I used to despise the elders who bought large bags and small bags and hoarded food at home.
But with the repeated outbreaks of the epidemic, prevention and control, home... But suddenly realized that "ginger is still old spicy", those who hoard grain at home, it is really ----- "there is grain at home, do not panic when things happen." ”
But then again, for meat, many people buy a large amount at once and then freeze it in the refrigerator.
Will all this pork frozen in the refrigerator be all right? How long can it be stored?
How long can normal frozen meat be left?
In fact, from a theoretical point of view, in the extremely low temperature of freezing preservation, meat bacteria and other microorganisms will basically be inhibited, if you can strictly control the freezing conditions and processes of meat, basically can be frozen for thirty or forty years.
This is really no joke, so those so-called "zombie meat" can actually be eaten.
But the theory is only theory.
There are actually a number of regulations for the shelf life of frozen meat:
What is the maximum freezing time for meat?
First, chicken, duck and goose meat freezing time
The freezing time of chicken, duck and goose meat can be maintained between 3 and 6 months, and must not exceed 8 months.
Once frozen for too long, it will lead to a very bad taste, and it will also cause a large loss of protein and lose its edible value.
Second, beef, sheep and pork freezing time
For beef, lamb, and pork, the maximum period of freezing can be kept at 10 to 12 months.
But the temperature of freezing must be kept below minus 18 degrees. Moreover, in the whole process of freezing, there can be no phenomenon of temperature rise, let alone the behavior of taking out frozen meat for a period of time and putting it back in.
It is easy to breed a large number of bacteria in meat, which is very harmful to health.
Third, vacuum packaging meat freezing time
For vacuum-packed meat, freeze for no more than 12 months.
Although the food is sterilized when vacuum packed. However, in the process of handling these meats, it is very likely that improper handling will occur, which will lead to the emergence of a large number of microorganisms in the meat.
Once frozen for too long, these microorganisms multiply in large numbers in the meat, forming "zombie meat".
How long does it take to freeze before it counts as zombie meat?
The so-called zombie meat is pork that has been frozen for many years, or even aged frozen meat that has been frozen for more than 10 years.
In the process of freezing these frozen meats, there will be a change in the freezing temperature, such as a relatively high temperature, resulting in the deterioration and decay of pork, so that pork belongs to "zombie meat".
But for the average family, if the pork is only frozen in the refrigerator for a few days, or not more than three months, then it is generally not "zombie meat".
In addition, when freezing pork, the temperature of the refrigerator has been maintained between minus 18 degrees and minus 25 degrees. If the pork does not have any rot and odor, such meat is not "zombie meat".
Since frozen meat can be stored for a long time, why can't the "zombie meat" on the news be eaten?
In fact, the "zombie meat" incidents reported on the news are often smuggling problems.
Because it is smuggled meat, its source is unknown, these meat products and meat have not undergone normal inspection and quarantine, transportation and freezing conditions are not up to standard, so the safety risk of such meat use is still very large.
Even if it is not frozen meat, but fresh smuggled meat, there are also these risks, since it can not ensure its food safety, naturally can not eat, let alone market for sale.
In addition, as early as 2007, the state promulgated the "Measures for the Administration of Central Reserve Meat", article 30, there are provisions for frozen products:
In principle, frozen pork is stored 3 rounds per year, and each round is stored for about 4 months;
Frozen beef and mutton are not rotated in principle, and each round is stored for about 8 months.
Therefore, whether as ordinary meat or as a strategic reserve, these meats that have been frozen for decades obviously do not meet national standards and can naturally be eaten.
So, again, the old saying --- don't buy, don't eat!"
