What Is Pearl Powder?

Freshwater pearls are different from seawater pearls (in the case of southern pearls), so their structures are different. Freshwater pearls are nucleus-free, and all ingredients are made of pearly substance. Therefore, if pearl powder is made from freshwater pearls, there is no other substance mixed. Seawater pearls have a nucleus. The nucleus is generally ground from the shell of the hoofed clam. The pearly substance only covers the surface and is 0.1 to 0.3 mm thick. However, if seawater pearls are to be processed into 100% pearl powder, the core must be removed first, which is costly and not easy to process.

   Water-soluble pearl powder is generally treated with acid (mostly lactic acid) or enzymes, so that water-insoluble CaCO3 becomes soluble calcium lactate, and soluble salts such as calcium, strontium, and magnesium salts are formed class. In addition to calcium supplementation, it can also produce iron lactate, ferric ammonium lactate, potassium lactate, sodium lactate, bismuth lactate,

   Look at the type:

   To process seawater pearls into pure pearl powder, the core must be removed first, the cost is high, and it is not easy to process. Even if the purity is processed, the purity of freshwater pearl powder is higher than that of seawater pearl powder.

   Look at the packaging:

   Good pearl powder is mostly stored in bottles and sealed, which can reduce the contact area of pearl powder with air and human body, which is convenient for storage. Bagging is not conducive to the preservation of pearl powder, and it is also not conducive to consumers' access to it. Low-cost packaging is mostly a hard-hit area.

   Look at the amount:

   Supply of high-quality pearl powder is in short supply, and it is often out of stock, with an average weight of about 30g per bottle. The poor and fake pearl powders are mostly used at low prices and large portions. When you see a gram above 100g (especially in bags), you must choose carefully.

   Look at the fineness:

   The finer pearl powder is better, but the unit of fineness of pearl powder is "micron" instead of the so-called "mesh" and "million mesh". There is no "nano" level of pearl powder, so the promotion can be seen Come on.

   Look at the price:

   Will pearl powder be taken orally?

   There is no stone formation when taking genuine high-quality pearl powder. After a long epidemiological study, scientists have found that calcium deficiency is the main cause of stones. Because the main component of kidney stones is calcium oxalate, the content of oxalic acid in the body is too high, it is easy to combine with calcium in the body to form water-insoluble calcium oxalate, which may form stones. Pearl powder contains a lot of calcium. Intake of pearl powder, the calcium ions released by it can be combined with oxalic acid in the intestine to form insoluble calcium oxalate, which is eliminated from the body, thereby preventing it

   The main origin of pearl powder is China. The main reason is that China's pearl production accounts for more than 95% of the global total output, and it has rich pearl resources.

   Pearl powder is processed from pearls. For the processing method of pearl powder, the "Chinese Pharmacopoeia" and "Chinese Medicine Processing Standard" both use traditional water fly method to prepare pearl powder. Due to the increasing market demand for pearl powder, the traditional technology has low production efficiency, long production cycles, large loss rates, and difficult to control microbial pollution. To this end, many new pearl powder processing technologies have appeared in various places. First, several processing methods of pearl powder are introduced as follows:

   Traditional crushing method

   Wash the pearls, wrap them in gauze, add tofu (1: 1) and cook with water for 2 hours. Take out the tofu, wash it, dry it, grind it, and fly it with cold water. Take it out, put it in a paper-lined bamboo basket, and dry or dry it.

   Mechanical crushing

   After elutriating the pearls, scrub them in alkaline water to remove grease, rinse with alkaline water to remove the alkali, drain or gauze dry the water, spread them evenly in a pan, and then place them in a constant temperature oven at 120-160 ° C. . When the surface of the pearl is yellow and there is a cracking sound, cut off the power. When it is cooled to 60-70 ° C, take it out quickly, crush it with a pulverizer while it is hot, and then heat it in an oven, and grind it through a sieve.

   Ball milling

   After the pearls were crushed into granules, the pearls were immersed in alkaline water and foamed. Wash away oil and attachments, rinse with water to neutrality, and drain. Place in a ball mill cylinder, add an appropriate amount of distilled water, and ball mill. Take it out, lay it evenly in a square dish, and place it in an electric heating incubator at 140-160 ° C to dry. Take it out and let it cool, and sieve in a closed shaker.

   Jet mill

   Take the pearl powder that has been pulverized into nearly 200 meshes, place it in a jet mill, and use a classification collection device to collect the powder that does not meet the requirements until it reaches the specified fineness range.

   Vibration kneading and crushing method

   Take pearls that have been soaked and rinsed in alkaline water to neutrality, and dried and sterilized, and crushed in a vibration kneading machine. According to the requirements of fineness, different crushing media are pre-selected, and the principle of vibration grinding is used to make them crush. Required fineness.

   Special processing method

   "Pearls, rounds, and springs" may be the highest evaluation of women's skin. The "bead" here refers to pearls. This shows the relationship between pearl powder and beauty.
