How to preserve a large amount of flour for a long time

The long-term storage method of a large amount of flour is as follows:

1. Flour should be stored in a sealed container, which can isolate air and moisture and has good moisture-proof effect.

2. Prepare a clean gauze, cut it into small pieces, put a spoonful of dried peppers in each gauze, wrap the gauze and tie it tightly with a rope. Make an insect-proof bag.

3. Put several insect-proof bags at the bottom of the flour barrel, then pour 1/3 flour, put several insect-proof bags, pour 1/3 flour and insect-proof bags in turn, and finally pour the remaining flour.

4. Put several insect-proof bags on the top of the flour barrel, then seal the flour barrel and put it in a cool and ventilated place. Flour is taken as needed, and insect-proof bags are put into flour, so that flour will not go bad for a year.

Why can flour be pickled with pepper?

Zanthoxylum bungeanum has a natural pungent smell, which is a very good insect repellent. It has a great stimulating effect on flour insects and can prevent eggs from hatching and drive away hatched insects. Moreover, Zanthoxylum bungeanum also has the functions of sterilization and oxidation resistance, which can prevent flour from going moldy and deteriorating.

In addition to putting pepper, we should pay attention to two points when saving flour.

1. Keep it sealed.

A lot of flour is packed in cloth bags, which has no sealing function and is easily affected by the environment, so sealed flour barrels should be used.

2. The storage environment should be cool and dry.

It is not recommended to put the flour barrel in the kitchen, because it is hot and humid there and the flour is easy to deteriorate. It is recommended to put it in a cool room.
