鲜香菇在不同处理方式下的甲醛含量分析研究

Determination and analysis on the formaldehyde content in Lentinula edodes disposed with different methods

目的检测分析经匀浆、干燥等方式处理鲜香菇中的甲醛含量,反映处理后鲜香菇的生物活性随时间的变化情况,为香菇的储存提供数据支持。方法利用液相色谱法测定香菇甲醛含量。结果匀浆后的鲜香菇中甲醛含量随时间增长而降低,至腐烂后消失。真空包装经高燥处理的香菇中甲醛含量随时间增长呈上升趋势,而真空包装未经干燥处理的香菇,其甲醛含量呈下降趋势。结论通过连续检测鲜香菇中的甲醛含量,验证了香菇中的甲醛来源于其生理活动这一科学论断。基于此,通过检测香菇的甲醛含量判断香菇得生物活性,以观察香菇在贮藏及运输过程中的保质效果。

Objective To determine the content of the formaldehyde in the fresh Lentinula edodes diposed with different methods of grinding and drying, to reflect the change of biological activity of the Lentinula edodes over the time, which can provide theory support for the storage and transportation of Lentinula edodes. Methods The content of formaldehyde in Lentinula edodeswas detected by liquid chromatography. Results The content of formaldehyde of crashed Lentinula edodes reduced over time until they decayed, and the content of formaldehyde in the Lentinula edodes increased over time, which was vacuum packed and dried. Conversely, the content of formaldehyde reduced over time because the fresh Lentinula edodes was vacuum packed and not dried. Conclusion The change of formaldehyde content in the crashed Lentinula edodes verifies the judgment that the formaldehyde in the Lentinula edodes is produced from its physiological activity. According to this judgment, the formaldehyde content can be used to reflect the quality of Lentinula edodes during the storage and transportation.
