Water soluble nacre powder chelation technology

Abstract

The invention discloses a water soluble nacre powder chelation technology. The technology comprises the steps of 1) liquid-solid phase reaction: putting coarse nacre powder obtained through pretreatment in an open container, adding a gluconic acid solution till no CO2 is produced, stopping the reaction and performing filtering and drying to obtain organic acid nacre powder; 2) chelating amino acids: mixing the organic acid nacre powder with the amino acid solution to perform chelating reaction for 1h to 2h, performing spray drying under 180MPa to 210MPa to obtain the water soluble nacre powder. According to the technology, the nacre powder is obtained with pearl shells serving as the raw materials through an amino acid chelating technology, and accordingly, the poor smashing effect caused by direct physical smashing of traditional technologies is prevented, damage of the traditional inorganic acid hydrolysis method to natural beneficial microelements and active ingredients in the pearl shells can be prevented. The technological method is simple, the cost is low, the produced nacre powder particles are small, nutritional ingredients are rich, the nacre powder can be digested easily by bodies, and good market application prospects are provided.

Description

technical field [0001] The invention belongs to the field of preparation of water-soluble nacre powder, in particular to a chelating process of water-soluble nacre powder. Background technique [0002] Nacre powder is a good health food and cosmetics. Its particle fineness has a great relationship with the absorption and utilization rate of its functional ingredients. The traditional preparation of nacre powder adopts two methods: physical pulverization or inorganic acid hydrolysis, but The nacre powder obtained by physical pulverization has problems such as high cost, too large particle size, and poor absorption by the human body and skin, resulting in a large waste of active ingredients in the original application of nacre powder. However, the inorganic acid hydrolysis method, as a This typical chemical method not only causes the loss of a large amount of natural beneficial trace elements and organic active ingredients in nacre powder, but also has a complicated process, w...

[0002] Nacre powder is a good health food and cosmetics. Its particle fineness has a great relationship with the absorption and utilization rate of its functional ingredients. The traditional preparation of nacre powder adopts two methods: physical pulverization or inorganic acid hydrolysis, but The nacre powder obtained by physical pulverization has problems such as high cost, too large particle size, and poor absorption by the human body and skin, resulting in a large waste of active ingredients in the original application of nacre powder. However, the inorganic acid hydrolysis method, as a This typical chemical method not only causes the loss of a large amount of natural beneficial trace elements and organic active ingredients in nacre powder, but also has a complicated process, which is not suitable for promotion, and waste liquid will be generated during the process, which will pollute the environment, but these processes either High cost, or loss of natural beneficial trace elements and organic active ingredients
