Microgreens share many characteristics with sprouts, and while they have not been associated with any foodborne illness outbreaks, they have recently been the subject of seven recalls. A 2010 study published in the Journal of American Society for Horticultural Science reported that young lettuce seedlings, harvested 7 days after germination, had the highest antioxidant capacity as well as the highest concentrations of health-promoting phenolic compounds, compared with their more mature conterparts. (2015b) found that UV‐A irradiation supplemental to basal LED illumination was generally able to improve antioxidant properties of basil, beet, and pak choi microgreens at 12.4 µmol m−2 s−1 with some wavelengths benefitting particular antioxidant components. However, these microgreens still need to be used quickly to maintain peak quality. This information provides an incentive to incorporate sprouts and microgreens into my diet. Berba and Uchanski (2012) suggest that microgreen shelf life may be influenced by the age of the seedlings at harvest. During seed germination, the seed releases a mixture of carbohydrates and peptides that can attract surrounding bacteria in the rhizosphere. Microbial counts on microgreens washed in 50–100 mg/L chlorine declined initially but rebounded and far exceeded unwashed microgreens by the end of the 21 day storage. Klopsch et al. There is a lot of information out there about how microgreens have a lot of nutrition. Depending on cultivar and storage conditions, quality may be maintained for over 14 days. Once grown you can store the microgreens at 38-40 degrees in a closed air-tight container. Microgreens are difficult to store, due to their high surface area to volume ratio, high respiration rate, and delicate leaves that easily wilt, and rapid postharvest decay transpiration, leakage of nutrient rich exudates, tissue damage, and early senescence (Berba & Uchanski, 2012; Chandra, Kim, & Kim, 2012; Kou et al., 2013). Sprouts, Microgreens, Container Gardening, Nutrition & Mindfulness Practices. They also found that potato, carrot and pepper disks coinoculated with S. enterica serovar Typhimurium and Erwinia carotovora (since renamed Pectobacterium carotovorum) supported 10‐fold higher Salmonella populations than produce inoculated with Salmonella alone. The Brassica vegetables, in particular, contain compounds that may protect against cancer (Herr & Büchler, 2010) including glucosinolates (Fuentes, Paredes‐Gonzalez, & Kong, 2015), carotenoids (Niranjana et al., 2015; Nishino, Murakoshi, Tokuda, & Satomi, 2009), and selenium (Donaldson, 2004). However, S. enterica growth on seed‐inoculated alfalfa sprouts was also affected by seed storage time, while on Swiss chard microgreens it was dependant on serovar. of Egyptian spinach microgreens increased under blue and natural light. Since microgreen tissues are more delicate than mature tissues, the wrinkling observed may be damage caused by radiation exposure under SEM. vetstud / Originally Posted in Antioxidants Sprouting Up Answer: USDA researchers recently published a study assessing the nutrition content of 25 commercially available microgreens, seedlings of vegetables and herbs that have gained popularity in upscale markets and restaurants. At 6 days, the bacteria were found in stems and leaves. Containers or flats used to grow microgreens should be sanitized prior to reuse. The intention of this review is to fit together these pieces and bring attention to the areas that are potential impediments to commercialization. Microgreens are salad crop shoots harvested for consumption within 10 - 20 d of seedling emergence. How do you know which microgreens have what nutrition and benefits? However, others, like radish and broccoli seeds, have been implicated in microgreen recalls. (2001) also noted that higher concentrations of Serratia marcescens were seen at 3 days after inoculation near emerging lateral roots of rice seedlings, again indicating a potential site of ingress for bacteria into plants. Yang, Luo, Millner, Turner, and Feng (2012) further investigated the impact of cutting method, cutting blade, and coring blade on pathogen transference in different soil types and at different inoculum levels.

