What is Stevia
Stevia is a plant native to South America. It is part of the sunflower family, and its leaves are naturally sweet. In fact, the indigenous people of Paraguay used to chew them for their sweet taste, and use them to naturally sweeten beverages.
The leaves of the stevia plant contain sweet tasting components, scientifically called steviol glycosides. To date, about 50 steviol glycosides have been identified, and a typical stevia leaf has nine which are most abundant. Each steviol glycoside has its own unique taste profile, and sweetness intensity can be anywhere from 200 to 350 times sweeter than sugar – but without the calories that sugar brings.
Stevia has been used for hundreds of years and today its use in foods and beverages is backed by science. There are now over 200 scientific research studies that support the science and safety of high-purity stevia extracts used in foods and beverages.
Stevia Leaf Extracts
The form of stevia found in today’s foods and beverages around the world is generally high-purity stevia leaf extract, which is a purified form of stevia extract that has been evaluated and approved by major regulatory agencies around the world. Purified stevia leaf extracts can contain one steviol glycoside or several different glycosides, and can be up to 350 times sweeter than sucrose. High-purity stevia leaf extract is a versatile sweetening ingredient for foods and beverages, and offers consumers and food and beverage manufacturers a new option for natural-origin sweetness without the calories.
Crude stevia extracts and or whole stevia plant leaves are sold as dietary supplements in some countries, but it is important to note that only high-purity stevia leaf extract has been evaluated and approved for use as an ingredient in foods and beverages by the world’s major regulatory agencies. Throughout this website, we will refer to high-purity stevia leaf extract simply as stevia.
More and more food and beverage companies are using stevia to help create great-tasting food and beverage products with less sugar and fewer total calories. As a result, you may see a reduction in sugar and total calories per serving. On the ingredient label, you may see stevia listed in different ways: stevia, stevia extract, rebaudioside A, Reb A, steviol glycosides and other variations depending on the country and the manufacturer. Stevia can be found in more than 14,000 foods and beverages around the globe today, including juices, waters, soft drinks, flavored milks, yogurts, baked goods, cereals, salad dressings, sauces, confections, tabletop sweeteners and more. The powerful combination of a zero-calorie sweetener with a plant-based origin, makes stevia distinct in the food and beverage world.
How is stevia made?
To release the sweetness, the steviol glycosides are extracted and purified from the stevia leaf, like other ingredients you may commonly use, such as sucrose (sugar) from sugarcane or natural vanilla extract from the vanilla bean. At the end of the extraction and purification process, the sweet components are the exact same compounds as the ones originally found in the leaf. This process produces high-purity stevia leaf extract, which meets the specifications approved by major regulatory bodies for use in foods and beverages around the world.
