Vacuum-packed cooked food must be quick-frozen at -40 degrees and then stored at -18 degrees to be stored for about three months. If preservatives are added to the cooked food product.

The use of vacuum packaging can generally be stored for 15 days, if it is low temperature storage can be stored for 30 days, but if no preservatives are added, even if vacuum packaging and low temperature storage can only be stored for 3 days, after three days, both the texture and taste will be much worse.

Cooked food is difficult to preserve, vacuum packaging is a common way to store cooked food, so how long can vacuum packaged cooked food be kept?

How long can vacuum-packed cooked food last

Add preservatives.

In general, if preservatives are added to cooked food products, they can generally be stored for 15 days in vacuum packaging, and 30 days if they are stored at low temperatures.

No added preservatives.

Cooked food vacuum packaging can be stored for 5 to 10 days, but the storage time is related to the ambient temperature, when the temperature is higher in summer, the bacteria breed quickly, which may speed up the deterioration of cooked food, and in winter when the temperature is low, it can be stored for about 20 days.

Vacuum-packed cooked food needs to be placed in the refrigerator cold area, where the temperature is low to inhibit the growth of bacteria in the cooked food, or vacuum packed cooked food needs to be placed in a cool place and avoid sunlight to avoid ultraviolet rays to accelerate the deterioration of cooked food.

If there is air leakage or swelling of vacuum-packed cooked food, it should be thrown away and not eaten, because the cooked food has oxidized and caused a large number of bacteria to breed and produce gas, at this time the food has deteriorated, do not continue to eat.

The shelf life of different cooked foods

1. Cooked food.

Cooked food, like the various cooked foods that everyone usually buys, can only be stored for 1 to 2 days at room temperature, while in the state of vacuum packaging, it can be stored for 6 to 8 days, or even about 15 days. But if it takes too long, even vacuum-packed cooked food will spoil, so everyone should consume it within the expiration date.

2. Dried fruits.

Small walnuts, walnut kernels, cashew nuts, pistachios, peanut kernels, etc., which are usually eaten, are vacuum-packed, and if they are preserved, they will be stored for a long time.

Because vacuum packaging can extend its shelf life, in addition, the food of dried fruits itself has a long shelf life, no moisture, and is not easy to breed bacteria, so their shelf life is generally 180 days, that is, about six months.

Generally, cooked food can be stored for about a week after vacuuming.

Vacuum-packed cooked food has different storage times depending on the pretreatment and sterilization methods before packaging. If it is cooked food that has been sterilized at high temperature, it can be stored for 6-10 days at room temperature, refrigerated for about 1-6 months, and frozen for up to 1 year.

If it is cooked food that has not undergone high-temperature sterilization treatment, it can be stored for about 2 days after vacuum packaging and placed in a room temperature room, 4-7 days in the refrigerator refrigerator, and 10-30 days in the refrigerator freezer.

Precautions for vacuum packaging and storage of cooked food

First, it depends on the length of time, there is still a long time before the expiration date, you can leave the refrigerator for the time being, but you must put it in the refrigerator if it is about to expire.

The second is to look at the season, not necessarily in the refrigerator in winter, but in the summer.

Dear, vacuum-packed cooked food can usually be stored for half a month, but in the summer when the temperature is higher, it can only be stored for a week at most.

The main function of vacuum packaging is to isolate bacteria in the air, so as to maintain the effect of freshness, when vacuum packaging is usually used, it can be put into the refrigerator for refrigeration, which can not only better isolate bacteria, but also prolong the storage time.

Questions. I make dried tofu, and recently the customer received the goods and swelled up, how to solve this.

Pressure value reason.

I can only re-ship the goods to the customer.

1.The barrier property of vacuum packaging bags is insufficient;

Questions. Isn't the vacuum time shorter.

After vacuum packing, the aerobic plane works.

The sterilization of vacuum packaging bags is not complete.

These can all lead to problems with vacuum packaging.

Vacuum-packed food will bulge when brought from a low altitude to a high altitude, and the food inside will bulge when it goes bad.

In the process of meat product processing, through the effective cleaning and disinfection of meat raw materials, space environment, desks, equipment, and tools, and the pathogenic bacteria and microorganisms in the residues can be completely removed, so as to produce high-quality meat products that meet the health requirements, and play a positive role in the extension of the storage period of meat products.

Unqualified outer packaging can allow oxygen or water vapor to enter the finished package, promote the reproduction of microorganisms, and lead to mold, mildew and bag expansion of food.

The reasons of the food itself, including the incomplete sterilization of food raw materials, utensils, and environment in the production process, and the reproduction of microorganisms in the environment of trace oxygen or high humidity, can easily lead to mold, mildew, and bag expansion.

Cooked food is vacuum-packed, which can only be kept fresh for 4 days to 1 week in summer, and can be kept fresh for up to 15 minutes in winter and spring, and needs to be refrigerated. For all kinds of food, the storage time at room temperature after vacuum packaging is different. Usually from the empirical point of view, fresh agricultural and sideline products or slightly processed meat products can be stored at room temperature for 2 days, after vacuum packaging, it can be extended to 6 days, and some can be extended to 18 days; Dry foods can last up to 12 months, while cooked foods can be shorter.

The principle of vacuum packaging:

1. Reduce the oxygen content of packaged food, prevent it from mildew, maintain the color and flavor of the food, and prolong the shelf life.

2. Although vacuum packaging has a great role in food. However, if it is used in the processing of clothing products, it has the same effect.

3. Compared with the general packaging method, vacuum packaging can reduce the space occupied by the items. Moreover, it has the advantages of moisture-proof, dust-proof, and anti-bacteria, which makes the transportation of clothing items more convenient.

4. Greatly reduce the possibility of losses caused by certain accidents.

It can be stored for about 20 days in winter when the temperature is low.

If it is not sterilized after vacuum packing, it will hardly extend the shelf life of cooked food. Because cooked food is very watery and nutritious, it is easy to breed bacteria, and sometimes vacuum sealing accelerates the spoilage of some foods. However, if sterilization measures are taken after vacuum encapsulation, the shelf life varies from 15 days to 360 days according to different sterilization requirements.

For example, dairy products can be stored at room temperature within 15 days after vacuum packaging and microwave sterilization, and smoked chicken products can be stored for 6-12 months or even longer after vacuum packaging and high temperature sterilization.

Precautions. 1. Try to choose food vacuum packaging bags without coating and coating. In modern packaging design, in order to make the packaging more beautiful and corrosion-resistant, a large number of materials with plating are used.

This not only brings difficulties to the materials and reuse of products after they are scrapped, but also most of the coatings themselves are toxic, and if people eat these food bags and packaged food, it will cause great harm to people's bodies.

2. Vacuum-packed cooked food needs to be placed in the refrigerator refrigeration area, and should be stored at room temperature to avoid direct sunlight. In addition, if there is swelling and air leakage, you can no longer eat it.

Vacuum packaging must be quick-frozen at -40 degrees, and then stored at -18 degrees in order to be stored for about three months.

If preservatives are added to cooked food products, they can generally be stored for 15 days using vacuum packaging, and can be stored for 30 days if they are stored at low temperature, but if no preservatives are added, even if vacuum packaging is used and low temperature storage can only be stored for 3 days, after three days, both the texture and taste will be much worse.

4. After the vacuum packaging is opened, if the cooked food inside does not produce peculiar smell and white mildew, then it can be eaten directly.

Can be saved up to 3 to 5 days or so.
