1 How long is the shelf life of pure milk

The shelf life of pure milk varies according to the different sterilization techniques.

Such as pasteurization method of pure milk, its sterilization temperature of 60-85 ℃, just kill most of the microorganisms in the milk, so the preservation time is shorter, generally only a few days or ten days, up to a month's preservation time; and the use of ultra-high-temperature sterilization technology to deal with the pure milk, the sterilization temperature of at least 132 ℃, can kill all microorganisms in the milk, so the preservation time is longer. All microorganisms in the milk, so the preservation time is longer, up to 3 months, 6 months, or even a year.

2 Pure milk shelf life of 45 days or 6 months of good 1, from the nutritional point of view: shelf life of 45 days of good

The shelf life of milk and its sterilization method, and sterilization methods directly related to the amount of nutrients in the milk, in general, the shorter the shelf life of the milk, the sterilization of milk nutrient loss is less from the point of view of the nutritional perspective of the drinking, better than the long shelf life of the milk.

2, from the perspective of preservation of convenience: shelf life of 6 months good

shelf life of 45 days or less than a month of milk is mostly fresh milk, the transportation and sale of this milk need to be preserved refrigerated, otherwise easy to breed bacteria lead to milk deterioration, and the shelf life of 6 months of milk due to the sterilization is more thorough, only need to be placed in the room temperature to avoid the light preservation can be, relatively speaking, preservation of more convenient.

3, from the sales price point of view: shelf life of 6 months cheaper

Shorter shelf life of the milk on the origin of the milk, production processes, transportation conditions, storage conditions have high requirements, usually expensive, almost twice the price of the long shelf life of pure milk.

3 Pure milk shelf life of 6 months with preservatives

No preservatives.

Many people think that the shelf life of pure milk up to 6 months or even more is added to the credit of the preservatives, in fact, is not so, this is because the shelf life of 6 months of pure milk is made using ultra-high-temperature sterilization technology, which in the process of sterilization, the temperature can reach 135-150 ℃, almost all bacteria can be killed, coupled with more of this milk to take the high barrier film made of sealed box packaging, can meet the milk to maintain the nutrients and ensure the health and safety of milk for a long time to save demand, so the shelf life will be longer.

4 Pure milk shelf life of one year normal

Normal.

Pure milk shelf life of up to one year of milk, its sterilization technology requirements will be higher, the use of instantaneous autoclaving, and its packaging is relatively sealed better than ordinary pure milk, this milk is mostly imported milk, can be preserved for such a long time, mainly to meet the sales demand.

Because imported milk first after the factory inspection, exit inspection and customs inspection of the three procedures, only the country testing about 8 to 10 days, followed by imported milk sea transportation time is generally 30 to 45 days, in addition, customs clearance but also 2 weeks, the commodity inspection to 15 days to 1 month, these times are mandatory, there is no one link can be omitted. Visible bottle of imported milk with a shelf life of 12 months, excluding 2 to 3 months testing and transportation time, shelf life of the last 3 months is not easy to sell the cost of time, the golden sales time is only 6 months or so, which are imported milk had to extend the shelf life of the important reasons.
