Lin (2000) and Rosi (1978), and in line with the level reported by
Kilic et al. (1999). Prickly pear FJ was characterized by the highest
microbial loads. Although after pasteurization Enterobacteriaceae
and pseudomonads were undetectable, they developed after
fermentation. This result might be imputable to the almost neutral
pH (6.26) of prickly pear juice that is not inhibitory for these undesired
microorganisms.
