Abstract

The invention discloses a preparation method of active fine powder containing oyster calcium. Oyster shells are washed, ground, calcined, crushed and dissolved, CO2 is collected, filtration and heating concentration are performed, a coarse product is collected, redissolution, recrystallization and drying are performed, and the active fine powder containing oyster calcium is prepared, wherein the content of calcium bicarbonate is higher than 95.5%, and rich natural active substances such as microelements, minerals and the like are contained. The calcium bicarbonate prepared with the method is good in quality and high in content, the product is good in stability and contains rich natural active substances, compared with a traditional method, the method is low in energy consumption in the production process, saves time and is a production technology which adopts the advanced preparation process, is efficient, environment-friendly, sanitary and has significant economic benefit.

Description

technical field [0001] The invention belongs to the technical field of production, processing and extraction of marine organisms, and in particular relates to a preparation method of active fine powder of oyster calcium. Background technique [0002] Calcium bicarbonate is an inorganic acid salt, soluble in water, chemical formula Ca(HCO 3 ) 2 , relative molecular mass 162.06. Calcium (Ca) is one of the important components of the human body and generally exists in the form of calcium ions. Calcium has a large content in the human body, most of which exist in bones and teeth, and a small amount exists in blood and tissues. Due to metabolism, a certain amount of calcium needs to be supplemented from food every day. Calcium ions are indispensable ions for various physiological activities of the body. It maintains the biological potential on both sides of the cell membrane, maintains normal nerve conduction function, maintains normal muscle contraction and relaxation funct...
