Estudio de la Stevia (Stevia rebaudianaBertoni ResumenLa stevia, conocida también como "El edulcorante milagroso", es considerada el mejor sustituto del azúcar debido a que es hasta 300 veces más dulce y no contiene calorías. Este arbusto, cultivado en los bosques de Brasil y Paraguay, presenta en su composición un alto porcentaje de glucósidos de esteviol (esteviósido y rebaudiosida A), los cuales le confieren un sabor dulce intenso y propiedades terapéuticas contra la diabetes, la hipertensión y la obesidad; además ayuda al control del peso, la saciedad y el hambre. Por su contenido en compuestos fenólicos, la stevia actúa también como un excelente antioxidante y anticancerígeno; asimismo se ha demostrado que posee propiedades antibacterianas, anticonceptivas y diuréticas. Este trabajo de revisión tuvo como objetivo, recopilar información sobre los estudios realizados a la stevia como alternativa al azúcar y los beneficios de su consumo.Palabras clave: Stevia rebaudiana, edulcorante natural, glucósidos de esteviol, diabetes, antioxidante. AbstractStevia, also known as "The miracle sweetener", is considered the best sugar substitute because it is up to 300 times sweeter and contains no calories. This shrub, grown in the forests of Brazil and Paraguay, has in its composition a high percentage of steviol glycosides (stevioside and rebaudioside A), which give it an intensely sweet taste and therapeutic properties against diabetes, hypertension and obesity also helps control weight, satiety and hunger. For its content in phenolic compounds, Stevia also acts as an excellent antioxidant and anticarcinogenic; also has been shown to have antibacterial, contraceptive, and diuretic properties. This review paper aims to collect information on the studies undertaken to stevia as an alternative to sugar and the benefits it provides consumption.

BACKGROUND Andean purple maize (APM) is an ancient crop widely used as a natural coloring in traditional Peruvian cuisine. However, it has been little explored within the food industry. The present study assessed how APM impacts on techno‐functional properties and sensory acceptance of breakfast cereals. Extruded samples formulated with 100, 75, 50, and 25% APM, and complemented with yellow corn grits (YCG), were analyzed for their techno‐functional and sensory properties. RESULTS Increases in bulk density, as well as reduction in the expantion and porosity were observated for extrudates containing ≥ 50% APM, accompanied by an increase in purple color intensity. Increase in milk absorption index, reduction in milk solubility index and decrease in cereal hardness with increase in APM were also observed. Despite this, APM extented the cereal bowl‐life. High sensory scores of overall liking (6) and color (7) were obtained for extruded formulations containing ≥ 50% APM and low values for extrudates with 25% APM. Aroma, flavor, and texture scores did not present significant differences. CONCLUSION APM is an ingredient with the potential to be used to produce breakfast cereals since it improves their techno‐functional characteristics and sensory acceptance, at the same time, it leads to the production of healthy, nutritious, and sustainable food. © 2022 Society of Chemical Industry.
