Summary
Detecting hormone residues in food is crucial due to varying regulations. This study presents a sensitive method using Fast Dark Blue R Salt and chromatography to detect hormones like zeranol and estradiol below 10 ng.
Area of Science:
- Food Science
- Analytical Chemistry
- Veterinary Science
Background:
- National food regulations vary regarding hormone use in food-producing animals.
- Detecting hormone residues in food requires sensitive and specific analytical methods.
Purpose of the Study:
- To develop a sensitive method for detecting specific hormone residues in food.
- To analyze common hormones used in animal breeding.
Main Methods:
- Hormones were coupled with Fast Dark Blue R Salt for enhanced sensitivity.
- Thin-layer chromatography on high-performance plates was used with two solvent systems.
- Analysis of zeranol, estradiol, estriol, and estrone as azo dyestuffs.
Main Results:
- The developed method allows for the sensitive detection of target hormones.
- Detection limits for the analyzed hormones were below 10 ng.
- Zeranol, estradiol, estriol, and estrone were successfully identified as azo dyestuffs.
Conclusions:
- The coupling of hormones with Fast Dark Blue R Salt provides an improved, sensitive detection method.
- This method is suitable for monitoring hormone residues in food products.
- Analytical techniques like TLC are effective for identifying specific hormone residues.
