Resveratrol Powder Production Process
1. Raw material selection and pre-treatment
We select high-quality Polygonum cuspidatum roots as the raw materials, with the content of resveratrol strictly controlled at 5% or above. Our staff will thoroughly clean the raw materials, removing mud, sand and impurities, then dry them in a low-temperature environment, and finally crush the raw materials to 60-80 mesh, preparing them for the subsequent extraction process.
2. Extraction process (core steps)
We employ advanced supercritical CO₂ extraction technology, extracting under conditions of 25-35 MPa pressure and 40-50℃ temperature, with the CO₂ flow rate controlled at 20-30 L/h. This technology ensures that the resveratrol we extract has no solvent residues.
3. Purification and refinement
3. Purification and refinement
We use macroporous resin adsorption technology (AB-8 or HPD-100 resin) to purify the extract, using 30-50% ethanol as the eluent. To further enhance the purity, we will increase the purity of resveratrol to over 98% through low-temperature crystallization or molecular distillation processes.
4. Drying and Finished Product Formation
In the spray drying process, we strictly control the inlet temperature at 160℃ and the outlet temperature at 80℃, ultimately obtaining micron-sized high-quality resveratrol powder. Each batch of product undergoes HPLC testing for the content of trans-resveratrol and ensures that the indicators of heavy metals, microorganisms, etc. comply with EP/USP standards.
5. Packaging and Storage
We use aluminum foil bags for inner packaging and fill them with nitrogen to prevent oxidation. The outer packaging can be customized according to customer requirements. The standard packaging is 25kg per barrel. We recommend that customers store the products in a cool and dry place and avoid direct sunlight to ensure product stability.
