Zinc deficiency is a global health issue, and agronomic biofortification is a promising strategy to enhance the bioaccessibility of Zn in edible crops. Microgreens, with their short growth cycle, high nutrient-density, and low antinutrient content, are ideal candidates for Zn-enrichment via fertigation. While controlled environments allow light modulation to optimize yield and quality, limited information exists on how Zn-enrichment and light together influence metabolite biosynthesis. This study evaluated metabolic responses in radish microgreens grown under varying Zn (0–15 mg/L) and light intensity (100–400 μmol/m2/s) levels using targeted metabolomics. High light intensity increased flavonoid and phenolic-acid levels, suggesting enhanced antioxidant responses, while reducing amino acids and glucosinolates, indicating a resource shift toward stress mitigation. Zn enrichment modulated phenylpropanoid, nitrogen, and energy metabolism, increasing specific flavonoids, phenolic acids, essential amino acids, and ATP. These findings provide insights into optimizing Zn- and light inputs to produce biofortified, nutrient-rich microgreens with improved functional-food potential.

番茄和胡萝卜是食物中类胡萝卜素的主要来源。类胡萝卜素有助于降低多种慢性疾病的风险，包括心血管疾病和癌症。类胡萝卜素的健康影响不仅取决于其在食物中的浓度，还取决于其生物可利用率（Bioaccessibility）——即这些物质在经过人体消化后到底有多少能真正被肠胃吸收。生物可利用率会根据烹饪方式不同而产生显著差异。热处理通过破坏细胞结构和促进微胶粒形成提高类胡萝卜素的生物可利用率，但过高的温度或过长的时间可能导致其降解和异构化。根据发表在《Food Chemistry》期刊上的一项研究，研究人员对比了空气炸锅、烤箱和微波炉烹饪番茄和胡萝卜的生物可利用率。结果显示：胡萝卜经烤箱烹饪后，其总类胡萝卜素的生物可利用率最高可达原来的 9 倍；对于西红柿，无论采用空气炸锅（190 ℃ 10 分钟）还是传统烤箱（180 ℃ 20 分钟）烹饪，均可获得最高的生物利用率；对胡萝卜来说，微波加热是效率最高的烹饪方式，可将电力消耗降低 96%；对于西红柿来说，使用空气炸锅不仅能获得最高的生物可利用率，还能减少 80% 的耗能。
