ISO 16050 Aflatoxin Detection in Food Products by HPLC
The presence of aflatoxins in food and feed products poses significant health risks, particularly to populations that consume large quantities of these commodities. ISO 16050 provides a standardized method for the determination of aflatoxins (B1, B2, G1, and G2) in food products by high-performance liquid chromatography (HPLC). This service ensures accurate, reliable, and reproducible results that are essential for regulatory compliance.
The process begins with the selection of appropriate sample matrices. Common food items such as corn, peanuts, rice, and tree nuts require specific handling to prevent contamination during extraction. Extraction solvents like acetonitrile or methanol are used in conjunction with sonication or ultrasonic baths to ensure thorough dissolution of aflatoxins.
After extraction, the samples undergo cleanup using solid-phase extraction (SPE) cartridges. These cartridges help remove interfering compounds that could affect chromatographic performance. Post-extraction, the clean extracts are injected into the HPLC system equipped with a fluorescence detector optimized for detecting aflatoxins. This setup allows for precise quantification based on calibration curves prepared from known standards.
The method's sensitivity is enhanced by employing post-column derivatization techniques when necessary. These steps ensure that even trace amounts of aflatoxins are detectable, which is crucial given the strict regulatory limits set forth by international organizations like the World Health Organization (WHO) and Food and Agriculture Organization of the United Nations (FAO).
Results obtained from this method are reported in terms of parts per billion (ppb), aligning with global standards. Compliance reports include detailed information about sample preparation, chromatographic conditions, and detected concentrations of aflatoxins.
This service plays a pivotal role in safeguarding public health by identifying potentially harmful levels of aflatoxins before they reach consumers. It supports various stakeholders including manufacturers, distributors, and regulators who rely on accurate data for decision-making processes related to product safety.
| Sample Matrix | Possible Interferents | Cleanup Method | Detection Limit (ppb) |
|---|---|---|---|
| Corn | Myricetin, Quercetin | SPE Cartridge | 0.1 |
| Peanuts | Rutin, Kaempferol | SPE Cartridge | 0.2 |
| Rice | Vitamin E | SPE Cartridge | 0.3 |
| Tree Nuts | Catechin, Epicatechin | SPE Cartridge | 0.15 |
The use of this method ensures consistency across different laboratories performing similar analyses, thereby enhancing confidence in the results.
Applied Standards
The ISO 16050 standard is widely recognized and adopted globally for its robustness and accuracy. It specifies the procedure for determining aflatoxins (B1, B2, G1, and G2) in food products using HPLC with fluorescence detection. This standard is crucial because it provides a harmonized approach to aflatoxin analysis, ensuring comparability of results across different laboratories.
The method described in ISO 16050 addresses the need for precise quantification of these harmful compounds, which are known carcinogens and mutagens. By adhering strictly to this standard, our laboratory guarantees compliance with international regulatory requirements set by bodies such as WHO, FAO, and various national food safety authorities.
The application of ISO 16050 not only ensures accurate measurement but also contributes to the overall quality control framework within industries dealing with high-risk commodities. This includes agribusinesses, pharmaceutical companies involved in herbal medicine production, and research institutions conducting studies on mycotoxin exposure.
Industry Applications
Aflatoxins are particularly problematic in agricultural products like corn, peanuts, rice, and tree nuts. Their presence can lead to severe health issues including acute toxicity, immunosuppression, and even cancer if ingested over extended periods.
- Corn: Aflatoxin contamination is common due to fungal infection during storage or post-harvest handling.
- Peanuts: Susceptible to mold growth under humid conditions, leading to aflatoxin accumulation.
- Rice: Can be contaminated through soil contamination or improper drying practices.
- Tree Nuts: Vulnerable during processing and packaging stages if not handled correctly.
The ISO 16050 HPLC method is vital in these sectors to monitor and control aflatoxin levels. Regular testing helps prevent contamination, ensures product safety, and maintains consumer trust. By adhering to this standard, companies can meet stringent regulatory requirements imposed by national governments and international trade agreements.
Customer Impact and Satisfaction
