At home, the number of yellow bean sprouts is controllable and safe, which is more natural and reassuring than those purchased outside. Moreover, the process itself is a kind of fun, as long as it comes step by step

1、 Soak beans

First of all, you need to choose fresh and plump soybeans, heavy soybeans or soybeans with diseases and pests, which is not conducive to normal bean sprouts. After the soybeans are selected, wash them with clean water, and then soak them in the water for one night, at least for 10 hours. After soaking, you will find some sunken at the bottom of the water, which should be taken out and removed, as well as some impurities, or damaged and injured residual beans

2、 Container

At the same time of soaking beans, we should prepare containers for yellow bean sprouts. Generally, clean basins, plates and bowls without oil can be used. Now there are special containers for bean sprouts in the market. They are two to three layers. There is a layer of water outside and a layer of water inside. Whatever kind of container must be cleaned without oil, and then lay a piece of absorbent paper at the bottom of the container

3、 Bean sprouts

Put the soaked and screened beans on clean water, rinse them slightly, and put them in a container. It is ideal to put the container at the temperature of 20-28 degrees, not more than 30 degrees. In that case, it will inhibit the occurrence of sprouts, and it is easy to mildew, and the germination speed at low temperature will be weakened. Then, what we have to do every day is to ensure that the gauze on it is in a wet state, and there can't be too much water. Clean it every day, because with the growth of the sprouts, Some of its skin and other substances will fall off. Clean them every day and use new water. Generally, bean sprouts can spit out and sprout in two to three days. Then we can maintain this work until the bean sprouts grow to the size we can eat
