Abstract: Rice consists of rice husk and brown rice, the content of fatty acid in brown rice is an important index to evaluate whether rice grain is suitable for storage. In order to find out the relations and correlation of the fatty acid content of rice，brown rice and rice husk, 26 samples were selected in this experiment. The results showed that the fatty acid content of rice was positively correlation with the fatty acid content of brown rice and rice husk, the correlation coefficient of the fatty acid content of rice and brown rice reached 0.9207; the fatty acid content of brown rice was negatively correlated with the rice husk. It is feasible to determine whether the rice grain is suitable for storage by measuring the fatty acid content of rice in place of the fatty acid content of brown rice.

Key words: rice, brown rice, rice husk, fatty acids
