Summary
This study presents a rapid method for detecting estrogenic compounds in animal tissues. The technique ensures accurate quantification and confirmation of various substances, crucial for food safety.
Area of Science:
- Food Safety and Analytical Chemistry
- Veterinary Toxicology
Background:
- Estrogenic substances can contaminate animal tissues, posing risks to human health.
- Accurate detection methods are essential for regulatory compliance and consumer protection.
Purpose of the Study:
- To develop and validate a high-throughput method for screening, quantifying, and confirming estrogenic compounds in bovine tissues.
- To establish sensitive detection limits for a range of relevant estrogenic substances.
Main Methods:
- Combined solid-phase extraction (SPE) and liquid/liquid extraction for sample preparation.
- Gas chromatography/mass spectrometry (GC/MS) with selected ion monitoring (SIM) for analysis.
- Analysis of diethylstilbestrol, dienestrol, hexestrol, zeranol, taleranol, zearalanone, zearalenone, zearalenol, estradiol, and estriol.
Main Results:
- Achieved rapid sample preparation and high throughput for multiple estrogenic compounds.
- Established detection limits ranging from 50 to 150 parts per trillion (ppt).
- Successfully applied the method to bovine liver, muscle, and kidney tissues.
Conclusions:
- The developed method is effective for the sensitive and reliable analysis of estrogenic substances in animal products.
- This technique supports robust monitoring programs for ensuring the safety of animal-derived food.
