The work aims to take japonica rice of the current year stored in grain depot as the research object, to research the characteristics of storage quality and processing quality of rice in high voltage alternating electric field (HVAEF) and nitrogen-filling gas-conditioned (NFGC) environments, so as to preliminarily explore the application of HVAEF in rice storage. A two-factor and two-level experiment was carried out at 28 ℃ to investigate the quality changes of rice stored in four treatment environments with NFGC and HVAEF. The results showed that the NFGC treatment significantly slowed down the decrease in moisture content, the increases of fatty acid value, yellow grain rice rate, yellowness index, and broken rice rate of stored rice grains. HVAEF had a significant inhibition effect on the fatty acid value, yellow grain rice rate, and yellowness index and broken rice rate. And the inhibitory effect on the fatty acid value and the yellowing were improved to different degrees compared with NFGC treatment. In addition, HVAEF and NFGC treatment had no significant effect on brown rice rate and polished rice rate. In conclusion, both HVAEF and NFGC treatment environments in rice storage can play a good role in rice quality preservation, and HVAEF treatment has certain advantages in inhibiting fatty acid value and yellowing of rice grain. This provides technical guidance for the promotion and application of HVAEF on rice storage.
