Can you still eat soybeans that have been stored for five years?

Can not be eaten, in general, the shelf life of soybeans.

for one to two years. The best way to identify whether soybeans can be eaten: the first is to look at it to see if there are insects, insects indicate that soybeans are stored for a long time, to see whether its cortex is seriously cracked, if there are many cracks in the skin like fried soybeans, it means that soybeans are stored for a long time.

The second is to smell, grab a handful of soybeans and smell them, if there is a musty smell, it means that it has been stored for a long time. The above kinds of soybeans are not edible.

After five years of soybean storage, if it is properly stored and often dried in the sun, it not only kills mold with ultraviolet rays, but also reduces the water content, and consistently maintains a safe water content, and the quality of soybeans has not deteriorated, so it is completely safe to eat. In the countryside or at home, the way to test whether soybeans are edible is to look at them, smell them and soak them.

At first glance, it is to see whether the skin of soybeans is shiny, whether there is moisture, whether there is mildew, and the shiny ones can be eaten. Second, the dried soybeans smell musty. After soaking in water, there is no fishy smell of fresh soybeans, if so, you can eat it; Then rub it gently with your hands, separate the two petals but not easy to crumb, and can be eaten; If the soybeans are gently kneaded and turn into a soft matter like crumbs, they are moldy and spoiled and cannot be eaten. ‍‍

Can soybeans that have been stored for five years still be edible? My opinion is that as long as the storage conditions are up to standard and the quality of the soybeans has not changed, they can be eaten. Otherwise, if there is a phenomenon such as color discoloration, mildew, insect column, etc., it is resolutely inedible.

Soybeans are not a particularly expensive food, and even if the quality of soybeans that have been stored for five years has not changed, it is better not to eat them again, and in any case, they must not taste as good as fresh soybeans.

We didn't keep the soybeans for five years, but we did store them for three years, and we put them in those big mineral water bottles, and sealed them with lids. Perhaps because the plastic bottle is sealed, the beans have not spoiled at all. Some people say that soybeans should be dried before eating, but we don't have anyone here to dry soybeans, and soybeans are not allowed to be dried like rice.

Of course, if you don't store it properly, you must not eat soybeans that are moldy and spoiled, because spoiled soybeans and peanuts have Aspergillus flavus, and eating them will be poisoned. However, these spoiled soybeans should not be thrown away, they can be fried and fed to vegetables and crops, which is a good organic fertilizer. ‍‍

Whether soybeans can be eaten or not, the key is whether they are tidal and mildew. Soybeans are stored for five years, if they have been tidal for a long time, and there is no mildew, such soybeans should never be eaten; If it has been tidal and mildew, it is also inedible. Because soybean moisture can not be mildewed, it means that the inner surface of soybean contains anti-mildew and anti-mildew drugs, such as formaldehyde, sulfide, etc., which are commonly used anti-mildew agents and are harmful to the human body; If the soybean is moldy after the tide, such as Aspergillus flavus, green mold, Penicillium and other molds are seriously polluted, it is inedible. ‍‍

Soybeans that have been stored for five years cannot be eaten, which will spoil the stomach.

Soybeans that have been stored for five years can still be eaten if they do not survive and do not grow.

If it is a domestic local soybean, let alone 5 years, it will be almost eaten by the bean worms if the medicine is not released for half a year, and the imported genetically modified soybeans are different: disease and insect resistance, drought resistance, and there may be no problem for a few years.

Soybeans with good storage conditions can be eaten, and the soybeans in the national grain reserve will be stored for a long time. Soybeans stored by themselves, due to limited storage conditions, often occur damp change, mildew, oil, insect and other phenomena, if the time is too long, if you are not sure whether it has deteriorated, it is best not to eat.

I think it's edible if it's stored properly, without moth-eaten skin, without mildew, without cracked skin, and looking shiny. Or soybeans that have been stored for five years must be carefully checked for poison and mildew. Soybeans containing poisonous mildew are inedible to humans and animals. ‍‍

If you put it for five years, you can eat it as long as you don't have worms, and it is estimated that it won't last for five years. I didn't read the poison when I gave birth to insects.

