Problems solved by technology

Some of these methods use high-pressure fluid nanomill equipment, which require conditions such as high temperature, high pressure, and ultra-high frequency ultrasonic waves. The amino acid chelated calcium prepared is a single amino acid chelated calcium, and the reaction conditions are relatively high, and the single amino acid chelated calcium is not suitable. in the long-term continuous supplementation; other methods are to use some leftovers or waste products as raw materials to prepare amino acid chelated calcium. The amino acid chelated calcium prepared by these methods is generally not high in purity and is mostly used in the field of feed. There is a big gap, and the whole production process is relatively cumbersome, and chemical products such as acid and alkali are used, and a large amount of industrial sewage that is difficult to treat will be generated during the production process.

Abstract

The invention discloses a high-efficiency and clean production process of compound amino acid chelated calcium. By enzymatically hydrolyzing the protein, adding inorganic calcium in the middle and late stages of enzymolysis for chelation, followed by inactivation of enzymes, solid-liquid separation, ultrafiltration, concentration, and drying to obtain compound amino acid chelated calcium. At the same time, the macromolecular protein, inorganic calcium and purified water separated in the intermediate process are reused as part of the raw materials for the next batch of production. The invention combines the enzyme reaction and the chelation reaction, and performs the chelation reaction in the middle and later stages of the enzyme reaction, shortens the production cycle, has relatively mild reaction conditions, and does not need complex equipment such as high temperature and high pressure. In the whole production process, no organic solvents, inorganic acids and bases and other unnecessary substances are added, and the products produced are safe and reliable. In this process, the raw materials are fully recycled, the product yield is improved, the discharge of sewage and solid waste is minimized, and clean production is realized.

Description

technical field [0001] The invention relates to a high-efficiency and clean production process for preparing compound amino acid chelated calcium by adopting a biological enzyme method. Background technique [0002] Calcium is an essential element for human life activities and the most abundant mineral element in the human body. It is of great significance to maintain the normal physiological functions of the human body. At present, there are three types of calcium supplement products: inorganic calcium, organic acid calcium and organic calcium. Among them, inorganic calcium (such as calcium carbonate) and organic acid calcium (such as calcium citrate) have low absorption rate and are easily polluted by anions. , have side effects on the stomach, deposits in the kidneys to form stones and other disadvantages. [0003] The representative of the new type of organic calcium is amino acid chelated calcium, which has the advantages of direct absorption by the body without digest...
