ABSTRACT
Abstract This study aimed to develop and evaluate fermented milk by Lactobacillus reuteri LR92 with addition of juçara pulp (FMJ) and reuterin production in situ. The fermentation process was analyzed for 24 hours and the storage of FMJ for 30 days at 4 °C. During the fermentation, there was consumption of 25% (w / v) of lactose and increase of 0.01 to 0.85% (w / v) of lactic acid. The FMJ presented 0.43 ± 0.01 mM of reuterin, inhibiting Staphylococcus aureus strains under in vitro test. For the carbohydrates, the percentages (g.100g-1) found were 7.31 ± 1.07; 9.19 ± 0.82; 1.60 ± 0.50 and 0.08 ± 0.00 for sucrose, lactose, galactose and fructose respectively. The survival of L. reuteri, present in FMJ, was 2.47 log CFU / mL after 6 hours of gastrointestinal simulation. In sensory analysis FMJ received a grade 7 for global acceptance indicating good acceptance of the product.