We carefully review (or use) each product we share with our visitors and customers. A final field of research that has not been specifically explored is new uses, e.g. April 23, 2020 April 23, 2020 / Marlo / Leave a comment. This movement is driven by population growth, shrinking arable land, and the need for ensuring food security (Goodman & Minner, 2019; Stoleru, Ionitᾰ, & Zamfirache, 2016; Wood, 2019). There are many postharvest treatments that have been explored for other produce items that may help to maintain quality and extend shelf life of microgreens. Worker training and skill could greatly impact the safety of harvested produce (Yang et al., 2012). I’d been sharing my thoughts about microgreens nutrition with my neighbor Doug, and yesterday we were on our daily walk when he asked me, “how much microgreens to eat per day?” That’s an excellent question, I thought. What are microgreens, and why should you eat them? Microgreens are an emerging class of produce that have gained increasing popularity (Kyriacou et al., 2016; Pinto, Almeida, Aguiar, & Ferreira, 2015; Xiao, Lester, Luo, & Wang, 2012). Light quality affects many aspects of plant growth, morphology, color, flavor, and nutrition (Kyriacou et al., 2016). Because they never reach maturity, microgreens can contain from 4 to 40 times more nutrients than the mature plants they were meant to grow into. • Microgreens are a close cousin of sprouts. So, if you’re planning to add some extra nutrition to your diet, microgreens are the way to go. They are the seedlings of edible plants harvested 7–14 days postplanting when the first true leaves start to emerge. However, all postharvest wash treatments caused quality degradation compared to samples receiving preharvest calcium chloride treatment only (Kou et al., 2015). If you do not receive an email within 10 minutes, your email address may not be registered, Although the pathogens were able to proliferate in both production systems, they were significantly (3–5 log cfu/g) higher on sprouts than on microgreens. Abstract Microgreens have gained increasing popularity as food ingredients in recent years because of their high nutritional value and diverse sensorial characteristics. Microgreens are tiny versions of vegetables and herbs – items like radish, kale and red cabbage that have not yet hit maturity. 100 grams. For example, for patients with impaired kidney function requiring a low potassium diet, the nutrient solution used can be prepared with low or no potassium (Renna, Castellino, Leoni, Paradiso, & Santamaria, 2018). Microgreens have 2-3.5 times more nutrients than mature spinach leaves! Microgreens are not subject to these requirements. (2017) reported lower microbial populations in recycled fiber mats and on microgreens growing on them than in peat‐based mixes and microgreens grown in peat. They observed significant colonization of lateral root cracks, suggesting that this may be the site of entry for these bacteria. (2013) profiled polyphenols in five microgreen cultivars of the genus Brassica and found 165 phenolic compounds comprising many highly glycosylated and acylated quercetin, kaempferol, cyanadin aglycones, and complex hydroxycinnamic and benzoic acids. However, it accelerated fresh weight loss after 5 days storage. However, they are immature when consumed and affected by physiological differences that make the young plants more vulnerable to human pathogen colonization and internalization (Warriner, Ibrahim, Dickinson, Wright, & Waites, 2003). Cutting implements used to harvest microgreens should also be sanitized between flats, and care should be taken to avoid their contact with growth medium. (2016) found that red cabbage microgreen supplementation had health‐promoting effects in mice fed a high fat diet. (2011) found that different supplemental LED wavelengths in addition to the basal components of blue (455 nm), red (638 nm), deep red (669 nm), and far red (731 nm) had different effects on the antioxidant compounds in sprouted seeds. Mechanization of the harvesting can reduce the need to handle microgreens, and education can improve worker hygiene practices. vegetable nitrate limitations in rocket greens can be a challenge (Bulgari et al., 2017). Wright and Holden (2018) did not test STEC growth/survival on microgreens grown in soil substitute. Microgreens are "tasty with this sharp spice, that taste in the back of your mouth that you're not accustomed to." Samuolienė et al. Additionally, food safety concerns are paramount for astronauts who have limited access to medical treatment during space travel and are confined together in a small space. Garrido, Tudela, Hernández, and Gil (2016) found that MAP during both continuous light and dark conditions caused physiological degradation of spinach leaves. Zero-Point Organics is a passionate producer and grower of the most unusual, flavorful and beautiful microgreens and edibles for serious foodies who crave big, bold flavors grown with care. Removing excess moisture after washing without causing damage is a challenge. (2014a) found that light exposure accelerated deterioration of radish microgreeens, while dark‐storage maintained quality. baby arugula . On the other hand, lessons learned from sprouts indicate that effective seed decontamination without hampering seed viability can be challenging. #microgreen #Microgreens #growyourownfoods #growmyownfood #nongmo #growfromseeds #growityourself #growsomething #sustainableliving #indoorgrowing #hydroponic … Broccoli and mustard showed the lowest and highest BF values, respectively, for potassium