Problems solved by technology

The second generation of simple organic salts, although they have good stability, they still have antagonism with some nutrients
However, the stability problem in the rumen or monogastric acid environment has not been well resolved (Liang Jianguang et al., 2008)

[0078] 2. Preparation of small peptide chelated iron and inorganic iron

[0079] Extraction of total iron:

[0080] Weigh about 0.25g of sample into a crucible, place the crucible on a heating plate and heat until the sample is completely carbonized. Transfer the crucible to a muffle furnace that has been preheated at 550°C for 15 minutes and incinerate for 3 hours. After cooling, soak the contents of the crucible with 2ml of water. If there are many carbon particles, dry the crucible on a water bath, then put it into a muffle furnace for ashing for 2 hours, let it cool and add 2ml of water. Add 10 ml (1+1) hydrochloric acid, heat and boil until the contents are almost dry, be sure to avoid splashing the contents during heating. After dissolving the residue by heating with 5 ml (1+1) hydrochloric acid, cool it and quantitatively transfer it to a 100 ml volumetric flask. Take 1ml of the solution in a 100ml volumetric flask and make to volume.

Abstract

The invention discloses a preparation method and application of a small peptide chelated iron compound. The preparation method comprises the following steps: preparing a nutrient solution from a protein raw material, a carbon source and water and carrying out sterilization; inoculating bacillus and protease into the nutrient solution and then carrying out fermentation enzymolysis or enzymolysis fermentation so as to obtain small peptide fermentation liquor; continuing to add a water-soluble ferric salt and carrying out a chelation reaction under the conditions of a reaction temperature of 55 to 65 DEG C and a pH value of 5 to 6; and drying a reactant so as to obtain the small peptide chelated iron compound. According to the invention, the preparation method for the small peptide chelated iron compound has a high chelation rate, as high as more than 95%; the prepared small peptide chelated iron compound has good stability in the stomach of an animal, contains a plurality of bioactive components and has more comprehensive nutrients, so the small peptide chelated iron compound can be used as a feed additive to supplement trace elements for daily ration and improve immune functions of animals.

Description

technical field [0001] The invention relates to a preparation method and application of a small peptide chelated iron complex. Background technique [0002] In order to ensure the normal function of each cell, tissue, organ, gland and system, animals need specific trace elements. Trace elements are indispensable nutrients for animals. Adding certain high-quality and high-utility trace elements in the diet is beneficial to animals. Health and maximizing their productive potential are of paramount importance (NRC, 1998; Richards, 2008). [0003] Iron is the trace element that the human body needs the most. Most of it exists in red blood cells in the form of hemoglobin. It is one of the components of human muscle and iron-containing enzymes. Hemoglobin is the main component of red blood cells and is responsible for carrying oxygen to all parts of the body. , for metabolism. Iron plays an important role in embryonic and postnatal skeletal development. Like copper and zinc, iro...
