USP Aflatoxin Detection in Peanut Products
The United States Pharmacopeia (USP) standard is a critical guideline for the detection of aflatoxins, particularly in peanut products. Aflatoxins are potent toxins produced by certain molds and can be hazardous to human health if present at levels above safe limits. This service ensures compliance with USP standards, which are widely recognized globally.
The process begins with sample collection from the source or manufacturing facility. Peanut samples must be representative of the batch being tested to ensure accurate results. Once collected, these samples undergo rigorous preprocessing steps, including grinding and homogenization, to achieve a consistent particle size for uniform extraction.
After preparation, the sample is subjected to an analytical procedure that involves liquid chromatography with fluorescence detection (LC-FLD). This technique offers high sensitivity and specificity, making it ideal for detecting trace amounts of aflatoxins. The method follows USP guidelines meticulously.
The LC-FLD system is equipped with a column optimized for aflatoxin separation. Post-column derivatization ensures that the aflatoxins are detected efficiently, even in complex matrices like peanut products. Calibration using authentic standards guarantees accurate quantification of the toxins present.
Results are reported based on USP limits, ensuring compliance with regulatory requirements. Compliance officers and quality managers can use these results to ensure their products meet safety standards before being marketed or sold.
The precision and accuracy of this method make it suitable for both routine testing and research purposes within the food industry. R&D engineers benefit from this service as they strive to develop safer, more reliable products. Procurement teams can rely on these test results to source peanuts that meet stringent safety criteria.
Compliance with USP standards is essential in maintaining a high level of product safety and quality. Our laboratory adheres strictly to these guidelines, providing accurate and timely results. By choosing this service, stakeholders ensure their products are safe for consumption and adhere to international health regulations.
Applied Standards
The USP standard for aflatoxin detection in peanut products is based on liquid chromatography with fluorescence detection (LC-FLD). This method has been validated and standardized by the United States Pharmacopeial Convention Inc. to ensure consistent and accurate results.
The standard specifies a lower limit of quantitation (LoQ) for aflatoxins, typically set at 1 ppb or less, depending on the specific type of aflatoxin being tested. This ensures that even trace amounts are detected accurately. The method also includes calibration using authentic standards to ensure precision and accuracy.
Compliance with USP is crucial for ensuring product safety and quality. The standard is regularly updated based on the latest scientific research and regulatory requirements, making it a reliable benchmark for aflatoxin detection in food products.
Scope and Methodology
The scope of our USP service covers all peanut products, including raw peanuts, roasted peanuts, peanut butter, and other processed forms. This comprehensive coverage ensures that every potential source of aflatoxin contamination is addressed.
The methodology begins with sample preparation, which involves grinding the samples to a consistent particle size. This step is crucial for ensuring uniform extraction and accurate analysis. After preparation, the samples are analyzed using LC-FLD, as specified in USP . The system includes post-column derivatization, which enhances detection sensitivity.
The calibration process uses authentic aflatoxin standards to ensure that the method is precise and accurate. This step is critical for obtaining reliable results that can be used to determine compliance with regulatory limits. Once calibrated, the instrument is ready for analysis of actual samples.
Results are reported based on USP guidelines, providing a clear and consistent approach to quantifying aflatoxins in peanut products. This ensures that stakeholders have confidence in the results and can use them effectively for decision-making purposes.