and magnesium, while kale had the highest BF value for calcium (de la Fuente et al., 2019). It also has a mild flavor that makes it easy to pair with a variety of fruits and vegetables or … Just a few inches tall, they boast intense flavors and vivid colors, but what about their nutritional Most vegetables are high in a wide range of vitamins and minerals to begin with. Chevril Microgreens. Some of the seeds for sprouting, for example, alfalfa and clover, are not typically grown for microgreens. If microbial contamination is present on seeds or production equipment, or introduced by insects or lack of hygienic practices by workers, rapid growth of microbes will ensue, resulting in contamination of the entire batch. Temperature is the most important environmental factor that influences quality and shelf life of harvested produce (Kader & Rolle, 2004). Also, It makes a great salad base and often used in juicing or to complementing the smoothies. Microgreens. ... spinach, amaranth, beets, swiss chard, orach, and magenta spreen: ... nutrition, and food safety of microgreens has not been assessed. Seed coats, roots, and cotyledons were most heavily contaminated. That adage is certainly true when it comes to microgreens. Nevertheless, it is obvious that microgreens are excellent sources of phytonutrients. Huang et al. In our previous unpublished research, Ruby radish microgreens washed in 100 ppm chlorine and dried centrifugally at 300 rpm maintained better visual quality and lower electrolyte leakage until day 12 than unwashed ruby radish microgreens. One major limitation to the growth of the microgreen industry is rapid quality deterioration postharvest. • Microgreens can boost color, enhance flavor, and add texture to any dish, while delivering a nutritional boost as well. Growing food in space holds many challenges with regard to microgravity including seed germination, watering plants, and anchoring plant roots, as well as limited resources. Sanitation of equipment used for handling and transporting produce prevents cross‐contamination and is equally important for preventing infection from both spoilage and pathogenic microorganisms. I help people just like you achieve lasting health without the treadmill of diet fads and pills, by providing the most up-to-date information on microgreens and nutritious plant-based recipes from across the world. of Nutrition and Food Science, Univ. While overall temperature and nighttime temperature may affect nutrient content of mature plants (Burbott & Loomis, 1967; Steward et al., 1959), no work has been published on the effect of temperature or intermittent temperature treatments on microgreen nutrition. 1.5M ratings 277k ratings ...

Visit Bootstrap Farmer today to learn more! These include treating seeds for decontamination, taking measures to prevent introduction of pathogens into or onto seeds used for sprouting, testing spent sprout irrigation water, testing the growing, harvesting, packing, and holding environment, documenting all treatments and testing, and taking corrective actions if samples are found positive (U.S. FDA, 2015). Most research on microgreens has taken place in the last 7 years by a limited but growing number of international research groups (Brazaitytė et al., 2018; Craver, Gerovac, Lopez, & Kopsell, 2017; Kyriacou et al., 2016; Riggio, Wang, Kniel, & Gibson, 2019b; Xiao et al., 2012). (2018) reported that the type of growth medium played an important role in serovar‐dependant Salmonella survival and growth on microgreens irrigated with contaminated water. And whether they're spinach, pea, beet or purple mustard, microgreens are rumored to pack even more nutrients that their adult versions. Microgreens share many characteristics with sprouts, and have been associated with seven recalls in the United States and Canada; three due to Salmonella (Canadian Food Inspection Agency [CFIA], 2018a; Clark, 2017; Marler, 2016), and the other four due to Listeria contamination (CFIA, 2018b, CFIA, 2019; U.S. Food and Drug Administration [FDA], 2018; Whole Foods Market, 2018). All supplemental wavelengths increased total carotenoid content in mustard but decreased it in red pak choi (Brazaitytė et al., 2015a). If you find their taste too overwhelming at first, just remember that a little bit goes a long way. Acquisition of needed research is likely hampered by the small scale, local nature of microgreen cultivation. Spinach microgreens are so intensely flavorful that a handful go a long way. Microgreens are harvested by cutting the stem above the root and are consequently highly perishable depending on the species (Berba & Uchanski, 2012). The U.S. FDA (1999) recommended that all seed destined for sprout production should be treated with one or more treatments (such as 20,000 ppm calcium hypochlorite) that have been approved for reduction of pathogens in seeds or sprouts. The estimated time to harvest