- Abstract
Stevia leaves (Stevia rebaudiana Bertoni) are considered natural, harmless, non-caloric sweeteners. The stems of the stevia plant hadn't been as researched and are considered waste or agro-industrial byproducts, yet a good source of potentially techno-functional fiber, which could be considered as a food ingredient. The aim of this work was to evaluate the chemical and techno-functional properties of stevia stems as a potential ingredient for functional foods. The stems were obtained from stevia plantations in the state of Yucatan - Mexico, and their proximal chemical composition and techno-functional profile were determined considering water and oil retention, water absorption and adsorption, and the organic molecules absorption capacity. The analytical determinations were performed in triplicate and a one-way analysis of variance was used for the statistical analysis of the data obtained. They presented a high content of carbohydrates (54.84 %), crude fiber (32.33 %), ash (6.99 %), and protein (4.46 %). The stems retained five times their weight in water and oil, with 5.57 and 5.00 g/g, respectively. Their organic molecules absorption capacity was 2.09 g/g, with 4.49 g/g for water absorption and 0.29 g/g for water adsorption. As an agricultural byproduct of stevia leaves harvesting, the stems are a functional alternative to use in food preparations with potential physiological effects.
