Based on the form and location of water in wood, it can be classified into three types: free water, adsorbed water, and bound water. The primary water in wood consists of free water and adsorbed water, while the content of bound water is very low. In daily use, adsorbed water plays a crucial role in determining the properties of wood.

Nuclear magnetic resonance (NMR) and its imaging techniques are effective methods for studying diffusion and can be applied to investigate the distribution and migration of water in food systems.

The fiber saturation point (FSP) refers to the specific moisture content at which the bound water in the cell walls of lignocellulosic materials is fully saturated, while there is no free water present in the cell cavities or intercellular spaces.

Monitoring changes in water states in carrots during infrared drying under different conditions using low-field nuclear magnetic resonance (LF-NMR).

Water distribution information of four dried strawberry samples obtained using low-field nuclear magnetic resonance (LF-NMR) technology.

Prepare bean pods and soybeans at different growth stages. Use T₁-weighted imaging to observe the spatial distribution of oil, in order to identify the spatial accumulation process of oil in soybeans during various developmental stages.

Low-field nuclear magnetic resonance (LF-NMR) and its imaging technique (magnetic resonance imaging, MRI) have been studied and applied in the field of food and agricultural product analysis due to their advantages of rapid, non-destructive detection and the ability to obtain both temporal and spatial signal information from samples.

Root systems play a vital role in plant growth and development. However, because roots grow within opaque soil environments, the lack of rapid, accurate, and non-destructive in situ observation methods has hindered in-depth research on plant root systems.
