Aspalathus Linearis Extract is a naturally occurring compound derived from the plant of the same name belonging to the Fabaceae family also known by the name Rooibos.
Industrial Production Process
- Whole Plant Harvesting: The Aspalathus Linearis plant is harvested in the mountainous regions of South Africa, where it naturally grows. Harvesting is done manually to preserve the integrity of the plant and ensure the quality of the collected material.
- Drying: After harvesting, the whole plant undergoes a drying process, either sun-dried or using controlled dryers, to reduce moisture content and preserve the bioactive compounds.
- Extraction: The dried plant is then ground and subjected to an extraction process. This can be achieved using hot water or solvents such as ethanol, depending on the specific properties desired in the final extract and its intended use.
- Concentration and Purification: The obtained extract is concentrated under vacuum and purified to remove any impurities and residual solvents, thus obtaining a high-quality extract that maintains the integrity of the plant's bioactive compounds.
- Quality Control: The Aspalathus Linearis extract from the whole plant undergoes quality control checks to ensure the concentration of antioxidants, purity, and the absence of contaminants. These tests can include spectroscopic, chromatographic, and microbiological analyses.
