Organic Stevia rebaudiana extract, carbon dioxide extract.

Introduction to Stevia rebaudiana

Stevia rebaudiana is a remarkable plant that has a long - standing history of use. For centuries, it has been cherished for its sweet taste. Native to certain regions, this plant has found its way into the global spotlight in recent years due to its unique properties as a sweetener. The sweet taste of Stevia rebaudiana is not just a matter of coincidence but is a result of its chemical composition, which contains compounds that can provide a significant level of sweetness without the drawbacks associated with traditional sugars or artificial sweeteners.

The CO₂ Extraction Process

What is CO₂ Extraction?

Carbon dioxide extraction is a sophisticated method used to obtain the essence of Stevia rebaudiana. In this process, carbon dioxide is used in a supercritical state. A supercritical fluid has properties between those of a liquid and a gas. When carbon dioxide reaches its supercritical state, it can act as an excellent solvent for extracting the desired compounds from the Stevia rebaudiana plant. This is a very precise and efficient method as it can selectively target and extract the important components while leaving behind unwanted substances.

Advantages of CO₂ Extraction

• High - Quality Extract: The CO₂ extraction process ensures that the resulting Stevia rebaudiana extract is of a very high quality. It can precisely isolate the compounds responsible for the sweet taste, resulting in a more concentrated and pure extract.
• Environmentally Friendly: Compared to some other extraction methods, such as solvent - based extraction methods that may use chemicals that are harmful to the environment, carbon dioxide extraction is much more environmentally friendly. Carbon dioxide is a natural substance that is abundant in the atmosphere, and when used in the extraction process, it can be recycled easily, reducing waste and environmental impact.

Properties of the Organic Stevia rebaudiana CO₂ Extract

Steviol Glycosides - The Sweet Compounds

The organic Stevia rebaudiana CO₂ extract contains steviol glycosides, which are the key components responsible for its sweet taste. These glycosides are highly stable compounds. They can withstand various processing conditions, such as heat, acidity, and alkalinity. This stability makes the extract a very reliable ingredient in different applications. For example, in the food and beverage industry, products may go through various processing steps, including heating, and the steviol glycosides in the Stevia Extract will not break down easily, maintaining their sweetening power.

Concentrated Flavor

The extract obtained through CO₂ extraction has a concentrated flavor. This means that a small amount of the extract can provide a significant level of sweetness. This is beneficial in many ways. For manufacturers, it allows them to use less of the ingredient to achieve the desired sweetness in their products, which can potentially reduce costs. For consumers, it means that they can use a small quantity of the Stevia Extract to sweeten their drinks or foods without overpowering other flavors.