The soybeans that our family harvested in November 18 did not dare to eat in the second half of 19. It is also in a sealed plastic bottle. There are a few cracked inside, and the top has a blackened appearance, and the other uncracked whole bottles are fine.

If you keep it, you can eat it for a hundred years.

If you can still give birth to good sprouts, it is good, and if you can't give birth to sprouts, it is not good.

5 years. Soybeans are not easy to grow insects after drying, and they are stored in a ventilated, dry and sealed environment for a long time. Soybeans are leguminous soybeans native to China and cultivated all over the world.

The plant is 30 90 cm high, the stem is stout, erect, densely covered with long brown bristles, the leaves are usually 3 leaflets, the leaves are veined, covered with yellow pubescence, and the petiole is 2 20 cm long. <

5 years. Soybeans are not easy to grow insects after drying, and they are stored in a ventilated, dry and sealed environment for a long time.

Soybeans are leguminous soybeans native to China and cultivated all over the world. The plant is 30 90 cm high, the stem is stout, erect, densely covered with long brown bristles, the leaves are usually 3 leaflets, the leaves are veined, covered with yellow pubescence, and the petiole is 2 20 cm long. peduncle usually has 5 to 8 sessile, tightly packed flowers, calyx lanceolate, flowers purple, lavender or white; pods hypertrophied, slightly curved, drooping, yellowish-green, densely covered with long-brownish-yellow hairs; Seeds 2 5, oval, nearly spherical.

Depending on the situation, the shelf life of soybeans is generally two to three years, if the environment is properly placed, it is better, if the soybeans are not discolored, deteriorated, should be edible, of course, it is not recommended to eat soybeans for too long, it is best to eat fresh, healthy, if you are really not at ease, don't eat it.

Soybeans are nutritionally comprehensive, and soybeans are rich in soybeans, in which the protein content is 2 times higher than that of pork and twice the content of eggs. The protein content is not only high, but also ***. The amino acid composition of soybean protein is similar to that of animal protein, and the amino acids are relatively close to the ratio required by the human body, so it is easy to be digested and absorbed.

If soybeans are eaten with meat and eggs, their nutrition can be compared with the nutrition of eggs and milk, and even exceed the nutrition of eggs and milk.

As long as the soybeans have not gone bad, they can be eaten.

Soybeans can not be eaten after expiration, food deterioration is a continuous gradual process, not to say the expiration date, food suddenly becomes poison, but beyond the scope of the manufacturer's commitment and guarantee, there is a risk in eating at this time. Try to eat food before the expiration date to avoid the risk of "just in case" after the expiration date. It is generally not recommended to consume those that have exceeded the expiration date.

In addition, the specific situation is analyzed on a case-by-case basis.

Soybean has strong hygroscopicity, easy to mold, soybean seed coat is thin, germination hole is large, and the moisture absorption capacity is stronger than that of wheat and corn. After the soybean absorbs moisture and returns to moisture, the volume expands and is very easy to mold. At first, the bean grains are soft, the seed coat is gray, white, and there is a slight peculiar smell, and then the bean grains are swollen and deformed, the umbilicus is red, and the broken grains appear colonies, and the quality deteriorates sharply.

Storage method

Strictly control the storage moisture, and the long-term storage moisture of soybeans should not exceed 12%. After the soybeans are harvested, they are thoroughly dried on the pods before threshing. Soybeans with high moisture content after storage can be treated by sun exposure, but they can only be put into the warehouse after being cooled.

Timely ventilation to dissipate heat and moisture. The moisture between the newly stored soybean grains is uneven, coupled with the post-ripening effect of soybeans, the damp heat in the pile is easy to accumulate, causing heat and mildew, so it is necessary to ventilate in time to dissipate heat and moisture.

Closed storage at low temperature. After entering the winter, ventilation and cooling should be strengthened, and the gland or plastic film should be used for closed storage before the spring is warm, so that it can generally be safely spent in summer.

Soybeans can still be eaten after almost ten years, soybeans are nutritious, the shelf life of soybeans is two to three years, if the environment is properly placed, it is better, if the soybeans are not discolored, spoiled, should be edible, but still eat fresh soybeans.

Soybean is an annual herb of the genus Dicotyledons, Fabaceae, and Soybean, with a height of 30-90 cm. The stems are stout, erect, densely covered with long brown bristles.
