Microbial quality of bread crumbs
Contamination degree of bread crumbs by aerobic mesophilic bacteria, aerobic sporogenic bacteria, bacteria of Enterobacteriaceae family and moulds was investigated. Total of 34 samples of bread crumbs was microbiologically analyzed. Water activity was also measured in bread crumbs samples. Bread crumbs were averagely contaminated with 3×103 aerobic mesophilic bacteria, 3, 3×103 aerobic sporogenic bacteria and 1, 62×104 moulds in 1 g of the sample. Bacteria of Enterobacteriaceae family were not detected in any of analyzed samples. Water activity was averagely 0, 305. Following mould genera predominated in bread crumbs: Penicillium (61, 29 %) and Aspergillus (18, 06 %). Many species of these genera are known mycotoxin producers. Following species of mold genera: Geomyces (6, 45 %), Absidia (4, 52 %), Fusarium (3, 87 %), Cladosporium (2, 58 %) i Alternaria (0, 65 %) were detected in analyzed samples. Aspergillus ustus was dominant species of Aspergillus genera in analyzed samples with 92, 86 %, while A. flavus was detected in only one analyzed sample (3, 57 %). Bread crumbs are usually produced from bread returns. To avoid potential risk of mold and mycotoxin contamination, as well as contamination by aerobic sporogenic bacteria bread used for crumbing must be of good microbiological quality.
