Resumo
Nos últimos anos tem havido muito interesse por produtos alimentícios de baixas calorias e probióticos. A incorporação de Lactobacillus acidophilus e Bifidobacterium em bebidas fermentadas pode resultar em um produto lácteo com extraordinário valor terapêutico e eficaz redução calórica. O objetivo deste trabalho foi estudar o efeito do teor de soro, açúcar e de frutooligossacarídeos sobre a população de bactérias lácticas de doze formulações de bebidas fermentadas. Foram determinadas as populações de Streptococcus thermophilus, Lactobacillus delbrueckii subsp. bulgaricus, Bifidobacterium e Lactobacillus acidophilus. As maiores populações de microrganismos probióticos foram observadas nas bebidas com mais baixa acidez e elevado teor de sólidos, além de haver predominância do Streptococcus thermophilus sobre os demais microrganismos. As amostras atenderam a legislação brasileira em vigor, independente das formulações, pela presença de no mínimo 10(6) UFC/mL de bactérias lácticas. As bebidas lácteas formuladas podem ser consideradas probióticas pelas contagens elevadas de Bifidobacterium spp. e Lactobacillus acidophilus
The demand for low calories and probiotics foods has increased during the last years. The incorporation of Lactobacillus acidophilus and Bifidobacterium in fermented beverages can result in dairy products with excellent therapeutic value and efficient calories reduction. The aim of this research was study the effects of whey, sugar and fructooligosaccharides levels on the lactic acid bacteria population of twelve formulations of fermented beverages. The populations of Streptococcus thermophilus, Lactobacillus delbrueckii subsp. bulgaricus, Bifidobacterium spp. and Lactobacillus acidophilus were carried out. The highest probiotic microorganisms' populations were observed in beverages with lower acidity and higher solids level, besides there was a predominance of Streptococcus thermophilus over the other microorganisms. All samples attended the Brazilian legislation in force, instead of the different formulation, because they presented at least 10(6) colony-forming units per mL of lactic acid bacteria. The produced dairy beverages could be considered probiotics due to the high counts of the Bifidobacterium spp. and Lactobacillus acidophilus
