Vacuum packed rice has just been opened and has a bad smell, can the rice still be eaten without air

Yes, vacuum-packed rice has a foul smell when just opened, but it is still safe to eat if it doesn't leak. This is because vacuum-packed rice produces some small amounts of hydrogen and acetaldehyde during preservation, which can make it taste less pleasant. However, even if the rice has an unpleasant taste, as long as it does not leak, it will not affect its taste and nutrient content.

Therefore, you can still consume vacuum-packed rice without worrying about safety.

If there is no mildew, clumping, or discoloration, it can generally be eaten.

Packaged rice that is pumped out of air uses hypoxia to inhibit the respiration of the rice and achieve the purpose of preserving freshness. However, when the moisture is high and the temperature is high, it will also achieve the phenomenon of decay.

After the rice is pumped with air, there are some anaerobic bacteria.

A small amount of mold will also grow, and there will be an unpleasant smell, which can be ventilated and dried to remove.

*Edible**Vacuum-packed rice has a strange smell, but if there is no air leakage, it is edible. It may be that the moisture of the rice packaged by itself is too high, and improper storage leads to deterioration, so you can observe whether the packaging has flatulence or air leakage.

Vacuum rice has been unpacked, found that the smell is serious, it is not recommended to eat, food problems are related to health, in order to ensure the health of the food intake, you can choose to give up eating.

Not recommended for consumption.

After the normal rice is unpacked, there will be a fresh fragrance of rice in the future, and there will be no peculiar smell, and the peculiar smell may be caused by deterioration before leaving the factory, so you need to eat it with caution, or directly find the merchant to replace it.

If the vacuum-packed rice has an unpleasant smell when it is just opened, for the sake of prudence, it is not recommended to use such rice again, because the normal rice should have a clear fragrance when opened, if there is an unpleasant smell, either the packaged plastic itself is not qualified, or there is a problem with the rice itself.

Of course, don't eat it, although there is no air leakage, but since it has an unpleasant smell, it means that it has spoiled inside.

Vacuum-packed rice if there is a strand. Bad smell. Let's see if it's five, if he doesn't have five, he has this taste?

Could it be that he got into it when he was packing? Something mixed in. That's why there is another door, and such rice can't be eaten.

Don't eat any more.

Then boil a pot and taste the taste, generally speaking, vacuum-packed rice will not be bad, after opening the unpleasant smell, because the vacuum has been too long, the things in it before volatilized.

Rice will have a bad smell after a long time, it may be a little moldy in the grass, you can eat it and wash it clean.

Although the rice did not leak, it had passed its expiration date, or it was moldy in a damp place. In this case, it will have an unpleasant smell.

Why is vacuum-packed Wuchang rice prone to air leakage?

Personally, he mainly does Guozhong to grow Wuchang rice and delivers goods to customers all year round.

The buyer placed an order for Wuchang rice in vacuum, but the package received was often leaking, which could not achieve the purpose of long-term storage, and the disputes between buyers and sellers that occurred as a result of this have been going on all year round, and it is very difficult to explain.

First of all, it is necessary to clarify what is the air leakage of vacuum-packed rice, and secondly, it is necessary to understand why the rice is leaking.

In the usual sense, vacuum air leakage is mainly due to two problems, 1. The vacuum inner membrane is damaged, or the heat seal is not tightly sealed. 2. Vacuum inner membrane expansion bag.

1. There are usually three main reasons for intimal damage. a, the inner membrane is damaged due to violent transportation, b, the rigid friction between the vacuum rice bricks during transportation leads to air leakage, c, the parameters of the vacuum machine are wrong, or the quality of the inner membrane, or the sealing strip during vacuuming, or the problem of vacuum heat sealing.

2. The problem of the vacuum inner membrane is swollen. We know that the lowest temperature in the Wuchang can reach -30 in winter, and -20 in normal times, and even if the temperature warms up, -15 is the norm. At present, vacuuming rice cannot reach an absolute vacuum, usually there is a surplus of 3-5% air, but at the standard atmospheric pressure, it is enough for the rice to form a standard rice brick form after vacuuming.

According to the vacuum pumped under the condition of outdoor temperature -20 in the northeast, under the standard condition of ambient temperature of 25, the excess air in the rice brick will expand, and this expansion can reach +17% according to the temperature difference, which leads to the vacuum of the rice brick to change the environment to become the air leakage state seen by the buyer.

Because there is atmospheric pressure in rice, because there is no atmospheric pressure in a vacuum, the air pressure inside the rice is greater than the outside, so there will be air leakage.

Hello, vacuum rice leakage may be damaged in installation, do not buy if you encounter air leakage, because it affects the quality.

Why does vacuum rice leak? Vacuum rice, it's just that its packaging is vacuum, if the packaging bag has a hole or is accidentally cut, of course it will leak, and this may have problems during transportation, so you have to be careful.

The reason for the air leakage is nothing more than the seal is not sealed, the bag is broken, etc., and we can check accordingly according to the situation.

Note that there is no particular change in appearance: color change. Whether there is insect infestation. Whether it is mildew. If there is no abnormality, it can be eaten with confidence.

You can eat the rice if it doesn't turn yellow, look at the bulk rice in the supermarket, the beige color has not changed, the rice is not damp and moldy, and you can eat vacuum packaging if there is no peculiar smell.

The rice bulging bag is leaking as long as it is within the expiration date.

