Background Spices are susceptible to surface microbial contamination. Countries’ ban on ethylene oxide fumigation due to possible residual toxicity encouraged the usage of irradiation. Surface sterilization with low doses of ultraviolet radiation has been extensively researched as a safe, eco-friendly, and fast route. This study examines the quality of Apiaceae spices for consumption, including anise, fennel, caraway, and cumin, in response to germicidal ultraviolet radiation using a developed sterilization unit. Methods The influence of UV-C (254 nm, 10.5 mW/cm2) on the fungal and microbial count, germination percentage, respiration rate, phenolic content, essential oil, and the activity of antioxidant enzymes was investigated at exposure durations of 0–45 min in increments of 5 min. The treated seeds were packed in polyethylene bags in a naturally aerated storage room for 30 days before the inspection. Results The obtained data showed that UV-C stimulated seeds germination and increased respiration rate for all studied types. The 25 min of exposure exhibited the highest significant values compared to the control, considered a good indicator of seed vigor. In addition, UV-C exposure between 20 and 35 min promoted the accumulation of phenolic compounds and increased the oil content as a defense mechanism against radiation. Conversely, higher exposure to UV-C led to a significant reduction in phenolic and oil contents. Furthermore, the exposure to UV-C radiation enhanced the activity of antioxidant enzymes in terms of peroxidase and catalase, which progressively increased with increasing exposure durations, reached their peak at 25–30 min, and subsequently declined with extended exposure time was extended. In a similar pattern, exposure to UV-C radiation increased polyphenol oxidase activity to its highest level at 25 min, owing to the development of antioxidant protective mechanisms against oxidative stress. Conclusion UV-C irradiation in the range of 25–30 min is the most appropriate pretreatment to maintain the vitality of the examined seeds. Graphical Abstract

“…Experimental results depicted in Figure 2 show that an appropriate increase in CO 2 concentration inhibits respiration rate because CO 2 is a product of respiration and can interfere with the Krebs cycle enzymes at high concentrations, leading to decreased fruit metabolism (Martins et al, 2014). However, excess CO 2 induces anaerobic respiration (Poonsri, 2021;Junior et al, 2019), increasing the proportion of CO 2 release from fruits and vegetables. Moreover, because the energy conversion efficiency of anaerobic respiration is low, and large quantities of harmful substances are produced, this inevitably results in dry matter loss and increased cell inactivation, a decrease in water storage capacity, and an increase in the final weight loss rate.…”

To prolong the storage period of fresh Lilium longiflorum, maintain its quality during storage, and optimise the controlled atmosphere (CA) storage parameters. In a single-factor experiment, the temperature, humidity, and O2 and CO2 concentrations were considered as primary factors affecting the CA storage of L. longiflorum. Then, a comprehensive score was optimised using a back propagation neural network combined with empirical data. Finally, experimental verification was undertaken. The optimal concentrations of O2 and CO2 were 4.5% and 3.8%, respectively. A storage temperature of 4.2°C and a relative humidity of 90% were ideal. Under these conditions, the comprehensive evaluation score for L. longiflorum was 0.8424 (P > 0.05), consistent with the predicted value of 0.8372. Compared to ordinary cold storage, the storage period of L. longiflorum under these CA storage conditions was effectively prolonged. This provided an experimental basis for the CA storage of L. longiflorum.

“…Many studies have been carried out to prevent rotting and losses associated with poor handling and storage of strawberries, including cold storage [3,4], modified and controlled atmosphere storage [5][6][7], and radiation [8][9][10]. Studies have shown the effectiveness of these approaches in extending shelf life and inhibiting microbial growth; nonetheless, some adverse effects on flavor, anthocyanin content, organic acid, and vitamin C have been reported [11][12][13].…”

Background Strawberry fruit is a rich source of antioxidants that are beneficial for human health. However, the rapid decline of strawberries dramatically reduces the shelf life and raises postharvest losses. To develop an efficient and ecological approach for maintaining the quality, strawberries (Fragaria x ananassa, cv. Festival) were treated with 0.5% chitosan coating (0.5% Ch), guava leaf-based chitosan nanoparticles coating (Gl-ChNps), and a combination treatment of 1.3 mW/cm2 laser light followed by Gl-ChNps coating (combined treatment), then stored for 12 days at 10 °C and 85–90% RH. The untreated fruit served as a control. Results Semi-spherical particles with an average size of 21.92 nm, a monodisperse nature, and high solution stability were formed. The findings revealed that the combined treatment completely suppressed fungal decay compared to 50% decay in control, and significantly reduced weight loss percentage to 4.68% compared to 27.35% in control. In accordance, the combined treatment had the maximum anthocyanin content and vitamin C, at 42 and 81.1 mg/100 g, respectively. The results showed that treated strawberries had less change in color, total soluble solids, titratable acidity, and pH during storage than untreated strawberries, which exhibited higher chemical changes. Conclusions The edible film of chitosan nanoparticles acted as a semi-permeable barrier that modified and restricted gas exchange, reduced water loss, and delayed fruit senescence. In addition, the combination of laser light with chitosan nanoparticles has been shown to control the pathogens and retain the freshness of strawberries. Graphical Abstract
