1. The importance of rice preservation

Rice, as a staple food, occupies a vital place in our daily lives. Not only is it a great source of energy for us, but it is also rich in nutrients such as carbohydrates, proteins, vitamins, and minerals. Whether it is boiled into rice, boiled into porridge, or made into a variety of delicacies, rice is loved by people.
However, improper storage of rice is prone to insects and mold, which will not only affect the edible quality of rice, but also cause food waste. According to statistics, a large amount of rice is wasted globally every year due to improper storage. When rice insects become moldy, they may produce mycotoxins, which pose a potential threat to human health. For example, long-term consumption of moldy rice may lead to food poisoning and even serious diseases such as liver cancer.
In addition, improper storage of rice can also affect its taste and nutritional value. Spoiled rice tastes worse and nutrients are gradually lost. Therefore, proper preservation of rice is essential to keep our diet safe and healthy.
We should pay attention to the preservation of rice and take effective measures to prevent rice from becoming insects and mold. For example, natural insect repellents such as Sichuan peppercorns, star anise, dried kelp, etc., can be used, or rice can be stored in airtight containers such as oil drums, drink bottles, etc. At the same time, pay attention to the storage environment of the rice and avoid placing the rice in a humid, high-temperature, and direct sunlight place. Only by properly preserving rice can we ensure that we can enjoy delicious and nutritious rice at all times.

How to preserve rice?

2. Suitable environmental conditions for preservation

(1) Temperature and humidity requirements
The suitable temperature for rice storage is around 15°C, and the relative humidity is controlled between 60%-65%. Under such environmental conditions, rice can maintain good quality and is not prone to insects. When the temperature is too high or the humidity is too high, rice is susceptible to insect infestation. For example, when the ambient temperature reaches 20°C - 40°C and the humidity reaches 65° - 95°, the eggs in the rice may hatch and begin to reproduce in just one week. Especially in summer, the high temperature and humidity environment will greatly increase the risk of rice insects. At a temperature of around 15°C and a relative humidity of 60%-65%, the respiration and transpiration of rice will be weakened, and its taste and nutritional value can be better maintained.

(2) Ventilation, dryness and avoid direct sunlight
The rice should be placed in a ventilated and dry place, good ventilation can reduce the ambient humidity and reduce the possibility of the rice getting wet. At the same time, be sure to avoid direct sunlight, which can cause serious damage to the rice. Rice contains a lot of nutrients, and exposure to the sun will cause the rice to lose most of its moisture, causing the skin of the rice grains to crack and become broken rice, which will not only lose some of its nutrients, but also make the taste of the rice worse. According to the data, rice after exposure to the sun has a large swelling when cooking, and the viscosity is small and there is no fragrance. From a botanical point of view, rice can not withstand the scorching sun exposure, drying rice will affect the quality of rice, the more intense the exposure, the worse the quality, no matter what you do to cook rice and porridge, it is not good, or even completely useless. Therefore, in order to maintain the quality of rice, the rice should be kept in a ventilated and dry place away from direct sunlight.

3. Practical preservation methods

(1) Sealed preservation method
Leftover canned food bottles or large mineral water bottles can be cleaned and drained before being used to preserve rice. Put the dried rice into a bottle, and friends who can accept the taste of Sichuan pepper can also prepare a few peppercorns and wrap them in a paper towel and put them in the rice. The pungent smell of Sichuan peppercorns can effectively remove rice worms and then seal them up. In this way, the rice will not grow insects in a sealed environment, and it will not spoil for several years. Convenient and space-saving.

(2) Dried kelp preservation method
Dried kelp has a strong ability to absorb water, which can play a role in killing insects and inhibiting mold. Mix the rice and dried kelp in a 100:1 ratio and place them in a rice jar. Dried kelp should be taken out and dried every week or so, and then put back into the rice bowl, this method can be used repeatedly, which can effectively prevent rice mildew and insects. It is known that the "alginate" on the surface of dried kelp has a strong ability to absorb moisture and maintain the dryness of rice.

(3) Garlic preservation method
Peel out the garlic, prepare a clean bag, put some garlic at the bottom of the bag, then pour in the clean rice, put the garlic in the middle of the rice, and finally seal the bag and put it in a dry, cool and ventilated place. Garlic releases a sulfide that is the nemesis of insects, which can effectively prevent rice from getting wet and insects, and can be stored for 1 year without spoiling. But garlic needs to be replaced every 3 months or so.

(4) Orange peel preservation method
Usually, after eating the oranges, the peel is dried and buried in the rice. Tangerine peel contains citral, which acts as a repellent of bugs. This method is simple and easy to use, and the smell of orange peel is relatively fresh.

