摘　　要：本文采用乙酰丙酮分光光度法测定香菇在不同温度下浸泡不同的时间的浸出液中甲醛的含量,方法在甲醛含量为0.5-5mg/L范围内呈良好的线性(r2=0.9998)。实验结果表明,用60℃的水浸泡40min或40℃的水浸泡60min可最大限度地浸出香菇中的甲醛。The content of formaldehyde in the lixivium of mushroom was determined by acetylacetone Spectrophotometry. A good linear range of 0.5-5mg/L in formaldehyde content（r2=0.999）. The pretreatment conditions of temperature and time were investigated. The optimum conditions are as follows： 60℃, 40 min utes or 40℃, 60 min utes.
