Preparation method of fully active component nano pearl powder

Abstract

The invention discloses a preparation method of fully active component nano pearl powder. The key point and bottleneck of the pearl powder preparation are full preservation of active components in pearls, and the technical problem is not well solved and has been neglected for a long time. The preparation method comprises the following steps: choosing high quality pearls, cleaning, drying in air, and grinding, wherein pearls are grinded into pearl powder with a particle size of 2-50 [mu]m in one step through a combined method of drying in the air by cool wind, low-speed grinding and pulverizing, and winnowing; and the temperatures of all materials during the whole processing process are below 45 DEG C. The provided fully active component nano pearl powder is suitable for preparations of medicines, healthcare products, foods, and cosmetics. The preparation method is capable of preserving the characteristic natural components and bio-activity of pearl, and improving the absorption efficiency of pearl for human body, and prominently increases the medicinal value, healthcare function, and beautifying and skin moistening effect of the pearl powder.

Description

technical field [0001] The invention relates to a method for preparing pearl powder with all active ingredients, and belongs to the technical field of marine biological pearl processing. Background technique [0002] Pearls are calcium carbonate-containing mineral (aragonite) beads produced in the body of pearl oysters and nacre molluscs due to endocrine action, and are composed of a large number of tiny aragonite crystals. In the long history, pearls have been recognized as precious treasures of traditional Chinese medicine, which have the functions of calming the nerves, calming convulsions, improving eyesight, detoxifying and promoting muscle growth. Calcium and other aspects have a unique role. [0003] Pearl powder is mild in nature. After being absorbed by the human body, it participates in the metabolism of the body, nourishing the inside and outside, so as to achieve the overall conditioning and maintenance of the whole body skin. It can promote the synthesis of ne...

Problems solved by technology

The composition of the pearl powder processed by chemical method and biological (enzyme) method has changed significantly, while the pearl powder in the physical method has a process of heating and heating, so that the biologically active ingredients contained in it, such as protein, small molecule active polypeptide, vitamin B group substances are damaged to varying degrees, so that the natural components of the original pearl are partially or completely changed, and its functional biological activity is lost, and some are even completely lost.

Ruan Huajun proposed the preparation method of all-natural nano-pearl powder (CN100388981C) in 2005, and believed that it could guarantee the all-naturalness and integrity of the pearl components. Commonly used high-speed shearing and crushing methods will cause high temperatures, and the drying temperature should be controlled at 60-70°C, which will cause the biologically active ingredients contained in pearls such as protein denaturation, small molecule active polypeptides to be inactivated, and vitamin B group substances to be affected to varying degrees. Destruction, which eventually leads to impairment of the functional activity of pearl powder products

Among the pearl ingredients, the calcium content accounts for the vast majority, and the active ingredients only account for a small amount. However, it is the active ingredients in pearls that play the role of treatment, health care and beauty. If the active ingredients are lost during processing, or the active ingredients are made Inactivation, the remaining pearls only contain calcium, therefore, fully retaining the active ingredients in the processing process is the key to the pearl processing process, and this is just the bottleneck in the current pearl processing technology, and it has not been well-received for a long time. Technical problems that are easy to solve but ignored
