摘　　要：芽苗菜正逐渐成为一类具有广阔发展前景和巨大市场潜力的新兴健康植物源食品。发光二极管(Light Emitting Diode,LED)作为一种高效、节能、环保的固态光源,已被广泛应用于芽苗菜的栽培和品质调控。基于芽苗菜的营养价值和LED光照技术,综述LED光照对芽苗菜色泽(叶绿素、β-胡萝卜素)、营养物质(可溶性糖、可溶性蛋白质)、抗氧化物质(酚类物质、维生素C)及抗氧化活性的调控作用,并解析其调控机制。认为,与同种成熟蔬菜相比,芽苗菜含有更多的β-胡萝卜素、叶绿素、酚类物质、维生素C等生物活性物质,具有更高的营养价值及更强的抗氧化活性。LED能够提供与植物体内光感受器和光合色素(如叶绿素、类胡萝卜素)吸收谱相匹配的最优光波长,对植物生长发育、光合作用、次生代谢产物合成等具有重要促进作用,可实现植物生产效率的最大化。红光、蓝光、红蓝复合光和绿光均能促进芽苗菜中营养物质和抗氧化物质的合成,并提高其抗氧化活性。未来研究将集中在LED光质配比、LED光照协同其他因素、LED光照对采后芽苗菜贮藏保鲜的调控作用及机制等方面,为芽苗菜生产、加工、贮藏保鲜全产业链发展提供理论依据和技术参考。Microgreens are emerging as a novel category of healthy plant-derived food sources with vast development prospects and enormous market potential.Light emitting diode(LED),as an efficient,energy-saving,and environmentally friendly solid-state illuminant,has been extensively applied in regulating the growth and quality of microgreens.Based on the nutritional characteristics of microgreens and LED lighting technology,the regulatory effects of LED lighting on color(chlorophyll,β-carotene),nutrients(soluble sugars,soluble proteins),antioxidants(phenolic substances,vitamin C)and antioxidant activities of sprouts were reviewed,and the possible regulatory mechanisms were analyzed.Compared with the same mature vegetables,microgreens contained more bioactive substances such asβ-carotene,chlorophyll,phenolic substances and vitamin C,and had higher nutritional value and stronger antioxidant activity.LED light source provided the optimal wavelength matching the absorption spectrum of photoreceptors and photosynthetic pigments(such as chlorophyll and carotenoids)in the plant body,which played a crucial role in optimizing plant growth and development,photosynthesis,and secondary metabolites synthesis,thereby maximizing plant production efficiency.Red-light,blue-light,red-blue combined light,and green-light promoted the synthesis of nutrients and antioxidants,and increased antioxidant activity in microgreens.Future research will focus on the light-quality ratio,LED light coordination with other factors,and the regulatory effect and mechanisms of LED light on the storage and preservation of microgreens,so as to provide theoretical foundation and technical reference for the production,processing,storage,and preservation of microgreens entire industrial chain.
