Preparation method of nano pearl proteins

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...
