Fresh corn has been put for a long time, there are pits, will fresh corn spoil after soaking in wate

After the corn is picked, if your corn is not dried and refrigerated, then it will maintain a vigorous metabolism and maintain respiration to provide energy.

After picking, it leaves the plant body and cannot produce nutrients on its own, so it has to consume its own stored nutrients, such as sugar and starch.

Therefore, the corn that has just been picked and the corn that has been left for three days have different tastes.

Fresh corn soaked in water for 6 hours may spoil. Generally speaking, fresh corn is not recommended to soak fresh corn for 6 hours, because the moisture and nutrients in fresh corn are not stable, and soaking in water for 6 hours is easy to prepare for early leakage, which will lead to the loss of nutrients in fresh corn and reduce its nutritional value.

Secondly, it is easy to cause spoilage in the case of high temperatures, so it is generally not recommended to soak fresh corn for 6 hours.

Corn is not recommended to be eaten:Fresh corn is generally sweet and flat, contains a lot of water, Lu Rui is sweet to eat, generally does not have a sour taste, if fresh corn tastes sour, then it is likely to have deteriorated, and it is not conducive to human health after eating, so fresh corn has a sour taste is generally not recommended to eat.

Fresh corn is stored in cold storage at 0 5 °C.

Corn preservation method: ear storage method.

Generally, the area with relative humidity lower than 80% is suitable for panicle storage, which has the advantages of following the nutrients in the cob of the newly harvested corn ear can continue to be transported to the kernel, so that the seed can reach full maturity, and can continue to ripen on the ear;

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. When this method is adopted, the corn ears can be braided into braids and hung in a ventilated and rain-sheltered place, or the corn can be hung into a conical shape around the trunk of the tree, and the grass can be draped at the top of the cone to prevent rain, and the ears of corn with the bracts can be piled up in a simple warehouse made of sorghum stalks. The bottom of the simple warehouse should be a certain distance away from the ground to prevent the harm of livestock, poultry and rats.

The harvested fresh corn cobs are immediately transported to the cold storage and pre-cooled within 1 2h.

Air cooling: The temperature is required to be 0 5, the relative humidity is 85% 90%, the air flow rate is 5ms, and the cooling process is completed when the core temperature of the stacked corn cob reaches 5. However, the general storage time should not be too long, and it can be placed in the cold storage and sealed with a plastic sealed bag for 3-5 months.

It depends. Under the condition of the refrigerator, the low temperature conditions of the refrigerator can not only help the fresh corn preserve its freshness, reduce the breeding of bacteria in the fresh corn, but also prolong the preservation time of fresh corn, generally speaking, fresh corn is stored under the refrigerator, and can be stored for about 4-5 days. The nutrients in fresh corn under normal temperature conditions are easy to react with substances in the outside air to produce bacteria or other substances, which is not conducive to the health of the human body after eating, so it is generally recommended to store it for about 2-3 days at room temperature.

Fresh corn preservation:

1. After buying fresh corn, when you get home, you should remove the old skin on the outside, leaving only two or three layers of tender outer skin inside, and the whiskers of the corn should not be removed, let alone cleaned, directly put them in a fresh-keeping bag, sealed, and then stored in the freezer in the refrigerator, so that the shelf life of the stored fresh corn will be very long, and the new corn will not deteriorate until the second year, which provides convenience for people to eat fresh corn at any time;

2. After storing the fresh corn in the refrigerator, you can take it out at any time when eating, if you want to cook fresh corn, you don't need to thaw, put the fresh corn out of the refrigerator after putting water in the pot, boil it over high heat, and then turn to medium heat and cook for fifteen minutes, the fresh corn will be cooked, and the taste and smell of fresh weight when eating is not worse than when it was just listed;

3. Store fresh corn in the refrigerator, take it out and eat it, if you want to process it into corn juice, or fry corn kernels, you must take it out in advance and thaw it, and then you can eat it according to your needs. If you usually like more fresh corn juice, you can also take off the corn kernels directly and store them directly in a fresh-keeping bag when you store fresh corn, which will be much more convenient when you take it out and eat.

Corn deflated after cooking may be because the corn is not fully ripe or the corn has been cooked for too long, and at the same time, cooked corn can also become deflated after being left for a long time. When we buy raw corn in the future, we should try to pick the one that is not soft, and after cooking the corn, we should take it out and soak it in ice water, so as to avoid the above situation.

Sometimes we may encounter fresh corn that is deflated after cooking, and this may be because the corn is not fully ripe or we have been boiling corn for too long.

In addition, the kernels of cooked corn will also deflated slightly after being left for a long time, which may be due to the loss of moisture in the corn, so it will become shriveled.

When we usually buy raw corn, try not to buy corn kernels that are too soft, this kind of corn may become deflated when cooked. At the same time, after we have finished boiling the corn, we can put it in ice water to soak for a while, so that it will not become deflated after a long time.

Fresh corn can not be kept in cold storage at 2 to 8 degrees.

Corn (Latin name: Zea Mays L.).) is an annual herbaceous plant of the genus Maize in the Poaceae family.

Aliases: maize, cob, baogu, baomi, baosu, jade, bud rice, pearl rice, bract, large reed millet, Northeast Liaoning dialect called pearl grains, Chaozhou dialect called barley kernel, Cantonese called corn, Hokkien called panwheat.

Corn is an annual monoecious cross-pollinating plant with tall plants and strong stems, which is an important food crop and forage crop, and is also the highest total crop in the world, second only to rice and wheat in terms of planting area and total yield. Corn has always been known as a longevity food, rich in egg white matter, fat, vitamins, trace elements, fiber, etc., and has great potential for the development of high-nutrition, high-biological functional foods. However, due to its complex heritability and abundant variants, there are shortcomings such as too long cycle, too large coefficient of variation, and affecting the development of offspring or growth in the conventional breeding process, and modern biological breeding differential return technology not only overcomes the above shortcomings and deficiencies, but also improves the breeding speed and quality.

Corn has a sweet taste and can be used in a variety of dishes, such as corn roasting, corn juice, etc., and it is also a major ingredient in industrial alcohol and shochu.

Corn should be stored in cold storage. 2 to 8 degrees is fine and should not be placed in the freezer.
