ABSTRACT

RESUMEN El objetivo de este trabajo fue evaluar el efecto de las diferentes concentraciones de polidextrosa en la prevención de la obesidad y sus comorbilidades, en ratas alimentados con dieta hipercalórica. Se utilizaron ratas machos Wistar, repartidos en 4 grupos: Grupo control (HC) y 3 grupos que recibieron dieta hipercalórica con suplementación del 2%, 4% y 6% de polidextrosa (HC2%P, HC4%P y HC6%P respectivamente). La dieta hipercalórica utilizada fue la del tipo de cafetería para inducir la obesidad. Se midió peso corporal e ingesta de la dieta, se realizaron pruebas de tolerancia a la glucosa y a la insulina. Los animales fueron sometidos a eutanasia para toma de muestra de sangre medidas antropométricas y pesaje de órganos y tejidos. La polidextrosa disminuyó significantemente el peso, la grasa corporal, la glicemia, los triglicéridos, la intolerancia a la glucosa y la resistencia a la insulina, y aumentó los niveles del colesterol HDL. Se concluye que el consumo de poli- dextrosa redujo las complicaciones derivadas de la obesidad en ratas alimentados con dieta hipercalórica, siendo éste un potencial tratamiento para el control de la obesidad, la diabetes tipo II y las enfermedades cardiovasculares.


ABSTRACT The aim of this study was to evaluate the effect of different polydextrose concentrations for the prevention of obesity and its comorbidities in rats fed a high calorie diet. Thirty male Wistar rats were used. Rats were divided into 4 groups: Control group (HC) and 3 groups which received a hypercaloric diet with 2%, 4% and 6% polydextrose supplementation (HC2%P, HC4%P and HC6%P, respectively). The hypercaloric diet used was of the cafeteria type to induce obesity. Body weight and feed intake were verified weekly. Glucose and insulin tolerance tests were performed five days before finalizing the experiment. At the end of the experiment, animals were euthanized for blood collection, anthropometric measurements and tissue weighing. Polydextrose significantly decreased weight, body fat, blood glucose, triglycerides, glucose intolerance and insulin resistance and increased HDL cholesterol levels. The use of polydextrose reduced the complications of obesity in mice fed a hypercaloric diet. In conclusion, polydextrose may be a promising treatment for controlling obesity, diabetes type II and cardiovascular diseases.

ABSTRACT

Introdução: a farinha de banana verde (FBV) é um alimento que vem se destacando pelas suas propriedades funcionais e, ainda, mostra-se um ingrediente potencial e viável para o enriquecimento de alimentos. Objetivo: verificar a aceitabilidade sensorial de pães adicionados de farinha de banana verde (FBV). Também, determinar a composição físico-química da formulação padrão e daquela contendo o maior teor de FBV e com aceitação sensorial semelhante a padrão. Métodos: foram elaboradas cinco formulações de pães sendo: padrão (F1) e as demais com adição de 7,5% (F2), 15% (F3), 22,5% (F4) e 30% (F5) de FBV. Participaram da análise sensorial 120 mulheres, não treinadas, com idade entre 18 a 70 anos. Resultados e Discussão: a formulação F2 foi aquela com o maior teor de FBV e com aceitação semelhante a padrão em todos os atributos avaliados de aparência, aroma, sabor, textura, maciez, cor e aceitação global e intenção de compra. Não houve diferença significativa entre as amostras F1 e F2 nos teores de umidade, proteína e lipídeos. Porém, ocorreu uma redução no conteúdo de carboidratos e calorias em F2 e um aumento de cinzas e fibras. Conclusão: um nível de adição de até 7,5% de FBV em pão foi bem aceito pelos provadores, obtendo-se aceitação sensorial semelhante ao produto padrão e com boas expectativas de comercialização.


Introduction: green banana flour is becoming increasing known for its functional properties and arises as a potential item for food enrichment. Objective: to verify the sensory acceptability of bread added green banana flour (GBF). Also, to determine the physico-chemical composition of the standard formulation and that containing the largest GBF content and sensory acceptance similar to standard. Methods: five formulations of breads were prepared as follows: standard (F1) and the other with addition of 7.5% (F2), 15% (F3), 22.5% (F4) and 30% (F5) of GBF. Participated in the sensory analysis 120 women, untrained, aged 18 to 70 years. Results and Discussion: the F2 formulation was the one with the most GBF content and similar acceptance standard in all attributes: appearance, aroma, taste, texture, softness, color and overall acceptance and purchase intent. There was no significant difference between the samples F1 and F2 on moisture, protein and lipids. However, there was a reduction in calories and carbohydrate content in F2 and an increase of ash and fiber. Conclusion: a level of addition of up to 7.5% GBF in bread was well accepted by the judges, resulting in sensory acceptance similar to the standard product with good marketing expectations.
