Recently, composting cultivation method is widely used in oyster mushroom production. In this study, we focused on the effects of composting processes on nutritional qualities and antioxidant activity of Pleurotus floridanus mushroom fruiting bodies. Three treatments of different composting time (2, 4, and 5 days) were performed with an atmospheric sterilization treatment as the control. The results showed that the pH value, total carbon content, and total nitrogen content of substrate were critical parameters which would significantly affect mushroom qualities and bioactivities. Fruiting bodies of the control demonstrated significantly higher crude protein content, total amino acid content, and essential amino acid content than that of composting treatments. Moreover, fruiting bodies of treatment D4 and D5 manifested significantly higher crude polysaccharide contents. Crude polysaccharide of treatment D4 represented the highest scavenging ability toward both radical 3-ethylbenzthiazoline-6-sulfonic acid (ABTS· ) and Hydroxyl radical (OH·). It suggests that composting processes is suitable for oyster mushroom cultivation based on nutritional and antioxidant qualities of fruiting bodies.
最近，堆肥栽培方法在蚝蘑生产中得到了广泛应用。本研究聚焦于堆肥过程对佛罗里达侧耳蘑菇子实体营养品质和抗氧化活性的影响。采用三种不同的堆肥时间（2、4 和 5 天）进行处理，并以大气灭菌处理作为对照。结果表明，基质的 pH 值、总碳含量和总氮含量是显著影响蘑菇品质和生物活性的关键参数。与堆肥处理相比，对照组的子实体具有更高的粗蛋白含量、总氨基酸含量和必需氨基酸含量。此外，D4 和 D5 处理的子实体表现出更高的粗多糖含量。D4 处理的粗多糖对 3-乙基苯并噻唑啉-6-磺酸（ABTS·）和羟自由基（OH·）均具有最高的清除能力。这表明，基于子实体的营养品质和抗氧化活性，堆肥过程适合蚝蘑的栽培。
