temperature is less heat, bacteria will still be there, but nutrition can still be supplied by the dairy for those who consume them. Well, yuks peep some types of milk based on the drafting process:
UHT Liquid Milk
With the system of Ultra High Temperature (UHT) milk will be heated 135-140 degrees Celsius in just 2-4 seconds. Not long enough to eliminate the nutrients contained in it.
In contrast, whole bacteria (pathogens and spoilage) were dead and sterilized. During the packaging has not been opened, the temperature in the milk will be the same as when placed in the room with a certain temperature. During 6-10 months, the milk can still be stored and consumed.
No need to fear with a preservative. UHT liquid milk is free of preservatives. All thanks to aseptic packaging are specially made in six layers to keep the milk remains in a sterile condition within a specified period without other chemicals (preservatives).
When observed, UHT liquid milk provides the most benefit. Do not bother taking it. Simply open the package and pour into a glass. Little else will easily do it!
In the pasteurized milk is experiencing, the milk must be heated by 72 degrees Celsius for 15 seconds. Heating process is only briefly makes bacterial pathogens are dead.
Spoilage bacteria are still there. That's why pasteurized milk is not durable when not stored in a refrigerator with a temperature of 5-7 degrees Celsius. That, too, only lasted for 14 days.
Using the retort, the milk will be heated 120 degrees Celsius for 15 minutes and caused a whole dead bacteria. Unfortunately, the spores will still be growing. In addition, most of the nutrients disappear during the heating process. Milk is only going to be consumed before passing the six-month storage period.
There are two types of milk powder, full cream and skim milk. For two hours, the milk will be dried with a spray dryer or roller dryer is 200 degrees Celsius. Facing some of the missing nutrients, fortification done again. You just may save the milk powder for two years.
