Abstract
This work aimed to evaluate the physicochemical, microbiological parameters and acceptability of functional yogurt, with and without fructooligosaccharide supplementation, flavor yellow mombin . Four yogurt formulations were elaborated: two with whole milk with and without fructooligosaccharide supplementation, and two with skimmed milk with and without fructooligosaccharide supplementation. It was evaluated the formulations’ pH, titratable acidity, soluble solids, microbiological quality standards, total lactic acid bacteria count, and sensory analysis. Questions were asked about frequency of consumption, knowledge of the benefits related to the consumption of fermented dairy products, purchase intention and acceptability index. Regarding pH, the formulation made with whole milk and fructooligosaccharides showed significant difference (p < 0.05) compared to the other formulations. It was observed no significant differences (p > 0.05) regarding titratable acidity and soluble solids. The total lactic bacteria count has shown high values that meet the parameters of the legislation. The described formulations of satisfactory hygienic and sanitary quality were well accepted by consumers for all sensory detection tests, being viable in sensory, physicochemical and microbiological terms, with potential use by the population for its symbiotic characteristics and health benefits.
