以香菇为原料，研究了喷雾冷冻干燥法制备挥发性细粉的方法。采用顶空固相微萃取-气相色谱-质谱联用技术对水溶性芳香族化合物进行分析。采用扫描电镜和激光粒度分析表征了sfd衍生颗粒的物理结构和尺寸分布。从香菇sfd前后提取液中鉴定出11种关键挥发性化合物。结果表明，用SFD法提取的粉末中芳香挥发物的回收率为30.9% ~ 82.9%。扫描电镜分析表明，芳香粉末颗粒呈球形，表面多孔，平均直径为19.3 μ m。
In this study, a method to produce a fine volatile powder extracted from shiitake mushrooms using spray freeze-drying (SFD) was investigated. The analysis of the water-soluble aromatic compounds was carried out by headspace solid-phase micro-extraction coupled with gas chromatography-mass spectrometry. Scanning electron microscopy and laser particle size analysis were applied to characterise the physical structure and size distribution of the SFD-derived particles. Eleven key volatile compounds were identified in the extracts of shiitake mushrooms pre- and post-SFD. Recoveries of aromatic volatiles ranging from 30.9% to 82.9% were observed in the overall flavour profile results from the powder obtained with SFD. Scanning electron microscopy analysis demonstrated that the particles of the aromatic powder were spherical in nature, having highly porous surfaces and mean diameters of 19.3 mu m.
