Abstract
The invention discloses a kind of feed preparation method of tryptophan chelating selenium, this method belongs to feed additive field, and producing the raw material that the product uses includes: tryptophan, selenium powder, 10% sodium hydrate aqueous solution；Product is made by techniques such as the chelatropic reaction of the production of aqueous solution, tryptophan and selenium powder, separation drying, technological advantage is: industrialized production tryptophan chelating selenium, simple process, manufacturing cost are low；The feed palatability of product configuration is good, absorptivity is high, tryptophan has promotion feeding to animal, weakens stress reaction, improvement animal sleep, increases the antibody of foetal animal and young baby, improves milk animal lactation, reduces daily ration high-quality protein dosage, saves the effects of feed cost；Trace elements of selenium is most important to animal, it is the active constituent for constituting glutathione peroxidase, it can prevent beta Cell of islet Oxidative demage, keep its function normal, absorptivity greatly increases after promoting sugared part metabolism, reducing the glucose in urinating and hemoglobin level and tryptophan chelating.
Description
Technical field
The invention belongs to feed additive fields, and in particular to a kind of feed chelates the preparation method of selenium with tryptophan.
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 etc. is gradually developed, and its feature is stable, efficient, small toxicity, and absorption easy to digest, is conducive to animal in enteron aisle
Growth, can prevent and treat trace element deficiency, improve the immunity of organisms of animal, and have for the utilization of nutrition composition in feed
Benefit also has the effect of high-protein agent concurrently.The present invention is the chelate of tryptophan and selenium, and tryptophan is containing in indyl
Property aromatic amino acid, be essential amino acid in human body and animal life activity, to the growth and development of humans and animals, new old generation
It thanks and plays an important role, referred to as the second essential amino acid, it is that the third-largest feed after methionine and lysine adds
Add amino acid, as feed addictive, has promotion feeding to animal, weakens stress reaction, improvement animal sleep, can also increase
Foetal animal and the antibody of young baby improve milk animal lactation, reduce daily ration high-quality protein dosage, save the effects of feed cost；It is micro-
Secondary element selenium be to the life of animal it is extremely important, selenium be constitute glutathione peroxidase active constituent, it can prevent
Only beta Cell of islet Oxidative demage keeps its function normal, promotes sugared part metabolism, reduces the glucose and hemoglobin level in urine,
Be in animal feed one of indispensable microelement and tryptophan chelating after absorptivity greatly increase.
Summary of the invention
Present invention mainly solves the problem of be to provide a kind of chelate with tryptophan and selenium, produce the original that the product uses
Material includes: tryptophan, selenium powder, 10% sodium hydrate aqueous solution.
The present invention can be achieved through the following technical solutions:
A kind of feed chelates the preparation method of selenium with tryptophan, it is characterized in that being made of following steps:
(1) tryptophan: selenium powder: water in molar ratio 15-17:8:75-77 ratio be sent into chemical reaction kettle, the temperature remains within the normal range, opens
Dynamic 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) reactant is sent into centrifugal separator separation, removing the solid obtained after moisture removal is that tryptophan chelates selenium, by color
Propylhomoserin chelating selenium obtains finished product after being sent into drying machine sealing drying 1.0-1.2 hours.
Tryptophan purity described in above-mentioned steps (1) is 95%.
Selenium powder purity described in above-mentioned steps (1) is 90%.
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 tryptophan chelates selenium, and simple process, manufacturing cost is low, easy to operate without increasing important equipment,
It is easy to spread；
(2) the feed palatability of product configuration is good, and absorptivity is high, easily transports, tryptophan and selenium are abundant to the effect of growth of animal
It is played, selenium is one of indispensable microelement in animal feed, is the activity for constituting glutathione peroxidase
Ingredient, it can prevent beta Cell of islet Oxidative demage, keep its function normal, promote sugared part metabolism, reduce the glucose and blood in urine
Red eggs white level, tryptophan have promotion feeding to animal, weaken stress reaction, improvement animal sleep, can also increase animal tire
The antibody of youngster and young baby, improve milk animal lactation, reduce daily ration high-quality protein dosage, save feed cost the effects of, tryptophan and
Animal absorptivity greatly increases after selenium chelating.
