How to store rice.

1. Rice utensils should be clean and strict. It is best to put the rice in a jar, jar, bucket and have a tight lid. If you use cloth to bag rice, you should put a plastic bag on the outside of the cloth bag and tie the bag tightly.

2. Soak the cloth bag in the boiled pepper water, put the dried rice in the air-dried bag, and then wrap some new peppercorns with gauze, and put them on the top, middle and bottom of the rice respectively. Tie the bag tightly, so that it can not only prevent mildew, but also repel insects.

3. Mix kelp and rice in a ratio of 1:100 by weight, and take out the kelp every week to dry to remove moisture, which can keep the rice dry and not mildew, and can kill rice worms.

4. Put a few crab shells, turtle shells or shallots in the rice bucket to prevent insects.

5. The storage temperature is best between 8 and 15.

6. Put the rice in a plastic bag, about 5 kg each time, tie the bag tightly, put it in the refrigerator freezer for 48 hours and take it out, do not open it immediately, it can kill pests.

7. At the bottom of the rice tank, sprinkle 1 inch thick grass and wood ash, spread white paper or gauze, pour in the dried rice, seal the container, and place it in a dry and cool place.

It is best not to eat expired food, you can go to the merchant to replace, the merchant must replace it for you, if the merchant cheats, you can react at the Industrial and Commercial Bureau. But it doesn't take long to eat it after it expires, it's generally not much of a problem, I remember when I was a child, I planted my own rice in my hometown, and the old rice that was put for four or five years was also eaten, and it was okay to eat it with a musty smell when it was cooked, and it was okay after so many years, and the bacon was also put for a few years, and the pickles or pickles were also a few years.

Can't eat.

It is not recommended to eat unopened rice after it expires. Because the rice is in the shelf life.

The taste and quality are optimal, and rice that has missed its expiration date will have a serious loss of nutrients, and the taste and quality will deteriorate, making it unsuitable for consumption.

When judging whether the rice is edible or not, you can observe the rice washing water.

The color of the rice grains, when the rice water is green or yellow, it can not be eaten, and the color of the rice grains can also be observed, when the top of the rice grains is blackened, it can not be eaten, and the smell can also be smelled, and the spoiled rice will produce a peculiar smell after being sealed.

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: Rice often has an opaque white spot on the abdomen.

The white spots are 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 high moisture content, unripe and not mature rice after harvesting, belly white is larger.

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 the rice grains is due to the chemical reaction of some nutrients in the rice under certain conditions.

Or it is caused by microorganisms in 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 phenomenon of rice aging.

The heavier, the color of the aged rice becomes darker, the viscosity decreases, and the original flavor 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.

The rice is expired and cannot be eaten.

If the rice has passed its expiration date.

Then you can't eat it. 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.

Hello, you can open it first, and then grab a handful and ask if there is a musty smell, if you feel that there is a clear musty smell, it means mildew, you can't eat it, throw it away.

Another identification method, fingers grab a few centimeters and pinch hard, if you can crush it, it means that the nutrients have evaporated, it is not suitable for consumption, and it is thrown away.

If you still don't give up, you can cook rice with rice, if the rice is yellow and there is no aroma at all, you can completely discard it.

Hope it helps, hope.
