Microgreens have recently gained importance being a dense source of bioactive compounds that offer several health benefits. This review explores the innovation in non-thermal techniques and their application in seed germination and microgreen cultivation, with a major focus on increasing the growth rate and improving nutritional and bioactive composition. Non-thermal techniques like ultrasonication, ultraviolet light, cold plasma, and magnetic field treatment are discussed for their ability to enhance the rate of germination and improve the seed quality by influencing plant growth rate and minimizing microbial proliferation. These methods align with sustainable food processing, offering energy efficiency and minimal environmental impact. As microgreens are nutrient-dense foods rich in vitamins, minerals, and bioactive compounds, offer significant health benefits such as antidiabetic, anti-obesity, anti-inflammatory, and anti-cholinergic making them an ideal candidate for functional food applications.
