USDA Nutrient Data Laboratory Vitamin D Testing
The USDA Nutrient Data Laboratory (NDL) Vitamin D Testing service provides precise and reliable quantification of vitamin D content in food and feed samples. This testing is crucial for ensuring compliance with regulatory standards, supporting product safety, and meeting consumer expectations regarding dietary health.
At its core, the NDL's expertise lies in nutrient analysis using validated methods that align with international standards such as ISO, ASTM, EN, IEC, and the US Pharmacopeial Convention (USP). The service covers a range of vitamin D forms including cholecalciferol (D3) and ergocalciferol (D2), which are essential for bone health and immune function.
The testing process involves several critical steps. Initially, samples undergo rigorous preparation to ensure accurate results. This includes homogenization, extraction using solvents like methanol or dichloromethane, and purification through column chromatography. The purified extracts are then analyzed via high-performance liquid chromatography (HPLC) coupled with ultraviolet detection.
Following analysis, the data is meticulously compiled into a report that includes quantification results along with detailed methodology descriptions. Compliance with regulatory requirements such as those set by the Food and Drug Administration (FDA) and Codex Alimentarius is guaranteed. This ensures that clients can confidently use the test results for product labeling, marketing claims, and quality assurance purposes.
The USDA NDL's Vitamin D Testing service is recognized internationally for its accuracy and reliability. The laboratory adheres to strict protocols ensuring that all tests meet or exceed international standards. This includes participation in proficiency testing programs organized by organizations such as the European Co-operation for Accreditation (EA).
For quality managers, compliance officers, R&D engineers, and procurement professionals, this service offers a comprehensive solution for ensuring the safety and efficacy of vitamin D content in food and feed products. It enables them to make informed decisions regarding product formulation, labeling, and regulatory compliance.
