摘要：
Intense pulsed light irradiation is used in food decontamination and in production of mushrooms with high level of ergocalciferol. Lentinula edodes (Berk.) Pegler, shiitake, was freeze-dried and milled into powder and irradiated with 20, 40 and 60 pulses of pulsed light at a distance of 6 cm and the irradiation energy were 26.2, 52.4 and 78.5 kJ/m(2), respectively. The contents of ergocalciferol and total phenols increased dose-dependently whereas ergothioneine contents were not affected. The most effective conversion of ergosterol to ergocalciferol was 20-pulse treatment. Further, irradiated and nonirradiated shiitake showed a moderate inhibition in decreasing nitric oxide and interleukin-6 productions but no effect on tumor necrosis factor-alpha production. In addition, pulse light treatment could improve antioxidant activities. Overall, using pulsed light irradiation could produce irradiated shiitake as an excellent vitamin D-2 supplement with similar ergothioneine and higher total phenols contents as well as similar anti-inflammatory and better antioxidant activities.