Inside, the rice has not deteriorated and can be eaten.

Judging whether food can be eaten is mainly based on food hygiene standards. People usually call the grain harvested in the current year new grain, and the grain stored for more than one year as grain. Except for the decline in taste, other quality indicators of grain are similar to those of new grain, but as long as they meet the standards, they can be eaten.

The chemical grains that have been stored for a long time are usually moldy, and most of them have a musty smell, which cannot be directly used as rations, because they contain koji.

Vacuum-packed rice has a peculiar smell to see what causes it, first look at whether the vacuum-packed rice has deteriorated, insects, etc., if everything is normal, it can still be eaten, if the rice has a hala smell1. Is it normal for vacuum-packed rice to have a peculiar smell?

Note that there is no particular change in the appearance of observation: the color changes. Whether there is insect infestation. Whether it is mildew. If there is no abnormality, it can be eaten with confidence.

If the rice does not turn yellow, it can be eaten, look at the bulk rice in the supermarket, the beige color does not change, the rice is not damp or moldy, it can be eaten without peculiar smell, and the vacuum-packed rice expansion bag is within the expiration date.

Inside, the rice can be eaten without spoilage.

The determination of whether food is edible or not depends mainly on food hygiene standards. People usually refer to the grain harvested in the current year as new grain, and the grain that has been stored for more than a year is called grain. In addition to reducing the taste of the grain, other quality indicators are similar to new grains, but they can be eaten as long as they meet the standards.

Chemical grains that have been kept for a long time are usually in the form of chemical grains, most of which have a musty smell and cannot be used directly as rations due to the fact that it contains aspergillotin.

2. Can I still eat rice with a hala flavor?

I think there could be three main reasons for this:

One is that vacuum-packed rice may have precipitated and oxidized the oil in the rice.

Second, some parts of the rice processing process may be stained with oil, which can cause oxidation and changes.

Third, vacuum-packed rice may be contaminated by external grease during storage and transportation, and the grease will seep into the packaging and cause changes.

In any case, it is shown that the barrier property of the vacuum bag is not very high, that is, although it can be vacuum-packed, it lacks the ability to block oxygen in the air.

3. What's wrong with the smell of perfume in rice

The aroma of authentic rice is a natural fresh fragrance, rather than the artificial fragrance added to the surface fragrance of many rice on the market, which is called artificial fragrant rice. It is added with flavor, which is harmful to the human body for long-term use.

But now naturally grown rice is really fragrant, this rice is very expensive, processed rice usually does not add flavor, your rice may be good quality rice, and many of the rice on the market now is a new variety.

The feeling can also be said to be milky.

Can't eat! Because the rice has passed its expiration date, it is old rice.

Summary. Hello dear, glad to answer for you! Vacuum-packed rice has a strange smell, can you still eat it, you can't eat it?

Note that there is no particular change in the appearance of the observation: the face will change. Whether there is insect infestation.

Whether it is mildew. If there is no abnormality, it can be eaten with confidence. If the rice has not changed, it can be eaten, look at the bulk rice in the supermarket, the rice SE remains the same, the rice is not wet or moldy, it can be eaten without peculiar smell, and the vacuum-packed rice expansion bag can be eaten without deterioration during the shelf life.

Vacuum-packed rice has a strange smell, can you still eat it?

Hello dear, glad to answer for you! Vacuum-packed rice has a strange smell like grinding and wildness, can you still eat it, can you eat it? Shouting, please note that there is no special change in the appearance:

Yan se will change. Whether there is insect infestation. Whether it is mildew.

If there is no abnormality, it can be eaten with confidence. If the rice has not changed, it can be eaten, look at the bulk rice in the supermarket, the rice SE does not change, the rice is not wet or moldy, it can be eaten without peculiar smell, and the vacuum-packed rice expansion bag, within the shelf life, the rice has not deteriorated and can be eaten.

If there is a strange smell, one is that vacuum-packed rice may have precipitated and oxidized the oil in the rice. Second, some parts of the rice processing process may be stained with oil, which will cause oxidation and change, and the vacuum-packed rice may be contaminated by the oil in the outer omen during the storage and transportation process, and the oil will seep into the packaging and cause changes. In any case, it is shown that the barrier xing of the vacuum bag is not very high, that is, although it can be vacuum-packed, it lacks the ability to block oxygen in the air.

Of course, there are implications, but a few things will be briefly explained:

1. The vacuum packaging bag of rice bricks is deformed after air leakage, and it is no longer a rice brick.

2. After the air leakage of the vacuum packaging bag of rice bricks, the air is in direct contact with the rice, resulting in the shortening of the shelf life of the rice.

3. After the vacuum packaging bag of rice bricks leaks, the rice will regain moisture and deteriorate.

Tips to prevent air leakage in vacuum-packed rice:

1. Make a package with a carton to avoid air leakage during handling.

2. The temperature of the storage place should not be too low, the packaging should be thickened in plastic bags, and the effect of heat-sealing plastic bags should be paid attention to.

3. Avoid sharp things from scratching the packaging.

The rice is vacuum-packed, and when you receive the goods, you find that there is an air leak, which will definitely affect the quality of the rice. The first thing to do is to contact the merchant to see if you agree to the exchange. You can also look at the production date of the bag, see the color of the rice, and then smell if there is a moldy smell, you can take a photo as evidence, and then contact the merchant to return the product.

No, it will only affect the shelf life.
