Efeito da utilização de gomas na viscosidade e nas características sensoriais deshake à base de farinha de banana verde Effect of the use of gums on the viscosity and sensory characteristics of a shake based on green banana flour ResumoEste trabalho teve como objetivo testar diferentes proporções de gomas na elaboração de um shake desenvolvido com farinha de banana verde, além de avaliar as suas propriedades organolépticas. Analisaram-se seis formulações com os seguintes ingredientes: farinha de banana verde (FBV), leite em pó integral, sucralose, cacau e diferentes proporções de goma xantana (GX) e goma guar (GG), nas proporções (GX:GG): F1 (1:0); F2 (0:1); F3 (1:1); F4 (1:3); F5 (3:1); F6 sem estabilizante. As formulações de shake foram submetidas ao teste de viscosidade, realizado a cada três dias, durante um período de 15 dias. Foi realizada análise sensorial com voluntários, em cabines individuais. A aceitabilidade dos atributos aparência, aroma, sabor, textura e impressão global foi avaliada utilizando-se a escala hedônica de 9 pontos. Foram realizadas análises estatísticas utilizando-se o Teste de Variância (ANOVA) e o Teste de Tukey a 5% de probabilidade. O estudo foi importante para demonstrar que a viscosidade dos produtos influencia nas características sensoriais e, dessa forma, interfere na escolha dos consumidores.

AbstractThis study aimed to test different proportions of gums and evaluate the organoleptic properties of a shake developed with green banana flour. Six formulations were analysed with the following ingredients: green banana flour (FBV), whole milk powder, sucralose, cocoa and different ratios of xanthan gum (GX) and guar gum (GG), in the proportions (GX:GG) of: F1 (1:0); F2 (0:1); F3 (1:1); F4 (1:3); F5 (3:1); F6 with no stabilizer. The viscosity of the samples was determined every three days for a period of 15 days. A sensory analysis was carried out with volunteers in individual booths. The acceptability of the attributes of appearance, aroma, flavour, texture and overall impression was evaluated using a 9-point hedonic scale. Statistical analyses were carried out using the variance test (ANOVA) and Tukey's test at 5% probability. The study was important to demonstrate that the product viscosity influenced the sensory characteristics and hence interfered in the consumer choices. Keywords

Objective To assess the effect of a cocoa and unripe banana flour beverage (UBF) on fecal short‐chain fatty acids (SCFA), gastrointestinal symptoms, fecal characteristics and inflammation, in overweight women with abdominal adiposity. METHODS This prospective, double‐blinded, randomized clinical trial involved 60 female volunteers aged between 20 and 50 years. One group received a cocoa beverage (n = 30) and one group received a cocoa and UBF beverage (n = 30), for 6 weeks. Intestinal microbiota was indirectly assessed by consistency, shape, and color of feces, determination of fecal SCFA, and gastrointestinal symptoms. RESULTS Both beverages increased the production of propionic acid (p < .05) and decreased gastrointestinal symptoms (p < .05). The cocoa beverage decreased indigestion (p < .05) and the pro‐inflammatory cytokine, IL‐17. CONCLUSION Cocoa and cocoa with UBF beverages decreased the symptoms of dyspepsia, improved gastrointestinal symptoms, and increased production of propionic acid, favoring healthy intestinal microbiota. Only the cocoa beverage showed an anti‐inflammatory effect. Practical applications Unripe banana flour and cocoa have been widely used to decrease cardiovascular risk, by improving inflammatory parameters and gastrointestinal symptoms. However, the interaction between these two food ingredients and the implication of their interaction on human health remains unknown. Important health benefits may be achieved by assessing the synergism or antagonism of functional foods, particularly when they coexist in the same product. This study aims to attract the interest of the scientific community to conduct more studies on functional bioavailability. Both unripe banana flour and cocoa can have therapeutic potential but it may not be a good idea to associate them. This article provides relevant information to the scientific and broader community regarding the preparation of these foods, to maximize their health benefits on a daily basis, and, additionally, offers the food industry valuable knowledge that can be used to develop healthier food products.

Abstract. Objectives: The objective of this study was to evaluate the effect of a functional cocoa and unripe banana flour (UBF) beverage intake on the anthropometric and biochemical markers of overweight women. Methods: This prospective, double-blinded, randomized clinical trial involved 60 female volunteers aged between 20 and 50 years. One group received a cocoa beverage (n = 30) and one group received a cocoa and UBF beverage (n = 30), for 6 weeks. The cocoa beverage showed 3.07 total g dietary fiber/serving and 29.55 mg gallic acid equivalentes/portion (GAE/portion). Cocoa and UBF beverage contained 8.48% resistant starch by weight, 4.37 g dietary fiber/full portion and 69.24 mg GAE/portion. Weight, waist circumference, hip circumference, glucose, triglycerides, total cholesterol and fractions were evaluated. Results: The UBF and cocoa beverage reduced waist circumference (−2.03 cm, P < 0.001) and the cocoa beverage reduced total cholesterol (−19.3 mg/dL, P < 0.001) and the LDL/HDL ratio (−0.32, P < 0.001); in addition, both beverages promoted the reduction of body fat percentage (−1.98%, P = 0.001 and −1.15%, P < 0.001 Cocoa/UPF group and Cocoa group respectively). Conclusion: The additional dietary fiber did not further improve health status.
