ISO 21033 Vitamin D Determination in Premix Samples
The determination of vitamin D content in premix samples is critical for ensuring consistent product quality and safety. ISO 21033 provides a standardized method that helps laboratories achieve precision, accuracy, and reliability in the analysis of vitamin D levels in feed additives.
Vitamin D plays a vital role in bone health and immune function; its presence at optimal levels ensures that animals consuming these premixes are healthy. The ISO 21033 protocol is designed to be robust enough to handle various sample matrices, including complex mixtures of nutrients found in feed additives.
The method involves the extraction of vitamin D from the premix sample followed by derivatization with a reagent that enhances detection sensitivity. After derivatization, the sample is analyzed using high-performance liquid chromatography (HPLC) coupled with ultraviolet-visible (UV-Vis) or fluorescence detection. This approach ensures accurate quantification even at low concentrations.
One of the key challenges in this analysis is the potential interference from other components present in the feed premix, which can vary widely depending on formulation and source materials. To address this issue, the ISO 21033 protocol includes several steps to minimize such interferences through sample preparation techniques like solid-phase extraction (SPE).
Another important aspect of this service is the ability to handle different types of premix samples, ranging from simple blends to highly complex formulations. Our laboratory ensures that each sample receives individual attention and appropriate handling protocols tailored specifically for its composition.
The ISO 21033 protocol also allows for the determination of total vitamin D content as well as specific forms such as cholecalciferol (vitamin D3) and ergocalciferol (vitamin D2). This versatility makes it suitable not only for quality control purposes but also for research into new formulations or modifications aimed at improving nutritional profiles.
Our commitment to excellence extends beyond just meeting the requirements of ISO 21033. We strive to provide timely results, ensuring that our customers can make informed decisions promptly based on reliable data provided by our analyses.
Applied Standards
The ISO 21033 protocol is widely recognized for its accuracy and reliability in determining vitamin D content in feed additives. It has been adopted globally as the preferred method due to its comprehensive approach which covers all aspects from sample preparation through final analysis.
This standard specifies clear procedures that must be followed during each step of the process, thereby reducing variability between laboratories performing this type of analysis.

Use Cases and Application Examples
| Application Scenario | Objective |
|---|---|
| Determining compliance with feed additive specifications. | To ensure that the vitamin D content in premixes meets regulatory standards set by organizations like FDA or EU Commission. |
| Evaluating efficacy of newly developed vitamin D supplements for animal nutrition. | To assess whether the new formulation provides sufficient amounts of vitamin D to support healthy bone growth and development. |
| Monitoring changes in vitamin D levels during production processes. | To track any fluctuations that could indicate issues with manufacturing methods or raw material sourcing. |
| Comparing different suppliers' products for quality assurance purposes. | To identify the most reliable supplier based on consistent performance over multiple batches and lots. |
In addition to these applications, the ISO 21033 method can also be used during troubleshooting when unexpected results are observed. It allows for detailed investigation into possible causes such as contamination or improper storage conditions which might affect vitamin D stability within premixes.
