How Do LED Grow Lights Influence Fruit and Vegetable Flavor? From Sugar-Acid Ratio to Aroma Compound Regulation

In modern protected horticulture, LED grow lights are no longer used solely for boosting yields—they are increasingly being leveraged to fine-tune the flavor and nutritional quality of fruits and vegetables. The perception of "deliciousness" in produce is determined by a combination of factors, including the sugar-to-acid ratio, accumulation of aroma compounds, and pigment biosynthesis. Accurate management of light spectrum, photoperiod, and intensity plays a central role in influencing these flavor-related attributes.
