What should I do if rice is prone to insects and mold? Is there any way to keep it from breaking?

Rice is particularly prone to mold and insects in summer, and today I will share with you a trick for preserving rice, which will not be bad for a few years, which is very practical.

You can put the rice in a ventilated and cool place, spread it on a clean ground, and then carefully pick and throw away the rice with insect spots and mold; If you want the rice not to spoil, you only need to put a few garlic cloves in the rice and cover the bag tightly, because the special smell of garlic can effectively prevent small insects from getting close to the rice.

Rice is easy to grow insects, you can put some peppercorns in it to achieve the effect of insect repellent, if it is moldy, try to put it in a dry place, avoid moisture, and the way to prevent rice from going bad is not to put it for too long, buy less every time you buy it, and buy it after eating.

You can freeze the rice in the freezer compartment of the refrigerator first, and then take it out a few days later and put it in a closed bottle, so that it is not easy to grow insects and is not easy to get damp and moldy.

Three ways: sealed, garlic, dried kelp;

Rice can be kept for a long time by drying it in the sun and then in a dry mineral water bottle.

Putting dried kombu in a rice jar can effectively prevent rice mildew and rice worms. But dried kelp needs to be taken out and dried once a week.

Put the garlic into a gauze bag, put it in the middle of the rice bowl, seal the bag, and then put it in a dry, cool and ventilated place. It can prevent the rice from getting damp and insects.

Lose. If the rice is moldy, it cannot be eaten by humans, because the moldy rice will contain a large amount of aflatoxin, and if humans eat moldy rice, it will cause diarrhea and liver cancer. Then moldy rice cannot be eaten by humans, and in addition to throwing away the rice, it can also be used as feed for raising poultry, such as feeding chickens and ducks.

Precautions for rice purchase.

The aging phenomenon of rice is 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 the white groove is old rice, and the more the amount of fiber, the more old the rice. At the same time, pick up the rice and smell the smell to see if the rubber imitation is normal, if there is a moldy smell, it means that it is old rice.

In addition, if 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.

Look at the label: When buying rice, you should also pay attention to what is marked on the package. For example, whether the product name, net content, name and address of the manufacturer and distribution enterprise, production date and shelf life, quality grade, product standard number, special labeling content are marked on the package, etc.

<> "Easy Prevention of Rice Insects and Mildew.

1. Zanthoxylum pepper insect control method.

Wrap some peppercorns with a few pieces of gauze, put them in a container for rice, place them in different positions at the top, middle and bottom, and then cover the container tightly. If you are using a bag to fill the rice, you can put the bag directly into the boiled pepper water to soak it and dry it, and then fill the rice to prevent insects.

2. Liquor insect control method.

Because the volatile ethanol in liquor has the effect of killing insects and sterilization, it can prevent rice insects. Put a clean bottle of liquor in the container where the rice is stored, the mouth of the bottle is higher than the rice noodles, without a lid, and then the container is tightly covered to prevent insects.

3. Kelp insect control method.

Because dried kelp has a strong ability to absorb moisture, it can play a role in killing insects and inhibiting mold. Put some dried kelp in the rice, the ratio of rice to kelp is about 100:1, take it out every 10 days or so, dry it, and then put it in a rice jar.

This method can be used repeatedly and can effectively prevent rice mildew and insects.

4. Lime insect control method.

Spread some quicklime on the bottom of the rice container, spread some plastic cloth on the top, and then enlarge the rice, and cover the container tightly to prevent insects.

5. Garlic insect control method.

Scatter a few cloves of garlic in the container where the rice is stored, and cover the container tightly, which can also have the effect of preventing insects.

6. Bottled insect control method.

You can put the bagged rice in a drink bottle separately, and it can be stored for a long time without insects.

Smelling a foul smell is a sign of fever and mildew.

In the process of early heating and mildew of rice, the loss of rice quality is not obvious, and timely treatment will not affect the consumption of rice. However, when cooking such rice, the skin must be removed, washed several times with clean water, and the floating matter and rice bran in the water must be skimmed out, which reduces the mycotoxin content in the rice.

If the rice is accidentally wet and damp, the rice will be bran off, and the rice grains will look rough and unclean. Rice will also "eye-catching" and "gluten-rising", rice "eye-catching" is due to the fact that the tissue of the rice embryo is relatively soft, and there is more protein and fat in this part, and mold will invade from here first, causing the embryo to change color.

