In the process of synthesis of magnesium pyruvate, as the source of magnesium, its purity directly affects the final quality of magnesium pyruvate. The higher the purity, the fewer impurities generated in the reaction, thereby improving the purity, solubility and bioavailability of the product. The following aspects explain the impact of magnesium oxide purity on the quality of magnesium pyruvate in detail:
1. Problems caused by low-purity magnesium oxide
If low-purity magnesium oxide is used (such as industrial or low-grade food grade), the following problems may occur:
Impurities affect chemical reactions: Low-purity magnesium oxide may contain impurities such as silicon (Si), iron (Fe), aluminum (Al), etc. These impurities may interfere with the complexation reaction between pyruvate and magnesium ions and affect product quality.
Reduce the solubility of magnesium pyruvate: Magnesium oxide with lower purity may form some insoluble by-products, such as magnesium carbonate (MgCO₃) or magnesium hydroxide (Mg(OH)₂), reducing the water solubility of the final product and affecting the body’s absorption.
Influence of bioavailability: Magnesium pyruvate with more impurities may lead to uneven release of magnesium ions, reducing its absorption rate in the body, and affecting the effect of supplementing magnesium.
Safety issues: If magnesium oxide contains heavy metals (such as lead, cadmium, arsenic, etc.), it may pose a threat to human health, especially if taken for a long time.
2. Advantages of high-purity magnesium oxide
Synthesis of magnesium pyruvate using high purity (≥98%) magnesium oxide has the following advantages:
Improve reaction efficiency: High-purity magnesium content of magnesium is higher, and it can react with pyruvate more effectively, improving yield and reaction speed.
Ensure product purity: Avoid the introduction of impurities, improve the purity of magnesium pyruvate, and make it meet medical or food standards.
Enhance solubility and bioavailability: Magnesium pyruvate with higher purity is easier to dissolve in water, improving its absorption and metabolic efficiency in the human body.
Improve safety: Low heavy metal content, ensure product safety, and comply with food and medicine regulations.
3. Quality control and testing
In order to ensure the quality of magnesium pyruvate, the purity of magnesium oxide should be tested during the production process, including:
X-ray fluorescence spectroscopy (XRF) – used to detect elemental composition in magnesium oxide and evaluate impurity content.
Atomic Absorption Spectroscopy (AAS) – Used to detect heavy metal content to ensure compliance with food or pharmaceutical standards.
Titration – Determine the content of magnesium oxide to ensure the accuracy of the magnesium source.
Solubility Test – Evaluate the solubility of magnesium oxide at different pH environments to ensure it can be converted to magnesium pyruvate efficiently.
