Combining High-Pressure Processing and Supercritical Carbon Dioxide for Inactivation of Listeria innocua
نویسندگان
چکیده
The effect of high-pressure treatment with supercritical CO2 on the inactivation Listeria innocua in a fish soup was investigated. inoculated L. innocua, packaged modified atmosphere 50:50 or 95:5 CO2:N2, processed (300, 350, 400 and 600 MPa, 2 min) under subcritical (T < 304 K) conditions > stored at 4 °C for up to 53 days. Treatment MPa had significant (p 0.05) both conditions. In contrast, pressurization 350 were needed significantly inactive innocua. Increased levels headspace reduced bacterial load during processing, 0.01) interaction pressure. storage time gave increased MPa. addition, high decreased 0.001) growth. However, seemed set permanent lag phase, slow steadily decreasing numbers bacteria storage. All design variables resulted combined inhibited recovery large degree.

Measurement and Modeling of Acridine Solubility in Supercritical Carbon Dioxide
Supercritical carbon dioxide has gained increasing attention in food and pharmaceutical processing owing to the fact that it is environmentally inexpensive, not flammable, essentially non-toxic, and it has a convenient critical point. Also, it has been attracting much attention in many fields, such as extraction of sensitive materials and pharmaceutical processing and polymerization processes. ...
متن کاملSynthesis and Processing of Porous Polymers Using Supercritical Carbon Dioxide
The production of porous polymers is often solvent intensive. As environmental regulations become more stringent, there is a need to consider cleaner routes to these materials. Carbon dioxide has emerged as a clean and versatile solvent for the synthesis and processing of a range of polymers(1). CO2 is inexpensive, non-toxic, non-flammable, and easily separated from products. This review focuse...
متن کاملInactivation of Escherichia coli and Listeria innocua in milk by combined treatment with high hydrostatic pressure and the lactoperoxidase system.
We have studied inactivation of four strains each of Escherichia coli and Listeria innocua in milk by the combined use of high hydrostatic pressure and the lactoperoxidase-thiocyanate-hydrogen peroxide system as a potential mild food preservation method. The lactoperoxidase system alone exerted a bacteriostatic effect on both species for at least 24 h at room temperature, but none of the strain...
