Rice after a long time of storage, due to the temperature, moisture and other effects, rice in the starch, fat and protein, etc. will undergo a variety of changes, so that the rice to lose the original color, aroma, taste, nutrients and eating quality decline, and even bugs. Rice can be used after the birth of insects, cool sieve insects, frozen insecticide, organic acid fumigation three methods.
1, cool sieve insects
Rice insects, people often like to put the rice in the sun exposure, this does not achieve the purpose of killing the rice insects, but it will be counterproductive, because after two or three days, rice in the rice will be no reduction in the rice bugs, and exposure to sunlight after the loss of moisture and affect the taste. The correct approach is to put the insect rice in a cool, ventilated place, so that the insects slowly crawl out, and then sieve a sieve.
2, Freezing to kill insects
If the rice is not a lot of insects, you can put the rice in a plastic bag, the bag tightly tied, placed in the refrigerator freezer, 48 hours after the removal of the rice can be killed in the moths.
3, Organic acid fumigation
Rice more insects, but also the use of phosphorus and zinc plus organic acid fumigation. Specific practices are as follows: in the lanai or unused room, the rice with bags of insects in a sealed plastic bag, that is, fumigation bag, and then in the fumigation bag, put a cup or Wan, 50 grams of vinegar; if the grain is not more than 500 kilograms of zinc phosphide, a gram of paper wrapped into the cups or bowls filled with vinegar, no need to stir, and then immediately seal the mouth of the fumigation bag. Sealed for 5-10 days, it can kill all the pests inside. Afterward, disperse the gas for 2-3 days, take out the vinegar water and residue to get rid of.
Also, you can look at the degree of rice bugs, if the degree is less, less bugs, can be placed in the shade, sieve a sieve of insects before eating. If we find that the rice has been a long period of time, the worms have developed all around the rice, the rice may also have appeared hollow and broken topic, this time the rice is a more serious degree of insects, then you can not continue to eat, you can take it to feed the chickens.
Effective way to prevent rice bugs are as follows:
Worm eggs in the case of low or no oxygen is difficult to develop into larvae, so the family storage of rice can be used in plastic film anoxic sealing, the use of this method of preservation of natural deoxidization of the rice, not only to achieve the effect of insect prevention, but also will not affect the eating quality of rice. The rice can be preserved by this natural deoxygenation method, which can achieve the effect of pest control without affecting the edible quality of rice. Of course, you can also use the following methods to prevent rice insects:
1, with lime to prevent rice insects
In the bottom of the container containing rice to spread some lime, the top of the plastic sheet, and then put rice, the container cover tightly, can prevent insects.
2, white wine to prevent rice worms
In the bottle filled with 50 grams of white wine, not cover the lid, and then the bottle containing wine buried in the rice, the bottle mouth higher than the rice surface, will be the rice bag seal. Due to the weak respiration of the rice, so that the air is less and less, the volatile ethanol in the wine has an insecticidal and bactericidal effect, so it can prevent the birth of insects.
3, garlic to prevent rice insects
In the storage of rice containers scattered in a few cloves of garlic, the container cover tightly, the same can play the effect of insect prevention.
4, pepper to prevent rice insects
First in the pot to put the right amount of water, and then take a dozen peppercorns in the pot with the water to cook, and then put the bag into the soaked, fished out to dry. Load rice, with gauze sewing a few small pockets filled with some pepper, respectively, placed in the rice under the upper and middle, tighten the mouth of the bag, placed in a cool ventilated place, rice will not be born.
5, kelp to prevent rice worms
Because dry kelp has a strong ability to absorb moisture, so play a role in killing insects and inhibit the role of mold. Put some dry kelp in the rice, rice and kelp ratio of about 100:1, every 10 days or so removed and dried, and then put back into the rice tank. This method can be used repeatedly, can effectively prevent the rice mold and insects.
6, bottled to prevent rice insects
You can bag the rice into a beverage bottle separately, can also be saved for a long time without insects. Rice utensils should be clean and tight. It is best to keep the rice in a jar, altar or barrel with a tight lid. If you use cloth bags of rice, you should put a plastic bag outside the cloth bag and tie the bag tightly.
Rice preservation should pay attention to the following points:
1, rice should not be stored at the same time with fish, meat, vegetables and other high water content of the food, otherwise the rice absorbs water, resulting in mold.
2, rice should not be stored in the kitchen; because of the high temperature of the kitchen; humidity, the quality of rice greatly affected.
3, rice should not be against the wall on the ground, usually on a mat board, the same purpose is to prevent the rice mold or insects.
4, rice should not be placed next to the stove. Too close to the heat source, the rice will heat and cause quality changes.
