Abstract
This study aimed to determine the effects of LED lights with different wavelengths on the growth parameters, fresh weight, and total antioxidant content of red cabbage microgreens (Brassica oleracea L. var. capitata subvar. rubra) grown under controlled conditions. The experiment was conducted using a fully automated plant growth chamber, named “Confetti Cabin”, with four light treatments: red LED, blue LED, red+blue LED, and a natural light control group. The study was designed with a randomized plot design and three replications. The highest stem length was observed under red LED light (59.28 mm), the highest fresh weight under red+blue LED (90.70 g), and the highest antioxidant content under blue LED (0.99 EC50 µg/mL). The findings suggest that light spectrum selection can be optimized based on production targets in microgreen cultivation.

Abstract
Microgreens are vegetable or edible herb shoots harvested in the early stages of development. They have an important number of bioactive compounds and add color, texture, and flavor to dishes and salads. Given their benefits, small size, and high market prices, they can grow in indoor systems, where light is determinant. This study aimed to evaluate the effect of different light intensities on agronomic characteristics, color, chlorophylls and carotenoids content, and antioxidant activity represented by total phenolic content (TPC), eliminate, and antioxidant capacity (AC) in four Brassicaceae species in two colors (green and red). The experiment was conducted in a controlled light-emitting diode (LED) environment growth chamber (day/night temperatures of 25/20 ± 1.2°C, 16 h photoperiod, and 79 ± 2% relative humidity). Three light intensities were used for microgreen growth with the same LED light spectrum: low (120 ± 5.1 μmol m −2 s −1 ), medium (160 ± 3.6 μmol m −2 s −1 ), and high (210 ± 5.9 μmol m −2 s −1 ). Eight g of the seeds of green and red cultivars of cabbage, kale, mizuna, and mustard were sown in a plastic tray (64 cm x 35 cm x 6 cm) with a mixture of peat and perlite (1:2 = v: v). Overall, the high intensity increased dry matter percentage and dry weight, except in green and red kale and green cabbage cultivars. In contrast, low intensity promoted a larger hypocotyl in all species than with high intensity; moreover, it enhanced the cotyledon area in green and red mizuna. Cabbage, kale, and mustard green cultivars were greener under medium intensity, whereas the low intensity enhanced the purple color of mizuna. In addition, chlorophyll a and b increased under low intensity in most species except the red kale and mustard cultivars. The high intensity raises the antioxidant activity, promoting a higher TPC and AC. The findings revealed that the light intensity generated variations in agronomic characteristics, color, chlorophyll content, and antioxidant activity of Brassicaceae microgreens, and the changes were based on the specific species and cultivars.

Abstract
Light spectrum and intensity is one of the key factors in the production of microgreens in controlled-environment agriculture and is directly related to plant growth and biomass accumulation. Hence, the objective of this research study was to investigate the biomass, growth, and resource use efficiencies (RUEs) in 14 different species of microgreen grown in two light recipes with 209.5 (OSRAM LED) and 45 µmol m−2 s−1 (INSTAGREEN LED) with a 16/8 h light/dark photoperiod in a growth chamber. Under both LEDs, fresh biomass accumulation and the SPAD content were highest in sunflower. Nasturtium recorded the maximum hypocotyl length under both LEDs. The leaf area index (LAI) was significantly higher in mungbean under the INSTAGREEN LED compared to other microgreens, while the maximum LAI was measured in lentils under the OSRAM LED. This shows that the two different LEDs had species-specific effects. The RUE of the cheaper INSTAGREEN LED was more efficient in terms of light and energy use efficiency, while OSRAM LED was more efficient in terms of water and surface use efficiencies. Overall, the results showed that different species of microgreens exhibit different responses to fresh biomass accumulation and SPAD contents in the leaves, demonstrating the diversity of their growth responses. Across both LEDs (OSRAM LED and INSTAGREEN LED), the top performing microgreen in terms of biomass accumulation as well as SPAD contents in the leaves was sunflower. Consequently, a high chlorophyll content in sunflower led to a higher biomass production by enhancing photosynthesis.

