ISO 20647 Vitamin A Testing in Infant Formula
The importance of accurate and reliable testing cannot be overstated when it comes to ensuring the safety and quality of infant formula. ISO 20647 specifically addresses this need by providing a standardized method for determining the vitamin A content in infant formula products. This service is crucial not only for manufacturers aiming to comply with international standards but also for regulatory bodies tasked with overseeing food safety.
The testing process under ISO 20647 involves several steps, each designed to ensure that the results are accurate and consistent. The first step is the preparation of the sample, which typically involves diluting a portion of the infant formula in a solvent. This dilution ensures that the vitamin A concentration falls within the linear range of the analytical method used.
The next step is the extraction of vitamin A from the sample. This can be achieved through various means depending on the specific requirements and capabilities of the laboratory. Common methods include liquid-liquid extraction or solid-phase extraction, both of which are designed to selectively extract vitamin A while minimizing interference from other components in the sample.
After extraction, the sample is analyzed using high-performance liquid chromatography (HPLC) with photodiode array detection and tandem mass spectrometry. This combination allows for precise quantification of vitamin A, ensuring that even trace amounts are accurately measured. The method used is based on the characteristic ion fragmentation patterns observed in the mass spectrum.
The accuracy and precision of this testing process are critical to ensure that infant formula meets the strict requirements set forth by ISO 20647. The standard specifies a target range for vitamin A content, which must be adhered to within ±15% of the stated value on the product label. This ensures consistency across different batches and helps maintain consumer trust.
Compliance with this standard is not just about meeting regulatory requirements; it also has broader implications for public health. Ensuring that infant formula contains the correct amount of vitamin A can prevent deficiencies, which are especially critical during early stages of life when growth and development are rapid. Inadequate levels of vitamin A can lead to conditions such as night blindness or impaired immune function.
For manufacturers, this service provides a competitive edge by demonstrating commitment to quality and safety. It also helps in maintaining a strong brand reputation, which is vital in the infant formula market where trust plays a significant role. For regulatory bodies, adherence to ISO 20647 ensures that products on the market are safe and effective.
The testing process under ISO 20647 is not without its challenges. One of the main hurdles is ensuring that all steps in sample preparation and analysis are meticulously followed. Even small deviations can lead to inaccuracies, which could have serious consequences for both manufacturers and consumers. To mitigate these risks, laboratories must invest in robust quality control processes and continuous training for their staff.
In conclusion, ISO 20647 Vitamin A Testing in Infant Formula is a vital service that ensures the safety and quality of infant formula products. By adhering to this standard, manufacturers can meet regulatory requirements while also contributing to public health by preventing vitamin deficiencies. This testing process is complex but essential for maintaining high standards in infant nutrition.
Applied Standards
The ISO 20647 standard specifically addresses the determination of vitamin A content in infant formula products. It provides a detailed protocol that laboratories must follow to ensure accurate and consistent results. The standard is widely recognized and used globally, making it an essential tool for quality management and compliance officers.

The application of this standard ensures that all testing processes are standardized, reducing the risk of variability between different laboratories. This consistency is crucial for maintaining the integrity of test results and ensuring that they can be relied upon by both manufacturers and regulatory bodies.
Compliance with ISO 20647 helps in minimizing the potential for errors or inconsistencies in vitamin A content measurement. By adhering to this standard, laboratories demonstrate their commitment to quality and reliability, which is particularly important given the critical role that infant formula plays in early childhood nutrition.
Scope and Methodology
The scope of ISO 20647 Vitamin A Testing in Infant Formula encompasses the determination of vitamin A content within the specified range for infant formula products. The method is designed to be accurate, precise, and reproducible, ensuring that results are consistent across different batches and laboratories.
The methodology involves several key steps: sample preparation, extraction, analysis, and quantification. Each step must be carefully executed to ensure the integrity of the final result. Sample preparation begins with the dilution of a portion of infant formula in a suitable solvent. This step ensures that the vitamin A concentration is within the linear range of the analytical method.
Extraction follows sample preparation, where vitamin A is selectively extracted from the sample using liquid-liquid or solid-phase extraction techniques. The choice of technique depends on the specific requirements and capabilities of the laboratory. Once extracted, the sample undergoes analysis using high-performance liquid chromatography (HPLC) with photodiode array detection and tandem mass spectrometry.
The HPLC system is equipped with a diode-array detector that allows for the identification of vitamin A based on its characteristic absorption spectrum. The tandem mass spectrometer further confirms the identity by analyzing the fragmentation patterns of the extracted compounds. This dual approach ensures both sensitivity and specificity, allowing even trace amounts of vitamin A to be accurately quantified.
The final step in the methodology is quantification. This involves comparing the signal intensity from the HPLC-MS/MS analysis to a calibration curve prepared using known concentrations of vitamin A standards. The concentration of vitamin A in the infant formula sample is then calculated based on this comparison. The result must fall within the target range specified by ISO 20647, which is ±15% of the stated value on the product label.
To ensure consistency and reliability, laboratories should follow strict quality control procedures throughout the testing process. This includes regular calibration of instruments, validation of methods, and participation in proficiency testing programs. By adhering to these practices, laboratories can maintain high standards of accuracy and precision in their vitamin A testing.
