Vacuum packed rice has a shelf life of 18 months, can you still eat it after a year and a half of ex

This of yours should not be mildew. Since it is vacuum-packed, it does not come into contact with moisture. It is not easy to produce mildew.

The rice has been left for a long time, and it can be eaten, but the taste is not very good.

The mildew of rice is mainly related to the temperature and humidity and the amount of bran powder on the surface of the rice.

Timely cool rice as well as pests. The microorganisms that cause the grain to remain unchanged are mainly fungi (molds, yeasts).

plant pathogenic fungi, etc.), bacteria, viruses, etc., and the mold in the fungus is the most likely to contribute to the mildew of rice. In the early stage of mildew, the surface of the rice is gray, tarnished, and ash-powdered, and the rice groove is obvious. The mildew process manifests itself as fever.

sweating, emitting a slight musty smell; The mold itself and the pigments produced by its metabolism cause the rice to change color, so that the original color of the rice grains disappears, and the colors such as black, dark and yellow appear. Mildew and rice moisture content.

Ambient temperature, humidity, and gas composition are significantly correlated. When the moisture is below 12%, it is difficult for the mold to reproduce, and when it is below 14%, the water activity aw value is lower, which has a certain inhibitory effect on some mold spores, and most microorganisms cannot reproduce. Mold is greatly reduced below 20, and pests are completely inhibited from reproduction below 10, and mold stops moving.

How long is the shelf life of rice, and can it be eaten after a year? I just found out, too.

Rice packed in vacuum can be stored for three years, and whether it can be eaten depends on the situation. If the expiration date is shown on the outer packaging and it has expired for a long time, it is best not to eat it, which will not only affect the taste of eating, but also may have a certain impact on the body. But there are some exceptions, some rice, has been vacuum packed, and is not opened, storage is more appropriate, the right environment, the right temperature, in this case, the rice will not have much impact, the seat can still be eaten, although it will not cause serious harm to the body, but it may not taste good, but it is recommended not to eat.

1. The shelf life of rice is generally more than one year. Rice is still a relatively durable food, especially vacuum-packed rice, the general shelf life will be more than one year, but some in six months to twelve months, bulk rice shelf life is a little shorter, generally in summer in about three months, autumn and winter in about six months. Imported rice has gone through the air-drying process, so the shelf life can be as long as 24 months, but whether it can be eaten or not depends on the shelf life time marked by the merchant.

2. Expired rice may cause physical discomfort. If the rice is expired, it is best not to eat it again, although it is vacuum-packed, but if the time is too long, there will be a peculiar smell, and the taste is not good, and there may be some bacteria, such as aflatoxin, etc., after ingestion into the body, it may have a bad effect on the body, causing abdominal pain and diarrhea.

3. How to store rice. Rice is very prone to insects in the summer, so we must take a reasonable way of preservation, you can put the rice in a suitable breathable plastic bag, store it in a cool and dry environment, and you can also store the bagged rice in a large vat filled with quicklime, so that it can absorb the moisture of the rice and is not easy to get insects.

Of course, because it is vacuum-packed, it isolates a lot of bacteria and does not spoil it, so it can be eaten.

If the vacuum rice has not been opened, it has been left for three years, the expiration date has not expired, and the inside has not deteriorated, it should be edible, but the vacuum rice that has been unpacked is not recommended to be eaten after three years.

In general, if it is vacuum-packed rice, it is generally best not to store it for more than a year and a half. For general bagged rice, it is best to store it for no more than one year.

In most cases, as long as the rice is well packaged, there is no musty smell, no peculiar smell, no discoloration after opening, and it can basically be eaten normally, but the time is too long, through air oxidation, moisture in the air enters, and it will be affected by moisture, discoloration, mildew, etc., which will not only affect the taste, but also lose some related nutrients, and may also produce harmful substances.

It is not allowed to be eaten, because rice also has a shelf life, if it has been three years, it is best not to eat it, otherwise it will have a certain impact on your health.

Personally, I feel that it is not edible, because the rice that has been stored for three years may have passed the expiration date, and it is very bad for the body if you eat it.

It is not edible after three years of storage, although it is vacuum-packed, but after three years of storage, its taste has changed.

