TD-NMR Applications in Food & сельское хозяйство

Water molecule is the key factor of food quality. It influences the food’s taste, storage and process. В то же время, the oil content is also important to food quality. Кроме того, in the process of the grains and oil’s production, the oil content of oilseeds, oilseed residue and feedstuff is very important. NIUMAG’s low-field NMR instruments can easily measure the water phase, water distribution, oil content and oil distribution of food and grains.

Sea cucumber swelling process studies

（a）Water activity changes during the immersion process.

（b）Migration of various phase water during the immersion process

During the initial stage of immersion, the external water mainly transformed into intracellular water after entering internal body, the bound water (A22) also increased.
With the proceeding of immersion, the internal structure of cucumber continually expanding, the bound water (A22) migrated gradually to the free water (A23).
Also during the immersion process, the activity of body water increased.
