Onion (Allium cepa) Herbal Extraction Plant
- Raw Material Selection: Fresh and mature red or white onions are sourced from reliable farms. The selected onions are rich in quercetin, sulfur compounds, flavonoids, and antioxidants, which form the key constituents of the extract.
- Cleaning and Preparation: The onions are thoroughly washed in clean water to remove dirt and impurities. Outer dry skins and inedible parts are peeled off using automated peeling systems.
- Extraction Process: The crushed onion mass is transferred to the extractor, where hydro-alcoholic solvents (ethanol or water-ethanol mixture) are used for the extraction process. The mixture is gently heated to extract maximum bioactives without degrading the thermolabile components.
- Filtration and Concentration: Post extraction, the slurry is passed through filters to separate solid residues from the liquid extract.
- Standardization: The extract is standardized to contain a specific percentage of quercetin or sulfur compounds, ensuring consistent efficacy across batches.
- Packaging and Storage: Final onion extract is packed in light-resistant, airtight containers and stored in cool, dry conditions to maintain its stability and bioactivity.
