Fifteen official food control laboratories participated in a collaborative study of a spectrophotometric method to determine cyclamate in a soft drink and a dessert at concentrations of 90-311 mg/L and 202-526 mg/kg, respectively, with blind duplicates and a blank. Average recovery from the soft drink was 97.5%, and from the dessert, 98.6%. Reproducibility relative standard deviations were 4.7-6.5% and 6.9-8.5%, respectively. The outlier percentage was 5.5%. This study complements an earlier work by leading Nordic food laboratories and was designed according to the latest recommendations. The results of this study were compared with those of the earlier collaborative study and with general collaborative results obtained by AOAC.
15个官方食品控制实验室参与了一项分光光度法的协作研究，该方法用于测定软饮料和甜点中的甜蜜素，软饮料中的浓度为90 - 311毫克/升，甜点中的浓度为202 - 526毫克/千克，带有双盲重复样品和空白样品。软饮料的平均回收率为97.5%，甜点的平均回收率为98.6%。再现性相对标准偏差分别为4.7 - 6.5%和6.9 - 8.5%。异常值百分比为5.5%。本研究补充了北欧主要食品实验室早期的工作，并根据最新建议设计。本研究结果与早期协作研究结果以及美国官方分析化学师协会（AOAC）获得的一般协作结果进行了比较。
