During fermentation the pH decreased to around 4.6 for the salami samples.Forthemorrsamples,thepHincreasedsubstantiallyandaveraged at 5.5 at the end of fermentation period, independently of conditions used. In another study, where HHP was not used, the pH range for morr and salami was 4.39–5.19 and 4.41–5.08 respectively, and the pH evolution was mainly explained by the level of added glucose with lower average values in sausages with high batter glucose (Heir et al., 2010). A study (Omer et al., 2010) found that there was no difference between the means of the final pH of morr with 4.94 and that of salami with 4.77. But higher ultimate pH was also registered in