is 8-12 days, and your microgreens will be a darker shade of green. Riggio et al. (2003) reported that microgreens are more vulnerable to bacterial internalization than mature vegetable plants and described how bacteria present in seeds can become part of the endophytic microflora. No formal studies in the literature were found on harvest age effects on shelf life of microgreens. Nutrition Fact 3: Many Microgreens Are Loaded With Beta-Carotene. Potentially effective methods for microgreen harvest are application of a very sharp shear force that cauterizes the wound simultaneously such as a laser or heated wire. Overall, this study provided critical information useful in selecting microgreens for wholesome nutrition. Chilling sensitivity, while genetic, is affected by other factors including growth stage and package atmosphere composition (Kyriacou et al., 2016). Their cultivation most closely resembles sprout production; they are cultivated in controlled environments, thereby avoiding potential field sources of contamination (Barak & Schroeder, 2012). Ruby radish microgreens also had the greatest DPPH radical scavenging capacity. Cauliflower, rapini, red radish, China rose radish, and ruby radish microgreens were found to have the greatest contents of total ascorbic acid, phylloquinone, total tocopherols, total glucosinolates, and TPC, respectively. Refrigeration and packaging are essential to maintain quality. There are no food code requirements for microgreens, but preliminary studies suggest that microgreens should be stored at temperature's of ≤5 °C (Kou et al., 2013; Xiao et al., 2014b). Spinach. 200 grams. Spinach, lettuce, basil: 5 facts about microgreens that'll hook the health buff in you It turns out that these small microgreens are capable of doing much more than their tiny weight and appearance. Microgreens ist ein Begriff, der aus Amerika zu uns herüber schwappt und immer größere Wellen schlägt. Application of blue (470 nm; 41 µmol m−2 s−1) LED light 5 days prior to harvest resulted in significant increases in carotenoids, glucosinolates, and micro‐ and macromineral elements in broccoli microgreens compared to a combination of red (627 nm; 88%) and blue (470 nm; 12%) LED lights with average light intensity of 350 µmol m−2 s−1 (Kopsell & Sams, 2013). Our tender baby arugula bursts with peppery flavor second to none. They reported more complex polyphenol profiles and a greater variety of polyphenols in the microgreens than in their mature plant counterparts. Analysis of 30 cultivars of microgreens of the family Brassicaceae revealed that Brassica microgreens are good sources of the macroelements, K and Ca, and the microelements, Fe and Zn (Xiao et al., 2016). Eat spinach leaves? You're in the right place. 1. Here are 14 of the healthiest leafy green vegetables you should eat. However, hydroponically grown microgreens may result in safety concerns similar to those of sprouts due to the humid conditions and constant warm temperatures. (2013) recommended 400–600 µmol m−2 s−1 PPFD to optimize above‐ground biomass for hydroponic lettuce production using red, blue, and white LEDs. Microgreens have gained increasing popularity as food ingredients in recent years because of their high nutritional value and diverse sensorial characteristics. advertisement While 1‐methylcyclopropene (1‐MCP) has been found to be an effective treatment to prolong shelf life of a wide variety of fruits and vegetables and edible flowers, it has not, to our knowledge, been tested on microgreens. Beetroot microgreens have a mild, spinach-like flavour. Carrot Microgreens. The plant hormone ethylene induces a wide range of physiological responses in horticultural crops including abscission, ripening and senescence, chlorophyll loss softening, physiological disorders, discoloration, decay and stimulation of defense systems (Saltveit, 1999). The Amaranthaceae, Apiaceae, and Lamiaceae are also health beneficial, and plants in the Alliaceae and Lamiaceae also produce antimicrobial compounds. There is a vast amount of territory yet to be explored. Additionally, microgreens of the family Brassicaceae were found to be moderate to excellent sources of ascorbic acid, phylloquinone, carotenoids, tocopherols, glucosinolates, and polyphenols (Xiao et al., 2019). Plants are highly valued in space to regenerate oxygen, fix nitrogen, provide vital nutrients and fresh ingredients, and to enhance morale of astronauts during extended stays away from Earth (Kyriacou, De Pascale, Kyratzis, & Rouphael, 2017). Spray the plants thoroughly two hours before you intend to harvest them. Each group has focused on a narrow subset of microgreens and their issues. Most of these factors are also important in maintaining produce safety. Lyon brightens up dishes like seared scallops, tomato soup, and salads with his favorite microgreens, which are basil, cilantro, onion, and beet. TPC and total