Abstract While pyrethroids and other pesticide residues in cocoa beans have been reported previously, no report on pesticide residues in cocoa powder has been documented. In this paper, pyrethroids residues in cocoa powder were investigated. First, a simple method was specifically built and validated for cocoa powder pyrethroid analysis. The method only employs low volume extraction and d-SPE clean-up before quantification. The linearity of the method was good (r > 0.9992) for lambda-cyhalothrin, permethrin, cypermethrin, fenvalerate and deltamethrin. The repeatability (%RSD) and accuracy (% recovery) are acceptable. For the reproducibility, no significant differences were found between two analysts who conducted the same experiment. Weak matrix effect (

印度尼西亚可可粉中的拟除虫菊酯残留：方法开发、分析和风险评估

摘要 虽然以前曾报道过可可豆中的拟除虫菊酯和其他农药残留，但没有关于可可粉中农药残留的报告。本文对可可粉中拟除虫菊酯的残留进行了研究。首先，专门建立并验证了一种用于可可粉拟除虫菊酯分析的简单方法。该方法仅在定量前采用小体积萃取和 d-SPE 净化。该方法对 λ-三氯氟氰菊酯、氯菊酯、氯氰菊酯、氰戊菊酯和溴氰菊酯的线性良好 (r > 0.9992)。重复性 (%RSD) 和准确度 (% 回收率) 是可以接受的。对于重现性，进行相同实验的两名分析人员之间没有发现显着差异。弱矩阵效应（
