Microgreens in sustainable food systems: A critical review of nutritional quality, production technologies, and security implications

Introduction

Microgreens are young vegetable, herb, or grain seedlings typically harvested 7-21 days after germination, when the cotyledons are fully developed and the first true leaves may begin to emerge. Despite their small size, microgreens are nutrient-dense, often containing higher concentrations of vitamins, minerals, and antioxidants than their mature counterparts (Kyriacou et al., 2016; Xiao et al., 2021) [14,34] . Their vibrant colors, distinctive flavors, and abundance of health-promoting phytochemicals have contributed to their increasing popularity among culinary professionals and health-conscious consumers. Microgreens can be cultivated using soil-based systems, hydroponics, or biodegradable substrates, making them well suited for urban agriculture, vertical farming, and indoor production systems (Di Gioia et al., 2020) [7] . Their short growth cycle, low input requirements, and high economic return per unit area further enhance their potential as a sustainable and profitable crop. This production potential is particularly significant in regions with limited agricultural land (Poudel et al., 2022) [25] . The rising popularity of microgreens is further driven by a growing global shift toward sustainable food systems and functional foods. Research has demonstrated that microgreens of species such as broccoli, red cabbage, and radish are especially rich in bioactive compounds, including glucosinolates, polyphenols, and carotenoids (Zhang et al., 2023) [38] . These phytochemicals are associated with several potential health benefits, such as anti-inflammatory, anticancer, and cardioprotective effects, highlighting the nutritional and therapeutic relevance of microgreens in modern diets.

Historical Development of Microgreens

Microgreens, now recognized as a class of functional foods, have evolved from niche culinary garnishes into mainstream health-oriented produce. Their journey reflects growing consumer awareness of nutrition, sustainability, and innovative food production systems. The concept of microgreens originated in the United States during the early 1980s, particularly in upscale Californian restaurants, where chefs experimented with young vegetable seedlings for their intense flavors, vibrant colors, and delicate textures (Kyriacou et al., 2016) [14] . Initially, only a limited range of crops such as arugula, basil, beet, and cilantro were cultivated; however, increasing demand soon expanded the diversity of species grown as microgreens. By the 1990s, microgreens gained widespread recognition in gourmet cuisine due to their aesthetic appeal and concentrated flavours (Xiao et al., 2013) [29] . Their popularity gradually extended beyond fine dining as consumers and researchers alike began to appreciate their nutritional richness, leading to increased scientific interest and advancements in cultivation practices.

During the 2010s, research on microgreens intensified, focusing on their nutritional composition, cultivation techniques, and health-promoting bioactive compounds. This body of evidence supported their classification as superfoods, with studies demonstrating that microgreens often contain higher concentrations of vitamins, minerals, and antioxidants than their mature counterparts (Mir et al., 2023; Brazaitytė et al., 2021) [20,2] .

Recent technological advancements, including LED lighting systems, vertical farming, and controlled environment agriculture, have further accelerated microgreens production and accessibility. These technologies enable year-round cultivation with minimal land and water requirements, making microgreens particularly suitable for urban agriculture and indoor farming systems (Pinto et al., 2021) [24] . Today, microgreens are not merely a culinary trend but represent a sustainable, nutrient-rich food source that contributes to food security, dietary diversity, and human health promotion What are microgreens? Young, edible vegetable, herb, or grain seedlings known as microgreens are picked during the cotyledon stage, usually 7-21 days following germination. They are often eaten uncooked and are bigger than sprouts but smaller than baby greens. Microgreens' strong flavour, vivid colour, and high nutritional content make them popular garnishes or additions to salads, smoothies, and sandwiches.

These tender greens are rich in vitamins (such as C, E, and K), minerals, antioxidants, and various phytochemicals, often present in higher concentrations than those found in mature plants, making microgreens a valuable component of a healthy diet mature plants. Commonly cultivated microgreens include broccoli, radish, beet, kale, arugula, and basil (Kyriacou et al., 2016; Xiao et al., 2021) [14,34] . Microgreens can be grown in soilbased or soilless media, such as hydroponic systems or cocopeat, and have gained considerable popularity in urban farming and health food markets due to their rapid growth cycle, minimal space requirements, and significant nutritional and health benefits.

Immature Harvesting Growth Stages of Microgreens

Microgreens are harvested at an early, immature stage of development, typically 7-21 days after germination, depending on the crop species and prevailing environmental conditions. The optimal harvest stage occurs after the full expansion of the cotyledon leaves and just before or at the emergence of the first true leaves (Kyriacou et al., 2016) [14] . Harvesting at this stage ensures that the plants remain tender, visually vibrant, and rich in nutrients and bioactive phytochemicals, maximizing both their nutritional quality and consumer appeal.

Stages of Microgreen Growth

The growth and development of microgreens can be broadly divided into the following stages: expanded, and this stage is considered the optimal harvest period for most microgreens due to maximum tenderness and nutritional quality (Xiao et al., 2021) [34] .

The first true leaves begin to appear. Harvesting at this stage may slightly reduce tenderness but can enhance flavor intensity and complexity, depending on the species.

