“…Ozone is a potent oxidant and disinfecting agent that does not require thermal energy, so this technology should be considered suitable for heat-sensitive foods [160]. The bactericidal effect of ozone has been proved on a wide variety of organisms, including Gram-positive and Gram-negative bacteria, vegetative cells, and spores.…”

“…[133] The application of ozone is a bio-friendly technique and commercially feasible technology, making it a promising agent in the food industry. Moreover, there is no need for transportation, and all the treatments with ozone have lower running costs except for the first high cost for installation [160][161][162]. In addition, there is no need for management facilities of possible waste as there are none, nor are cleaning facilities of the required equipment necessary.…”

Nowadays, food treatment technologies are constantly evolving due to an increasing demand for healthier and tastier food with longer shelf lives. In this review, our aim is to highlight the advantages and disadvantages of some of the most exploited industrial techniques for food processing and microorganism deactivation, dividing them into those that exploit high temperatures (pasteurization, sterilization, aseptic packaging) and those that operate thanks to their inherent chemical–physical principles (ultrasound, ultraviolet radiation, ozonation, high hydrostatic pressure). The traditional thermal methods can reduce the number of pathogenic microorganisms to safe levels, but non-thermal technologies can also reduce or remove the adverse effects that occur using high temperatures. In the case of ultrasound, which inactivates pathogens, recent advances in food treatment are reported. Throughout the text, novel discoveries of the last decade are presented, and non-thermal methods have been demonstrated to be more attractive for processing a huge variety of foods. Preserving the quality and nutritional values of the product itself and at the same time reducing bacteria and extending shelf life are the primary targets of conscious producers, and with non-thermal technologies, they are increasingly possible.

“…Ozone has an oxidative potential of 2.07 V, which is nearly double the oxidizing potential of chlorine (1.36) and greater than the efficacy of peroxyacetic acid (1.81) [ 34 ]. The exclusion of heat generation during ozone treatment makes it adaptable for heat-sensitive foods [ 35 ]. The threshold limit of ozone exposure has usually been calculated as 8 h/day at 0.1 ppm (0.2 mg/m 3 ).…”

Meat may contain natural, spoilage, and pathogenic microorganisms based on the origin and characteristics of its dietary matrix. Several decontamination substances are used during or after meat processing, which include chlorine, organic acids, inorganic phosphates, benzoates, propionates, bacteriocins, or oxidizers. Unfortunately, traditional decontamination methods are often problematic because of their adverse impact on the quality of the raw carcass or processed meat. The extended shelf-life of foods is a response to the pandemic trend, whereby consumers are more likely to choose durable products that can be stored for a longer period between visits to food stores. This includes changing purchasing habits from “just in time” products “for now” to “just in case” products, a trend that will not fade away with the end of the pandemic. To address these concerns, novel carcass-decontamination technologies, such as ozone, high-pressure processing and cold atmospheric plasma, together with active and clean label ingredients, have been investigated for their potential applications in the meat industry. Processing parameters, such as exposure time and processing intensity have been evaluated for each type of matrix to achieve the maximum reduction of spoilage microorganism counts without affecting the physicochemical, organoleptic, and functional characteristics of the meat products. Furthermore, combined impact (hurdle concept) was evaluated to enhance the understanding of decontamination efficiency without undesirable changes in the meat products. Most of these technologies are beneficial as they are cost-effective, chemical-free, eco-friendly, easy to use, and can treat foods in sealed packages, preventing the product from post-process contamination. Interestingly, their synergistic combination with other hurdle approaches can help to substitute the use of chemical food preservatives, which is an aspect that is currently quite desirable in the majority of consumers. Nonetheless, some of these techniques are difficult to store, requiring a large capital investment for their installation, while a lack of certification for industrial utilization is also problematic. In addition, most of them suffer from a lack of sufficient data regarding their mode of action for inactivating microorganisms and extending shelf-life stability, necessitating a need for further research in this area.

“…Ozone is known to cause damage to different microbial cell components mainly cell membrane, proteins, lipids, and enzymes, which results in significant destruction of spoilage microorganisms and disease‐causing pathogens (Kaavya et al., 2021). Moreover, ozone efficacy is pronounced to a greater extent when the target microbes are suspended in an aqueous media or buffer with significantly low demand for ozone than the food matrix.…”

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.
