Comprehensive Guide to ISO 11206 Determination of Nitrite in Food by Colorimetric Method Laboratory Testing Service Provided by Eurolab
ISO 11206:2016 is the international standard for the determination of nitrite in food by colorimetric method. This standard is published by the International Organization for Standardization (ISO) and provides a method for the quantitative determination of nitrite in food products.
Legal and Regulatory Framework
The use of nitrite as a preservative in food products is regulated by various international and national authorities, including the European Commission, the US FDA, and the World Health Organization. These regulations aim to ensure the safety of consumers by limiting the amount of nitrite used in food production.
International and National Standards
Several standards govern the determination of nitrite in food, including:
Standard Development Organizations and Their Role
The development of standards is a collaborative effort between standard development organizations, such as ISO, ASTM, and EN. These organizations bring together experts from various industries to establish common methodologies for testing and evaluation.
Evolution and Updates of Standards
Standards evolve over time to reflect advances in technology and changes in regulatory requirements. The revision process involves revising the existing standard or developing a new one.
Specific Standard Numbers and Their Scope
ISO 11206:2016 specifies a colorimetric method for the determination of nitrite in food products, including meat, poultry, fish, and processed foods. The standard covers the sample preparation procedures, testing conditions, and measurement methods.
Standard Compliance Requirements for Different Industries
Compliance with ISO 11206:2016 is mandatory for industries that use nitrite as a preservative, such as:

Step-by-Step Explanation of How the Test is Conducted
1. Sample preparation: The sample is taken from the food product and prepared according to the standard.
2. Testing equipment: A colorimeter or spectrophotometer is used for the test.
3. Testing environment: The testing must be performed in a laboratory with controlled temperature, humidity, and lighting conditions.
4. Measurement method: The measurement is performed using a calibration curve.
Testing Equipment and Instruments Used
The standard specifies the use of a colorimeter or spectrophotometer for measuring the absorbance of the sample.
Sample Preparation Procedures
The sample must be prepared according to the standard by dissolving it in water, followed by dilution to achieve the required concentration.
Measurement and Analysis Methods
The measurement is performed using a calibration curve. The data is analyzed using statistical software to calculate the concentration of nitrite.
Calibration Curve
A calibration curve is created using standards of known concentrations of nitrite. The absorbance values are plotted against the concentrations, creating a linear relationship.
Testing Conditions
The testing must be performed in a laboratory with controlled temperature, humidity, and lighting conditions.
Measurement Precision and Accuracy
The standard requires that the measurement precision and accuracy meet specified limits to ensure reliable results.
Calibration of Equipment
The equipment used for the test must be calibrated regularly according to the manufacturers instructions. The calibration certificate is required for each test run.
Sample Identification and Labeling
The sample must be identified and labeled with its corresponding documentation, including batch number and concentration.
Testing Protocols and Procedures
The testing protocols and procedures are specified in the standard, which includes:
Measurement of Absorbance
The absorbance is measured using a calibration curve. The data is analyzed using statistical software to calculate the concentration of nitrite.
Calculation of Concentration
The concentration of nitrite is calculated from the absorbance values using the calibration curve.
Reporting Results
The results are reported in milligrams per kilogram (mg/kg) or parts per million (ppm).
Validation of Test Method
The test method must be validated according to the standard, which includes:
Quality Control Measures
Quality control measures are implemented to ensure that the testing meets the specified standards.
Training and Certification
Operators performing the test must undergo training and certification according to the standard.
Equipment Maintenance
The equipment used for the test must be maintained regularly according to the manufacturers instructions.
Documentation and Record-Keeping
All documentation, including sample identification, testing results, and quality control records, is required to be kept on file.
Reporting Results
The results are reported in milligrams per kilogram (mg/kg) or parts per million (ppm).
Limitations of Test Method
The test method has limitations that must be considered when interpreting the results. These include:
Interpretation of Results
The results are interpreted according to the standard, which includes:
Communication with Stakeholders
Results must be communicated to stakeholders, including regulatory agencies and industry partners.
Documentation and Record-Keeping
All documentation, including sample identification, testing results, and quality control records, is required to be kept on file.
Revision of Standard
The standard is revised periodically to reflect advances in technology and changes in regulatory requirements.
Conclusion
ISO 11206:2016 specifies a colorimetric method for the determination of nitrite in food products. This test is essential for ensuring consumer safety, regulatory compliance, and product quality. The testing must be performed by qualified personnel using calibrated equipment according to the standard.
