Description
Technical field
The invention belongs to feed additive fields, and in particular to a kind of preparation method of feed methionine chelate ferrous iron.
Background technique
Microelement is one of essential nutrient during growth of animal, and initial microelement is with inorganic salts
Form is introduced directly into feed, such as ferrous sulfate, copper sulphate, although inorganic salts are water-soluble very well, in animal alimentary canal
Inside easily with phytate anion common in feed, oxalate anion by the intracorporal biochemical reaction form of animal formed it is corresponding molten
The salt of solution degree very little, is not easy by intestinal absorption.With the development of feed industry, trace mineral supplement amino-acid trace element is chelating
Object such as amino acid chelated iron, copper amino acid chelate, chelating amino acids manganese and zinc-amino acid chelate etc. is gradually developed, it
Feature is stable, efficient, small toxicity, and absorption easy to digest, is conducive to growth of animal in enteron aisle, can prevent and treat microelement deficiencies
Disease, improves the immunity of organisms of animal, and in feed nutrition composition using beneficial, also have high-protein agent concurrently
Effect.So-called chelate is exactly the complex compound with certain structure type, i.e., ligand can be matched with two or more
Position atom and the same central ion are complexed, and Chelates of Amino Acids And Trace Elements is in divalent metal and amino amino
Nitrogen-atoms formed coordinate bond, it is considered that amino acid is with trophism microelement: iron, copper, manganese, zinc etc. are usually formed ligancy
For 4 chelate, chela number of rings is 2, i.e., the molar ratio of amino acid and microelement is 2:1.The formation of chela ring cause chelating from
Son more difficult fractionation dissociation in aqueous solution than non-chelate ion, Chelates of Amino Acids And Trace Elements is because of its metal ion and amino acid
After molecule is combined by coordinate bond, so that its intramolecular charge is tended to be neutral, form more stable chemical structure, not only stability
Good, good fluidity, antagonism are few, into animal body in after in digestion process impacted factor it is small, convenient for body to metal from
Son is fully absorbed and is utilized, and the present invention is the product chelated using methionine and ferrous sulfate.
Summary of the invention
Present invention mainly solves the problem of be to provide a kind of method that methionine and ferrous sulfate chelated.Produce the production
The raw material that product use includes: methionine, ferrous sulfate, 10% sodium hydrate aqueous solution, dehydrated alcohol.
The present invention can be achieved through the following technical solutions:
A kind of preparation method of feed methionine chelate ferrous iron, it is characterized in that being made of following steps:
(1) methionine: ferrous sulfate: 20-22:10:68-70 is sent into chemical reaction kettle to water in molar ratio, and the temperature remains within the normal range, starts
Blender monitors pH value at any time, is 7.0-7.2, reaction time 0.8-1.0 hour with 10% sodium hydrate aqueous solution tune pH value.
(2) by reactant be sent into centrifugal separator separation, go the solid obtained after moisture removal be methionine chelate ferrous iron and
A small amount of ferrous sulfate not chelated obtains ratio in 1:1 at this time and dehydrated alcohol is added, not using methionine trace element chelate
It is dissolved in dehydrated alcohol, and ferrous sulfate is dissolved in the principle of dehydrated alcohol, and dehydrated alcohol recycling is filtered off after agitated and is reused, it is remaining
Be that methionine chelate is ferrous, obtain finished product after methionine chelate ferrous iron is sent into drying machine sealing drying 1.0-1.2 hours.
Methionine purity described in above-mentioned steps (1) is 98%.
The drying temperature of drying machine described in above-mentioned steps (2) is 50 DEG C -60 DEG C.
The beneficial effects of the present invention are:
(1) industrialized production methionine chelate is ferrous, and simple process, manufacturing cost is low, without increasing important equipment, operation side
Just, easy to spread；
(2) the feed palatability of product configuration is good, and absorptivity is high, easily transports, and can reinforce the activity of enzyme in animal body, improves albumen
The utilization rate of matter, fat and vitamin, to improve the growth performance of animal.
