Effect of the use of gums on the viscosity and sensory characteristics of a shake based on green banana flour

<p></p><p>Abstract This 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.</p><p></p>
