| 目的 以粮库收储当年的粳稻为研究对象，研究高压交变电场和充氮气调环境中稻谷储藏品质和加工品质特征，旨在初步探讨高压交变电场在稻谷储藏中的应用。方法 采用双因素两水平实验，在28 ℃下，在空气无电场、空气有电场、充氮气调无电场和充氮气调电场这4个处理环境中对稻谷进行储藏，探讨其品质变化。结果 充氮气调处理对储藏稻谷的水分含量下降，脂肪酸值、黄粒米率、黄度指数和碎米率的上升有显著减缓作用;高压交变电场储藏对稻谷脂肪酸值、黄粒米率、黄度指数和碎米率的上升有显著抑制作用，脂肪酸值和黄变抑制效果相较于充氮气调处理均有不同程度的提高。另外研究表明，电场和气调处理对糙米率和精米率均没有显著影响。结论 在高压交变电场和充氮气调处理环境中储藏稻谷都能起到较好的保质作用，电场处理对于抑制脂肪酸值和黄变有一定优势，这为高压交变电场仓储稻谷的推广应用提供了技术指导。 |

| 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. |