Abstract
Microgreens are functional foods whose nutritional content varies depending upon the production methods used when grown. Consumers may perceive different microgreen production practices as carrying varying levels of risk. Here, an online survey of 820 Tennesseans indicated their perceived risk of consumption and environmental impacts for nutritionally enhanced microgreens grown using eight different production methods (e.g., plant breeding, gene editing, lighting, etc.). Probit models were used to analyze data. Results demonstrate that the different production methods were associated with different risk perceptions. Species selection and lighting were perceived as the safest practice for consumption and the environment. Gene editing and genetic modification were perceived as the least safe for consumption and the environment. Production strategies selected as the best option to enhance nutrition improved perceptions of production practice safety. Existing subjective knowledge of the production methods positively influenced consumers’ safety perceptions. Gender, education and urban residency all impacted perceived risk but varied by production method. Given the heightened interest in nutritious food and environmental health, it is important to understand how consumers perceive different production methods to better inform them about their food choices and encourage sustainable consumption behaviors. In turn, results can aid growers, retailers and other stakeholders as they consider alternative production methods and marketing strategies. – Consumers perceived risk for production practices to enhance microgreen nutrient content vary. – Species selection and lighting were perceived as “safest” for consumption and the environment. – Gene editing and modification were perceived as the “least safe”.

Abstract
Many people suffer from a deficiency of essential micronutrients. Sprouts and microgreens can transform the whole idea of vegetables to resolve the need for a diet with fresh, nutrient-rich, and high content of phyto-compounds necessary for a healthy body. The study’s main objective is to evaluate the growth of 6 different seeds, such as four legumes; fenugreek, mung bean, cowpea, horse gram and two grains, wheat, sorghum microgreens. All the seeds were cultivated in soil, water and coco peat, to estimate and compare the nutritional properties of the selected sprouts vs. microgreens. The growth of microgreens in each medium was evaluated, and the proximate and nutritional properties were analysed. In terms of the growth of microgreens, coco peat medium serves the best, as it retains water for a long and it is porous to provide better aeration for the roots and also the day of harvest is shorter. In terms of the nutritional property of microgreens, soil serves the best, as it contains more nutrients than any other medium. The study results showed sprouts are better sources of proteins and carbohydrates than microgreens. However, microgreens were characterized by a high content of carotenoids, chlorophylls and ascorbic acid. It also exhibiting higher anti-diabetic and anticholinergic activity than sprouts. In addition, the microgreens have more micronutrients like zinc, copper, iron, magnesium, potassium etc., than the sprouts. Finally, microgreens were better growing with coco peat and also sources for functional components for dietary supplements and sustainable agriculture.

Abstract
Microgreens are young plants of various vegetables, medicinal and aromatic plants, cereals and edible wild plants that were first associated with nouvelle cuisine as decoration in dishes due to their attractive appearance and strong flavor. Recently, they have become more sought after in the market due to their high nutritional value. This is due to the growing interest of consumers in a healthy lifestyle that includes a varied diet with emphasis on fresh, functional foods. Nowadays, commercial production of microgreens is shifting to modern hydroponic systems due to their numerous advantages, such as accelerated plant growth and biomass production, earlier harvesting, and more production cycles that positively affect yield and chemical composition. Therefore, the aim of this study was to determine the content of specialized metabolites and antioxidant capacity of hydroponically grown alfalfa (Medicago sativa) cv. ‘Kangaroo’, yellow beet (Beta vulgaris var. conditiva) cv. ‘Yellow Lady’, red cabbage (Brassica oleracea L. var. rubra) cv. ‘Red Carpet’, and fennel (Foeniculum vulgare) cv. ‘Aganarpo’ microgreens. The highest content of total phenols (408.03 mg GAE/100 g fw), flavonoids (214.47 mg GAE/100 g fw), non-flavonoids (193.56 mg GAE/100 g fw) and ascorbic acid (74.94 mg/100 g fw) was found in fennel microgreens. The highest content of all analyzed chlorophyll pigments (Chl_a 0.536 mg/g fw, Chl_b 0.248 mg/g fw, and TCh 0.785 mg/g fw) was found in alfalfa microgreens. However, in addition to alfalfa, high levels of chlorophyll a (0.528 mg/g fw), total chlorophyll (0.713 mg/g fw) and the highest level of total carotenoids (0.196 mg/g fw) were also detected in fennel microgreens. The results suggest that microgreens grown on perlite in floating hydroponics have high nutritional potential as a functional food important for human health and therefore could be recommended for daily diet.

