Desenvolvimento de iogurte caprino com potencial probiótico: características tecnológicas e avaliação do efeito protetor da matriz alimentar

The production of goat yogurt with the addition of probiotic cultures and honey bee Melipona scutellaris to flavor and add functional value to the product can potentiate the beneficial effects to health and, therefore, the demand of this product by the consumer. The present study was carried out with the objective of developing goat yoghurt with probiotic potential of honey bee Melipona scutellaris and characterizing the technological, physical, chemical, microbiological and sensorial aspects, as well as evaluating the protective effect of the food matrix on the strains Added. The effect of adding probiotic lactic and honey cultures on the quality characteristics of fermented yogurts was evaluated at times 1, 7, 14, 21 and 28 days of refrigerated storage, considering the following treatments: IC (conventional yogurt - control), Containing the starter culture composed of Streptococcus thermophilus and Lactobacillus delbrüeckii subsp. Bulgaricus; IP, containing the probiotic microorganism Lactobacillus acidophilus, in co-culture with the starter; IPM, composed of the probiotic Lactobacillus acidophilus, in addition to starter culture and added of bee honey; And IM, containing the culture starter and added of honey of bee. All the yoghurt formulations tested showed good results on the technological characteristics, showing good stability. The samples were sensorially well accepted, with notes whose hedonic terms ranged from "I liked slightly" to "liked". In general, it was observed that the addition of the probiotic strain in the preparation of the yogurt did not influence the physical and physico-chemical characteristics of the same (p> 0.05). In the viscosity results, it was observed that honey-containing formulations (IPM and IM) showed an increase in viscosity during storage (p 0,05). Nos resultados da viscosidade, observou-se que as formulações que continham mel (IPM e IM) apresentaram um aumento da viscosidade durante o armazenamento (p
