ISO 27656 Mercury Analysis in Baby Foods
The analysis of mercury in baby foods is a critical aspect of ensuring infant and young child nutrition safety. This service, based on ISO 27656, aims to quantify the presence of total mercury (Hg) in various forms within baby food products such as infant formulas, cereals, and other complementary feeds. The standard is essential for regulatory compliance and consumer trust.
Mercury can be present in baby foods due to environmental contamination or during processing. High levels of mercury are particularly concerning for infants and young children because their nervous systems are still developing. Therefore, accurate and reliable testing methods are necessary to ensure product safety.
The ISO 27656 standard provides a robust methodology for the determination of total mercury in baby foods by atomic absorption spectrometry (AAS) with a cold vapor generation (CVG). This technique is preferred due to its precision, accuracy, and ability to detect low levels of mercury. The test procedure involves several steps:
- Sample preparation: Samples are homogenized and diluted as necessary.
- Digestion: Digestion is carried out using nitric acid to break down the sample matrix.
- Vaporization: Mercury is converted into its atomic form for measurement.
- Spectrophotometric analysis: The absorbance of mercury atoms at a specific wavelength is measured.
The analytical process is stringent, with strict quality control measures ensuring results are accurate and reproducible. This includes using certified reference materials to calibrate the instrument and validating the method against known standards. The service also offers comprehensive reporting that includes detailed analysis parameters, detection limits, and comparison to relevant international standards such as ISO 27656.
Our laboratory adheres to strict protocols to ensure compliance with local and international regulations. This includes participating in proficiency testing programs organized by recognized bodies like the Codex Alimentarius Commission (CAC). Compliance is crucial for maintaining market access and consumer confidence. Our team of experts ensures that every batch of baby food undergoes rigorous testing, providing peace of mind to manufacturers and parents alike.
The significance of this service extends beyond just regulatory compliance. By adhering to ISO 27656 standards, we support the development of safe and nutritious products for infants and young children. This aligns with global initiatives aimed at protecting vulnerable populations from harmful contaminants. The results of our testing are essential inputs for quality managers, compliance officers, R&D engineers, and procurement teams who rely on accurate data to make informed decisions.
Scope and Methodology
The ISO 27656 standard defines the scope and methodology for analyzing total mercury in baby foods. The procedure focuses on detecting both elemental (Hg0) and organic forms of mercury, including methylmercury (CH3Hg+), ethylmercury (C2H5Hg+), and dimethylmercury (Hg(C2H5)2). This comprehensive approach ensures that all potentially harmful forms of mercury are identified.
The methodology involves several key steps:
- Sample selection: Representative samples must be selected from batches or lots to ensure statistical significance.
- Preparation: Samples undergo thorough preparation, including homogenization and dilution if necessary.
- Digestion: Nitric acid is used for digestion of the sample matrix.
- Vaporization: Mercury species are converted into their atomic forms using CVG technology.
- Spectrophotometric analysis: The absorption spectra of mercury atoms are analyzed at a specific wavelength.
The process ensures that all relevant forms of mercury are quantified accurately. The use of AAS with CVG is preferred due to its high sensitivity and selectivity, making it ideal for detecting even trace amounts of mercury in complex matrices like baby food.
Quality control measures include the use of standard reference materials and inter-laboratory comparisons to ensure consistency and accuracy across different batches. Our laboratory personnel are trained professionals who follow strict protocols to maintain the integrity of the testing process. This includes regular calibration of instruments, validation against known standards, and adherence to international guidelines.
The results generated from this analysis provide valuable information for manufacturers and regulatory bodies. These data can inform product development, production processes, and labeling requirements. By adhering strictly to ISO 27656, we contribute to the overall safety and quality of baby food products, ensuring that they meet or exceed international standards.

This ensures that test results obtained from our laboratory are universally accepted, facilitating seamless trade across borders. Compliance with this standard is essential not only for maintaining market access but also for ensuring consumer trust.
- Regulatory Compliance: Many countries have adopted ISO 27656 as a benchmark for regulatory compliance. This includes the European Union (EU), United States Food and Drug Administration (FDA), and World Health Organization (WHO).
- Market Access: Certification to this standard opens doors to international markets, ensuring that products meet stringent safety requirements.
- Consumer Trust: The use of internationally recognized standards builds trust among consumers who can be confident in the quality and safety of the products they purchase.
The global nature of ISO 27656 is reflected in its wide application across various regions. For instance, the European Union has incorporated this standard into its regulations for food safety, while the United States uses it as a reference for enforcing federal laws related to food and drug administration. Similarly, the World Health Organization recommends adherence to these guidelines when assessing the safety of infant formula and baby foods.
By adhering to ISO 27656, we not only meet domestic requirements but also align with international best practices. This alignment is crucial for ensuring that our testing services are accepted worldwide, thereby enhancing market access and consumer confidence. Our commitment to maintaining the highest standards of quality control and reliability ensures that every test performed contributes positively towards these goals.
