Embodiment 1

[0017] Take 10 kg of pearl grains and crush them with a crusher, then crush them with an ultrafine pulverizer to 300 mesh particles, and then pulverize them with a jet mill to obtain 7.83 kg of pearl powder with an average particle size of 1-4 μm.

[0018] Soak the 7.83kg pearl powder with 100kg of 15% edible acetic acid solution for 72 hours, the pearl powder is fully dissolved, filter with a filter cloth to obtain a filter residue, and repeatedly wash the filter residue with purified water to between Ph5-8. Obtained filter residue 0.310kg (water content), 10g was taken and dried for testing, and 4.723g of dry matter was obtained, and the solid content of the filter residue was calculated to be 47.23%.

[0019] Add purified water to the filter residue to 10kg, add 1g Tween 20, 3g sodium hexametaphosphate, stir evenly and then grind it with KLZr-3 horizontal nano-sand mill at a speed of 2000r / min, with a grinding ball of 0.2mm, and grind for 6 hours. After grinding for 1 hour,...

Embodiment 2

[0021] Take 15 kg of pearl grains and crush them with a crusher, then crush them to 300 mesh particles with an ultrafine pulverizer, and then pulverize them with a jet mill to get 12.6 kg of pearl powder with an average particle size of 1-4 μm.

[0022] Soak the 12.6kg pearl powder with 150kg of 15% edible acetic acid solution for 72 hours, the pearl powder is fully dissolved, filter with filter cloth to obtain filter residue, wash the filter residue repeatedly with purified water to between Ph5-8. Obtained filter residue 0.453kg (containing water), 10g was taken and dried for testing, and 4.693g of dry matter was obtained, and the solid content of the filter residue was calculated to be 46.93%.

[0023] Add purified water to the filter residue to 15kg, add 1.5g Tween 20, 4.5g sodium hexametaphosphate, stir evenly and then grind with KLZr-3 horizontal nano-sand mill, rotating speed 2000r / min, grinding ball 0.2mm, grind for 9h. After 2 hours of grinding, the grinding solution w...

Embodiment 3

[0025] Take 20kg of pearl grains and crush them with a crusher, then pulverize them to 300 mesh particles with an ultrafine pulverizer, and then pulverize them with an airflow pulverizer to obtain 17.4kg of pearl powder with an average particle size of 1-4 μm.

[0026] Soak the 17.4kg pearl powder with 200kg of 15% edible acetic acid solution for 72 hours, the pearl powder is fully dissolved, filter with a filter cloth to obtain a filter residue, and repeatedly wash the filter residue with purified water to between Ph5-8. Obtain 0.680kg of filter residue (containing water), take 10g and dry it for testing, and obtain 4.771g of dry matter, and calculate the solid content of the filter residue to be 47.771%.

[0027] Add purified water to the filter residue to 20kg, add 2g Tween 20, 6g sodium hexametaphosphate, stir evenly and then grind it with KLZr-3 horizontal nano-sand mill at a speed of 2000r / min, with a grinding ball of 0.2mm, and grind for 11 hours. After grinding for 1 h...

Abstract

The invention relates to a preparation method of nano pearl proteins. The preparation method comprises the following steps: crushing pearls into pearl micropowder with the average grain size of 1-4 microns, carrying out acidolysis, filtering, washing the filter residues by purified water to obtain coarse pearl proteins, adding a dispersant into the coarse pearl proteins to grind, and carrying out ultrasonic concussion in the period; and concentrating the grinded liquid by a membrane, and heating, sterilizing and storing to obtain the nano pearl proteins. The preparation method provided by the invention is simple in process, organically combines the nano grinding technology with the emulsifying and dispersing technology, and further enhances the emulsifying and dispersing effect by means of ultrasonic waves, so that the pearl protein particles effectively reach nanoscale. The pure nature and integrity of the pearl protein component can be maintained by pure physical processing, and the nano pearl proteins are uniform in particle and are easily assimilated by human body and further by skins, so that the nano pearl proteins are suitable for being used as an additive of medicines, nutrients and skin care products.

Description

technical field [0001] The invention relates to the technical field of pearl powder processing for medical use or cosmetics, in particular to a preparation method of nano pearl protein. Background technique [0002] Pearl is a kind of precious Chinese herbal medicine, which has the effects of calming the nerves, improving eyesight, detoxification and beauty care. Modern scientific analysis shows that pearls are rich in pearl protein, amino acids, more than 20 kinds of trace elements, porphyrin and rich in calcium. Among them, pearl protein is a good beauty product. It is used externally to cover the skin, and has the functions of moisturizing, nourishing the skin, and whitening the skin. [0003] At present, the extraction of pearl protein mainly adopts the acid dissolution method. After the pearl is crushed, it is dissolved with edible acid, filtered, and the filter residue is washed with purified water to obtain pearl protein. The pearl protein extracted by the acid diss...