Of course, you can still eat it after three years of storage, and the nutritional value of vacuum-packed rice is also very high.

As long as it is past the expiration date, it is best not to eat it.

1. Can rice still be eaten after the expiration date?

The rice is expired and cannot be eaten. Because expired rice nutrients will be lost, and mildew and aspergillus flavus will occur in a certain environment. After consumption, it is harmful to the body and can lead to poisoning in serious cases.

2. How long is the shelf life of rice?

The shelf life of rice varies depending on how it is processed, how it is packaged, etc. Ordinary packaging, it may only be 6-12 months; The shelf life of bulk rice is not clearly specified, generally 3 months in summer and 6 months in autumn and winter.

Spring and summer are humid and hot, and the shelf life of rice with high moisture is only 3 months, while imported rice generally has an additional air-drying process, and the moisture is greatly reduced, and the shelf life will be as long as 24 months. The expiration date of the bagged rice is determined by the manufacturer through experiments.

3. Rice storage methods.

1.Storing rice in a low-temperature environment, such as in the refrigerator, can reduce the oxidation of rice oil and the breeding of rice worms.

2.In summer, the weather changes greatly, and rice bran is prone to stickiness, which leads to insects. In the summer, the stored rice can be sieved again to remove the fine bran and store in a ventilated place to avoid insects. Orange peel contains citral, and burying orange peel in rice can repel insects and insects.

3.Use large capacity bottles and fill the rice into the bottles. Make sure the rice is dry, and tighten the lid as soon as you put it in.

4.Liquor can play a role in preventing rice worms. Fill the bottle with 100ml of liquor, open the cap, insert the bottle containing the liquor into the rice, the mouth of the bottle is exposed, and then store it in an airtight rice tank. The ethanol gas volatilized by liquor can prevent rice mildew.

In fact, as long as we pay attention to keeping the rice dry, it is not easy to mold. In addition, we should not hoard too much rice at home and buy it after eating, because the quality and freshness of rice are very important for good health.

It can be eaten, but it is not recommended. The shelf life of vacuum-packed rice is about two years, if the rice is expired, but there is no deterioration, it is possible to continue to eat, but it is not recommended to eat expired rice, such rice will not affect health, but the nutrients in it have been lost a lot, and long-term consumption is easy to cause malnutrition.

Vacuum-packed. The millet expires and can not be eaten, and the shelf life of rice noodles.

It varies 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. However, once the rice noodles become moldy, they must not be eaten.

Only by correctly understanding the expiration date can people eat healthily. Don't buy some food that is about to expire because you are greedy for cheap, which will put your health at risk. The storage conditions of food are crucial to the quality of the food.

The shelf life is usually set according to the relevant suitable storage conditions of this type of food, for example, on the packaging of ordinary biscuits, we can see the words "storage method: avoid sun exposure, store in a cool and dry place, please eat as soon as possible after opening".

The rice is expired and cannot be eaten.

If the rice has passed its expiration date, it cannot be eaten. In fact, rice is still alive after harvesting, and its taste quality will deteriorate over time.

There are three main ways to judge whether rice has deteriorated:

1. Look at the color.

If the rice is dull in color and has no luster, it will naturally not be fresh.

2. Smell the smell.

Fresh rice has a fresh aroma, while spoiled rice smells musty.

3. Look at the packaging.

Some unscrupulous merchants will process the expired and spoiled rice again, modify it and then sell it to various places, such rice usually does not indicate the manufacturer, date and other information, so you must pay attention to this information when buying.

How to dispose of expired rice

1. Feed poultry.

Although the expired rice is not edible, it can still be fed to the poultry, or it is a good choice to go to the square to feed the pigeons.

2. Wash the teacup.

Tea lovers know that cups with tea stains are difficult to clean, especially those with a small caliber. In this case, you can put the rice in a cup, add water and shake it vigorously a few times, and then wash it with water, and the tea stains that were originally difficult to clean can be easily solved.

3. Keep fresh eggs.

Eggs are also one of the foods we stock up on in our daily lives, but they are also very spoiled, and this is when expired rice comes into play. By burying the eggs in the rice, you can keep them fresh, so you don't have to worry about the eggs going bad.

You'd better not eat it, it's expired, it's been too long.
