Abstract

The invention discloses a preparation method of calcium amino acid chelate and belongs to the technical field of food processing. According to the method, a hydrochloric acid solution is used for soaking egg shells, the hydrochloric acid solution reacts with the egg shells, an inorganic calcium source is generated, then a certain amount of egg white is added and evenly mixed, enzymolysis is conducted through protein hydrolytic enzyme, amino acid is generated, then zinc acetate is added, assisted by microwaves and electricity, calcium amino acid chelate crude products are generated, filtering, refining and drying are conducted, and the calcium amino acid chelate is obtained. It is proved that by means of the method, the complex percentage of amino acid is increased by 5-10%, product purity reaches over 98%, the operation process is simplified, industrialized mass production of the calcium amino acid chelate can be achieved, and the yield is raised.

Description

technical field [0001] The invention discloses a preparation method of amino acid chelated calcium, which belongs to the technical field of food processing. Background technique [0002] Calcium is one of the most important elements in the human body. The function of almost every system of the human body is related to calcium. The harm of calcium deficiency to the human body has become an eye-catching worldwide problem. Especially the impact on infants, the elderly, pregnant women and patients with certain diseases is more serious. It has become a consensus that scientific calcium supplementation is beneficial to health. Normal people's daily physiological demand for calcium is 350-550 mg, but according to Chinese eating habits, the daily calcium intake from food is only 170-220 mg. [0003] According to incomplete statistics, there are more than 200 kinds of calcium supplement preparations in the domestic market at present, but in terms of their calcium sources, they are b...