"Gluten" means that the grooves on the sides and back of the rice grains appear white, and then turn grayish-white, and the color of the rice is dark. If the rice is moldy, hold the rice tightly with your hands to form a ball. If the rice has a phenomenon such as eye-catching and gluten, the degree of mold of the rice is already obvious.

At this time, it is necessary to spread out and ventilate the rice, and dispose of it in time to prevent further deterioration.

Improper storage of rice can easily make the rice moldy. The surface of moldy rice is gray and tarnishing; At this time, the rice will produce aflatoxin, which is very toxic and can cause cancer if eaten. It is possible to prevent the rice from becoming moldy and insect-proofing by lowering the temperature, lowering the humidity, and the kelp insect control method.

What to do with rice worms

After long-term storage, due to the influence of temperature and moisture, various changes will occur in the starch, fat and protein in the rice, which will make the rice lose its original color, aroma and taste, and the nutrients and eating quality will decline, and even insects will be born. After the rice is wormed, three methods can be used: shady sieve worms, frozen insecticide, and organic acid fumigation.

1. Cool sieve worms.

After the rice is insect, people often like to expose the rice to the sun, which not only fails to achieve the purpose of killing the rice worms, but will be counterproductive, because after two or three days, the rice worms in the rice will increase unabated, and the exposed rice will affect the taste due to the loss of moisture. The correct way to do this is to put the raw worm rice in a cool and ventilated place, let the worms crawl out slowly, and then sift it again.

2. Freezing insecticide.

If there is not a lot of rice with insects, you can put the rice with insects in a plastic bag, tie the bag tightly, put it in the freezer compartment of the refrigerator, and take it out after 48 hours to kill the moths in the rice.

3. Organic acid fumigation.

There are many insects in rice, and phosphorus zinc plus organic acid can also be used to fumigate. The specific method is as follows: in the veranda or idle room, put the rice bag of raw insects together in a well-sealed plastic bag, that is, the fumigation bag, and then put a cup or wan in the fumigation bag, and put 50 grams of vinegar in it; If the grain does not exceed 500 kg, wrap one gram of zinc phosphide in paper and put it into a cup or bowl filled with vinegar, without stirring, and immediately seal the mouth of the fumigation bag.

Seal for 5-10 days to kill all the pests inside. After that, disperse the gas for 2-3 days, take out the vinegar and water and sort out the residue.

1. Store in an appropriate amount according to the season. During the year, depending on the season, you can adjust the amount of rice at home. Under normal circumstances, the weather temperature in summer is high, the air humidity is high, the rice is very susceptible to moisture and mold, and it is difficult to store, so it should be stored less, and it is best to buy and eat at any time.

In autumn and winter, the temperature is low and the climate is dry, and the rice is not easy to be affected by the environment, and its edible quality can be stored in moderation. 2. Timely ventilation, moisture-proof and heat insulation. Whether it is a supermarket, vegetable farm or family, the preservation of rice in summer should pay attention to moisture-proof and heat insulation, and store it in a cool, dry and easily ventilated place as much as possible.

Specifically, it is necessary to pay attention to three aspects: pay attention to moisture-proof and should not be mixed. Because rice has strong moisture absorption, it should be moisture-proof and should not be mixed.

For example, rice should not be placed against a wall and should usually be placed on a backing plate to prevent moisture; Rice should not be stored at the same time as fish, meat, vegetables and other foods with high moisture, otherwise the rice absorbs water and is prone to mildew or insects. Pay attention to heat insulation and keep away from heat sources. In a high-temperature environment, rice is prone to heat and mildew, so attention should be paid to heat insulation and stay away from heat sources.

For example, rice should not be stored in the kitchen, because the high temperature and humidity in the kitchen have a great impact on the quality of rice; Rice should not be placed next to the stove, because it is too close to the heat source, the rice will heat up and cause quality changes. Pay attention to dry in the shade and avoid exposure to the sun. If the rice is wet, it should be spread out in a cool and ventilated place to dry and blow thoroughly, and should not be exposed to the sun.

Because exposure to the sun will quickly lose moisture, some particles will be broken, resulting in a great reduction in the quality of eating, if put back into a humid environment, it is more likely to be damp, mildew, and insects. 3. Natural hypoxia, scientific insect control. During the season of high temperature and humidity, there are many historical experiences in preventing rice insects.

