What food can be stored for a long time in high temperature weather without preservatives?

All kinds of rice and miscellaneous beans (starchy beans such as red beans, mung beans and broad beans, excluding soybeans) have low moisture content, so they are all dry goods and can be preserved for a long time.

Rice and miscellaneous beans must be stored in a dry and ventilated place.

If rice and miscellaneous beans are sealed and stored in the freezer of the refrigerator, you can really eat them whenever you want, without worrying about mildew.

The following methods are recommended to store rice:

1, according to the season, appropriate storage. During the year, according to different seasons, the rice inventory at home can be adjusted in time. Under normal circumstances, in summer, the weather temperature is high and the air humidity is high. Rice is easy to be damp and moldy, so it is not easy to store, so it is best to store it less and eat it when you buy it. In autumn and winter, the temperature is low and the climate is dry, so rice is not easily affected by the environment and can be stored in moderation.

2, timely ventilation, moisture-proof heat insulation. Whether in supermarkets, vegetable markets or families, rice should be moisture-proof and heat-proof, and stored in a cool, dry and ventilated place as much as possible. Specifically, we should pay attention to three aspects: pay attention to moisture prevention and do not mix storage. Because rice is highly hygroscopic, it should be moisture-proof and cannot be mixed. For example, rice should not hit the ground against the wall, but should generally be placed on a mat to prevent moisture.

Rice should not be stored with fish, meat, vegetables and other foods with high water content at the same time, otherwise rice will absorb water and be prone to mildew or insects. Pay attention to heat insulation and stay away from heat sources. In high temperature environment, rice is easy to be heated and moldy, so pay attention to heat preservation and stay away from heat sources. For example, rice should not be stored in the kitchen, because the high temperature and humidity in the kitchen have a great influence on the quality of rice; Don't put the rice beside the stove, because it is too close to the heat source, it will heat up and cause quality changes. Pay attention to dry in the shade and avoid exposure to the sun.

If the rice is wet, it should be spread in a cool and ventilated place to dry and blow thoroughly to avoid exposure. Because exposure to the sun will make the water disappear quickly, some particles will be broken, and the edible quality will be greatly reduced. If it is put back in a humid environment, it will be more susceptible to moisture, mildew and insects.
