Abstract This study evaluated, at a meso-scale, the antifungal effect of 405 nm LED illumination against Botrytis cinerea and Rhizopus stolonifer on tomatoes, as well as its effect of on the physicochemical properties. Tomatoes were surface-inoculated with B. cinerea and R. stolonifer, and illuminated with 87 W/m2 for twelve days. Subsequently, the antifungal effect, defined as the difference in mold populations on the control and illuminated samples, was observed to be 1.9 log CFU/g for B. cinerea and 3.2 log CFU/g for R. stolonifer. In terms of physicochemical effects, beginning from day 9, the total phenolic content, TEAC and vitamin C content of illuminated samples was significantly higher (P > 0.05) by 24.6 %, 28.2 % and 16.5 %, respectively, compared to control, but a greater reduction in mass and lycopene content was also observed. Overall, these results suggest the potential of 405 nm LEDs for controlling mold growth on tomatoes during transportation and storage, retaining their physicochemical quality.

中尺度系统中 405 nm 发光二极管对番茄的抗真菌作用及其对理化性质的影响

摘要 本研究在中尺度上评估了 405 nm LED 照明对番茄灰葡萄孢和根茎根霉的抗真菌作用及其对理化性质的影响。西红柿表面接种 B. cinerea 和 R. stolonifer,并以 87 W/m2 光照 12 天。随后,抗真菌作用(定义为对照样品和光照样品上霉菌种群的差异)被观察到,对于 B. cinerea 而言为 1.9 log CFU/g,对于 R. stolonifer 而言为 3.2 log CFU/g。在理化效应方面,从第 9 天开始,光照样品的总酚含量、TEAC 和维生素 C 含量分别显着高于对照组(P > 0.05)24.6 %、28.2 % 和 16.5 %,但还观察到质量和番茄红素含量的下降幅度更大。
