How should rice be stored
Rice is white rice that lost its hulls and seed coats through rice processing. The endosperm is in direct contact with the air and is sensitive to the effects of temperature and humidity. The hygroscopicity is strong and the amount of bacteria is high. Pests and molds are easy to harm directly. Rice under high temperature and high humidity conditions, high respiratory intensity, easy to heat, rice moisture content exceeds safety standards, the situation is prone to fever. The powder and broken rice contained in rice not only increase the moisture absorption area, but also block the spread of moisture and heat, and make the rice more susceptible to mildew. As the storage time prolongs, under the adverse conditions of the outside world, the color odor decreases, and the fatty acid value decreases. The increase will make the rice sour, aging degeneration of colloidal substances, decreased viscosity, decreased water absorption, reduced food quality.

Based on the above situation, the following methods are recommended for storing rice:
1, according to the season, the amount of storage. During the year, according to different seasons, the stock of rice in the home can be adjusted in a timely manner. Under normal circumstances, the weather temperature in summer is relatively high, and the air humidity is relatively high. Rice is susceptible to mildew and mildew. It is difficult to store, and it should be saved. It is best to buy food. In autumn and winter, the temperature is low, and the climate is dry. The rice is not susceptible to the environmental impact of its food quality, and can be stored in adequate amounts.
2, timely ventilation, moisture and heat insulation. Whether it is a supermarket, a food court or a family, the preservation of rice in the summer should be protected against moisture and heat and stored in a cool, dry, and easily ventilated place. Specific attention should be paid to three aspects: Attention to moisture, not mixed. Because rice has strong hygroscopicity, moisture should be taken care of and should not be mixed. For example, rice should not be placed on a wall, usually on a pad to prevent it from getting wet; rice should not be stored together with fish, meat, vegetables, and other foods that are high in moisture, otherwise the rice absorbs water and is susceptible to mildew or worms. Take care of heat insulation and keep away from heat sources. In a high temperature environment, rice is prone to mildew, so it should be insulated and kept away from heat. For example, rice should not be stored in the kitchen. Because of the high temperature and humidity of the kitchen, the quality of rice is greatly affected. Rice should not be placed near the stove. Because it is too close to the heat source, the rice will heat and cause quality changes. Pay attention to dry, avoid exposure. If the rice is damp, it should be placed in a cool and ventilated place and spread dry to blow through. Avoid exposure. Because the exposure will cause the moisture to quickly dissipate, some of the particles will shatter, leading to a loss of food quality. If you put it back into a damp environment, it will be more susceptible to moisture, mildew, and insects.
3, natural hypoxia, scientific pest control. In the high temperature and high humidity season, there are many kinds of historical experience in preventing rice insects. For example, put a few dry garlic (garlic food) in a rice bag; or take pepper or fennel, pack into a number of gauze bags, put it in a rice bag and seal it. However, with these methods for a long time, Miley will retain some odor and thus affect the consumption of food. The pests will also be resistant to certain odors and will still not achieve the desired results. So, how can we prevent insects from affecting food? According to grain experts, eggs are difficult to grow into larvae in the presence of hypoxia or lack of oxygen. Therefore, household rice can be sealed with plastic membranes and oxygen-free. The method of deoxygenation preserves rice and can not only achieve pest control effect but also not affect the eating quality of rice.
Rice preservation should pay attention to the following points:
1. Rice should not be stored at the same time as fish, meat, vegetables and other foods with high moisture, otherwise rice will absorb water and cause mildew.
2, rice should not be stored in the kitchen; because the kitchen temperature is high; humidity, great impact on the quality of rice.
3, rice should not rely on the ground, usually on the pad, the purpose of doing so is also to prevent moldy rice or insects.
4, rice should not be placed near the stove. If it is too close to the heat source, the rice will produce heat and cause quality changes.
What to do after rice bugs
After rice is moth-eaten, people often like to put rice in the sun for exposure. This not only fails to kill rice worms, but also counterproductively, because two or three days later, rice worms in rice will increase unabated, and After exposure, rice loses its moisture and affects its taste. The correct approach is to put wormy rice in a cool, well-ventilated place where the insects can crawl out slowly and then sift through a sieve.
Rice insects are more, but also use phosphazene and organic acid smoke. The specific approach is as follows: In the veranda or in an idle room, place the worm's Milian bag in a tightly sealed plastic bag, that is, a fumigation bag, and then put a cup or cup inside the fumigation bag. Grams of vinegar; if the food does not exceed 500 kg, put one gram of zinc phosphatide into the cup or bowl of vinegar, and immediately seal the fumigation bag without stirring. Sealed for 5-10 days, can kill all the pests inside. After 2-3 days, remove the vinegar and the residue.
