用薄层色谱分析法研究了一些理化方法去除赤霉病麦中“致吐毒素”的效果。结果表明:以食盐水漂浮、5％NaHSO_3浸泡60min和5％NaHSO_3漂浮后再浸泡30min去毒效果最好,可使毒素减少80％以上,含量均<500μg/kg;泥浆水漂浮使毒素含量降至670μg/kg以下。提示:食盐水和泥浆水漂浮为经济实用的方法,NaHSO_3可处理漂浮分离出的病麦。 Some physical and chemical methods were used to remove the effect of “detoxification toxin” in Fusarium graminearum by TLC. The results showed that the toxin had the best detoxification effect when floating with salt water, soaking in 5% NaHSO 3 for 60min and 5% NaHSO 3, and then soaking for 30min, which reduced the toxin by more than 80% and the contents were all less than 500μg / kg. To 670 μg / kg or less. Tip: Saltwater and mud water float as an economical and practical method, and NaHSO_3 can handle the floating, isolated wort.
