at the end of ripening could be an option to inactivate the enzymes
involved. Further evaluation of the feasibility and acceptability of pas-
teurized sufu would be required.
6.2.4 Microbial and Biochemistry Changes during Production
6.2.4.1 Microbial Changes Although a pure culture is used in pehtze
fermentation, the process of sufu manufacture itself is carried out
under nonsterile conditions, so, in addition to the mold starter, other
micro organ isms may be expected to be present in sufu. e quan-
titative evolution of microflora of sufu was studied throughout the
production, with special attention to the effect of different salt con-
tents during the ripening (Han, 2003). Total counts of mesophilic
aerobic bacteria ...
