Aspalathus Linearis /Stalk 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

• Harvesting of Leaves and Stalks. Leaves and stalks of Aspalathus Linearis are harvested in the mountainous regions of South Africa. Harvesting is done manually to preserve the integrity of the plant and ensure the quality of the collected material.
• Fermentation and Drying. After harvesting, the plant material undergoes a natural fermentation process, exposing it to air to allow the development of the characteristic flavor and color of Rooibos. It is then sun-dried to stop the fermentation process.
• Extraction. The dried leaves and stalks are 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.
• Concentration and Purification. The obtained extract is concentrated under vacuum and purified to remove any impurities and residual solvents, thus obtaining a concentrated and high-quality extract.
• Quality Control. The Aspalathus Linearis leaf and stalk extract 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.
