Shelf life of coarse grains.

It depends on the way the grains are preserved. The shelf life varies depending on the way it is processed, how it is packaged, etc. For example, vacuum packaging can have a shelf life of 12 months or more. Ordinary packaging may only be a few months old.

Whole grains in bulk.

The shelf life is relatively shorter. In addition, the storage season will also have an impact on the shelf life of whole grains, for example, the summer shelf life of bulk whole grains is 3 months. Autumn and winter are generally 6 months. After the expiration date, the nutrients of whole grains are lost.

What is the shelf life of coarse grains? Under normal temperature and humidity, it should range from 6 months to 12 months. If it is in the north, as long as it is not placed in a warm and humid place, and the storage conditions are normal, the shelf life of rice and flour products can be extended to about 24 months.

However, it is generally more than a year, so it is recommended that you do not consume it at the least. Even if it is not bad, it will not taste good, and the nutrition will be reduced a lot.

The shelf life of coarse grains is related to the way they are stored.

There is an expiration date, and the shelf life of whole grains is ten months.

2. In a dry and dark storage environment, grains that exceed the shelf life for more than one month to one year are still edible, but the taste will decrease. If it is more than a year, it cannot be eaten.

3. The shelf life of grains ranges from 6 to 12 months at room temperature. If it is in the north, as long as it is not placed in a hot and humid place, the storage conditions are also normal, and it can be extended to 24 months. In the south, it usually spoils during the rainy season.

However, once the grain is moldy, it must not be eaten.

Vacuum-packed cereals cannot be eaten after one year of expiration. The shelf life generally refers to the time limit for maintaining the quality of the ingredients under the storage standards marked on the label, and the vast majority of the ingredients have a shelf life, and the shelf life is to ensure the quality of the ingredients.

Expired food is susceptible to bacterial infection, which can lead to chemical reactions.

Aflatoxin is produced.

Nitrosamines, acrylamide.

and other hazardous substances. The taste of expired food will deteriorate, the quality will also deteriorate, various microorganisms will continue to accelerate the reproduction, and eating expired grains will cause adverse effects on the body.

Vacuum packaging can extract the oxygen in the packaging bag and food cells, so that microorganisms lose the environment in which they live, although it can prolong the preservation time of food, but the cereals after vacuum packaging also have a certain shelf life, cereals.

The shelf life varies according to the way it is processed, packaged, etc. Vacuum-packed, the shelf life can reach 12 months or even longer; Plain packaging, it may only be a few months; The shelf life of bulk cereals is relatively shorter. Therefore, cereals that have passed their expiration date cannot be eaten.

It's best not to eat it anymore, although it's a vacuum bag, but it's past the expiration date, there's no way to ensure its food safety, and there may be some molds that can't be seen and are harmful to the body, so don't eat it.

After the shelf life of the vacuum-packed bag cereals has passed, it is best not to eat them.

First of all, look at the vacuum packaging to see if there is swelling and air leakage, whether there is mildew, and then smell the smell and whether there is a peculiar smell, if there is none, you can eat it.
