L-aspartic acid chelated calcium and preparation method thereof

Abstract

The invention relates to L-aspartic acid chelated calcium and a preparation method thereof. The preparation method comprises the following steps: adding calcium hydroxide and L-aspartic acid into water; then homogenizing and dispersing; regulating the pH (Potential of Hydrogen) value of a solution to be 7.3 to 7.5; then de-coloring and filtering to obtain a dissolved solution with the solid content granularity which is less than 30mu m; enabling the dissolved solution to react under pre-set temperature and pre-set pressure; then carrying out concentration to obtain a concentrated solution; depressurizing and cooling the concentrated solution to obtain an L-aspartic acid chelated calcium crystal; adding the L-aspartic acid chelated calcium crystal into water; then carrying out homogenization and dispersion and filtering treatment in sequence to obtain amino acid chelate clear liquid; then carrying out spray-drying treatment on the amino acid chelate clear liquid to obtain the L-aspartic acid chelated calcium. The invention provides a method for efficiently and rapidly producing amino acid chelate in a large scale; the reaction time can be shortened and the yield is improved; the purity of the prepared L-aspartic acid chelated calcium is high, and the production cost can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of calcium preparations, in particular to L-aspartic acid chelated calcium and a preparation method thereof. Background technique [0002] Calcium is the most abundant metal element in the human body. Under normal circumstances, the total calcium content in the adult body is about 120 grams, of which about 99% are distributed in bones and teeth, and the remaining 1% exists in cells in the form of free or combined ions. In external fluids, blood and soft tissues. Calcium is not only the main component of human bones and teeth, but also plays a role in the normal fluctuation of the heart, blood coagulation, conduction of normal excitability of muscles and nerves, maintenance of suitable induction, permeability of cell membranes, and various enzymes. The activity and other physiological functions play an important role. Calcium deficiency can cause various diseases, especially for infants, pregnant women and ...

Problems solved by technology

So far, its preparation methods mainly include chemical synthesis and electrolysis-semipermeable membrane methods, but the main problems of these methods include: slow reaction, long time, low yield, incomplete reaction, and removal of the remaining reactions that do not participate in the synthesis It is more difficult to produce, therefore, it is more difficult to produce on a large scale
