How to identify the authenticity of pearl powder

Because pearl powder is becoming more and more popular in the market, some unscrupulous vendors will add some additives into the pearl powder. Therefore, people often buy a bag of worthless pearl powder because they are buying it for the first time and do not understand the ingredients contained in it and how to identify it. In fact, pearl powder is divided into several grades. We can learn about it when buying pearl powder.

There are several important characteristics of real pearl powder. Please keep them in mind and be careful to distinguish them:

1. Smell. Real pearl powder has a light fishy smell, which is the natural smell of pearls, not the kind that makes people sick; generally speaking, the smell of ultrafine pearl powder is stronger than that of ordinary pearl powder; and the smell of nano pearl powder is stronger than that of ultrafine pearl powder.

2. Taste. Real pearl powder tastes slightly salty, nano pearl powder is a bit like sugar-free milk, and tastes mellow and comfortable, while shell powder is mostly a bit astringent. Inferior pearl powder has sour, astringent, spicy or other strange smells, or has no smell at all. If there is a burnt or mushy smell when taking the medicine, and the powder is yellow in color, it may be the residual powder from pearl drilling. The high-speed rotation of the black steel needle causes the powder to turn yellow due to heat. Long-term use of this pearl powder may lead to heavy metal accumulation and poisoning.

3. Color. The color of real pearl powder is off-white, that is, close to white. The color of pearl powder with different processes will be slightly different. Some are slightly gray, and some are slightly yellow. But it is definitely not the kind of pale white color, nor the burnt yellow color, it should be very soft.

4. Price. Basically, no real pearl powder is sold in bags of 100 grams, 200 grams or even 400 grams. A bag costs a few yuan or dozens of yuan. Real pearl powder is not that cheap. The production cost of high-quality pearl powder: high-quality medicinal pearls is about 100 yuan/kg, plus packaging, equipment depreciation, management fees, logistics costs, etc., so high-quality medicinal pearl powder must be more than 100 yuan. Of course, it does not mean that pearl powder that costs more than 100 yuan is high-quality pearl powder.

5. Liquidity. Fake pearl powder is made from coarsely crushed shells. It is extremely coarse and feels heavy in the hand. You can see it sparkle when you hold it under the light, and it has excellent fluidity (fine enough pearl powder will turn into lumps when you pinch it, while coarse enough pearl powder will spread out like sand). Identification method: Most of the pearl powders sold in the market are packaged in bags. When purchasing, try to pinch the bag. If the powder quickly moves away (flows) away from the part where you apply pressure, then: even if it is pearl powder, it is extremely coarse pearl powder. If the area you press does not fall apart easily, or even does not fall apart at all, but instead gathers into a tight mass, it means that the pearl powder is already very fine.

6. Relevant certifications. Manufacturers of pharmaceutical pearl powder with national drug approval numbers must pass GMP certification (Good Manufacture Practice), otherwise the safety of the product cannot be guaranteed. Manufacturers of high-quality pearl powder will be very careful about every detail of the product. For example, there will be no errors in the Chinese and English text and even punctuation on the packaging. The printing quality and packaging quality requirements are very strict. The color will not be dark, the overprint will not be inaccurate, and the seal will not be crooked.
