Changes of Water Migration and Texture Characteristics of Oil-tea Camellia Seeds during Fresh Storage

In order to clarify water migration and textural changes in oil-tea camellia seeds during fresh storage after harvest, low-field nuclear magnetic resonance and magnetic resonance imaging techniques were used to clarify moisture state and distribution law and textural profile analysis was used to monitor the changes in the texture characteristics taking the oil-tea camellia seeds produced in Guizhou Province as test materials. And correlation analysis was carried out. The results showed that the water content of the oil-tea camellia seeds decreased continuously during storage. The water content of Qianyu 1 decreased from 33.86%±3.03% (0 d) to 8.64%±0.24% (56 d), and that of Xianglin 210 decreased from 53.03%±3.36% (0 d) to 10.73%±0.25% (56 d). The rate of decrease in kernel water content was higher than that of the oil-tea camellia seeds. The proportion of non-flowable water was the highest in the oil-tea camellia seeds, whereas that in Qianyu 1 decreased to 62.89% and that in Xianglin 210 decreased to 60.64%
