| 摘 要： | 基于对微型光谱仪的二次深度研发，构建了新型食品安全检测微型光谱分析系统，并采用标准加入法，对牛肉粒中的食品添加剂山梨酸进行快速定量检测。结果表明，采用标准加入法消除了样本基体成分的干扰，牛肉粒中山梨酸在0～10.0 mg·L-1质量浓度范围内有良好的线性关系(R2=0.998 9)，山梨酸加标回收率为99.2%～99.5%，RSD(n=5)为0.14%。该微型光谱分析系统在食品添加剂检测应用方面表现出良好的实用化前景。 |

| Abstract: | A homemade micro-spectrometer analytical system was developed for the quantitative determination of the sorbic acid in the food based on the photometric principle. And with the standard addition method it was applied to eliminate the interference coming from the food substrate. The detecting result illustrated a good relativity in the range of 0～10.0 mg·L-1 with the linear correlation coefficient of 0.998 9, and the sample recovery was 99.2%～99.5% with RSD of 0.58%. The micro-spectrometer analysis system has shown potential prospective application in the fields of rapid and high performance detection for food additives. |
