1, visual inspection method. True Dendrobium is usually light yellow in appearance, smooth in surface, complete in pedicel, compact in texture and clear in texture, while false Dendrobium is rough in color, gray or light brown, with damaged or uneven surface. In addition, Dendrobium with good quality generally looks well-proportioned, full of particles and dark in color.

2. Odor recognition method. The real Dendrobium has a strong smell, while the fake Dendrobium or inferior Dendrobium has a relatively inconspicuous smell, which may have an odor. Authentic Dendrobium with good quality has no peculiar smell, but also has a faint grass fragrance.

3. Damage identification method. The damage degree of true Dendrobium is very low, because Dendrobium is brittle, while false Dendrobium is soft and easy to be damaged.

4. Use fire identification method. The real Dendrobium will have a smoky smell similar to the burning of rock sugar, and the texture is hard, while the fake Dendrobium is rough and has no obvious aroma when burning.

5, soaking water identification method. After Dendrobium is soaked in water, true Dendrobium will soften quickly, while false Dendrobium will take a long time to soften.

6. Chewing discrimination method. If you put a Dendrobium maple bucket in your mouth to chew, if you can taste the slightly sweet taste of Dendrobium and feel sticky in your mouth, then Dendrobium will melt in your mouth, so the quality of this Dendrobium is generally better.
