How long can seed fava beans be frozen

Do not freeze, the task of seed storage is to ensure the quality of seeds, prolong the life and use of seeds.

Seed storage focuses on preventing browning and broad bean elephant damage. The storage conditions require the relative humidity of the warehouse to be 65%, cool, and the moisture content of the seeds is below.

1. Storage characteristics of broad bean seeds.

Among crops, broad beans are a large seed with rich protein and a small amount of fat, and the seed coat is relatively tough. As long as the moisture is reduced to below the safe water content, the stability during storage is relatively good, there is rarely heat and mildew, and there will be no rancidity and deterioration, the main problem is how to prevent the harm of broad bean elephant and seed discoloration.

The broad beans that are harmed by the broad bean elephant have a decrease in germination rate, deterioration in quality, increased loss, and when the insect infestation is serious, it can also cause broad bean fever. The seed discoloration is due to the fact that the skin layer of broad bean contains polyphenol oxidizing substances and tyrosine, etc., under the combined action of air, moisture and temperature, the activity of oxidase is enhanced, and the oxidation reaction is accelerated, so that the skin color of broad bean gradually changes from the original green or milky white to brown, dark brown and even reddish-brown or black.

2. Broad bean seed storage technology.

1. Prevent discoloration: As long as the moisture of broad beans is reduced to the following during storage, and daily management is done, adverse changes such as heat and mildew rarely occur. Then use low temperature, drying, airtight, and dark storage methods, which has a good effect on preventing broad beans from changing color.

2. Prevention and control of broad bean elephants: From the perspective of the life history of broad bean elephants, adult oviposition and hatching larvae are carried out in the field, while pupation and adult emergence are completed in the process of broad bean storage. Broad beans are harvested and stored until the end of July, which is the larval stage and pupal stage, and the larvae should be killed when the larvae are very small, and can be fumigated with aluminum phosphide or chloropicrin.

The dose is calculated according to 700kg per cubic meter of broad beans, with 50 60g of chloropicrin or 3 tablets of aluminum phosphide (about equivalent to 4g of chloropicrin per 50kg of broad beans or 1 tablet of aluminum phosphide for 225kg of broad beans), put it in a bean pile and seal it for 5 10 days. The entire fumigation work should be completed before the end of July, and after the fumigation is completed, it should be ventilated in time to prevent the broad beans from changing color.

Of course, it has no effect on the nutrients. In order to preserve the peanuts, many merchants put them in cold storage to prevent them from germinating. But food has a shelf life, don't leave it for too long, it's best to eat it within two or three months, otherwise even if there are no harmful substances, the taste will be different.

Don't put it in the refrigerator, put it in a dry place, don't put it in a cool and damp place, it will rot!

Fava beans can be stored for a day or two, or for more than half a year, or even for a year. How long can it be stored depends on the method of preservation, and the storage time is also different depending on the method, if it is a fresh broad bean, you can put it directly in the refrigerator to preserve, and it can be stored for one to two days.

If the fresh broad beans are peeled, cooled in water, and then sealed and preserved, they can be stored for half a year, and if they are dried into dried silkworm beans, they can be stored for more than a year.

The main value of broad beans

Broad bean is one of the earliest legume crops cultivated by human beings, there are more than 40 countries in the world that grow broad beans, concentrated in the Black Sea and the Mediterranean coast, China has more than 40 cultivars, the output of this century in the 50s ranked first in the world, with an annual output of more than 3 billion senliang kilograms. As a grain mill to make pastries and snacks. When young, it is used as a new vegetable or feed, and the seeds contain protein and starch 43%.

Broad beans are not only an important agricultural product for export, but also have a variety of uses in the farming system—the rotation of legume crops with other crops is conducive to increasing the nitrogen content in the soil, which is an economic income-increasing crop.

Wash the fresh broad beans and put them in a crisper or bag to seal them and store them, and then put them in the freezer layer of the refrigerator to freeze them, which can play a good role in protection. When freezing fava beans, it is necessary to pay attention to the temperature of the frozen layer, because if the freezing temperature is not enough, it will still cause the loss of moisture and taste of fava beans. Generally speaking, broad beans can be stored in a freezer below minus 18 degrees Celsius, and low temperature can well inhibit the activity of various microorganisms or other molds in broad beans, which can prevent broad beans from deteriorating in the case of freezing.

When choosing broad beans, you need to pay attention to that, generally speaking, fresh broad beans should be emerald green, but not the greener the better, some colors are very green, which may be artificially colored; Broad beans are flat, so when buying, try to buy mature large ones, small grains have not grown, and the nutritional value is poor; Also, don't pick fava beans with black spots, which are perishable.

You can put it in the refrigerator to freeze, peel the broad beans out of the beans, boil in a large pot of water with a spoonful of salt, pour in the beans and boil again, skim off the foam. After boiling, pour out the filtered water of the beans, spread them out to cool, divide them in a plastic bag and freeze them in the refrigerator. <

3. Fresh broad beans can be cooked or processed into broad bean products. Broad bean products refer to products made from broad beans as the main raw material through a series of special processing or refining. In general, they also have a correspondingly rich nutritional value of fava beans.

The nutritional content of some fava bean products is even more comprehensive than the fava beans themselves. Traditional broad bean products generally include non-fermented soy products and fermented soy products. Empty mold non-fermented soy products such as tempeh, soybean milk, flour skin, soybean paste, etc., and condiments such as tempeh paste, tempeh paste, soy sauce, sweet sauce, etc., such as Sichuan Pixian bean paste.

Freezer.

Usually buy broad beans are to remove the pods, at this time the main observation of the color of the broad beans, the color of fresh broad beans should be relatively light green, there are signs of blackening is a little deterioration, with pods of broad beans are generally relatively fresh, do not need to work too hard when choosing.

After fresh broad beans are stored for a period of time, the color will slowly darken, to prevent the broad beans from changing color, as long as the broad beans are placed in a low-temperature, dry, and dark environment, that is, the storage temperature is below 5 degrees, and the moisture content is below 11%.

It's the season to eat broad beans, and in a few days the broad beans will be old. If you want to eat fava beans until they are tender, you can put them in the freezer and freeze them until next year. And when the broad beans are a little older, you can peel off the outer layer of the broad beans, scald them with boiling water, put them in the refrigerator to freeze, take them out and fry them in oil, put a little salt, crispy, but delicious.

I'll go back and do it in a few days, hehe.

Generally, it is divided into a freezer room and a refrigerator, and I usually put it in the freezer.

Fresh broad beans can be frozen, which can preserve the taste and nutrients of broad beans to the greatest extent and prolong the shelf life. However, it should be noted that if you want to freeze the broad beans, you need to store them in the freezer of -18, so as to inhibit the growth of microorganisms or active enzymes in the broad beans.

How to preserve fresh fava beans.

Fava beans are a kind of bean food that is more common in our lives, the nutritional value is very high, and it has great benefits to the body after eating, many people will buy a lot when buying broad beans, but they can't eat it all at once, so we need to find a way to preserve it to prevent spoilage.

Fresh broad beans can be put in the refrigerator for freezing, but you need to pay attention to the temperature of the freezer, if the freezing temperature is not enough, it may lead to water loss of broad beans, affecting the taste. When we preserve broad beans, we can place them in a freezer below -18 for preservation, which can well inhibit the growth of micro-empty rock organisms or active enzymes in broad beans and prolong the storage time.

If you want to preserve fresh broad beans, you only need to clean them, dry them and seal them in a crisper or bag, then put them in the freezer and cook them directly when you want to eat them, so that their taste and nutrients can be preserved to the maximum.
