Ginger powder

Ginger powder or dried ginger powder mainly refers to the powder that is crushed and sieved after the ginger is dried in the shade. There are three main points.

1. Drying method. Fresh ginger contains a lot of valuable volatile oil, so it is better to use dry drying in the shade. Other methods such as heating and air blowing will cause the loss of volatile oil more seriously.

2. The mesh number of sieving, because the raw powder is crushed with plant raw materials, it contains a lot of wood fiber, which is not easy to sieve. Usually, each manufacturer passes 20-60 mesh. Please pay attention to this when making product information.
