What is the problem of mildew and spoilage of large and small corn grits What should I do if I need

The cause of moldy spoilage of corn grits can be that it is not dried sufficiently and placed in a humid environment. To preserve corn grits for a long time, they should be kept fully dry and stored in a ventilated, cool, and moisture-proof place.

Here are some specific suggestions:

1.Adequate drying: When making or processing corn grits, make sure that they are completely dry. Moist corn grits are more susceptible to mold and spoilage.

2.Storage environment: When storing corn grits, they should be placed in a ventilated, cool, and moisture-proof place. Avoid placing it on wet ground, which can greatly reduce the risk of mold and spoilage.

3.Regular inspection: During storage, the color, smell, etc. of corn grits should be checked regularly in order to detect possible mold and deterioration in time.

4.Vacuum-packing: If conditions permit, consider vacuum-packing corn grits to keep the air out and prevent it from oxidizing and mold.

5.Low temperature storage: If conditions permit, corn grits can be stored in a low temperature environment, which can also effectively extend its shelf life.

6.Insecticidal treatment: During storage, if insect infestation is found, insecticidal treatment should be carried out to prevent damage to corn grits by insect pests.

In short, to preserve corn grits for a long time, it needs to be fully dried, maintain a ventilated, cool, and moisture-proof storage environment, check regularly, and take appropriate storage measures, such as vacuum packaging or low-temperature storage, etc.

If you want to preserve corn ballast for a long time, you should turn it frequently for a long time, and do not put it in a damp place.

Corn grits are moldy and spoiled, don't eat it again, this thing is not expensive now, don't be reluctant to eat an accident, it will not melt too much. Besides, now in supermarkets in various cities, corn grits can be bought at any time, and they can be used at any time, so there is no need to store them for a long time!

Large and small corn. What's the matter with the broken flowers without braids, they need to be stored for a long time, what should I do? Then you can put more preservative, so that he doesn't run out.

If the corn is moldy, it can be mixed into normal corn according to a certain proportion, or the moldy corn can be crushed, and then soaked and cleaned with water, or the mold in the corn can be adsorbed out by using minerals such as zeolite, bentonite, and activated carbon.

For mildly moldy corn, the following treatments should be carried out:

1. Dilution. A small amount of mildly moldy corn is gradually incorporated into normal corn in multiple batches.

2. Washing. Crush the mildew corn, add 3-4 times of water, stir and soak, stir and change the water twice a day until the soaked water turns from brown to colorless, and use it as soon as possible after washing.

3. Degermal detoxification.

The toxins of moldy corn are mainly concentrated in the germ part of corn. First, the corn is ground into small particles, add 5-6 times of water, and then stir, the germ part of the fragments float on the water surface because of the light density, take it out or pour it out with the water, and so on several times, you can achieve the purpose of degermination and detoxification.

Fourth, physical adsorption.

Minerals that can adsorb and trap mycotoxin molecules - aluminum silicate, zeolite, bentonite, activated carbon, diatomaceous earth, etc., or bovine serum albumin, esterified manna oligosaccharides, etc.

5. Chemical treatment.

Lime water, soda, hydrogen peroxide treatment or supplementation with synthetic salt laxatives such as magnesium sulfate.

6. Supplement nutrients.

Supplementing with adequate VA, VD, VE, VK, folic acid, organic selenium, methionine, etc. to alleviate the toxic effect, or using organic acid additives, probiotic products such as lactic acid bacteria, yeast, etc. can also help alleviate the toxicity of mycotoxins, and some enzyme preparations are also conducive to alleviating the harm of mycotoxins.

Handling of heavily contaminated corn:

Corn with more serious mildew should be purchased centrally, stored in special warehouses, and sent to the quality inspection agency for testing in a timely manner, and the corn with excessive toxin content can only be sold as industrial grain for directional sales, and shall not be used for grain and feed processing, and must be destroyed and not used if the mildew is serious.

There is too much corn harvested in the countryside, and it can't be sold out for a while, and it accidentally becomes moldy, what should I do at this time?

Let's teach you some ways not to lose too much, first of all, separate the moldy from the good, and then distinguish the severely moldy from the slightly mildewed corn.

Method steps.

Good corn is taken and sold.

Dispose of mildewy corn as soon as possible.