Abstract
Oxidative stress and inflammation play a role in cognitive impairment, which is a core symptom of schizophrenia. Furthermore, a hallmark of the pathophysiology of this disease is the dysfunction of cortical inhibitory γ-aminobutyric acid (GABA) neurons expressing parvalbumin (PV), which is also involved in cognitive impairment. Sulforaphane (SFN), an isothiocyanate derived from broccoli, is a potent activator of the transcription factor Nrf2, which plays a central role in the inducible expressions of many cytoprotective genes in response to oxidative stress. Keap1 is a cytoplasmic protein that is essential for the regulation of Nrf2 activity. Here, we found that pretreatment with SFN attenuated cognitive deficits, the increase in 8-oxo-dG-positive cells, and the decrease in PV-positive cells in the medial prefrontal cortex and hippocampus after repeated administration of phencyclidine (PCP). Furthermore, PCP-induced cognitive deficits were improved by the subsequent subchronic administration of SFN. Interestingly, the dietary intake of glucoraphanin (a glucosinolate precursor of SFN) during the juvenile and adolescence prevented the onset of PCP-induced cognitive deficits as well as the increase in 8-oxo-dG-positive cells and the decrease in PV-positive cells in the brain at adulthood. Moreover, the NRF2 gene and the KEAP1 gene had an epistatic effect on cognitive impairment (e.g., working memory and processing speed) in patients with schizophrenia. These findings suggest that SFN may have prophylactic and therapeutic effects on cognitive impairment in schizophrenia. Therefore, the dietary intake of SFN-rich broccoli sprouts during the juvenile and adolescence may prevent the onset of psychosis at adulthood.

Abstract
Escalating public health concerns necessitate innovative approaches to food sources. Microgreens, nutrient-rich seedlings of vegetables and herbs, have gained recognition as functional foods. This review explores the evolution of microgreens, cultivation methods, biochemical changes during germination, nutritional content, health benefits, and commercial significance. Comprehensive studies have demonstrated that microgreens have an elevated level of various nutrients. Further, in vitro and in vivo research validated their antioxidant, anticancer, antibacterial, anti-inflammatory, anti-obesity, and antidiabetic properties. Microgreens, termed “desert food,” show promise for sustainable food production in climate-vulnerable regions. This paper synthesizes recent research on microgreens, addressing challenges and gaps in understanding their nutritional content and health benefits. It contributes valuable insights for future research, fostering sustainable agriculture and enhancing understanding of microgreens in human health and nutrition.

Abstract
Selecting suitable crop species is crucial for optimizing the productivity and nutritional content of microgreens. In this study, twenty-three diverse microgreen species, grown under controlled conditions, were analyzed for yield, bioactive compounds, and antioxidant activities. The microgreens were cultivated on a peat substrate in a controlled environment, with a growth period of 6 to 20 days from planting to harvest. Conditions were maintained at 25 ± 2 °C, a 16 h photoperiod, CO2 concentration of 1000 ppm, relative humidity of 60 ± 2%, and the LED light was set at 330 μmol/m2/s PPFD. Results from the analysis revealed that the yield, bioactive compounds, and antioxidant potential differed significantly among the twenty-three microgreen species. Unfortunately, the superior microgreens exhibiting greater values for all studied traits could not be identified. However, the principal component analysis (PCA) clustered red radish, rat-tailed radish, and Chinese kale microgreens, which were high in both yield and bioactive compounds. In contrast, red holy basil and lemon basil microgreens had high levels of these compounds but low yields. Additionally, a high level of anti-tyrosinase activity was observed in garland chrysanthemum, Chinese mustard, and Chinese cabbage microgreens. Therefore, these microgreen species can be utilized individually or in varying ratios to produce bioactive compounds in different concentrations that are suitable for various applications. The information presented in this study provides valuable insights for health-conscious consumers and growers for selecting superior species with functional implications.

