摘要
不同温度下,对常规储藏和气调储藏的籼糙米各项储藏品质指标的研究表明:随着储藏时间的延长和储藏温度的升高,籼糙米的生活力、发芽率、过氧化氢酶活动度逐渐降低;脂肪酸值、电导率和丙二醛含量逐渐升高.低温时,两种储藏方式对籼糙米品质影响区别不大,但随着温度的升高,除生活力和发芽率比常规储藏降低较快之外,充氮气调的其余指标均比常规储藏的变化缓慢.35℃下储藏120d后,常规储藏糙米的电导率已由46.3μS/cm增至97.6μS/cm,而气调储藏仅增至88.4μS/cm.因此,低温可较好地保持籼糙米的品质,充氮气调可以有效减缓高温对籼糙米品质的影响,但不适用于种子粮的储藏.
We studied the storage quality indicators controlled atmosphere storage at different temperatures and catalase activity of the Indica brown rice decreased of Indica brown rice under conventional storage and The results showed that： the viability, germination rate, gradually, and the fatty acid value, conductivity and MDA content increased gradually as the storage time prolonged and the storage temperature rose. At low temperature, no large difference in the quality of Indica brown rice existed between the two storage methods; but the quality indicators except for the viability and the germination rate of Indica brown rice under controlled atmosphere storage changed slowly in comparison with the conventional storage as the temperature rose. After storage at 35 ℃ for 120 days, the conductivity of Indica brown rice under conventional storage increased from 46.3 μS/cm to 97.6 μS/cm, and the conductivity of Indica brown rice under controlled atmosphere storage increased to 88.4 μS/cm. Accordingly, low temperature could well keep the quality of Indica brown rice, and controlled atmosphere storage could effectively suppress the influences of high temperature on the quality of Indica brown rice, but was not suitable for seed grains.
