Leites fermentados foram elaborados a partir de bactérias ácido-lácticas com propriedades funcionais, isoladas de queijo de coalho com e sem a adição de concentrado proteico de soro (CPS). Características físico-químicas, microbiológicas e sensoriais dos produtos elaborados foram analisadas durante 40 dias de estocagem sob refrigeração a 8-10ºC. Todos os leites fermentados elaborados, independentemente da adição de CPS e da cultura utilizada, apresentaram contagens adequadas de bactérias (>10(8)UFC/mL) durante todo o período de avaliação, o que garantiria seu possível potencial funcional. Leites fermentados por Lactobacillus acidophilus apresentaram melhor aceitação (PFermented milks were produced using whey protein concentrate (WPC) and potentially functional lactic acid bacteria, which were isolated from coalho cheese produced in. Physical-chemical, microbiological, and sensorial characteristics of the fermented milks were analyzed during 40 days under refrigeration at 8-10ºC. All products, irrespectively of WPC adding or culture used, showed appropriated bacterial counts (>10(8)CFU/mL) throughout the evaluation time, which would guarantee their functional potential. Lactobacillus acidophilus fermented milks presented better sensorial approval (P<0.05) when evaluated at 10-day storage; while Weissella confusa fermented milks presented lower acceptance (P<0.05) at 40-day storage. The association of Lactobacillus acidophilus and Weissella confusa or Lactobacillus acidophilus isolatedly, irrespectively of WPC adding, should be recommended for the industrial elaboration of novel functional fermented milks using Brazilian lactic cultures as starters.
