Embodiment Construction

[0027] A method for preparing lysine chelated calcium using bay scallop shells as a calcium source, comprising the steps of:

[0028] A. Shell treatment: After the shells are routinely cleaned, they are dried, crushed, and then carbonized and ashed;

[0029] B. Ash treatment: Treat the shell ash with a slightly excess HCl solution to obtain CaCl 2 solution;

[0030] C. Mixed reaction: CaCl 2 The solution is heated and stirred with lysine for chelation;

[0031] D. Centrifugation: Centrifuge the reaction solution and keep the supernatant;

[0032] E. Evaporation and concentration: Slowly heat the reaction solution to evaporate and concentrate;

[0033] F, alcohol precipitation: purify lysine chelated calcium with absolute ethanol;

[0034] G. Drying: collect the gel precipitate, wash repeatedly with absolute ethanol, and dry at a constant temperature of 60-80°C to obtain the product.

[0035] Wherein, the specific conditions of the step A are: the bay scallop shells are r...

Abstract

The invention discloses a method for preparing a calcium lysine chelate with the shell of Argopecten irradias as a calcium source. The method comprises the following steps: treatment of the shell of Argopecten irradias: successively subjecting the shell of Argopecten irradias to conventional cleaning, air drying, crushing, charing and ashing; ash content treatment: treating the ash content of the shell with a slightly excess HCl solution so as to obtain a CaCl2 solution; mixing reaction: heating and mixing the CaCl2 solution and lysine under stirring so as to realize chelating; centrifugation: carrying out centrifugation and retaining a supernatant; evaporative concentration: subjecting a reaction solution to slow heating for evaporative concentration; alcohol precipitation: purifying a calcium lysine chelate obtained in the previous step by using absolute ethyl alcohol; and drying: collecting a gel precipitate, repeatedly washing the gel precipitate with absolute ethyl alcohol and then carrying out drying at a constant temperature of 60 to 80 DEG C so as to obtain the calcium lysine chelate. The preparation method for the calcium lysine chelate in the invention uses processing waste of Argopecten irradias, i.e., the shell, and the essential amino acid lysine as raw materials and prepares the calcium lysine chelate through water-phase synthesis; and the method is low in cost, good in chelation yield and suitable for large-scale batch production.

Description

technical field [0001] The invention relates to the field of food biotechnology, in particular to a method for preparing lysine chelated calcium using bay scallop shells as a calcium source. Background technique [0002] Calcium is an important element in the composition of the human body. It is the most abundant in the human body and can account for 1.5%-2.0% of the body weight. 99% of the calcium in the normal adult body exists in the bones and teeth, and the remaining 1% exists in the extracellular fluid, cell membrane and soft tissue. The position of calcium in the human body is very important. On the one hand, it gives bone strength in the form of bone salt, and becomes the main support of the human body to bear the weight of the body; on the other hand, calcium plays a role in various physiological functions and metabolic processes in the form of ions. Such as blood coagulation, muscle contraction, neuromuscular stress, improvement of microcirculation and phagocytosis...
