Could anyone recommend standardized protocols or peer-reviewed references detailing reliable extraction, separation, and quantification techniques for sulfur determination (refinery and mineral) in nuts?
Additional insights into sample preparation challenges for lipid-rich matrices like nuts would also be valuable.
Thank you for your expertise!
Hi Soheila Rezaitabar ,
for high fat commodities, a sample preparation for pesticide residue analysis is in the link: https://www.eurl-pesticides.eu/docs/public/tmplt_article.asp?LabID=500&CntID=1279&Theme_ID=1&Pdf=False&Lang=EN
For sulfur determination in nuts, methods like Parr sulfur bomb with AAS, LC-MS/MS, and wet combustion are recommended. Lipid removal and sample homogenization are crucial steps in sample preparation. These methods offer reliable extraction and quantification techniques for both refinery and mineral sulfur in lipid-rich matrices.
