Aspalathus Linearis Leaf 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
- Leaf Harvesting. Aspalathus Linearis leaves are harvested in the mountainous regions of South Africa, the only place where this plant naturally grows. Harvesting mainly occurs during the summer.
- Fermentation and Drying. After harvesting, the leaves undergo a natural fermentation process, exposing them to air for a period ranging from 12 to 24 hours. This process helps to develop the characteristic flavor and color of Rooibos. Subsequently, the leaves are sun-dried to stop the fermentation process.
- Extraction. The dried leaves are then ground and subjected to an extraction process using hot water or solvents such as ethanol, depending on the specific requirements of the final product. The extraction aims to isolate the bioactive compounds present in the leaves.
- 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.
- Quality Control. Before packaging, the Aspalathus Linearis leaf extract undergoes rigorous quality control checks to ensure the concentration of antioxidants, purity, and the absence of contaminants. These tests can include spectroscopic, chromatographic, and microbiological analyses.