A simple physical way to remove mold is to wash it and dry it in the sun. It is used to sell feed to feed mills for livestock.

Complex and laborious methods include: oxidant removal, microbial removal, Chinese herbal removal, etc.

Personally, I feel that it is too laborious, and in the long run, I can buy an intelligent grain sterilization and rubbing mold removal machine, which is convenient and trouble-free, and can also be rented to others when not in use, which is a good income, even if it is lent to others for free, you can also earn personal favors.

Deal with severe mildew.

After ripening, it can be used as fertilizer and can be used as a nutrient for future crops.

Precautions. I heard that if you sell moldy corn to people to eat, you will be hit by five thunderbolts, and you will have no children and grandchildren.

It must be inedible, the grain is moldy, and the toxins are very large. If there is a farmer, you can boil it into fertilizer, if there is no vegetable in the city, the farmer can only throw it away.

People can't eat it, they can wash it, dry it, and feed it.

Don't want moldy food, throw it away.

If the corn becomes moldy, you can expose it to the sun.

Corn moldy situation, absolutely not edible, moldy corn contains a toxin called aflatoxin, is a carcinogenic toxin, the vitality is very strong, 100 degrees of high temperature is difficult to effectively kill it, and resistant to low temperature and cold, once people eat to increase the carcinogenic mechanism and risk.

Try not to eat it, it's not suitable to eat a bad stomach. *Even if you are reluctant to throw it away, you should warm it up and eat it sparingly.

Corn and other grains, once moldy, do not eat again, because the grain is moldy, no matter how light or heavy will produce a bacterium called aflatoxin, aflatoxin is extremely toxic, even if you eat a small amount of food containing aflatoxin, it will cause harm to the human body, and over time it will cause major diseases such as liver cancer. Therefore, when the grain is moldy, we must not be stingy with this bit of food, so as not to bring great hidden dangers to the human body.

As the temperature rises, corn is susceptible to mildew, so you must pay attention to these storage methods!

New countryside in the north.

The rising temperature has become an obstacle for many farmers who have not yet sold their grain, and a little carelessness will make their corn mildew, reduce the quality, and sell at a lower price.

What causes corn mildew?

1.The embryo of corn is large and breathes vigorously.

The embryo of maize is the largest of cereals in the cerealaceae family, accounting for almost 1 3 of the whole grain volume. The corn germ tissue is loose, the fat content is high, and it contains more soluble sugar and protein, so the corn germ has strong hygroscopicity, vigorous respiration, and is easy to rancidity.

2.The embryo has a large amount of bacteria and is prone to mildew.

It has been determined that after a period of storage, the amount of bacteria carried by corn is much higher than that of other cereal grains. After the embryo absorbs moisture, mildew begins at a suitable temperature. At present, the general corn can only be sold to the grain depot after drying, and the water content drops below the safe water, and the current drying capacity is limited, and most farmers can only rely on natural dehydration and air drying, which also increases the chance of mildew.

To store corn, these you should pay attention to:

When the moisture content of corn exceeds 20% and the grain temperature reaches 10, there will be the possibility of mildew in the embryo. After the early spring, the temperature rises, and the moisture in the corn should be reduced in time through ventilation, drying, etc., so as to carry out long-term storage.

For most areas of our province, the temperature has risen relatively quickly in the past two days, and the water content is relatively high. Therefore, the "ground grain" should find the right time to act quickly, the risk of mildew is increasing day by day, once a large area grows hair, it will be completely destroyed. If you are not in a hurry to sell, hurry up and find a way to store it properly.

It is best to dry the corn and store it to prevent mildew

Hello, mildew in corn is closely related to moisture content and temperature. When the moisture content of corn is reached, Aspergillus (such as Aspergillus flavus) can grow; When the water content is reached, Penicillium can grow. The moisture content of corn is in the range of 14%-40%, and the higher the moisture, the stronger the respiration, and the reproduction of microorganisms and pests is accelerated.

When the moisture content of corn kernels is 20%-35%, the air humidity is greater than 85, and the temperature is higher than 25, corn is most likely to mildew. When the moisture content of corn is less than 14%, the feed temperature does not exceed 25, or the moisture content is within 13% and the temperature does not exceed 30, it can be safe to spend summer.

