Avaliação das propriedades funcionais de Muesli sobre os sinais subjetivos da fome, saciedade e humor

Abstract

Foods that have bioactive compounds in specific amounts are considered foods with functional properties and have metabolic and/or physiological effects, promoting health benefits when combined with healthy eating. Muesli is an oat-based breakfast cereal that is a source of protein and dietary fiber. This study aimed to verify whether the functional claim present in a muesli formulation influenced the hunger, satiety and mood of healthy adults. The products were formulated with food ingredients containing bioactive compounds with functional property claim. To assess the effect of muesli consumption on mood and satiety, nine subjects were randomly recruited and exposed to three samples of the products, two of which were the same oat formulation, but only one showed the claim of functional property; and another with the replacement of oats by rice flakes, also without claim. Questionnaires for sensory analysis, mood and perceived satiety were applied. The results were subjected to appropriate statistical treatment, adopting p<0.05. The oat muesli when compared to the rice flakes had no statistically significant difference in the parameters of hunger, satiety and mean mood. Sensory attributes such as palatability and appearance may have influenced the results. Thus, we concluded that the functional claim, as well as the amount of β-glucan present in the sample was not enough to influence the hunger, satiety and subjective mood of consumers.
