Sucrose-free milk chocolate manufacture using bulking agents and a non-caloric sweetener Ciênc. Tecnol. Aliment.
AGUILAR-VILLA,Carolina; ACOSTA-OTÁLVARO,Elly Vannesa; RODRÍGUEZ-SANDOVAL,Eduardo; MAZO-RIVAS,Juan Camilo.
Abstract Sucrose is important in the production of chocolates because it contributes to its texture and sensory acceptance. The aim was to evaluate the effect of adding bulking agents and a non-caloric sweetener in the preparation of a sucrose-free milk chocolate. One control sample (with sucrose) and 11 treatments were taken varying the ratio between bulking agents (maltitol, polydextrose, inulin) and non-caloric sweetener (stevia), preserving the sweetness of control. Sensory acceptance of each treatment was evaluated by preference tests and taste profile. Principal component analysis (PCA) showed that formulations with maltitol and stevia (F7); and maltitol, polydextrose, inulin and stevia (F10) were the most similar to control in their sensory and...

Cultivo in vitro de Stevia rebaudiana Bertoni. Colegio de Postgraduados
Vázquez Baxcajay, Liberia.
Stevia es un género de plantas fanerógamas perteneciente a la familia de las asteráceas, tiene 407 especies; una de sus especies es Stevia rebaudiana Bertoni, nombrada así por Moisés de Santiago Bertoni. Para el establecimiento in vitro de Stevia rebaudiana se aplicaron cinco tratamientos de desinfestación y se obtuvo al usar Cloro® (1.8 % cloro activo), Ridomil y Fungimycin previo a la siembra in vitro y al agregar al medio Cefotaxima (500 mgL-1) se obtuvo un porcentaje de contaminación de 50 % permitiendo una supervivencia de 47 %. En la inducción de callo se mostro que al combinar 1.5 mgL-1 2,4-D/AIA la capacidad de formación de callo del explante de hoja es de 25 %. El tratamiento de cinetina (1.3 gL-1) en el proceso micropropagación de Stevia mostro...

Requerimiento de nitrógeno en la producción de Stevia rebaudiana Bertoni en hidroponía e invernadero. Colegio de Postgraduados
Salgado Cordero, Luz Eréndira.
La Stevia rebaudiana, también llamada hierba dulce o Ka’a-He’e, es una herbácea semiperenne de la flora paraguaya perteneciente a la familia Asteraceae. La estevia es empleada por la industria alimentaria y farmacéutica debido a compuestos glucósidos que se obtienen a partir de la hoja, los cuales tienen un poder edulcorante hasta 250 a 300 veces mayor a la de la sacarosa. La presente investigación se realizó con el objetivo de evaluar el efecto de diferentes niveles de nitrato sobre la producción de biomasa, la concentración foliar y requerimiento de nitrógeno (N) en plantas de estevia en hidroponía. El experimento se realizó en un invernadero del Colegio de Postgraduados, en Texcoco, México, se utilizó riego por goteo y un sustrato con una mezcla 70:30...

Pollen viability and meiotic irregularities in a collection of Stevia rebaudiana (Bertoni) Bertoni cultivated in Tucumán, Argentina JBAG
Budeguer,C.J; Camadro,E.L; Erazzú,L.E.
Stevia rebaudiana (Bertoni) Bertoni (2n=2x=22) (Asteraceae family) is a species of economic value due to the presence of steviol glycosides in leaves -mainly stevioside and rebaudioside A- which are non-caloric sugars. In 2013, a collection of plants (genotypes) from four contrasting environments was established in Tucuman, Argentina, for evaluation under local conditions and, eventually, breeding purposes. As a first step, pollen viability and meiosis was studied in a sample of 56 plants. The percentage of pollen viability varied from medium (69.4%) to high (99.6%) in 52 of them, but from low (36.5%) to relatively low (51.5%) in the remaining four. The latter four plants also presented pollen grains of heterogeneous size, which were classified as n...