Abstract
AIMS: Nutrition and dietetics students are future change agents for sustainable food systems, yet sustainability education remains limited in university curricula. This study evaluated the impact of an experiential learning activity using an indoor aquaponic system on students’ knowledge, attitudes and behavioural intentions towards sustainable diets. METHODS: An embedded mixed methods pre-post survey captured baseline data on students’ sustainable diet knowledge, attitudes and behaviours, alongside diet quality (using the Australian Recommended Food Score). Students then participated in an interactive experiential learning activity involving an indoor aquaponic system. Post-activity surveys assessed changes in knowledge and behaviour intentions, as well as perceptions of the learning experience. Quantitative data were analysed using chi-square tests, regression and McNemar-Bowker tests; qualitative responses were thematically analysed. RESULTS: At baseline, students (n = 58, 87.9% female) reported limited knowledge of local food systems, though most valued sustainable food practices. Students who placed high importance on sustainable diets were significantly more likely to engage in sustainable dietary behaviours. Diet quality was significantly higher among students who grew their own food, bought locally or purchased seasonal produce (all p < 0.05). Participation in the experiential learning activity significantly improved students’ self-reported knowledge of local food systems (p < 0.001) and increased their intentions towards buying locally-grown (57.9% to 86.8%, p < 0.001) and growing food (36.8% to 78.9%, p < 0.001). Thematic analysis highlighted students’ increased awareness of sustainability complexity, their role as nutrition professionals and the importance of curriculum integration. CONCLUSION: Experiential learning with an indoor aquaponic system enhanced students’ knowledge and intentions related to sustainable diets. Students who engaged in sustainable behaviours had significantly higher diet quality, highlighting the potential dual benefit of curriculum integration. Embedding sustainability-focused learning in nutrition curricula may better prepare students to lead change in food systems.

Abstract
Microgreens are gaining more and more interest, but little information is available on the effects of the chemical composition of the nutrient solution on the microgreen yield. In this study, three Brassica genotypes (B. oleracea var. italica, B. oleracea var. botrytis, and Brassica rapa L. subsp. sylvestris L. Janch. var. esculenta Hort) were fertigated with three modified strength Hoagland nutrient solutions (1/2, 1/4, and 1/8 strength) or with three modified half-strength Hoagland nutrient solutions with three different NH4:NO3 molar ratios (5:95, 15:85, and 25:75). Microgreen yields and content of inorganic ions, dietary fiber, proteins, α-tocopherol, and β-carotene were evaluated. Micro cauliflower showed the highest yield, as well as a higher content of mineral elements and α-tocopherol (10.4 mg 100 g−1 fresh weight (FW)) than other genotypes. The use of nutrient solution at half strength gave both a high yield (0.23 g cm−2) and a desirable seedling height. By changing the NH4:NO3 molar ratio in the nutrient solution, no differences were found on yield and growing parameters, although the highest β-carotene content (6.3 mg 100 g−1 FW) was found by using a NH4:NO3 molar ratio of 25:75. The lowest nitrate content (on average 6.8 g 100 g−1 dry weight) was found in micro broccoli and micro broccoli raab by using a nutrient solution with NH4:NO3 molar ratios of 25:75 and 5:95, respectively. Micro cauliflower fertigated with a NH4:NO3 molar ratio of 25:75 showed the highest dry matter (9.8 g 100 g−1 FW) and protein content (4.2 g 100 g−1 FW).

Abstract
Cancer is a major public health concern worldwide responsible for high morbidity and mortality rates. Alternative therapies have been extensively investigated, and plant-derived compounds have caught the attention of the scientific community due to their chemopreventive and anticancer effects. Sulforaphane (SFN) is one of these naturally occurring agents, and studies have shown that it is able to target a specific cancer cell population displaying stem-like properties, known as cancer stem cells (CSCs). These cells can self-renewal and differentiate to form highly heterogeneous tumor masses. Notably, most of the conventional chemotherapeutic agents cannot target CSCs once they usually exist in a quiescent state and overall, the available cytotoxic drugs focus on highly dividing cells. This is, at least in part, one of the reasons why some oncologic patients relapse after standard therapy. In this review we bring together studies supporting not only the chemopreventive and anticancer properties of SFN, but especially the emerging anti-CSCs effects of this natural product and its potential to be used with conventional antineoplastic drugs in the clinical setting.
