The initial mean pH value of the meat batter was 5.85. After 6 days of ripening at 15 C, a significant reduction of pH (p < 0.05) was observed in the batches inoculated with the strains L. casei/paracasei CTC1677 and CTC1678 and L. rhamnosus CTC1679, achieving pH values of 5.53, 5.28 and 5.31, respectively.
