1. Look, when you identify the authenticity of the iron maple bucket, you can look at it first. For the processed Dendrobium, there will be a layer of fine hair, which is formed by drying the epidermal fibers of its stem. Secondly, we should have fine modeling, fine workmanship, uniform size and full particles. Tell me what color it is first. Because of the high sugar content, the real maple barrel will be dark and yellow-green. If waxed, it will reflect light. Dendrobium rubbed with newspaper ash can be touched by hand, leaving gray marks on fingers. 2, smell second, you can also smell with your nose. Put one around your nose and smell it. Real maple barrels will give off a faint scent of grass, not other odors. This is because when processing Dendrobium, it is baked slowly with charcoal fire, kneaded and rolled into a spring shape to become the final shape. Therefore, if you smell a strange smell, it is probably not a tin maple bucket. 3. Pull, introduce a method to identify Dendrobium, that is, pull by hand. Pull the maple bucket from the middle position to both sides. Generally, if the sugar content is high, it will be interrupted by a gentle pull. If it can be pulled for a long time without signs of breaking, it can be judged as a fake Dendrobium candidum, which is an important method to identify its authenticity. Step 4 chew. What does it taste like? This is another way I want to tell you. Chew a maple bucket in your mouth. It will feel dry and hard at first, but it is like this at first. You need to chew hard. Slowly, I will feel that it is changing, becoming more and more sticky, not as hard as when I first put it in my mouth, and more comfortable. Finally, almost the whole Dendrobium melted in his mouth. This is the magic of the iron maple bucket, "it looks like grass and chews sugar." 5, the price has said so much, and the price of Dendrobium can also judge its authenticity. Many phoenix beans in the market are called Dendrobium candidum, but in fact most of them are sold with purple skin or Dendrobium nobile as iron sheets. As we all know, the real Dendrobium officinale is a medicinal material with a price of one point, and its price is also directly proportional to the market at that time. If it is low, it can't be Dendrobium candidum. Note: With the passage of time, the color of the maple bucket will become darker, but it will never turn black. Dendrobium has a hard texture and will take a long time to fry.
