How XRF is Used for Food Analysis

XRF analyzers are widely used in the food industry for quality control and safety assurance ???. Our analyzers can determine the content of heavy metals such as lead, cadmium, and mercury in food products. This allows manufacturers and regulators to confidently ensure their products comply with international standards and regulations ??.

Additionally, our XRF analyzers can be used to monitor the mineral composition of food products ??. This is important not only for safety but also for maintaining the nutritional value of the food. For instance, dairy products can be analyzed for calcium and other essential minerals, helping to guarantee their quality and adherence to declared characteristics ??.

Advantages of Using XRF for Food Analysis

• Speed and Efficiency ?? XRF allows for rapid analysis results, which is crucial in production environments and for making quick decisions.
• Simplified Sample Preparation ?? Samples for XRF analysis require minimal preparation, simplifying the process and reducing the costs associated with preparatory procedures.
• High Accuracy and Reproducibility ?? XRF provides high accuracy and reproducibility of results, ensuring reliable data for informed decision-making.
• Non-Destructive Testing ??? XRF enables the analysis of products without damaging them, important for verifying the quality of finished products while preserving their commercial value.

Regulation (EU) 2023/915 on Maximum Levels of Contaminants in Food

In Europe, the regulation of chemical elements in food is governed by various legislative acts, including Regulation (EU) 2023/915 ??. This regulation sets maximum levels for specific contaminants in food products to protect the health of EU citizens, including children and pregnant women ????. Its main goal is to minimize consumer exposure to harmful chemicals.

The regulation covers a wide range of contaminants, including mycotoxins, metals, plant toxins, and other chemical elements ??. Products with contaminant levels exceeding the set limits cannot be sold in the EU market, ensuring high safety and quality standards for food products ??.

Examples of Specific Limits for Elements like Lead, Cadmium, and Mercury

Under Regulation (EU) 2023/915, strict limits are set for heavy metals in food products:

• Lead: Maximum levels vary depending on the type of product. For example, in vegetables and fruits, the maximum level is 0.10 mg/kg, while in cereal products, it is 0.20 mg/kg ??.
• Cadmium: Maximum levels for cadmium range from 0.02 mg/kg to 0.1 mg/kg depending on the product type. For instance, for vegetables and fruits, this limit is 0.05 mg/kg ??.
• Mercury: Maximum levels for mercury also depend on the product type. In fish and seafood, this limit is 0.5 mg/kg ??.

U.S. Legislation and Standards: The Role of the EPA and FDA

In the United States, the control of chemical elements in food products is regulated by several agencies ????. The Environmental Protection Agency (EPA) plays a key role in setting allowable levels of pesticides and heavy metals in food. The EPA develops and implements regulations known as Tolerance Levels, which describe the maximum amount of pesticide residues legally permissible in or on food products ??.

These allowable levels are developed based on rigorous scientific research to ensure consumer protection ??. Including heavy metals in EPA regulations aims to prevent the accumulation of harmful substances in the human body through food chains ???.

The Food and Drug Administration (FDA) also plays an important role in ensuring food safety ???. The FDA establishes permissible levels of various chemical contaminants, including heavy metals and toxins, and checks compliance with these levels through monitoring and control programs ????. One such program is the Total Diet Study, which regularly analyzes food samples for various chemical elements, including metals.

The FDA works closely with the EPA to ensure a comprehensive approach to food quality and safety control ???. This includes regularly updating standards and regulations based on the latest scientific data and research ??.

Specific Limits for Elements like Lead and Cadmium

To ensure consumer safety, the FDA and EPA have set strict standards for heavy metals in food products:

• Lead: Maximum levels for lead in food products vary depending on the type of product. For example, in baby foods, the permissible lead level is 0.01 mg/kg, while in other products it can be up to 0.1 mg/kg ??.
• Cadmium: Permissible levels for cadmium also depend on the product category. In most food products, the maximum cadmium level is 0.2 mg/kg ??.

These standards aim to ensure consumer safety, minimize the risk of adverse effects from chemical elements, and maintain high standards of food quality ??.

Determining Heavy Metals in Compliance with European and American Standards

One of the key tasks in ensuring food safety is controlling the content of heavy metals such as lead, cadmium, and mercury ??. Both Europe and the U.S. have established strict standards regulating the permissible levels of these elements in food products. Using XRF analyzers allows for the precise and rapid determination of heavy metals in food products, ensuring compliance with international standards ??.

For example, in the production of baby food or dairy products, it is crucial to monitor the minimal content of lead and cadmium to avoid negative impacts on children's health ??. Elvatech's XRF analyzers provide the capability for non-destructive testing, enabling quality control at every stage of production and distribution ??.

Monitoring Mineral Composition in Food Products

In addition to controlling contaminants, XRF analyzers are widely used to determine the mineral composition of food products ??. Minerals play an important role in nutrition, and their content must meet declared quality standards ??. For instance, dairy products are often analyzed for calcium, magnesium, and other essential minerals ??.

Our benchtop analyzers, such as the ElvaX Pro, equipped with a 16-position carousel, are ideal for conducting such analyses in laboratory settings ??. This equipment ensures high productivity and precision, allowing for the analysis of a large number of samples in a short time ??.