anthocyanins were maximized in basil for blue (470 nm) and red (627 nm) at a frequency of 1024 Hz, and TPC was also maximized in basil for blue (455 nm) at 256 Hz (Vaštakaitė et al., 2018). However, in immature plants protective structures are not fully formed, enabling entry of bacteria into xylem (Warriner et al., 2003). An assortment of colors, visual textures, aromas, and flavors give appeal to these tender young greens pictured in Fig. The authors suggested that the same seed pregermination treatments required for growing sprouted seeds should be taken for microgreens, at least those grown in hydroponic systems. In the absence of ethylene, 1‐MCP treatment only increased shelf life for mizuna and tatsoi (21 and 67% increase, respectively). In contrast, 1‐MCP treatment in the presence of ethylene significantly protected Chinese mustard, choy sum, garland chrysanthemum, and tatsoi (Able et al., 2003). Seeds have been found to be the main source of pathogens responsible for sprout‐related foodborne illness outbreaks (Fett, 2006; Yang et al., 2013). The benefits of green leafy vegetables are well-known. In particular, this treatment increased the levels of β‐carotene, violaxanthin, glucoraphanin, K, Mg, and Fe. Of the different growth media tested, hydroponic pads resulted in the highest percentage of Salmonella‐positive samples and the highest Salmonella population level on microgreens. A 12‐hr photoperiod treatment resulted in less discoloration than the constant light treatment and less tissue injury than the constant dark treatment, but still did not score well on quality. The greatest “shelf life” of microgreens is achieved by selling them still rooted in the growth medium. Total phenolic content (TPC) increased in all microgreens except for amaranth; total ascorbic acid content increased in amaranth, kale, broccoli, mustard, and pea and declined in basil and borage microgreens; total anthocyanins increased in amaranth, kale, broccoli, tatsoi, and pea and declined in mustard, borage, beet ,and parsley microgreens (Samuolienė et al., 2012). (2012) reported that quality scores for “Tah Tasai” Chinese cabbage (Brassica rapa subsp. (2012) showed that red cabbage, cilantro, garnet amaranth, and green daikon radish microgreens had the highest concentrations of ascorbic acid, carotenoids, phylloquinone, and tocopherols, respectively, with the levels of these bioactive components being significantly higher in microgreens compared to data base values for mature vegetable counterparts. Basil microgreens are chock full of nutrients, including vitamins A, B6, C, E, and K, as well as minerals like calcium, copper, magnesium, phosphorus, iron, and zinc. vetstud / Originally Posted in Antioxidants Sprouting Up Answer: USDA researchers recently published a study assessing the nutrition content of 25 commercially available microgreens, seedlings of vegetables and herbs that have gained popularity in upscale markets and restaurants. Dong, Iniguez, Ahmer, and Triplett (2003) inoculated the roots of 1–2‐day old alfalfa seedlings with a low inoculum level of 102 cfu per plant Salmonella Typhimurium and found that the pathogen colonized the interiors of 6–9‐day old seedlings in high numbers. When microgreens were stored at 10 °C instead of 4 °C, shelf life was reduced from 14 to 7 days for arugula and red cabbage microgreens and from 21 to 14 days for radish microgreens (Berba & Uchanski, 2012). Seeds of some varieties are soaked overnight enhance germination. LED light systems provide distinct operational advantages and are environmentally friendlier than GDLs (Agarwal & Gupta, 2016; Morrow, 2008). Despite widely varying practices, microgreen production generally has several key differences from sprout production. Kale microgreens contain over forty times the nutrients achieved from adult kale. The seeds of alfalfa, mung bean, radish, arugula, buckwheat, sunflower, and many other vegetables produce sprouts, or microgreens, when grown in flats or simply sprouted in jars. (2015) found that glucosinolates were the main compounds in broccoli microgreens that were enhanced by 10 mM calcium chloride preharvest treatment. Since microgreens are very delicate and more susceptible to physical damage, it can be assumed that preventing physical injury during harvesting and subsequent handling, distribution, and marketing is critical. I’m going to answer that to the best of my ability. Similarly, the effect of cool nighttime temperatures on plant growth, nutrition, and food safety of microgreens has not been assessed. Hydroponic pads and soil‐less substrates tend to be favored for this practice for ease of transport and perception of cleanliness in a kitchen environment (Renna, Di Gioia, Leoni, Mininni, & Santamaria, 2017). Microgreens freeze rapidly if held below 0 °C, causing substantial physical damage. Thus, a combination of adequate cold chain and suitable modified atmosphere