• Broccoli microgreens are particularly recognized for their strong anticancer potential, as they contain significantly higher levels of sulforaphane compared to mature broccoli, enhancing their chemoprotective effects (Sun et al., 2022) [20] . • Radish microgreens, rich in glucoraphanin, help neutralize carcinogens and may prevent the initiation and progression of cancerous cells (Mir et al., 2023) [30] .

Growing Process of Microgreens 1. Seed Selection and Variety Choice

Selection of high-quality seeds is critical for successful microgreen production. Crops such as radish, broccoli, sunflower, pea shoots, and mustard are commonly used due to their rapid germination and high nutritional value. Other varieties, including arugula, cilantro, and basil, are preferred for their distinct flavors and added health benefits (Xiao et al., 2012) [35] . The cultivation of microgreens involves a series of carefully managed steps, from seed selection to post-harvest handling, to ensure the production of nutrient-dense, high-quality young plants. Microgreens are typically grown within a short production cycle of 7-21 days, depending on the crop species and environmental conditions.

Seed Soaking

Certain seeds, particularly sunflower and pea shoots, benefit from pre-soaking to soften the seed coat and enhance germination. Soaking typically lasts 4-12 hours, depending on the seed type, and improves germination uniformity and early seedling vigor (Mir et al., 2023) [20] .

Selection of Growing Medium

Microgreens can be cultivated in soil-based or soilless media, including coconut coir, hydroponic mats, and other inert substrates. Coconut coir is widely used due to its lightweight nature, high water-holding capacity, and good aeration, which promote healthy root growth (Kyriacou et al., 2016). Hydroponic systems are increasingly popular for their water efficiency, though they require precise nutrient management (Pinto et al., 2021) [24] .

Sowing of Seeds

Seeds are sown densely and uniformly over the growing medium to maximize yield in limited space. They are lightly pressed into the substrate or left uncovered, depending on seed size. Proper density is essential to avoid overcrowding, which can restrict airflow and promote disease development (Mir et al., 2023) [20] .

Germination and Environmental Conditions

During germination, microgreens require controlled environmental conditions. Optimal temperatures range from 18-22 °C, along with high humidity, often achieved by covering trays with lids or humidity domes (Xiao et al., 2012) [35] . Light is not essential during germination; however, once seedlings emerge, exposure to light becomes critical for photosynthesis.

Lighting

Following germination, microgreens require adequate light for healthy growth and pigment development. LED grow lights are commonly used in indoor systems as they provide an optimal light spectrum. A photoperiod of 12-16 hours per day is generally recommended (Kyriacou et al., 2016) [14] . Insufficient light may reduce growth and flavor, while excessive light can cause heat stress.

Watering and Nutrient Management

The growing medium should be kept consistently moist but not waterlogged. Gentle misting or light irrigation is preferred to prevent disturbance of seedlings. In some systems, a dilute nutrient solution is applied to support growth. Hydroponic systems rely entirely on nutrient-enriched water to supply essential macro-and micronutrients (Pinto et al., 2021; Mir et al., 2023) [24,20] .

Harvesting

Microgreens are ready for harvest within 7-21 days, when plants reach a height of approximately 2-3 inches and the first true leaves begin to appear. Harvesting is performed by cutting the stems just above the growing medium using sharp scissors or a knife, ensuring minimal damage to surrounding plants (Xiao et al., 2012) [35] .

Post-Harvest Handling

After harvest, microgreens should be gently washed to remove substrate residues and excess moisture. They are then drained, packed, and stored under refrigerated conditions to maintain freshness, nutritional quality, and shelf life. Proper post-harvest handling is essential to reduce microbial contamination and preserve product quality.

After washing, microgreens are carefully dried to remove excess surface moisture and prevent spoilage. The harvested produce should be stored in a cool and dry environment, preferably under refrigerated conditions, to maintain freshness, nutritional quality, and shelf life. Proper packaging, such as ventilated or moistureabsorbing containers, is essential to prevent moisture accumulation, which can otherwise lead to mold growth and decay (Pinto et al., 2021) [24] .

Difference between Sprouts and Microgreens

Sprouts and microgreens are both young, edible forms of plants; however, they differ markedly in their cultivation methods, growth stages, nutritional composition, safety aspects, and culinary uses. [35] .

Broccoli (Brassica oleracea var. italica)

Broccoli microgreens are especially valued for their high content of sulforaphane, a powerful antioxidant derived from glucoraphanin. These compounds are associated with anticancer, anti-inflammatory, and detoxifying effects, often present at higher levels than in mature broccoli (Xiao et al., 2012; Sun et al., 2022) [35,30] .

Kale (Brassica oleracea var. acephala)

Contains beta-carotene, calcium, iron, and polyphenols. Known for its anti-inflammatory and antioxidant properties (Pinto et al., 2021) [24] .

growth, harvest, and storage, these pathogens can contaminate the produce, leading to foodborne illnesses. Leafy greens, including microgreens, have been reported among the top contributors to outbreaks (Manning et al., 2021) [18] .
