Inactivation of Staphylococcus aureus and native microflora in human milk by high pressure processing

摘要: The storage of unpreserved food, including breast milk, is associated with the growth microorganisms, pathogenic bacteria. It therefore necessary to use suitable processes eliminate microorganisms and reduce total microbial count in order ensure product safety for consumers. In present study, samples milk obtained from volunteers donating human bank were artificially contaminated Staphylococcus aureus ATCC 6538. This bacteria was model microorganism choice, being relatively resistant high pressure as well posing most serious risk infant health. results show that processing can S. by about 5 log units at 4°C 8 log 50°C, totally Enterobacteriaceae after 5 min treatment, result a reduction 10 min treatment 500 MPa 20°C 50°C. suggests possibility this technology applied ensure...
