The magical beauty and health benefits of pearl powder are derived from the various natural nutrients contained in the pearl powder. The pearl powder has physical properties that are insoluble in water. Therefore, if the nutrients are to be absorbed by the body, the pearl powder must be processed enough. fine. Therefore, the improvement of the processing technology of pearl powder in the past generations all surrounds this. At present, the quality of pearl powder on the market is uneven. The following methods can help you identify: 1, smell Pearls are animal proteins that smell lightly. Of course, some fake pearl powder made from clam shells also have a slight astringency, but there is no fake powder. 2, specific gravity (into the water reaction) The proportion of pearl powder is 1.75-1.86, so there will be a diffusion effect and sink in the water. High-quality pearl powder has a small surface area and a small surface area. The water has a small buoyancy, so it sinks into the water. Inferior pearl powder is too thick and has a large surface area. It diffuses first after entering the water, and then gradually sinks. The fake pearl powder is generally oyster powder, and even talc powder is incorporated, the specific gravity is obviously lighter, so after entering the water, it often floats on the surface in a pile, does not spread, and sinks a small amount. 3, taste Take a small amount of pearl powder and taste it with your tongue. The pure pearl powder has no peculiar smell, and the taste is mellow, and the Chinese medicine ceremony records: pearl, the taste is light and salty. The aftertaste has a hint of astringent astringency (or a similar seafood flavor) and no acid, sputum, scent or other odor. The high-quality pearl powder is imported, and the thicker pearl powder has a grainy grain. Summary: All the above methods need to be purchased first and then tested and judged. In fact, the price, product packaging, instructions, etc. can basically judge the authenticity of the product before purchase. First of all, let's take a look at the production cost of pearl powder: the purchase price of raw materials for general medicinal pearls is about 100 yuan/kg, plus packaging, equipment depreciation, management fees, logistics costs, etc. How can the price of a dozen yuan be possible? Buy one or two hundred grams of real pearl powder? Secondly, pearl powder, as an animal protein, is easily contaminated and breeds bacteria. Therefore, regular manufacturers generally produce pearl powder by the standard of pharmaceuticals, strictly distinguishing between internal and external products. Oral is generally a capsule or a separate small package of 0.3 grams, and the external use will generally not exceed 50 grams of packaging.
