Problems solved by technology

So now the actual situation is: Many factories only use strong alkaline substances such as NaOH to remove the outer cuticle and then crush it. The pearl layer powder obtained by these low-cost methods is easy to be destroyed, and its medicinal value will be reduced. big discount

Abstract

The invention provides a method for preparing abalone shell pearl layer powder. The method comprises the following steps of: soaking abalone shells into acid solution to obtain abalone shell pearl layers, performing grinding, acid dissolution and alkali soaking, and dissolving in acid solution to obtain the abalone shell pearl layer powder. Compared with the prior process for preparing the abalone shell pearl layer powder, the method of the invention has the advantages that: the obtained abalone shell pearl layer powder keeps all components of the abalone shell pearl layers, and the soluble powder keeps most components of a biological sample. Compared with a water-soluble pearl powder production method, the method has simple preparation process, and can greatly reduce the production cost and relieve environmental pollution and energy consumption.

Description

technical field [0001] The invention relates to a preparation method of abalone shell pearl layer powder. Background technique [0002] Nacre, also known as hypostracum, is the innermost structure of the shell of molluscs (such as mussels). It is usually shiny and has strong refractive reflection. [0003] Nacre powder is ground into powder from the inner layer of mollusc shells. Nacre powder and pearl powder are homologous and contain the same ingredients as pearls, mainly calcium, sugars, various amino acids and A small amount of trace elements, the keratin contained in it has a variety of amino acid components that cannot be produced by the human body. Pearl layer powder has multiple functions such as applying the face to remove freckles, treating skin allergies, removing acne, and moisturizing the skin. [0004] The cost of nacre powder itself is very low. In order to obtain nacre, the cuticle on the outer surface of the shell and the prismatic layer in the middle mu...
