Special Issue Information

Dear Colleagues,

Fruits and vegetables are an important part of the human diet in both fresh and processed forms. Fruits and vegetables are perishable foods; therefore, it is necessary to preserve them from being lost as waste. In addition, during processing, a lot of fruits and vegetable go to waste. To overcome these issues or losses, advanced techniques are necessary. Furthermore, maintaining quality and minimizing agri-food loss can be possible through advances in harvesting, storage, packaging, and processing. For the advancements, AI and robotics can be used in smart and precision agriculture, advanced storage solutions for modification in control atmosphere and smart cold chains, innovation in packaging for smart packaging, edible coating and biodegradable edible film, and novel processing and preservation techniques, including high pressure processing, cold plasma, plus electric field and ultrasound. In the future, these advanced techniques can favorably reduce losses, enhance quality and safety, sustainability and integration.

The preservation of fruit and vegetable quality after harvest is a key challenge for the food industry, directly impacting food safety, nutritional value, and consumer acceptance. Conventional methods often fail to effectively mitigate post-harvest losses, requiring innovative approaches to extend shelf life and maintain the sensory and functional characteristics of these products. Advancements in post-harvest technologies, such as controlled atmosphere storage, edible coatings, ultrasound, cold plasma, and ozonation, have shown great potential in preserving quality and reducing waste. These innovations offer sustainable and effective alternatives, aligning with the growing demand for more natural and minimally processed foods.

This Special Issue aims to gather studies that explore novel approaches to post-harvest processing and their impacts on the quality, safety, and acceptance of fruit and vegetable products, fostering solutions to the challenges in this field.

The use of nanotechnology-based delivery systems along with growth regulators of plants is a promising approach to increase the quality of fruits postharvest. This experiment was aimed at determining the impact of sonicated nanoemulsions containing methyl jasmonate (MeJA) and 1-naphthaleneacetic acid (NAA) on the quality of postharvest Tango mandarin. The findings showed the samples treated improved fruit weight, diameter, firmness and juice percentage significantly compared to the control sample. TMJ4 (10.0 µM L−1) was the most effective treatment at preserving the fruit firmness, whereas TMJ3 (7.5 µM L−1) was the best treatment at improving the internal quality characteristics, such as total soluble solids, sugar–acid ratio, phenolics, flavonoids, flavonols, and antioxidant activity. Reduction in titratable acidity and a subsequent increase in sugar-to-acid ratio indicated a better maturation behavior and flavor profile of the fruit. The augmented retention of bioactive compounds implies the stimulation of secondary metabolite pathways and stress tolerance. The results suggest that nanoemulsion delivery of methyl jasmonate and NAA by sonication is an efficient method of enhancing the quality of the postharvest and prolonging the shelf life of Tango mandarin.

In this study, the effects of ozone treatment (O3), heat shock treatment (HS), and microwave treatment (MW) on sensory quality, physicochemical properties, and oxidation levels of sweet corn were systematically investigated during storage. The results demonstrated that three treatments prolonged the postharvest quality of sweet corn to varying degrees. Specifically, the O3 group demonstrated the best sensory and appearance characteristics, with its sensory score being 1.18 and 1.38 folds higher than the HS group and MW group, respectively, and significant retardation of color deterioration. In addition, the O3 group effectively maintained the stability and hardness of the starch structure. The weight loss rate of the HS group decreased 0.78-fold compared to the CT group after storage. Moreover, both HS and MW treatments maintained the antioxidant properties of sweet corn, but MW had the limitations of local scalding damage and accelerated deterioration in later quality. The results of this study provide a scientific basis for the optimization and application of postharvest preservation techniques for sweet corn. Full article