packaging (MAP) are essential to reduce respiration rates, prevent moisture loss, reduce environmental contamination, and inhibit growth of spoilage and pathogenic microorganisms (Berba & Uchanski, 2012; Zagory & Kader, 1988). The rapidly growing microgreen industry faces many challenges. Refrigerated temperatures also slow respiration rate, which is a key factor in delaying senescence. It is certainly clear that postharvest light treatments can enhance the formation bioactive components, but this has not been systematically studied to optimize nutrient content in a full range of potential microgreens. MAP must be optimized for individual commodities since use of inappropriate modified atmospheres can induce physiological disorders, prevent wound healing, hasten senescence and increase susceptibility to pathogen growth and decay (Wagner et al., 2009). Microgreens are further developed than sprouts and have a slightly higher fiber content. Try microgreens in your next salad in place of spinach! Relative humidity (RH) is another factor influencing quality and safety of fresh‐cut produce. Mustard Microgreens . Here's what you should know about the types and benefits of microgreens, plus recipe ideas and growing tips. Pinto et al. Increases in SPAD readings were observed for Egyptian spinach microgreens growing under yellow, green, blue, white light, and natural light. However, specific data on the optimal prevention and intervention steps needed for the various microgreens are generally not available. Although it’s not as popular as lettuce micros, it is definitely worth a try. The chlorine treatment may have altered the natural microflora on the radish microgreens allowing chlorine‐resistant microbes to thrive that had previously been checked by competing microbes. The light treatment preserved higher levels of chlorophyll a, chlorophyll b, total chlorophyll, AP, TP, and AA than did darkness. Kyriacou et al. Hydroponic systems have been evaluated as a means of tailoring the optimal nutrients for the cultivar and functional benefits for intended consumers. Red Cabbage Microgreens. Washing greens prior to packaging reduces initial bacterial load, but creates a humid environment which promotes microbial growth and necessitates removal of excess water to discourage such growth. Our baby kale is a nutritional powerhouse, super tender and surprisingly sweet. Zhan, Hu, Li, and Pang (2012) measured nutritional quality associated with pigments, antioxidant power (AP), total phenols (TP), reduced ascorbic acid (AA), and fresh weight loss of fresh‐cut broccoli exposed to continuous 24 µmol m−2 s−1 light or held in darkness (control) during storage at 7 °C temperature during 10 days shelf life. Bower and Mitcham (2001) reported that 1‐MCP delayed senescence including leaf yellowing, abscission, and decay in several vegetables including cultivars of Brassica oleracea. Wang, Luo, and Nou (2015) examined the survival and proliferation of seed‐borne L. monocytogenes and other members of the seeds microbiota on microgreen plants grown in soil substitute and hydroponic production systems. If you've always thought of microgreens—those delicate miniature leaves often used as a garnish on soups, sandwiches and salads—as nothing more than cute edible decor, well, join the club. Microgreens are young vegetable greens that are approximately 1–3 inches (2.5–7.5 cm) tall. When samples were stored at 1 °C, the radishes retained nearly 100% over 2‐week storage period, but when stored at 5 °C retention dropped to approximately 60%, and at 10 °C plummeted to 25%. Sun et al. Most seed contamination resulted in colonization of the surrounding water. Working off-campus? Visit CalorieKing … One major limitation to the growth of the microgreen industry is the rapid quality deterioration that occurs soon after harvest, which keeps prices high and restricts commerce to local sales. NASA scientists have begun to explore the challenges and benefits of growing microgreens in space. Microgreens are edible seedlings including vegetables and herbs, which have been used, primarily in the restaurant industry, to embellish cuisine since 1996. 250 grams. … of Agriculture, Beltsville, MD, 20705 U.S.A. Dept. Washed radish (Xiao et al., 2014b) and buckwheat microgreens (Kou et al., 2013) deteriorated much faster than unwashed microgreens, due in part to damage incurred during washing and dewatering, but primarily due to the excess moisture in packages of washed microgreens. Most of the inoculated E. coli cells survived on the microgreen surfaces, showing only a slight decline from initial inoculum levels after 7 days of storage. Nutrition | Science | Trends However, low‐light conditions caused plant leaves to undergo an increase in the relative number of light‐harvesting complexes and in the stacking of thylakoid membranes to form grana, changes which optimize light utilization (Walters, 2005).