(5) Liquor preservation law
Put a clean bottle of liquor in the container where the rice is stored, the mouth of the bottle should be higher than the rice noodles, and the lid should not be closed, and then the container should be tightly closed. Liquor can volatilize ethanol through the bottle mouth, which plays a role in insecticide and sterilization.

(6) Vacuum storage method
The rice is packed into plastic bags and then stored by vacuum machine with air extracted. In a vacuum environment, rice is isolated from the outside air and is not susceptible to pests and molds, which can be stored for a longer time.

(7) Zanthoxylum pepper insect control preservation method
You can boil the pepper water and soak the rice and dry it and put it in a bag, or wrap the pepper in gauze and put it in different positions in the rice bag. Sichuan pepper has a special fragrance that can be used to repel insects. Sichuan pepper is a natural antioxidant that can effectively prevent rice insects.

(8) Moisture absorption and preservation method of plant ash
Spread a layer of plant ash at the bottom of the rice tank, pour the rice that is dried and blown into the tank, and put the rice cylinder cover tightly and place it in a cool, dry and ventilated place. Grass ash has a hygroscopic effect, which can keep the rice dry and prevent the rice from being damp and insects.

4. The treatment method after get worm

If the rice has worms, it can be placed in a well-lit place to dry for a day and then sifted, and then sealed and placed in the refrigerator to freeze the dead eggs.
When you find a rice worm, don't panic at first. Leave the rice in a well-lit place to dry for a day, and it is important to note that good light here does not equate to sun exposure. Exposure to sunlight may make rice taste worse, and choosing a well-lit place is to make the rice worms feel stimulated by the light, making it easier to crawl.
After a day of drying, it is sifted. Sieving can effectively remove rice worms, eggs, and rice grains and debris destroyed by rice worms in rice. During the sieving process, a fine sieve can be used, and the sieve is gently shaken to allow the rice to pass through the sieve holes, while the rice worms and impurities are left on the sieve.
After sifting, the rice is sealed in separate packs. Rice can be sealed in small portions or sealed containers. The purpose of this is to prevent the rice worms from breeding again, but also to facilitate storage and use.
Finally, place the sealed rice in the freezer compartment of the refrigerator. The low temperature environment of the freezer compartment of the refrigerator can freeze the eggs in the rice, thus effectively preventing the rice worms from hatching again. In general, leaving the rice in the freezer compartment of the refrigerator for a period of time, such as a week or so, can ensure that the eggs are completely frozen to death.
According to statistics, at the right temperature, rice worms reproduce very quickly. Through this method of drying, sifting, sealing and freezing, the problem of rice insects can be effectively solved, so that our rice can continue to be safe to eat.
It is important to be reminded that in the process of handling raw insect rice, it is necessary to be patient and careful to ensure that every step is in place to ensure the quality and safety of the rice.

5. Precautions and summary

(1) Pay attention to moisture-proof
Rice has strong hygroscopicity, so it should be stored in a cool, dry and easily ventilated place, not against the wall, and usually placed on the backing board to prevent moisture. For example, in summer, it is especially important to pay attention to moisture-proof rice storage, which can be stored in the refrigerator to reduce the oxidation of rice oil and the breeding of rice worms. At the same time, you can put some hygroscopic substances such as desiccant or lime in the rice bag to help absorb moisture.

(2) Insecticide prevention measures
Avoid mixing with insect-prone foods: Rice should not be stored at the same time as fish, meat, vegetables and other foods with high moisture, otherwise the rice will absorb water and be prone to mildew or insects.
Use natural insect repellents: such as Sichuan pepper, garlic, dried kelp, etc. Sichuan pepper is a natural antioxidant that emits a special smell that can repel insects; Garlic has a bactericidal effect, which can prevent mildew in rice and effectively prolong the storage time of rice; Dried kelp has a strong ability to absorb moisture and has an insecticidal and mold-inhibiting effect.
Pay attention to regular inspections: the container in which the rice is stored may absorb nearby odors, affecting its quality. So, every once in a while, check the container and remove dirt to make sure the inside of the container is clean and odor-free.

(3) Avoid pairing with foods
Rice is compatible with some foods such as legumes, acidic foods, sugars, fatty foods, milk and dairy products, honey, bracken, red beans, alkaline foods, etc. At the same time, intake may cause malnutrition, indigestion, stomach discomfort, blood sugar fluctuations, increase gastrointestinal burden, cause indigestion and other problems. It should be reasonably matched in the diet, which is conducive to good health.
Summary: As an important staple food in our daily lives, it is essential to store rice correctly. By understanding the appropriate storage environment conditions and mastering the practical preservation methods and precautions, we can effectively prevent rice from becoming insects and mold, prolong the storage time of rice, and ensure the quality and safety of rice. When storing rice, it is necessary to choose the appropriate method according to the actual situation and check the condition of the rice regularly. Only in this way can we enjoy delicious, nutritious rice at all times.
