Can you still eat rice when it expires, and can you still eat expired rice?

Rice is generally not eaten when it expires.

Expired rice loses its nutrients, mildew occurs in a specific environment, and Aspergillus flavus will appear after a long time. Vacuum-packed rice has a shelf life of up to twelve to eighteen months, and the quality of rice is good, and in general, the shelf life is comparatively long.

For imported food, especially ordinary food, it should be consumed within the recommended shelf life. However, the content of lysine and threonine in rice protein is less, so its nutritional value is not as good as that of animal protein.

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.

How to deal with expired but unopened rice:

1. The rice is not opened but cannot be eaten after it expires. If it has just expired, it is not a big problem because it is not opened, but the nutrients will be lost.

2. Expired and unopened rice must not be eaten. Even if the surface is not wet, does not change flavor, and does not change color, it should not be eaten. If you have poultry and livestock at home, you can grind rice into flour and use it to feed livestock and poultry.

But if the rice is moldy, don't feed it.

3. It can be used as fertilizer for flowers. You can use the fire burning method to mix the spoiled rice with firewood, paper and other flammable things to burn into ashes, and when the temperature drops, it is a good fertilizer to sprinkle on the ground, and the effect is similar to that of plant ash. Or bury it in an open field, water it, and in about a week or two the fertilizer will be ready.

How to store rice:

1. Bottled oxygen-free preservation method.

Spread out the rice in a ventilated place to dry thoroughly, and then put it in the prepared jar, jar, bucket or sealed bag, beverage bottle, and cover it with a tight lid, and the utensils for holding the rice should be clean and well-sealed. If you use a cloth bag to pack rice, you should put a plastic bag on the outside of the cloth bag, tie the bag tightly, and put it in a cool and dry place, so that the rice can be stored for a longer time.

2. Zanthoxylum pepper insect prevention preservation method.

Sichuan pepper is a natural antioxidant with a special fragrance and insect repellent effect. Put 20 to 30 peppercorns in the pot, add an appropriate amount of water to boil the peppercorns to make them fragrant, remove the pot from the heat, put the rice bag into the pepper water and soak it out, take it out to dry, and then pour the rice into the pocket. In addition, wrap a few small packets of peppercorns with gauze, put them on the top, middle and bottom of the rice bag, tie the bag tightly, and put the rice bag in a cool and ventilated place, which can also prevent rice insects.

3. Garlic preserves rice.

Peel out the garlic or bring it on, then prepare a clean big bag, put some garlic at the bottom of the bag, then pour clean rice inside, in the middle of the rice, put some garlic cloves again, and finally seal the bag and the rice inside, and put it in a dry, cool and ventilated place, so that it can effectively prevent the rice from being damp or insects, so as to preserve the rice for a long time.

Can't eat.

It is not recommended to eat unopened rice after it expires. Because the taste and quality of rice during the shelf life are the best, and the rice that has missed the shelf life will have serious loss of nutrients, and the taste and quality will also deteriorate, so it is not suitable for consumption.

When judging whether the rice is edible, you can observe the color of the rice water, which is green or yellow, it can not be eaten, and the color of the rice grain can also be observed, and when the top of the rice grain is black, it can not be eaten, and you can also smell the taste, and after the spoiled rice is sealed, it will produce a peculiar smell.

When buying rice, you can observe the hardness, the higher the hardness of the rice, the higher the protein content, you can also observe the color of the rice grains, among which the rice with whiter grains belongs to the new rice, you can also observe the label, and choose the rice with the production date closer to the selection date for purchase.

Identification methods of rice:

1) Look at the hardness: The hardness of rice grains is mainly determined by the content of protein, the stronger the hardness of rice, the higher the protein content. The higher the transparency, too. Generally, new rice is harder than old rice, rice with low moisture content is harder than rice with high moisture content, and late rice is harder than early rice.

2) Look at the belly white: There is often an opaque white spot on the abdomen of rice, which is called "heart white" in the center of the rice grain, and "outer white" in the outer abdomen. The white part of the abdomen has a lower protein content and more starch.

Generally, the moisture content is too high, and the rice that is not ripe after harvest and is not mature enough, the belly is white.

3) Look at the waist burst: The waist burst is caused by the rapid heating of rice in the drying process, and after the rapid heating phenomenon, the internal and external shrinkage of the rice grains is out of balance. When popping kidney rice is eaten, it is rotten on the outside and raw on the inside, and its nutritional value is reduced.

4) Look at the yellow grains: The yellowing of rice grains is due to the chemical reaction of some nutrients in rice under certain conditions, or the microorganisms in the rice grains. The aroma and taste of these yellow grains are poor, so when purchasing, you must observe the amount of yellow grains of rice.

In addition, there are more "dead green" grains in rice grains, and the quality of rice is also poor.

5) Look at the new age: the aging phenomenon of rice is heavier, the color of the old rice becomes darker, the viscosity is reduced, and the original fragrance of the rice is lost. Therefore, it is necessary to carefully observe the color of the rice grains, the rice with gray powder on the surface or with white grooves is old rice, and the more it is, the more old the rice is.

At the same time, pick up the rice and smell whether the smell is normal, if there is a moldy smell, it means that it is old rice.

In addition, look at whether there are insect eroded grains in the rice grains, if there are insect eroded grains and insect corpses, it also means that it is old rice. In addition, to see whether there is insect erosion in the rice grains, if there are insect erosion grains and insect corpses, it means that it is old rice, and to identify rice mildew, mainly from the aspects of rice color and smell.

Expired rice should not be eaten because after the rice expires, bacteria and mold can grow, resulting in a substance called Aspergillus flavus. Aspergillus flavus not only cannot be washed off, but also cannot be completely killed by high temperature, and eating expired rice by mistake can even cause food poisoning, so you should stop eating it immediately when you see the rice turning black and green.

Expired rice is not to be eaten, because expired rice, also known as aged rice, can grow bacteria and mold if stored for too long, resulting in a substance called Aspergillus flavus. Aspergillus flavus not only cannot be removed by cleaning, but also cannot be completely killed by high temperature, and there is no way to clean up the mold and grow per acre.

Eating expired rice by mistake may cause Huangqu Kongxiao mildew poisoning, which can cause gastrointestinal discomfort, diarrhea, vomiting, stomach pain, acid reflux and other symptoms.

2. Oxygen-free rice storage method for plastic bags.

Take a number of non-toxic edible plastic bags with poor air permeability, put every two plastic bags together for later use, spread the rice in a cool and ventilated place to dry, put it into two layers of plastic bags set together, try to fill it as much as possible, squeeze out the residual air at the mouth of the bag with your hands after loading the rice, and tighten the bag mouth with a rope.

3. Kelp hygroscopic storage method.

When storing rice, dry kelp, which accounts for 10% of the weight of the rice, can be put into a rice bag along with the rice, and the kelp will absorb the moisture on the surface of the rice to prevent insects and spoilage.
