霉菌呼吸作用是粮食储藏陈化和霉变的关键因素,为真实了解小麦储藏期间霉菌的呼吸效果,开展了储藏小麦霉菌所产生CO2浓度变化的探索工作。通过对照不同条件下霉菌呼吸作用中CO2浓度与超导强磁场中不同强度和温度所对应试验数据的分析研究表明:在菌丝生长期时,CO2浓度的增加快于其他阶段,霉菌呼吸旺盛,它是小麦储藏中霉菌活动强化和可能出现霉变关键时期;在5 T(Tesla,特斯拉)和7 T的强磁场中,霉菌呼吸中CO2浓度出现不同程度的减小,曲线呈现平坦变化或减小之势,同时脂肪酸值也出现类似的变化,这显示了强磁场的处理具有抑制霉菌呼吸作用。
Mold respiration is a key factor in the aging and mildew of foodstuffs. In order to truly understand the respiration effect of mold during storage of wheat, the exploration of the changes of CO2 concentration in storage of wheat molds has been carried out. By comparing the CO2 concentration under different conditions with the experimental data of different intensities and temperatures in the superconducting strong magnetic field, it was found that the CO2 concentration increased faster than the other stages during mycelial growth, It is a key period for mold activity enhancement and possible mildew occurrence in wheat storage. In the strong magnetic field of 5 Tesla and 7 T, the CO2 concentration in the respiration of the mold decreased to some extent and the curve showed a flat change Or decreased, with similar changes in fatty acid values, indicating that the treatment of strong magnetic fields has the effect of inhibiting the respiration of the mold.
