Some users in the use of Chinese medicine crusher to crush Chinese medicinal materials, found that the Chinese medicinal materials after grinding discoloration, it will feel that the quality of Chinese medicinal materials or the problem of Chinese medicine crusher equipment. In fact, this is the normal phenomenon and change after the crushing of Chinese medicinal materials, then why such a situation?
The change in color is because the Chinese herbal medicine after being crushed by the Chinese medicine crusher, into the state of powder, the area becomes larger, the reflectivity and reflection Angle of the light to the particles will change, resulting in changes in color, the general naked eye looks dark gray, such as pearl powder clearly should be white pearl powder is gray with the naked eye.
Temperature will also cause discoloration, the composition of medicinal materials is relatively stable under normal temperature (15-23℃) conditions, but with the rise and fall of temperature, the medicinal materials themselves will produce physical, chemical and biological changes. The rise in temperature will accelerate the movement of the molecules of the substance, make the medicine itself heat up, and the water evaporates, which may cause the color of the medicine to change.
In addition, humidity will also have a certain impact. The area of contact between crushed Chinese medicinal materials and the air will increase. If the subsequent storage environment humidity is large, and the powder will be damp, it will also cause color changes. Therefore, the crushed Chinese herbal medicine powder should also pay attention to the subsequent storage work to avoid moisture and affect the efficacy.
Therefore, the reasons for the change of color of Chinese medicinal materials after being crushed by Chinese medicine crusher are various, including but not limited to the above reasons, and some color changes are normal phenomena, not the quality of equipment or medicinal materials. However, in some small details, such as paying more attention to the storage environment, this color change can be greatly reduced.
