Influence of aqueous ozone, blanching and combined treatments on microbial load...
Alexandre, Elisabete M. C.; Santos-Pedro, Dora M.; Brandão, Teresa R. S.; Silva, Cristina L. M.The effectiveness of ozone in aqueous solution treatment on microbial inactivation was studied for three combinations microorganism/food: Listeria innocua/red bell peppers (artificially inoculated), total mesophiles/strawberries, and total coliforms/watercress, with two concentrations (0.3 and 2.0 ppm). Blanching treatments (50–60 C) were also individually applied and in combination with ozone, for studying po...
Study on thermosonication and ultraviolet radiation processes as an alternative...
Alexandre, Elisabete M. C.; Santos-Pedro, Dora M.; Brandão, Teresa R. S.; Silva, Cristina L. M.The impacts of ultraviolet-C radiation, blanching by heat, and combination of heat/ultrasounds (thermosonication) were studied for Listeria innocua (inoculated) in red bell peppers, total mesophiles in strawberries and total coliforms in watercress, in the temperature range 50–65 °C. Quality attributes such as colour and firmness were studied for all products, and total anthocyanins content was additionally det...
