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 an efficient cleaning production process of compound amino acid chelated calcium. Through proteolysis, inorganic calcium is added in the middle and late stage of enzymatic hydrolysis for chelation; and then enzyme inactivation, solid-liquid separation, ultrafiltration, concentration and drying are carried out to obtain the compound amino acid chelated calcium. At the same time, high molecular protein, inorganic calcium and purified water isolated in an intermediate process are reused as part of the raw materials for the production of a next batch. The invention combines enzyme reaction with chelating reaction, and the chelating reaction is carried out in the middle to late stage of the enzyme reaction to shorten the production cycle. The production process has mild reaction conditions, and does not require high temperature and high pressure complex equipment; and the whole process does not use any excessive material such as organic solvent and inorganic acid and alkali, and the produced product is safe and reliable. The process fully recycles raw materials, improves product yield, reduces discharge of sewage and solid waste by the maximum level, and achieves clean production.

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...
