CFR 21 Mineral and Ion Content Testing in Food Contact Substances
The U.S. Code of Federal Regulations (CFR) Title 21, Part 175-189 outlines the requirements for food contact substances used in packaging, containers, and processing aids that come into direct or indirect contact with foods. These regulations aim to ensure that such materials do not contaminate food products with harmful levels of contaminants, including metals like lead, cadmium, arsenic, and other ions.
Mineral content testing under CFR 21 is crucial for ensuring the safety and compliance of food contact substances (FCS). This service involves analyzing the ion and mineral content to ensure that the substance does not leach harmful amounts into the food. Regulatory limits are set by agencies such as the U.S. Food & Drug Administration (FDA) based on scientific data and risk assessments.
The testing process typically includes sample preparation, dissolution of the material, and then analysis using advanced instrumentation like inductively coupled plasma mass spectrometry (ICP-MS) or atomic absorption spectroscopy (AAS). These techniques provide precise measurements for trace elements down to parts per billion levels. The goal is to ensure that the FCS complies with the maximum allowable limits set forth by CFR 21.
Compliance testing under this regulation ensures not only safety but also consumer trust and regulatory compliance. Non-compliance can lead to significant legal, financial, and reputational risks for manufacturers. This service is essential for quality managers, R&D engineers, and compliance officers who are responsible for ensuring that food contact substances meet the required standards.
Here’s a breakdown of the key minerals typically tested:
- Pb (Lead)
- Cd (Cadmium)
- Hg (Mercury)
- Cr (Chromium)
- As (Arsenic)
- F (Fluoride)
The testing process ensures that the FCS do not exceed the maximum limits set by CFR 21. For instance, Pb and Cd have strict limits to prevent neurotoxic effects in humans.
Benefits
Complying with CFR 21 is critical for food manufacturers and processors as it ensures that the materials used do not introduce harmful levels of metals or other ions into the food supply. This compliance not only protects public health but also helps in avoiding legal issues, product recalls, and potential damage to brand reputation.
Our testing service provides several benefits:
- Ensures regulatory compliance with CFR 21
- Reduces the risk of product recalls and associated costs
- Aids in maintaining consumer trust by ensuring safe food contact materials
- Provides data that supports marketing claims about safety and quality
The accurate testing ensures that your products meet all regulatory requirements, thus protecting both the manufacturer’s reputation and public health.
