The methods are as follows:

First, when you buy multiple bags of rice or flour, don't unpack them all. It's better to unpack one bag and pour it into a container to seal it, because both rice and flour still have the function of breathing. If the container is always open, it will absorb moisture in the air, and the moisture content of flour will change with the environmental humidity. The greater the humidity, the easier it is for flour to agglomerate.

2. The container for storing rice and flour must be placed in a dry and ventilated place, and it is not recommended to put it in a kitchen with turbid and humid air. Keeping the environment clean and dry can reduce the breeding of pests and microorganisms, thus reducing the chance of rice and flour being polluted.

3. separating the old from the new, rice and flour are prone to insects when stored for a long time. therefore, rice and flour should be bought in small bags as far as possible, and it is advisable to buy them frequently, so as not to breed eggs on the old surface at the bottom of the container due to long storage time. It is best to clean the container with a dry rag after eating a bag, and then pour in a new one.

fourthly, we can put 5g dried pepper (or dried orange peel) in several net bags and put them at the bottom, middle and top of the sealed container for storing rice and flour, so as to prevent the breeding of insects and bacteria. Because Zanthoxylum bungeanum is a natural antioxidant, it has a special fragrance. And Mi Chong is very sensitive to the smell, and he avoids this special smell.
