Fruits and vegetables consumption has risen noticeably during recent decades, leading to a greater frequency of foodborne illnesses associated with fresh produce. Novel industrial applications and improvements in ozone technology together with new regulatory actions worldwide have emerged in recent years, making its use in the food industry easier. This technology has attracted considerable commercial interest, especially because ozone does not leave any residues on the treated produce and it is also accepted by many organic grower organizations. However, discrepancies regarding the efficacy of this technology are often found in the bibliography and further research is still needed. These differences could be attributed to a great variability in the conditions of the research work: method of ozone generation and application, O3 concentration and exposure time to the gas, as well as the way in which produce is packed. In this sense, standardization in the working conditions and in the units to measure ozone concentration will be useful to better understand the mode of action and the effects of ozone on food products. Consequently, it would be possible to improve its potential as a sanitizer in the food industry. 相似文献

The need for sustainable food production and the demand for fresh and minimally processed foods have prompted remarkable research in novel food processing technologies that ensure safe and shelf-stable food for a large population. Long-established techniques such as heating, drying, and freezing have been associated with nutrient loss and high energy consumption. This trend has drawn attention to the practice of employing ozone in several food applications owing to its significant disinfectant and antimicrobial efficiency. The aqueous form of ozone has been found to show greater efficacy than its gaseous form, with faster decomposition rates leaving no harmful residues. The current study presents an overview of the latest scientific literature on the properties, chemistry, and generation of aqueous ozone, emphasizing the factors affecting process efficiency. The review scrupulously focuses on food decontamination, starch modification, pesticide degradation, and seed germination effects of aqueous ozone, highlighting the optimum processing parameters and salient findings of some major studies. A brief insight into the limitations and future trends has also been presented. Aqueous ozone has been acclaimed to have the potential to cause significant changes in the food matrix that could result in constructive modifications with outcomes entirely dependent on the processing conditions. Indirect and direct reactions involving hydroxyl radical and molecular oxygen atoms, respectively, form the basis of the ozone reaction in aqueous media, providing a distinctive kind of advanced oxidation process that offers certain crucial benefits. With a shorter half-life in water as compared to air, the rapid decomposition of aqueous ozone to oxygen, leaving no harmful residues, adds to its advantages. 相似文献
