preparation example Construction
[0021] The invention discloses a preparation method of low iron feed. The preparation method comprises the following steps:
[0022] Step 1: configure a complexing agent, use a 2% concentration of EDTA-2Na solution prepared in deionized water to configure with solution A to obtain a complexing agent; specifically, solution A can be prepared in deionized water with a concentration of 2%. Phytic acid solution, or tartaric acid solution with a concentration of 2% prepared in deionized water, or a tea polyphenol solution with a concentration of 2% prepared in deionized water, preferably, the volume of phytic acid solution and EDTA-2Na solution used The ratio of 1:1 is used to configure complexing agent, the volume ratio of tartaric acid solution and EDTA-2Na solution is 1:1 to configure complexing agent, and the volume ratio of tea polyphenol solution to EDTA-2Na solution is 1:1 to configure complexing agent. The prepared complexing agent forms a complex ion compound with the iron...
Embodiment 1
[0026] Perform operations as described above in experimental steps 1 to 3;
[0027] Step 1: configure a complexing agent, use a 2% concentration of EDTA-2Na solution configured by deionized water and a 2% concentration of phytic acid solution configured by deionized water, and the volume ratio of phytic acid solution to EDTA-2Na solution is 1: 1 configure and obtain a complexing agent;
[0028] Step 2: soaking, using the complexing agent obtained in step 1 to soak feed aniseed at 7.5L / kg, soaking for 48 hours at 25°C while mixing, and the stirring speed is 180rpm;
[0029] Step 3: Treatment, centrifuge the feed batch soaked in the complexing agent in step 2, discard the upper layer solution, use deionized water to stir and rinse the feed, repeat the centrifugal washing step until the complexing agent is washed, and the complexing agent will be removed. The feed aniseed is dried to obtain low-iron feed;
[0030] After the preparation is completed, the iron content in the feed...
Embodiment 2
[0032] Perform operations as described above in experimental steps 1 to 3; in this embodiment, the conditions selected are different from those in embodiment 1:
[0033] Step 1: In the configuration of the complexing agent, the 2% concentration of EDTA-2Na solution prepared by deionized water and the 2% concentration of tartaric acid solution prepared by deionized water are used, and the volume ratio of tartaric acid solution and EDTA-2Na solution is 1:1 configure and obtain a complexing agent;
[0034] Step 2: During soaking, use the complexing agent obtained in step 1 to soak feed aniseed at 7.5L / kg, and stir for 48 hours at 25°C, with a stirring speed of 180rpm;
[0035] After the preparation is completed, the iron content in the feed is detected.

Abstract
The invention discloses a low-iron feed preparation method, which comprises: 1, preparing a complexing agent: using EDTA-2Na and a phytic acid or tartaric acid or tea polyphenol solution to prepare the complexing agent; 2, soaking: soaking the aniseed of the feed by using the complexing agent obtained in the step 1, and stirring or shaking for 48 hours at 25 DEG C; step 3, treatment: performing centrifugal treatment on the feed aniseed soaked in the complexing agent in the step 2, discarding an upper-layer solution, stirring and washing the feed with deionized water, repeating the centrifugal washing step until the complexing agent is cleaned, and drying the feed aniseed without the complexing agent to obtain the low-iron feed. According to the preparation method, the whole raw material is treated instead of pure treatment of a certain raw material, and the iron residue in the rat food raw material can be reduced, so that the iron residue in the commercially available rat food is further reduced, and the low-iron rat feed with lower iron content is prepared.
Description
Technical field: [0001] The invention relates to the field of animal feed, in particular to a preparation method of a low-iron feed. Background technique [0002] In animal experiments, there are a large number of experiments that require the use of special feeds whose nutritional components are different from normal feeds. Low-iron feed is one of them. At present, the existing low-iron feed preparation method has unstable residual iron in the final feed. , the actual commercial low-iron rat feed, the iron content can not reach the low-content standard required for establishing an iron-deficiency model. However, the existing treatment methods are all aimed at a single raw material, such as EDTA-2Na treatment of casein, the control of iron pollution is the most important problem when establishing an iron deficiency model. Residues are not conducive to the establishment of iron deficiency models. [0003] For example, the publication number is: CN107279471A, the invention na...
