The caterpillar medicinal mushroom Cordyceps militaris contains many bioactive components, such as adenosine, cordycepin, and polysaccharides. In this study, C. militaris was exposed to 0, 3, 6, or 9 pulses of light irradiation to estimate changes in vitamin D2, bioactive compounds, nonvolatile taste components, and antioxidant properties. In addition, we compared the components and properties of C. militaris mycelia and solid waste medium that had been treated with pulsed light (PL) irradiation. Overall, PL irradiation of C. militaris increased the vitamin D2 content and increased the total amino acid levels 9-48%; the antioxidant properties of the mycelia treated with 0 pulses and of the solid waste medium treated with 3 pulses all exhibited lower half-maximal effective concentrations. Therefore, PL irradiation affected the amounts of bioactive compounds, but the irradiated samples still contained intense umami taste and a sufficient amount of antioxidant components.
蚕蛹虫草含有许多生物活性成分，如腺苷、虫草素和多糖。在本研究中，将蚕蛹虫草暴露于0、3、6或9次脉冲光照射下，以评估维生素D2、生物活性化合物、非挥发性风味成分和抗氧化特性的变化。此外，我们比较了经脉冲光（PL）照射处理的蚕蛹虫草菌丝体和固体废料培养基的成分及特性。总体而言，对蚕蛹虫草进行PL照射可提高维生素D2含量，并使总氨基酸水平提高9%至48%；经0次脉冲处理的菌丝体和经3次脉冲处理的固体废料培养基的抗氧化特性均表现出较低的半数最大效应浓度。因此，PL照射影响了生物活性化合物的含量，但照射后的样品仍具有浓郁的鲜味和充足的抗氧化成分。
