| 气调剂储粮技术通过消耗密闭空间内氧气，营造低氧储藏环境，从而实现防虫抑霉、保持粮食品质的目的。但稻谷低氧胁迫后复氧会出现氧化爆发现象，从而影响稻谷品质。为探明低氧后复氧是否会影响稻谷品质，本文研究了黄华占稻谷在氧气体积分数0%~2%、2%~6%、6%~10%、10%~15%和15%~21%储藏后复氧6个月期间的品质变化。结果表明： 复氧6个月期间，实验组的水分含量显著高于对照组，真菌孢子数显著低于对照组，氧气体积分数与复氧后黄华占水分含量呈显著负相关，与孢子数呈显著正相关。与对照组的脂肪酸值持续上升趋势不同，实验组的脂肪酸值在0~60 d先上升而后下降至刚复氧状态，再缓慢上升。复氧后随着储藏时间延长，20℃储藏温度可以更好的维持黄华占的品质。本研究有助于解析稻谷在气调期间和气调结束后品质变化，且可为气调储粮技术创新及保证粮食储藏安全提供参考。 |
| 英文摘要: |
| Controlled atmosphere storage technology maintains grain quality and achieves pest control and mold inhibition by consuming oxygen within a sealed space to create a low-oxygen environment. However, reoxygenation after low-oxygen stress in rice can lead to oxidative burst phenomena, thereby affecting rice quality. To investigate whether reoxygenation after low-oxygen conditions affects rice quality, this study examined the quality changes of Huanghuazhan rice during six months of reoxygenation following storage under oxygen volume fractions of 0~2%, 2~6%, 6~10%, 10~15%, and 15~21%. The results showed that during the six months of reoxygenation, the moisture content in the experimental groups was significantly higher than that in the control group, while fungal spore counts were significantly lower. Oxygen volume fraction was significantly negatively correlated with the moisture content of Huanghuazhan rice after reoxygenation and significantly positively correlated with spore counts. Unlike the continuous increase of fatty acid values in the control group, the fatty acid values in the experimental groups first increased during 0-60 days, then decreased back to the initial reoxygenation level, and then slowly increased again. After reoxygenation, as storage time extended, a storage temperature of 20?°C better maintained the quality of Huanghuazhan rice. This study helps elucidate the changes in rice quality during and after controlled atmosphere storage and provides a reference for the innovation of controlled atmosphere storage technology and the assurance of grain storage safety. |
