Full textThe fresh cut industry uses chlorine-based chemicals and large quantities of water for its washing and decontamination operations. These practices are increasingly coming up against consumers' health expectations and environmental constraints. Alternative solutions must befound ; It is with this in mind that this thesis work focuses on high-frequency acoustic waves. The research project revolves around two major axes, which are, on the one hand, the disinfection of wash water via a sonoreactor for recycling and on the other hand, the decontamination of plants through cleaning by high-frequency ultrasonic waves called megasounds. The performance levels, the mechanisms involved and the compatibility of this technology on 4th range lettuce and its microflora were evaluated. The results obtained show, for both lines of research, that this technology is functional. The sonoreactor using low-frequency ultrasounds disinfects lettuce washing water with values of the order of 90%. Its antibacterial efficacy is also observable on pathogenic strains : Escherichia coli, Salmonella enterica and Listeria monocytogenes. Scanning electron microscopy confirms the inactivation of microorganisms, mainly through the collapse of transient cavitation bubbles. Exposure of Batavia lettuce to megasounds gives microbiological reduction levels equivalent to those of chlorine 80 ppm and this, just after treatment and during storage in trays at 4 ° C. The visual and organoleptic quality as well as the shelf life of the products are not altered. Physiological and metabolic parameters such as membrane permeability, mineral concentration, vitamin C content and respiration show no significant changes. The efficiency of stall microorganisms by megasounds on the surface of plants seems to vary according to the bacterial groups composing the total flora. Additional metabarcoding analyses will make it possible to specify the results obtained on selective media. In order to initiate new perspectives of applications to the project, a study on the imbibition and germination of bean seeds by megasonic treatments was carried out. The results show an involvement of water having undergone megasounds in the earlier germination of seeds.Infradoses of H2O2 could act in the process. The information gathered during this work made it possible to optimize the design and manufacture, within the company Electronie, of two new prototypes (a megasounds tank and a sonoreactor) from previous patents. A system improving the disinfection performance of the sonoreactor was also the subject of a declaration of invention. The project continues its development and enters a more industrial phase with the close collaboration of professionals from the agri-food sector

Full textThe gliding electrical discharge "Glidarc" in the humid air is a source of non-thermal plasma at atmospheric pressure efficient for pollution abatement. We present in this thesis the benefit use of reactive properties in temporal post-discharge (i. E. After switch off the discharge) of glidarc. In the first step, we considered the degradation of acidic methyl orange, an azoic dye. After target exposure for short periods to the discharge plasma, a strong temporal post-discharge degradation of the dye giving N,N-dimethyl-4-Nitroaniline, as the major yellow intermediate product with a relevant overall first-order kinetics, was observed. On the other hand, post-discharge has also been used to inactivate micro-organisms. Four micro-organisms in planktonic and adherent forms were considered: Staphylococcus epidermidis and Leuconostoc mesenteroïdes as Gram-positive bacteria, Hafnia alvei as a gram-negative bacterium and Saccharomyces cerevisiae as a yeast model. The post-discharge was used in two ways: the microbial cells were previously exposed to discharge for short periods or they were inactivated by a solution of "plasma activated water”. In all cases, significant reductions of the microbial populations were achieved with 1st order kinetic. Such results combined with the identification of the destruction by HNO2 and H2O2 suggest that nitrous and peroxonitrous acids are the main oxidizing species involved in the temporal post-discharge phenomenon. As the operation takes place under acidic medium, the role of nitrosonium NO+ was also highlighted
