Multiresidue pesticides analysis in Curcumin color additive powder using GCMS-TQ8040 NX and LCMS-8050

User Benefits

- The method involves study of LOQ on both GC-MS/MS and LC-MS/MS, based on validation parameters like linearity, recovery, repeatability and within-laboratory reproducibility. - A modified QuEChERS extraction procedure has been employed for quantifying the pesticides at trace levels from complex matrix like Curcumin powder using Ultra-Fast technologies of LCMS-8050 and GCMS-TQ8040 NX. - LCMS Method Package for residual pesticide Ver.3 and GCMS Smart Pesticides Database^TM Ver.2 from Shimadzu Corporation enables ease of optimizing instrumental method.

Introduction

Color additives are dyes, pigments, or other substances that can impart color when added or applied to a food, drug, cosmetic, or the human body. They can be found in a range of consumer products—from cough syrup and eyeliner to contact lenses and cereal. The food color curcumin (turmeric yellow) is obtained by solvent extraction of turmeric, i.e., the ground rhizomes of Curcuma longa L., with purification of the resultant extract by crystallization. In India, it has been used as a food preservative and as a spice in curry dishes. Hence, considering the heavy use of pesticides in their cultivation, it is important to analyze these plant-based color additives for the presence of residual pesticides. This application news shows validation data of the Multi- residue analysis method in complex matrix such as curcumin powder. The analysis was performed using modified QuEChERS and triple quadrupole gas chromatography (GC-MS/MS) and liquid chromatography (LC-MS/MS) system.
