Extraction and Processing

Stevia is a natural sweetener derived from the leaves of the Stevia rebaudiana plant. The sweet-tasting components, known as steviol glycosides, are extracted and processed to create various forms of stevia products, such as powders and liquid substances.

The extraction process begins by crushing the stevia leaves and steeping them in hot water to release the steviol glycosides, which include rebaudioside A, one of the most abundant and sweetest glycosides found in the plant. This liquid extract is then filtered to separate the glycosides from the leaves and any impurities.

Crude stevia extracts undergo further purification processes to achieve high-purity steviol glycosides. This typically involves the use of water and/or food-grade alcohol to eliminate undesirable compounds and enhance the sweetness profile. The alcohol, if used, is removed before the product is finalized.

The resulting high-purity steviol glycosides can be further processed into various forms, such as powders or liquids, depending on their intended use. Powdered stevia is often blended with a filler, like fructooligosaccharides (FOS), which is a plant-based fiber, to improve the product’s texture and usability.

It’s essential to note that food-grade stevia leaf extract must have at least 95% steviol glycosides to be considered suitable for consumption. This standard is upheld in the majority of countries where stevia leaf extract is sold and ensures a consistent, high-quality product.

In summary, the extraction and processing of stevia involve water extraction, filtration, purification, and product formulation to provide consumers with a natural, safe, and versatile sweetener option.