For example, mix a few heads of dried garlic in a rice bag (garlic food); Or take pepper or fennel, wrap it into a number of gauze bags, put it in a rice bag and seal it. However, after using these methods for a long time, the rice will retain a certain smell and affect the consumption, and the pests will also become resistant to a certain odor, which still cannot achieve the desired effect.

So, how can you prevent insects without affecting your consumption? According to grain preservation experts, it is difficult for insect eggs to develop into larvae in the case of low oxygen or lack of oxygen, so family rice storage can be sealed with plastic film hypoxia, and this natural deoxygenation method is used to preserve rice, which can not only achieve the effect of insect control, but also will not affect the eating quality of rice.

The following points should be paid attention to in the preservation of rice: 1. Rice should not be stored at the same time as fish, meat, vegetables and other foods with high moisture, otherwise the rice will absorb water and lead to mildew. 2. Rice should not be stored in the kitchen; Due to the high temperature of the kitchen; High humidity has a great impact on the quality of rice.

3. Rice should not be placed against the wall, usually placed on the backing board, the purpose of this is also to prevent rice mildew or insects. 4. Rice should not be placed next to the stove. If you are too close to a heat source, the rice will heat up and cause a change in quality.

Millet tips for preserving rice: This method makes your rice not grow worms for a year, 1: We use a dried kelp, put the dried kelp in the rice, the dried kelp has a layer of white frost on it, which is alginate, which can keep the rice dry and has the effect of hygroscopicity, so that the rice will be stored for a longer time.

Divide into small packages and store in the freezer compartment of the refrigerator.

It's best to take this out often.

Ren Shuncheng, associate professor of the College of Cereals, Oils and Foodstuffs, Henan University of Technology.

Many people are accustomed to buying a bag of rice and eating it slowly, if it is not stored properly, the rice will become moldy. Ms. Zhu, who lives in Zhengzhou's Jinshui District, encountered such a problem, her family bought a bag of rice in the summer, but because she usually doesn't cook much, the rice has not yet been eaten. A few days ago, she found that the rice had a musty smell and the color was dark, but there was no long hair, and the musty smell had not dissipated after steaming.

Due to the loss of chaff and seed coat, the endosperm is all exposed, and it is susceptible to mildew due to the influence of external moisture, heat and other factors. The mildew of rice is mainly caused by Penicillium and Aspergillus in the fungus, and their secondary metabolites have serious damage to the liver and even lead to human poisoning.

The main characteristics of mildew in rice are:

1.Dark color: The color of rice grains is dark and dull.

2.Dampness: The surface of the rice grain is slightly moist, commonly known as "sweating".

3.Softness: The moisture of the rice grains increases, the hardness decreases, and the crisp sound decreases when rubbed by hand or with teeth.

4.Fluffing: The rice grains are moist, and the unfinished bran skin on the rice grains floats up, making them look rough and unclean.

5.Ribbing: The grooves on the sides and back of the rice grains are white, and continue to develop into grayish-white, like rib lines.

6.Eye-catching: Because the embryonic tissue of rice is loose, rich in protein and fat, mold erodes first, causing the embryo to change color, commonly known as "eye-catching".

7.Peculiar smell: The original aroma of rice is weakened or disappears, and a sour taste of bran appears.

In the early stage, the quality of rice does not change much, and if it is processed in time, it will not affect the consumption. Before cooking, you can scrub with water several times, pour out the floating matter and rice bran in the water, reduce the content of mycotoxins in rice, and mix most of the good rice at the same time to dilute mycotoxins and reduce the harm to the body.

When the rice grains appear tendoned, the grooves form white lines, the rice embryo is seriously discolored, and it smells obvious musty, it means that the rice has entered the second stage of mildew, and the rice at this time is inedible.

The main damage caused by moldy rice to the human body is the toxins produced by mold, which are generally relatively stable and not easy to destroy, and are difficult to eliminate even if they are exposed to sunlight, so if the degree of mildew is serious, it should be resolutely not eaten.

Hello. Ate moldy rice once in a while. Does not cause cancer.

If you eat it regularly, it can cause cancer. Because the moldy rice has aflatoxin in it. Aflatoxin is a recognized carcinogen.

Now living conditions have improved. Moldy rice is no longer edible. Throw it away.
