Thus, monitoring pesticide residues in such matrixes is crucial for food safety and to comply with national as well as international regulations for export\/import purposes. However, accurate analysis of pesticide residue in chili powder is challenging due to its complex nature.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To develop and validate a high-throughput LC-MS\/MS method for the quantification of multiclass pesticide residues in a complex chili powder matrix.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The acetonitrile-based extraction method was optimized for chili powder samples.

The LOQ was determined to be 0.005\u2009mg\/kg for 135 analytes, with recovery ranging from 70 to 110%, and intra-day and inter-day precision (RSD) were below 15%. Analysis of market\/incurred samples and measurement uncertainty further provided more confidence in the method performance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The developed LC-MS\/MS method provides a robust, sensitive, and high-throughput approach for the quantification of pesticide residues in complex chili powder.
