Embodiment Construction

[0027] A detection method for quickly identifying copper methionine chelate and determining its stability, the detection method is as follows:

[0028] A detection method for rapid identification of copper methionine chelate:

[0029] Step 1: sample preparation, take the copper methionine chelate sample to be tested and grind it with a mortar until it passes through a 40-mesh sieve;

[0030] Step 2: Determination of copper element and methionine content, copper reference "GB / T13885-2003" Methionine reference "GB / T17810-2009" Determination of copper element and methionine content in the chelate sample, the results are compared with the labeled amount of the test sample Comparison shows whether its component content can reach the standard;

[0031] Step 3: Microscope inspection, observe the surface of the sample through a 20 times microscope to check whether there are black particles remaining in the original state and the ground state of the product. If there are no black part...

Abstract

The invention discloses a detecting method for fast identifying copper mothionine chelate and judging the stability of copper mothionine chelate, and relates and belongs to the field of fodder technology detection. The fast judging mode is based on the characteristic of copper mothionine chelat and the gastrointestinal tract environment of an animal. According to the detecting method, the total content of copper and methionine in copper mothionine chelate, the residual quantity of a copper source, the content of copper in a solution in different pH value conditions and the dissolving condition of copper mothionine chelate in pure water are measured, and the quality conditions of copper mothionine chelate produced by different factories are comprehensively compared and judged.

Description

technical field [0001] The invention relates to the technical detection field of animal nutrition and feed, in particular to a detection method for the identification and stability determination of copper methionine chelates produced by different manufacturers. Background technique [0002] Copper methionine chelate is a new type of feed additive. Many literatures have shown that copper methionine chelate has high utilization rate, can improve animal growth performance, enhance immunity and anti-stress ability, and at the same time, it can reduce The environmental pollution caused by mineral elements is a green and efficient feed additive with broad application prospects. [0003] The main steps of the existing method for detecting the copper methionine chelate are as follows: the sample to be detected is heated and dissolved, centrifuged and separated into precipitated chelated elements, soluble chelated elements and free copper ions. Soluble chelated elements and free cop...
