How do families store food? How families stock up on food

Every year at the turn of spring and summer, the careful storage of grain becomes the "top priority", because if the storage is not good, rice and white flour.

It is very easy to grow insects, especially flour, and it is easy to get wet and agglomerate. How to store food at home - Rice is generally stored in less than August, and there are very few insects, but it is better to buy rice in small packages now, or buy the kind of vacuum-packed rice.

When storing rice, it should be placed in a backlit, ventilated and cool place. Home storage is best placed on the north balcony to avoid sunlight. When storing rice, there should be a moisture barrier, that is, the rice should be padded with wooden planks for storage.

It is best to keep the rice in the rice jar, the rice jar should be washed and dried in advance, and then smoked with paper or wormwood in the rice jar, so that there will be no insect eggs in the rice jar. Put some star anise or Sichuan pepper at the bottom of the rice jar, and then put the rice in, and close the lid of the rice jar tightly after taking the rice.

If there are insects during the storage of rice, do not expose the rice to the sun, put it in a cool and ventilated place, spread it out, and then sieve it before putting it back into the rice tank. Household grain storage - flour There are many varieties of flour now, and family flour should buy non-whole wheat flour, and it is best to choose refined flour.

Whole wheat flour because it contains wheat germ.

Wheat germ contains oil, which is easy to cause flour to be sour and rotten, so if you buy whole wheat flour, then you should store it in the refrigerator. Refined flour is stored in the same way as rice, but attention should be paid to the air permeability of the flour bag to prevent the flour from becoming moldy and damp and clumping.

Generally, refined flour bought at home has an expiration date.

are about 12 months, as long as you keep it away from light and put it in a cool and ventilated place, you can keep it very well. If the flour is found to be clumping, then it should be exposed to the sun, and then use the fine radish to sieve the flour through the radish to remove the clumping part and store it. Household Grain Storage - Families generally buy less grains, but they are also an indispensable and important supplement to regulate taste.

Leftover oil drums or drink bottles from home.

Brush it clean, then put the grains and beans in it, tighten the cap and store it, and generally it will not spoil for a long time.

Rice and flour can also be stored in oil drums or beverage bottles, which is particularly effective for storing grain. In fact, I feel that it is very convenient to buy food now, and it is better to buy it as you eat, so as to reduce unnecessary losses.

Personally, I think that the food stored at home can be put in large beverage bottles, because I often use beverage bottles to fill millet at home, which is not easy to produce insects and is very clean.

It is best not to put the grain in the kitchen, because the kitchen is humid and will cause the quality of the rice to decline, if the rice cannot be eaten for a long time, it is best to freeze it in the refrigerator to avoid insects.

As the main food, grain is generally hoarded at home, so it should be noted that the grain must be placed in a low temperature and dry place when storing, so that the grain will not be damp or eaten by small insects.

Rice and other cereals and legumes should be sealed and stored in a cool and dry place, and when the humidity is heavy, it is necessary to ventilate, and it is best to vacuum the grain that is not eaten often.

Household grain storage is generally placed in a relatively cool place such as a cellar or storeroom, and if the quantity is relatively small, it can be put in the refrigerator to keep it fresh.

Farmers try to stock up on raw grains, such as rice and wheat. Raw grains can be stored for a longer period of time. Flowers survive peanut fruit.

Reserve finished grain. The first is to find a dry place that does not leak and return to moisture, and do not use containers that have stored grain without insecticide. Second, the moisture of the grain should be as dry as possible, generally lower than the safe moisture (most of the grains are i3%) and higher than the binding water of the grain itself.

The third is that the temperature should be as low and uniform as possible, and the temperature should be as constant as possible. Fourth, aluminum phosphide can be used for fumigation and insecticide, and the sealing condition is normal.

1. Conventional storage; Conventional storage in the warehouse, timely ventilation or closed storage storage methods. Generally, when the temperature and humidity are lower than the grain temperature and grain moisture, open the doors and windows for natural ventilation; On the contrary, it is mainly airtight, or the material with loose structure is pressed on the grain to maintain the temperature and humidity of the grain.

2. Low temperature storage; Low-temperature storage uses low temperature to limit the activities of pests and microorganisms, reduce grain respiration, and achieve safe storage. There are 3 ways to learn about low temperatures: 1

Cooling in winter. 2.Mechanical ventilation.

3.Mechanical refrigeration.

3. Controlled atmosphere storage; Under closed conditions, the method of preserving grain with low oxygen (less than 1%), high nitrogen (99%) or high carbon dioxide (more than 40%) gas. Commonly used sealing materials are polyvinyl chloride and plastic film, nylon and polyethylene composite film, etc.

4. Chemical storage; The use of chemical agents to inhibit the life activities of the grain itself and microorganisms can prevent the heating and mildew of the grain and eliminate the pests of stored grain. Commonly used chemical preservatives are propionic acid, sorbic acid, etc.

5. Underground storage; The decrease and increase of grain temperature in underground granaries are very slow, and the low temperature and spring that can be obtained are often very different due to different geographical locations, so the application is limited to a certain extent. For example, in the northern and central regions of China, the underground speaker silos can reach low temperatures of 12 15 and 18 20 respectively; In the south, it is difficult to obtain such ideal storage temperatures.

During the pandemic, storing food for quarantine at home requires both the ability to maintain adequate nutrition and ease of preservation.

The following types of food can be stored:

1. Staple food: rice, noodles, flour, meat (cut into pieces and put in the refrigerator), etc., these are what we eat every day, so we can reserve them according to the number of people in the family.

2. Root ingredients: root foods such as carrots, potatoes, yams, and sweet potatoes are easy to preserve, and the nutrition is extremely high, especially suitable for the elderly and children. The nutrients of rhizomes are very high, satisfying and full, and they will not be bad when they are usually stored in a cool and ventilated place for a few months.

3.Eggs: The shelf life of eggs is almost 40 days to 60 days (under refrigerated conditions), so you can stock up appropriately according to the needs and quantities of your family.

4.All kinds of cabbage: During the epidemic, you can prepare more cabbage at home, and eating fresh cabbage also has the effect of anti-inflammatory and sterilization, especially purple cabbage, which is rich in a variety of vitamins and anthocyanins, which have excellent anti-aging effects and can also prevent cardiovascular and cerebrovascular diseases.

Cabbage is also very easy to store, and it can be kept in a cool place for several months.

5. Milk: Milk is also an indispensable food for daily life, milk is rich in protein and calcium and other nutrients, a glass of pure milk every day is beneficial to the body's reputation and health, and can also enhance the body's immunity. Choosing pure milk with a fresh date, it is not a problem to eat it for several months at room temperature after the packaged date.

If you don't go out in home isolation, you can prepare more pure milk.
