Efficacy of supercritical carbon dioxide for nonthermal inactivation of Escherichia coli K12 in apple cider.

This study evaluated the efficacy of a supercritical carbon dioxide (SCCO(2)) system with a gas-liquid porous metal contactor for eliminating Escherichia coli K12 in apple cider. Pasteurized, preservative-free apple cider was inoculated with E. coli K12 and processed using the SCCO(2) system at CO(2) concentrations of 0-10% (wt.%, g CO(2)/100g product), outlet temperatures of 34, 38, and 42 deg...

Reactions in supercritical carbon dioxide

Use of conventional organic solvents often leads to the formation of hazardous waste, the disposal of which is a matter of environmental concern. Carbon dioxide is considered to be a green reaction medium and a good replacement for conventional organic solvents as it is benign and leads to elimination/reduction of hazardous wastes. Use of CO2 at near/above critical conditions has several additi...

The Effect of Gamma (γ) Irradiation to inactivate Escherichia coli in Contaminated water

Several common approaches are used for disinfection of water in this section, but using the approaches (e.g. chlorination) are accompanied with hazardous by-products and also lead to notable changes in odor and flavor of water. Gamma irradiation as an emerging method has been encouraged currently by FAO/WHO for water, wastewater and food treatment. Coliform bacteria belong to common contaminant...
