Overview

The BS EN ISO 15151:2020 is a comprehensive standard that provides a detailed methodology for the determination of minerals and trace elements in milk, milk products, infant formula, and adult nutritionals. This standard utilizes the advanced technique of Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) to ensure precise and accurate results.

Why Choose BS EN ISO 15151:2020?

In the world of food safety and quality assurance, the accurate determination of mineral content is crucial. This standard is designed to meet the needs of laboratories and manufacturers who require reliable and consistent methods for analyzing the mineral and trace element content in dairy and nutritional products. Here are some reasons why this standard is essential:

• Precision and Accuracy: The ICP-AES method is renowned for its ability to provide precise and accurate measurements, making it ideal for the analysis of complex matrices such as milk and nutritional products.
• Comprehensive Coverage: This standard covers a wide range of products, including milk, milk products, infant formula, and adult nutritionals, ensuring its applicability across various sectors of the food industry.
• International Recognition: As an ISO standard, it is recognized and respected globally, facilitating international trade and compliance with regulatory requirements.

Applications

The BS EN ISO 15151:2020 standard is applicable in various settings, including:

• Food Testing Laboratories: Laboratories that specialize in food safety and quality testing can utilize this standard to ensure the accuracy of their mineral content analyses.
• Dairy Industry: Dairy producers can use this standard to verify the mineral content of their products, ensuring they meet nutritional labeling requirements and quality standards.
• Infant Formula Manufacturers: Ensuring the correct mineral content in infant formula is critical for the health and development of infants. This standard provides a reliable method for such determinations.
• Regulatory Bodies: Government and regulatory agencies can use this standard as a benchmark for setting and enforcing food safety regulations.

Technical Details

The ICP-AES method described in this standard involves the use of an inductively coupled plasma to excite atoms and ions in a sample. The emitted light is then measured to determine the concentration of specific elements. This technique is particularly effective for detecting trace elements due to its high sensitivity and ability to handle complex sample matrices.

Benefits of Using ICP-AES

Inductively Coupled Plasma Atomic Emission Spectrometry offers several advantages:

• High Sensitivity: Capable of detecting elements at very low concentrations, making it ideal for trace element analysis.
• Multi-Element Capability: Allows for the simultaneous determination of multiple elements, increasing efficiency and reducing analysis time.
• Robustness: Suitable for a wide range of sample types, including those with complex matrices like milk and nutritional products.

Conclusion

The BS EN ISO 15151:2020 standard is an essential tool for anyone involved in the analysis of minerals and trace elements in dairy and nutritional products. Its use of the ICP-AES method ensures that results are both accurate and reliable, providing confidence in the quality and safety of the products being tested. Whether you are a laboratory technician, a dairy producer, or a regulatory official, this standard is a valuable resource for ensuring compliance with industry standards and regulations.

This standard BS EN ISO 15151:2020 Milk, milk products, infant formula and adult nutritionals. Determination of minerals and trace elements. Inductively coupled plasma atomic emission spectrometry (ICP-AES) method is classified in these ICS categories:

• 67.100.10 Milk and processed milk products

This document specifies a method for the quantitative determination of calcium (Ca), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), phosphorus (P), potassium (K), sodium (Na) and zinc (Zn) using inductively coupled plasma atomic emission spectrometry (ICP-AES). The method is applicable for milk, dried milk, butter, cheese, whey, dried whey, infant formula and adult nutritional formula in the ranges given in Table 1.

Table 1

Analytical ranges

	Ca	Cu	Fe	Mg	Mn	P	K	Na	Zn
Lower analytical rangea, in mg/100 g	20	0,03	0,5	3	0,01	15	10	10	0,2
Upper analytical rangea, in mg/100 g	1 280	1,2	20	110	1,0	800	2 000	850	18

^a concentrations apply to

— milk and “ready-to-feed” liquids as-is, using a typical sample size of 4 g per final analytical solution volume of 25 ml and

— reconstituted milk powder, infant formula powders and adult nutritional powders (25 g into 200 g of water), using a typical sample size of mass of the reconstituted slurry per final analytical solution volume of 25 ml.

Ranges for non-reconstituted dairy ingredients (butter, cheese, whey powders, whey protein concentrates) are adjusted proportionally upward from these values based upon the sample size used for the ingredient. For example, if 0,6 g of cheese is digested the ranges will be 4 g/0,6 g = 6,7 × higher.
