The operational efficiency of a method for colorimetric determination of furfural in citrus juices is improved by inclusion of a concentration-screening step prior to the color reaction. The absorbance at 277 nm may be used to determine the appropriate dilution for samples exceeding the recommended maximum furfural concentration in the reaction mixture. As much as 1 h per sample may be saved in the time required for analysis.
通过在比色反应之前加入浓度筛选步骤，提高了柑橘汁中糠醛比色测定方法的操作效率。277nm处的吸光度可用于确定反应混合物中糠醛浓度超过推荐最大值的样品的适当稀释度。每个样品的分析时间最多可节省1小时。
