Abstract
The invention discloses a preparation method of amino acid chelated copper. The product belongs to the field of a feed additive. The preparation method comprises the following steps: by taking amino acid, copper sulfate, water, 10% of sodium hydroxide aqueous solution, and dilute ethanol as raw materials, taking a chemical reaction kettle, a centrifugal separator and a dryer as equipments to produce the amino acid chelated copper in batches. The method is simple in technology, mild in reaction condition, free of sewage and exhaust emission, excellent in product quality; the activity of enzyme in an animal body can be enhanced after the amino acid chelated copper is added to the feed and eaten by animals; the utilization rate of protein, fat and vitamin is improved. Thus, the growth performance of the animal is improved. The using method of the amino acid chelated copper is to dope a chicken feed, a pig feed and a fish feed according to the ratio of 0.05% of weight of the feed.
Description
Technical field
The invention belongs to feed additive field, relate in particular to a kind of method of suitability for industrialized production feed addictive copper amino acid chelate.
Background technology
Copper is one of requisite nutrient in growth of animal process, initial copper is that form with copper sulphate is introduced directly into feed as trace element, although copper sulphate is water-soluble fine, but in animal alimentary canal easily with feed in common phytate anion, oxalic acid anion through the biochemical reaction form in animal body, form the mantoquita that corresponding solubility is very little, difficult by intestinal absorption.Development along with feed industry, trace mineral supplement copper amino acid chelate is developed gradually, its feature be stablize, efficiently, toxicity is little, in enteron aisle, be easy to digest and assimilate, be conducive to growth of animal, can prevent and treat the copper deficiency disease of animal, can obviously improve the immunity of organisms of animal, and useful for utilizing of nutrition composition in feed, also have the effect of high-protein agent concurrently.So-called chelate is exactly the complex compound with certain structure type, be that ligand can be with two or more coordination atoms and same central ion complexing, Chelates of Amino Acids And Trace Elements forms coordinate bond with the nitrogen-atoms in divalent metal and amino amino, it is generally acknowledged that amino acid forms with trophism trace element the chelate that ligancy is 4 conventionally, its chela number of rings is 2, be that amino acid and micro-mol ratio are 2:1, the formation of chela ring causes chelating ion to dissociate than non-chelate ion more difficult fractionation in the aqueous solution.Copper amino acid chelate is because of after its metal ion is combined by coordinate bond with amino acid molecular, make its intramolecular charge be tending towards neutral, formed more stable chemical constitution, not only good stability, good fluidity, antagonism are few, after entering in animal body, in digestion process, influenced factor is little, is convenient to abundant absorption and the utilization of body to copper ion.The present invention mainly provides a kind of production method of the copper amino acid chelate being formed by chelating by amino acid and copper, copper amino acid chelate adds in feed, can make the good palatability of feed, absorptivity is high, easily transhipment, can strengthen the activity of animal body endoenzyme, improve the utilization rate of protein, fat and vitamin, thereby improve the growth performance of animal.
Summary of the invention
The problem that the present invention mainly solves is to provide that a kind of to take amino acid and copper sulphate be raw material, take chemical reaction kettle, centrifugal separator, dryer is the method for equipment batch production copper amino acid chelate, the method technique is simple, reaction condition is gentle, without sewage toxic emission, good quality of product, copper amino acid chelate adds in feed by after animal edible, can strengthen the activity of animal body endoenzyme, improve the utilization rate of protein, fat and vitamin, thereby improve the growth performance of animal.Producing the raw material that this product uses has: amino acid/11 6%-18%, copper sulphate 5%-7%, water 77%, 10% sodium hydrate aqueous solution is appropriate, Diluted Alcohol is appropriate.
The present invention can be achieved through the following technical solutions:
Produce a method for copper amino acid chelate in batches, it is characterized in that being formed by following steps:
(1) in reactor, first add the water of formula ratio, then add successively amino acid, copper sulphate, stirring blending is even, at normal temperatures, the sodium hydrate aqueous solution control pH value of use 10% between 7.1-7.3, stops after stirring reaction 0.6-0.8 hour stirring all the time, and chelatropic reaction finishes.
(2) reactant is sent into centrifugal separator separation, remove the solid obtaining after moisture and be the copper sulphate of copper amino acid chelate and a small amount of not chelating, now in 1:1, obtain ratio and add Diluted Alcohol, utilize copper amino acid chelate to be insoluble to Diluted Alcohol, and copper sulphate is dissolved in the principle of Diluted Alcohol, after stirring elimination Diluted Alcohol reclaim stand-by, the remaining copper amino acid chelate that is, copper amino acid chelate is sent into drying machine sealing and dry, after then oven dry thing being pulverized, be packaged to be finished product.
(3) using method of copper amino acid chelate is: in the ratio of feed weight 0.05%, mix chicken feed, pig feed, fish meal.
Amino acid described in above-mentioned steps (1) comprises methionine, lysine, L-Trp;
The baking temperature of the drying machine described in above-mentioned steps (2) is 90 ℃-100 ℃, and drying time is 10 hours.
The present invention compared with prior art has the following advantages:
(1) suitability for industrialized production copper amino acid chelate, technique is simple, and manufacturing cost is low, without increasing visual plant, easy to operate, is easy to promote;
(2) good product quality, the feed good palatability of preparation, absorptivity is high, easily transports, and can strengthen the activity of animal body endoenzyme, improves the utilization rate of protein, fat and vitamin, thereby improves the growth performance of animal, has both been applicable to animal, is also applicable to fish.
