“…When comparing the effect of different light sources (incandescent, fluorescent, and LED RGB (red, green, blue)) on kale sprouts, LED lights resulted in the highest yield and the highest amounts of chlorophylls, β-carotene, lutein, neoxanthin, and ascorbic acid content [161]. Furthermore, compared to incandescent/fluorescent lighting, broccoli microgreens under high proportions of blue (20%) and red (80%) LED lighting accumulated a higher proportion of chlorophylls, carotenoids, glucoraphanin, and minerals [162].…”

With the growing interest of society in healthy eating, the interest in fresh, ready-to-eat, functional food, such as microscale vegetables (sprouted seeds and microgreens), has been on the rise in recent years globally. This review briefly describes the crops commonly used for microscale vegetable production, highlights Brassica vegetables because of their health-promoting secondary metabolites (polyphenols, glucosinolates), and looks at consumer acceptance of sprouts and microgreens. Apart from the main crops used for microscale vegetable production, landraces, wild food plants, and crops’ wild relatives often have high phytonutrient density and exciting flavors and tastes, thus providing the scope to widen the range of crops and species used for this purpose. Moreover, the nutritional value and content of phytochemicals often vary with plant growth and development within the same crop. Sprouted seeds and microgreens are often more nutrient-dense than ungerminated seeds or mature vegetables. This review also describes the environmental and priming factors that may impact the nutritional value and content of phytochemicals of microscale vegetables. These factors include the growth environment, growing substrates, imposed environmental stresses, seed priming and biostimulants, biofortification, and the effect of light in controlled environments. This review also touches on microgreen market trends. Due to their short growth cycle, nutrient-dense sprouts and microgreens can be produced with minimal input; without pesticides, they can even be home-grown and harvested as needed, hence having low environmental impacts and a broad acceptance among health-conscious consumers.

“…Ascorbic acid (AsA) level is an important quality parameter in kale crops (Fiutak & Michalczyk, 2020). According to Sikora and Bodziarczyk (2012), average Ascorbic acid content in kale is 62.3 mg/100 g. Results of the present experiment revealed that AsA content in the WZ was significantly (p<0.05) higher than that of the IZ and DZ (Figure 3).…”

“…The reduction in the AsA content in the DZ could be because of the lower light intensities experienced during the experimental period 13 due to the cloud cover. Fiutak & Michalczyk (2020) have demonstrated that a higher light intensity during the cropping period increases the content of AsA in plant tissues.…”

Curly kale (Brassica oleracea var. acephala) and Chinese kale (Brassica oleracea var. alboglabra) are cruciferous vegetables, which have recently gained great popularity in the world as a ‘superfood’. Generally, kale has the capacity to tolerate diverse climatic conditions while demanding fewer inputs, thus making it possible to cultivate them with a minimum cost for crop management. However, kale is still not widespread in Sri Lanka as a vegetable. Therefore, it has not been a commercialized crop to date. This study was conducted to explore the potential for cultivating kale in Sri Lanka. Two cultivars of curly kale (‘Dwarf green curled’ and ‘Winterbor F1’) and Chinese kale were cultivated in three agro-climatic zones representing three main climatic zones in the country, namely the Mid-Country Wet Zone, Mid country Intermediate Zone and Low-Country Dry Zone, using three different media (M1: Existing soil in each location; M2: Sand and coir dust mixture – ratio 1:1; M3: Sand, coir dust, and soil - ratio 1:1:1) at each location. The experiment was carried out as a three-factor factorial with three replicates as a pot experiment. Based on the present study results, even though all the varieties displayed a significantly (p < 0.05) higher growth in terms of dry matter accumulation in the Wet Zone, the growth in the other two locations was also found to be satisfactory. Dry matter accumulation was not significantly different among the varieties within each location. Different media did not have a significant influence on growth. Even though the antioxidant contents in all varieties varied among locations, the values were within the acceptable range. Therefore, both curly kale and Chinese kale can be successfully grown in the tested locations in Sri Lanka and can be easily introduced to local consumers as a ‘superfood’.

“…This combination of blue + red was also studied by Chen et al [58] in Chinese kale sprouts, who showed that 150 µmol m −2 s −1 R LEDs increased the development of kale sprouts and 150 µmol m −2 s −1 B LEDs enhanced the accumulation of glucosinolates in comparison with the same dose of white or blue + red combinations. In Fiutak et al's study [81], apart from obtaining the highest yield with cold and warm LEDs (even 10-fold low cost), regarding fluorescent lights and traditional bulbs, LEDs showed the highest amounts of chlorophylls, β-carotene, lutein, neoxanthin, thiocyanates, and ascorbic acid content in kale sprouts [81].…”

According to social demands, the agri-food industry must elaborate convenient safe and healthy foods rich in phytochemicals while minimising processing inputs like energy consumption. Young plants in their first stages of development represent great potential. Objective: This review summarises the latest scientific findings concerning the use of UV and visible spectrum LED lighting as green, sustainable, and low-cost technologies to improve the quality of sprouts, microgreens, and baby leaves to enhance their health-promoting compounds, focusing on their mode of action while reducing costs and energy. Results: These technologies applied during growing and/or after harvesting were able to improve physiological and morphological development of sprouted seeds while increasing their bioactive compound content without compromising safety and other quality attributes. The novelty is to summarise the main findings published in a comprehensive review, including the mode of action, and remarking on the possibility of its postharvest application where the literature is still scarce. Conclusions: Illumination with UV and/or different regions of the visible spectrum during growing and shelf life are good abiotic elicitors of the production of phytochemicals in young plants, mainly through the activation of specific photoreceptors and ROS production. However, we still need to understand the mechanistic responses and their dependence on the illumination conditions.
