Production process of feed-grade ferrous glutamate

Abstract

The invention relates to the technical field of production of ferrous glutamate, and particularly discloses a production process of feed-grade ferrous glutamate. A wet synthesis process is adopted, iron and glutamic acid are used to react in a solution, a ferrous glutamate solution is obtained by controlling the reaction temperature and the reaction time, a ferrous glutamate product is obtained by cooling crystallization, surface moisture is removed by drying, and then screening is conducted to remove large-particle products to obtain the feed-grade ferrous glutamate. The process is low in energy consumption, green and environment-friendly, and does not generate substances polluting the environment, and various indexes such as product content and heavy metals can meet the quality requirements of feed-grade ferrous glutamate; as only heating and stirring are needed in the production process, complex operations such as ultrasonic are not needed, and the equipment cost is low; the synthesis process is carried out in water, no harmful by-product is generated, mother liquor can be recycled, organic solvent extraction is not needed, the process is green and environment-friendly, post-treatment is simple, and no three wastes are generated; and the synthesis process is environment-friendly, economical and efficient.

Description

technical field [0001] The invention relates to the technical field of production of ferrous glutamate, in particular the production process of feed grade ferrous glutamate. Background technique [0002] Trace elements are essential nutrients for animal growth and reproduction, mainly including copper, iron, manganese, zinc, cobalt, chromium, etc. Trace elements participate in a series of digestion, physiological and biosynthetic processes in the body. Mostly use inorganic trace elements in production practice at present, as ferrous sulfate, however, there are following defects in using inorganic trace elements: the one, bioavailability is low, and animals generally can only utilize the inorganic trace elements of 2-10% of adding amount Most of the elements are excreted from the body, causing environmental pollution. In addition, ionic metal elements are also easily affected by phytic acid, oxalic acid, and cellulose in the intestinal tract, further reducing their absorption...

Problems solved by technology

Mostly use inorganic trace elements in production practice at present, as ferrous sulfate, however, there are following defects in using inorganic trace elements: the one, bioavailability is low, and animals generally can only utilize the inorganic trace elements of 2-10% of adding amount Most of the elements are excreted from the body, causing environmental pollution. In addition, ionic metal elements are also easily affected by phytic acid, oxalic acid, and cellulose in the intestinal tract, further reducing their absorption rate. At the same time, the antagonism between elements also affects biological potency; the second is that inorganic trace elements can interact with lipids and vitamins to accelerate the oxidation of fat and vitamins, which is not good for the growth and development of animals; the third is high doses of trace elements (especially copper, zinc or iron, etc.) A large number of free radicals are produced during the absorption and tissue utilization of the small intestine, causing a cyclical chain reaction, and peroxides (such as hydrogen peroxide, etc.) are generated every cycle, and peroxides can damage DNA, RNA, mitochondrial membranes, and endoplasmic reticulum Membrane and cell membrane cause peroxidative damage, seriously damage the integrity of intestinal cell membrane, make intestinal villi atrophy, rupture, fall off, increase the depth of crypts, reduce absorptive cells and increase secretory cells, reduce nutrient absorption capacity, and intestinal repair function Weakened, resulting in stunted animal growth, lower feed utilization, lower disease resistance and stress resistance, and lower meat quality

[0005] However, the existing production techniques for synthesizing ferrous glutamate are limited to laboratory synthesis and are difficult to apply to actual production. Therefore, a production technique for feed grade ferrous glutamate is proposed.