Removal of impurities corn harvest often contains more impurities such as unripe grains, broken grains, bran crumbs and cob fragments, strong hygroscopicity, large respiration, more bacteria, smaller pores, easy to accumulate damp heat to cause heat and mold and insect pests, so corn must be sieved after harvest to remove impurities and then stored in storage to ensure safe storage of grain.

Dry and cool safe storage corn must control the moisture and temperature conditions, according to practice, corn water, temperature about 35, generally can be stored safely.

After harvesting, corn should be fully exposed to the sun or dried to meet the safe moisture standard. Attention should be paid to ventilation and moisture dissipation during storage, and the newly harvested corn should be kept in dry and low humidity conditions to ensure safety. The "double low" storage was adopted, and the storage effect of low humidity and closed input, low dose aluminum phosphide flakes and natural oxygen reduction was good.

The use of plastic film to control pests and diseases can not only prevent insects, but also have a good effect of moisture and poison prevention. The corn that has been insects can be controlled by sieving or drug fumigation. Corn grains are large, the body of general pests is small, and the effect of using 6-hole sieve to remove insects can reach more than 80%.

The cost of fumigation with phosphine agent is low, and the insecticide is relatively thorough. In the northern region, the cold and low temperature treatment in winter is mostly used to reduce the grain temperature to below 0 and seal it while it is cold, which has a good effect on the control of beetles and moth larvae.

Discard and do not eat.

In moldy corn, peanuts and nuts will contain a large amount of aflatoxin, aflatoxin is a first-class carcinogen, the main harm is the liver, the liver in a chronic poisoning state for a long time will lead to liver cirrhosis or liver cancer, in life must be carefully identified.

In addition, there are some damaged or yellow-green substances on the surface of the corn, and it is not edible.

Other moldy and inedible foods:

1. A large amount of arthropodium will appear on moldy sugarcane, which will produce neurotoxins, which directly damage people's digestive system and central nervous system, and may cause poisoning after eating. Patients with mild poisoning may experience nausea, vomiting, diarrhea, abdominal pain, and even black stools.

Severe patients will have neurological poisoning, such as dizziness, headache, convulsions and difficulty swallowing, etc., if not received in time**, they may become vegetative, and even lead to death. The moldy cane skin does not have any luster and is relatively soft in texture, which will smell noticeably musty.

2. When the fruit first starts to rot, a large number of bacteria will breed, resulting in patulin. Chactulin is highly toxic to the body, damages the urinary and nervous systems, and even causes cancer.

If the corn is moldy, you can't eat it, so throw it away.

The grain storage method is to store the threshed corn in the warehouse. This method has a high utilization rate of warehouse capacity, such as good warehouse airtightness, and seeds are in low temperature and dry conditions, which can be stored for a long time without affecting the vitality.

The key points of the grain storage method are: reduce the moisture of the seeds for dry storage: strictly control the moisture of the seeds in storage, strictly prevent the seeds from absorbing temperature and moisture after storage, and the moisture content of the seeds can not exceed 13% under general warehouse conditions;

Low temperature sealing: corn seeds with water content reduced to the safety standard, choose cold weather warehousing or cold weather ventilation and cooling methods, after cooling, pile up the surface cover mat or sack, and then cover clean and insect-free soybean stalks, wheat bran, dry sand, cotton blankets and other caps and store them in a closed and closed storage, which can keep the seeds in a low temperature state for a long time and reduce the harm of insects and mildew;

Ventilation storage: due to the drought in winter and the lack of rain in the northern region, some places use hoarding and open-air bulk storage, and still use ventilation to reduce the moisture of seeds, and then store them in the warehouse after precipitation. However, care must be taken to prevent frost damage to seeds.

The advantages of the ear-storing method are: the nutrients in the cob can continue to be transported to the grains of the newly harvested corn ears, so that the seeds can reach full maturity, and the post-ripening can continue on the ears; The porosity between the ears and the ears is large, which is convenient for air circulation, and the moisture in the pile is easier to dissipate, and the high-moisture corn is not dry, after a winter of natural aeration, the moisture can be reduced to the safe moisture, and it can be threshed in the spring of the second year, and then stored in a closed manner;

The grains are tightly grained on the cob, and there is a tough peel, which can play a certain protective role, except for the small quantum particles at both ends of the ear can be moldy or eroded by insects, the vitality of the middle part of the seeds is not affected, so this part of the seeds is often used as sowing material in production.
