“…An alternative to chemical treatment of harvested fruits is heat treatment. The processing technology involves hot water immersion (HWD), heating with saturated steam, hot dry air treatment, and hot water rinsing (HWR) with brushing [10].…”

“…The favorable effects of these heat treatments are the reduction of hypothermia and the slowing down of ripening processes due to thermal inactivation of degradation enzymes [11], the level of critical insect infestations and the onset of fungal decay [10]. Heat treatments can be short-term (up to 1 hour) or long-term (up to 4 days).…”

“…Hot water is a better energy carrier than air and provides a comparable reduction in fungal spoilage. Blue mold on grapefruit, caused by Penicillium sp., is controlled by immersing the fruit in hot water for 2 minutes at 50 °C [10]. It should be noted that, in addition to blue mold on the surface of lemon fruits, the most common and serious diseases are brown rot (Phytophthora), Alternaria rot (Alternaria tenuis Nees.…”

The problem solved is to determine safer and more effective technologies for post-harvest processing of fruits. To achieve the goal, lemon fruits (of different degrees of wilting) were cut crosswise, each piece was treated with miramistin and deсasan in concentrations of 0.1 %, 0.3 %, and 0.5 %. The samples were placed on agar blocks with pure cultures of pathogens and placed in wet Petri dishes, kept at a temperature of 25 °C in a thermostat for 6–10 days; the experiment was repeated three times. The research aimed to establish the concentration of antimicrobial drugs for treating lemons; determine the weight loss of lemon fruits depending on the storage temperature. The object of the study is the process of preserving the quality of lemon fruits during post-harvest treatment with antiseptics during cold storage. It is proposed to treat lemon fruits with miramistin and deсasan in concentrations of 0.3 % and 0.5 % in order to inhibit the development of blue and green mold during storage. Damage to turgor fruits is two times less than that of weakly wilted ones. At a storage temperature of 10 °C, fruits are stored for 40–45 days. At the same time, daily losses are 0.49 %. Lowering the storage temperature to 4 °C extends the storage period to 90–100 days, with a daily mass loss of 0.08 %. A curvilinear correlation dependence of the second order of weight loss of lemon fruits on the duration of storage was established (R2=0.9758–0.9903). Treatment with antiseptics makes it possible to implement environmentally friendly solutions that will make it possible to exclude chemically synthesized fungicides and preserve the natural properties of fresh citrus fruits after harvesting, as well as extend their shelf life. In the development of new, low-cost, environmentally friendly, and affordable technologies, this is an important technique

“…These losses occur due to limitations in fruit handling methods during classification, packing, storage, transportation, and marketing. Therefore, one of the main agents of damage is the presence of microorganisms, which significantly impact a product's quality [8,9]. Additionally, the inappropriate use of pesticides has increased by 30% in the last 20 years [10].…”

The effects of phytopathogenic fungi on fruits and vegetables are a significant global concern, impacting various sectors including social, economic, environmental, and consumer health. This issue results in diminished product quality, affecting a high percentage of globally important fruits. Over the last 20 years, the use of chemical products in the agri-food sector has increased by 30%, leading to environmental problems such as harm to main pollinators, high levels of chemical residue levels, development of resistance in various phytopathogens, and health issues. As a response, various organizations worldwide have proposed programs aimed at reducing the concentration of active compounds in these products. Priority is given to alternative treatments that can mitigate environmental impact, control phytopathogens, and ensure low residuality and toxicity in fruits and vegetables. This review article presents the mechanisms of action of three alternative treatments: chitosan, citral, and hexanal. These treatments have the potential to affect the development of various pathogenic fungi found in tropical and subtropical fruits. It is important to note that further studies to verify the effects of these treatments, particularly when used in combination, are needed. Integrating the mechanisms of action of each treatment and exploring the possibility of generating a broad-spectrum effect on the development of pathogenic microorganisms in fruits is essential for a comprehensive understanding and effective management.

The study targeted to compare the nutritional profile of two varieties of açaí, the white and purple, found in different mesoregions of Pará, Brazil. The research focused on analyzing levels of total phenolics, total anthocyanins, antioxidant capacity, and mineral composition in these two varieties. The study sought to identify significant differences between the two varieties in terms of nutritional composition and antioxidant potential, providing valuable information into the specific nutritional and functional properties of each type of açaí studied. Higher levels of total phenolics, total anthocyanins, and antioxidant capacity were observed in purple açaí fruits, with values of 806.17 ± 17.48 mgGAE/100 g, 81.73 ± 1.77 mg/100 g, and 19.25 ± 0.35 μmol of Trolox equivalent (TE)/g, respectively, compared to 401.92 ± 52.70 mgGAE/100 g, 37.70 ± 5.34 mg/100 g, and 6.17 ± 1.07 μmol TE/g in white açaí. HPLC-MS analysis identified and quantified monomeric anthocyanins in white açaí, using two distinct analytical methods, revealing average values of 0.29 and 1.05 μg/100 g for cyanidin-3-glucoside and between 0.74 and 3.13 μg/100 g for cyanidin-3-rutinoside, respectively, which were higher than those found in yellow tropical fruits. The quality of both purple and white açaí varied significantly among mesoregions, with fruits from floodplain soils demonstrating superior quality compared to those from sandy and solid soils in southeastern Pará. Mineral composition and microbiological characteristics were similar between white and purple açaí. These findings underscore the significant influence of mesoregion and soil type on açaí quality, emphasizing the superiority of fruits grown in floodplain soils.
