First: What kind of burdock is of good quality?
Second: Are there any pictures for reference?
The first question: What is the quality of burdock?
I learned the export standard of burdock through the official website of Tianyi International Group a few years ago, and now I share it with you. According to the length, it can be divided into grade A, grade B and grade C. The length of grade A burdock is more than 70 cm, grade B burdock is more than 40 cm and grade C burdock is more than 20 cm. According to the diameter of burdock, burdock has 2L, L, M, 2m, S and 2S grades. For example, those with a diameter of 3.0-3.5 cm are 2L, those with a diameter of 2.5-3.0 cm are l, those with a diameter of 2.2-2.5 cm are m, those with a diameter of 1.8.2-2.2 cm are 2M, and those with a diameter of1.5-1. Take burdock with a length of more than 70cm and a diameter of1.8.2-2.2cm as an example. The export grade is A2M. If the length is more than 40cm, it is B2M.
The price of fresh burdock is generally the most expensive in grade A, followed by grade B and grade C is the cheapest. The same is true of quality.
Generally, the quality requirements of grade A burdock are higher, and there can be no hollowness, bifurcation, saccharification and black circles. Grey circle, bug eye, scar, big capillary root.
Generally, the quality requirements of B-grade burdock are not too high. Because most of B-grade burdock is thick, hollowness, bifurcation and black circle are common, which is the main raw material of most low-quality large-scale burdock tea.
The second question: Are there any pictures for reference?
If you need a lot of pictures of burdock, you can send me a private message and I will send you an email.
If you just want to know the general idea, I will send you a picture for your reference. This is Tianli burdock chips. The reason why I sent this picture is because the color of a good burdock is milky white, without hollowness and black circles.
Please enjoy the picture taken when the burdock root was just pulled out.
If you need other information about burdock, I can continue to provide it. I hope I can help you. Thank you.
