Multiresidue analysis of pesticides in Turmeric (Curcuma longa) powder by GCMS/MS using QuEChERS’ extraction method

Turmeric is a plant indigenous to south Asia, with majority of its production coming from India. The rhizome of the plant is used to produce powdered turmeric, which is used in food, cosmetics and some medicines. It is one of the most essential spices used extensively in Indian cooking. The intensive use of agrochemicals during its cultivation has given rise to concerns over consumer’s exposure to pesticide residues and associated health risks. Hence, it is important for turmeric producers and regulators to ensure that presence of residual pesticides meet compliance criteria. The Minimum Residual Limit (MRL) as per EU guideline ranges from 5 ppb to 5000 ppb level. This study reports a sensitive and reliable analytical method for quantitative analysis of multipesticide residues in commercially available turmeric powder by using GCMS/MS triple quadrupole system.
