Abstract Title:

Pesticide Residues in Barley and free Hop APA Style Beer: Impact on Food Safety and By-products

Biography:

I am a chemical technologist and an advanced student in the Bachelor's Degree in Food Analysis.With a solid background in food chemistry, that has oriented her career toward researching pesticides in products of high national importance. My work focuses on the development and validation of analytical methodologies to ensure food safety and regulatory compliance. The interest in innovation and quality control motivates me to contribute to the advancement of the agri-food sector through studies that promote safer and more sustainable practices.

Research Interests:

This study explores pesticide residues in barley, malt, and throughout the beer production process. Commercial barley samples (CB) were collected from producers in the Paysandu region, along with a control (without chemical managment-WC) sample. A fortified sample (FB) spiked with triflumuron, epoxiconazole, pyraclostrobin, propiconazole, isopyrazam, fluxapyroxad, and florasulam was also obtained. The brewing process, including malting, mashing, boiling, fermentation, and maturation, was conducted under controlled conditions for the three barley samples (CB, WC and FB). QuEChERS methodology and direct injection were used for the analysis of solid and liquids, respectively, using liquid chromatography-tandem mass spectrometry (HPLC-MS/MS)
