Functional Food & Beverage: Applied to health-focused food items such as protein powders and functional beverages as a natural antioxidant fortificant to improve nutritional profiles with clean-label appeal.

Production Process

Step 1 - Raw Material Selection: We get high-grade Sophora japonica flower buds from our certified organic planting base in Shaanxi Province, where agronomists supervise the growth conditions to guarantee optimal Kaempferol Powder concentration. Result: A better starting material with 15-20 percent more flavonoid concentration than wild obtained sources.

Step 2 - Cleaning & Preparation: Fresh or dried buds are mechanically cleaned, extraneous material is removed and milled to the right size in regulated processes. Result: Uniform particle distribution for optimal extraction efficiency.

Step 3 - Solvent Extraction: The raw materials are processed with food grade ethanol extraction under regulated temperature and pressure in our 100,000-level purification workshop. Crude extract at start with target chemicals and minimum heat degradation.

Step 4 - Filtration & Concentration: The extract is passed through multi-stage filtration systems and then vacuum concentrated to eliminate superfluous solvents and concentrate active components. Pre-purified concentrate ready for crystallisation.

Step 5 – Crystallisation & Purification: Kaempferol is precipitated out of the solution with careful controls of temperature and pH and then further undergoes recrystallisation cycles for pharma grade purity. Result: Crystals of high purity, ≥98% specification, yellow.
