The state of water in corn can be divided into free water and colloidal water.

Free water can also be called "free water". It is the water that exists in the interstitial space and has the properties of ordinary water. When the water in corn is tested, the measurement object is free water.

Colloid-bound water is also called "bound water". It combines with the proteins and carbohydrates in the cell to form a relatively firm colloidal water. It does not have the properties of ordinary water.

Corn has moisture absorption and moisture dissipation properties. Through the water, the free water content can be increased by absorption. When the moisture is higher, the difference between the strength of the cortex and the endosperm increases, which is beneficial to milling, but the scattering of corn and its intermediate products will change. difference.

When moisture is not adjusted, the moisture distribution in each part of the corn kernel is uneven. Generally, the moisture of the corn husk is lower than that of the endosperm. After adjustment, the moisture of the corn can be higher.
