Objective: To study the feasibility of using stereoscopy in identification on Edible Bird's Nest (EBN).
Method: Characteristics of white EBN pieces, red EBN, white fungus pieces and EBN painted with colloid were observed under stereoscopy.
Results: EBN pieces could be distinguished from white fungus pieces under stereoscope. The former is semitransparent and has more fine cracks; the latter is opaque and without fine cracks. EBN painted with colloid can be distinguished under stereoscopy too. The characteristics include: (1) the surface lines were not clear; (2) feathers were plastered on the surface.
Conclusions: Stereoscopy can be used in identification of EBN, especially in general investigation of commercials.
