“…[ 95 , 96 , 97 ]. Similarly, BL was reported to increase the flavonoids contents, e.g., chalcone, naringenin, quercetin [ 95 ], kaempferol, rutin, (+)-catechin, (−)-epicatechin, cyanidin glucosides, and resveratrol [ 96 , 97 , 98 , 99 , 100 ], but also to reduce the content of rutin [ 99 ], quercetin, and other flavonoids [ 95 ]. During postharvest, RL and BL maintained the levels of different flavonoids, e.g., diosmin, hesperidin, didymin, neoeriocitrin, and narirutin [ 96 ].…”

“…There is evidence that LED lighting can influence the shelf life and quality of fresh produce, inhibiting weight loss, senescence, and over-ripening, and enhancing the production of antioxidant compounds [ 55 , 56 , 73 , 98 , 108 , 135 ]. Most of the results showed that BL promotes the accumulation of phytochemical constituents, including polyphenol in bananas ( Musa acuminate ) [ 100 ], Vit C in citrus juices ( Citrus unshiu and Citrus sinensis ) [ 72 ], Chinese cabbage ( Brassica campestris ) [ 75 ], and strawberry ( Fragaria ananassa ) [ 75 ], and anthocyanin in sweet cherries ( Prunus avium ) [ 84 ] and in Chinese bayberry fruit ( Myrica rubra ) [ 185 ]. In other studies, BL shows less effective results, compared to other light treatments.…”

Challenges and Opportunities of Light-Emitting Diode (LED) as Key to Modulate Antioxidant Compounds in Plants. A Review

Plant antioxidants are important compounds involved in plant defense, signaling, growth, and development. The quantity and quality of such compounds is genetically driven; nonetheless, light is one of the factors that strongly influence their synthesis and accumulation in plant tissues. Indeed, light quality affects the fitness of the plant, modulating its antioxidative profile, a key element to counteract the biotic and abiotic stresses. With this regard, light-emitting diodes (LEDs) are emerging as a powerful technology which allows the selection of specific wavelengths and intensities, and therefore the targeted accumulation of plant antioxidant compounds. Despite the unique advantages of such technology, LED application in the horticultural field is still at its early days and several aspects still need to be investigated. This review focused on the most recent outcomes of LED application to modulate the antioxidant compounds of plants, with particular regard to vitamin C, phenols, chlorophyll, carotenoids, and glucosinolates. Additionally, future challenges and opportunities in the use of LED technology in the growth and postharvest storage of fruits and vegetables were also addressed to give a comprehensive overview of the future applications and trends of research.

“…At present, the methods for improving the quality of sweet cherries after harvest mainly include low‐temperature storage (Zhao et al., 2019), 1‐MCP (Yang et al., 2011), modified atmosphere packaging (Cozzolino et al., 2019), coating film (Nabifarkhni et al., 2015), irradiation (Kokalj et al., 2019), and so on. Low‐temperature storage is a simple and feasible method among them, which can slow down the metabolic activities and inhibit the respiration rate.…”

The ozone fumigation device with the self‐circulation function and the low‐temperature fluctuation box with precise temperature control were, respectively, designed to study the effect of the combination of vacuum precooling with ozone fumigation or low‐temperature fluctuation treatment in the quality modifications of sweet cherries during cold storage. The results showed that all the three treatments had a positive effect on quality maintenance. Although precooling combined with low‐temperature fluctuation slightly damaged the fruit after 9 days of storage, the combination of precooling and ozone can better maintain the luster of the fruit and retain the content of total soluble solids, the titratable acid, and anthocyanin during the entire storage period. Meanwhile, it delayed fruit softening, inhibited the accumulation of malondialdehyde and activity of polyphenol oxidase. Additionally, the ultrastructure and cell wall material content indicated that ozone stress could induce shrinkage of stoma and maintain morphology of cell wall and cell structure. Practical applications Sweet cherries are delicious and juicy, but they have quite a short shelf life, limited edible period, and high cost of deep processing. Refrigeration, precooling, and ozone are effective measures to extend the shelf life of fruits and vegetables in the field of postharvest preservation. However, the large flow of personnel in the conventional walk‐in cold storage results in low precooling efficiency and significant temperature fluctuations, which make the cherries perishable. In addition, ozone has been evaluated as a promising disinfectant for fresh fruits, which may be used to induce resistance to postharvest decay of fruits and vegetables. Thus, in this study, a combination of precooling with ozone fumigation or low‐temperature fluctuation was used to explore the postharvest quality of sweet cherries. All results indicated that vacuum precooling combined with regular ozone fumigation treatment may be a promising technology for the preservation of sweet cherry fruit, which can effectively improve the storage quality.

“…Thus far, some advances have been achieved in determining the influence of light on fruit quality and related metabolites [5,6]. For example, ultraviolet C (UVC) and pulsed light treatments enhance the antioxidant properties of tomatoes [7], light-emitting diode (LED) irradiation promotes the accumulation of anthocyanins in sweet cherries [7,8], LED treatment induces ripening and improves the nutritional quality of postharvest banana fruit [9], and intense white light influences the carotenoid accumulation of developmental bilberry fruit, specifically responding to red/far-red light [10]. Even so, most of these studies only focus on investigating the effect of monochromatic light on fruit quality and related metabolites; few publications have reported on the use of polychromatic light, especially LED and UV light.…”

Mature ‘Hamlin’ sweet oranges (Citrus sinensis (L.) Osbeck) were irradiated using light-emitting diodes (LEDs) and ultraviolet (UV) light for six days after harvest. Based on evaluation of the basic ripening parameters of fruits, the contents of soluble sugars, organic acids, and carotenoids were analyzed (in pulps) on the sixth day by high-performance liquid chromatography (HPLC). The results showed that LED and UV irradiation not only accelerated orange ripening but also caused significant changes in the soluble sugar, organic acid, and carotenoid content. Compared with fruit subjected to dark shade (DS) treatment, the total soluble sugar, fructose, and glucose contents increased significantly in UV-treated (UVA, UVB, and UVC) fruits, while the sucrose content increased remarkably in white light, UVB, and UVC-treated fruits (p < 0.05). UV treatment was associated with inducing the largest effect on the total soluble sugar content. Except for UVB, other types of light notably induced an accumulation of the total organic acid content, none but blue light and red light markedly induced citric acid accumulation (p < 0.05). Interestingly, only the red light and dark shade treatments had markedly positive effects in terms of inducing carotenoid accumulation, including the total carotenoid, isolutein, zeaxanthin, lutein, neoxanthin, all-trans-violaxanthin, phytofluene, cis-ζ-carotene, and β-carotene concentrations. Other light treatments had significantly negative effects on carotenoid accumulation (p < 0.05). Therefore, soluble sugar, organic acid, and carotenoid accumulation in sweet oranges vary depending on the levels of UV and LED irradiation. Appropriate light irradiation is a potentially effective way to maintain or improve postharvest fruit quality.
