Problems solved by technology

Obviously, no matter the product obtained by chemical method or enzyme treatment, it is no longer a compound of the original natural structure in the pearl; and it also destroys or loses some valuable nutrients

Embodiment 1

[0033] Preparation of nanoscale chelated shell nacre products

[0034] Preparation method: select fresh pearl shells, abalone shells, oyster shells and other shells with nacre, remove old broken shells, thoroughly decontaminate and remove impurities with clean water or dilute alkaline water; polish with stainless steel wire brush, remove Remove the horny layer and shuttle column layer on the shell, rinse it with tap water and then rinse it twice with pure water; soak the polished and rinsed shell nacre layer in hydrogen peroxide aqueous solution for disinfection and sterilization, and then rinse it once with pure water , to dry or to dry;

[0035] Crush the nacre of the shell and roughly crush it to about 400 mesh with a pulverizer; prepare a 15% suspension with pure water for the 400 mesh powder, adjust the pH to PH7.5, inject it into a high-pressure homogenizer, and press 100MPa to make the suspension The solids in the powder are ultrafinely pulverized to less than or equal...

[0039] Preparation of nano-scale chelated shell nacre products

[0040] Preparation method: The difference is that it is soaked in dilute alkaline water, stirred intermittently, then rinsed with tap water to remove dirt and impurities, and polished with a grinding wheel to completely remove the horny layer and shuttle column layer; the polished shell nacre layer is first rinsed with tap water , and then rinsed with pure water 1-2 times, then soaked in hydrogen peroxide solution for disinfection and sterilization, stirred properly, about 1-2 hours, then took out and dried; coarsely crushed 400 mesh powder, and the above coarse powder Carry out supersonic airflow pulverization, use the impact force of the airflow in the pulverizer and the powder to collide with each other, so as to achieve the purpose of pulverization many times, and use the sub-rotor to classify the powder in the classification room, so that the coarse powder can be returned to continue to be pulverized, Collec...

Embodiment 3

[0042] Preparation of nano-scale chelated shell nacre products

[0043] The preparation method is the same as in Example 1, except that the 400-mesh powder is made into a 20% suspension with purified water, and the pH value is adjusted to 7.4, and then injected into a high-pressure homogenizer with a pressure of 100Mpa; the suspension is injected into a high-pressure liquid Nano mill, the pressure is controlled at 120MPa, the injection speed of the suspension is 200 liters per hour, the nanometerization and chelation are completed in the physical and chemical chamber, and the centrifugal drying is obtained.

Abstract

The present invention discloses a nano-grade chelate-type complete shell pearl layer product and its production process. Said production process includes the following steps: using shell as raw material, selecting material, removing impurity, grinding to remove cuticle and prismatic layer, cleaning, disinfecting, drying, coarse-pulverizing, ultrafine pulverizing, filtering, preparing nano particles, dewatering, drying, stabilization treatment and packaging, its grain size is less than 80 nm. Said shell pearl layer product contains nutrient components of natural pearl, such as amino acids, protein, calcium and other several trace elements, so that it has extensive application field.

Description

technical field [0001] The invention relates to a shell nacre product for medical treatment, health care and beauty, in particular to a nanoscale chelated shell nacre product with good water solubility, easy absorption and high bioavailability, its preparation method and application. Background technique [0002] my country is the earliest country in the world to collect and utilize pearls. In the "Shangshu Yugong" in 2200 BC, it is recorded that the pearls obtained by Dayu's flood control should be used as tributes. There are also records about pearls in the "Book of Books" of the Spring and Autumn Period, which draws a "full picture of Tiangong's creation of pearls". During the Three Kingdoms period, Zhuge Liang used pearls to make "Xingjun powder" to treat diseases. As for the artificial breeding of pearls, Pang Yuanying of the Song Dynasty had detailed records in his "Wenchang Miscellaneous Records". In the past 30 years, my country's pearl breeding industry has develo...
