Problems solved by technology

At present, the essence of the standard method commonly used by feed mills is still the Kjeldahl method, but because the crude protein determination process is relatively complicated, many feed enterprises do not know how to analyze when the results are abnormal during the actual detection process; Inaccurate test results lead to inaccurate test results. In the process of feed production and sales, various supervision departments of the government have failed to pass the sampling inspection, causing losses to the production enterprises.

Embodiment 1

[0030] 1. Instruments and equipment: the same as those used in the national standard "GB / T6432-1994" method.

[0031] 2. Reagents:

[0032] Mixed solution: Measure 100mL of distilled water and pour it into a beaker, slowly add 200mL of concentrated sulfuric acid, then add 300mL of 30% hydrogen peroxide after cooling, mix for later use.

[0033] Mixed catalyst: Weigh 10g of analytically pure copper sulfate, 100g of potassium sulfate, and 0.2g of selenium powder, put them into a mortar, grind them finely and pass through a 40-mesh sieve, mix well and set aside.

[0034] Other reagents are the same as those used in the national standard "GB / T6432-1994" method.

[0035] 3. Selection and preparation of samples: Select a representative sample and reduce it to 200g by quartering method. After crushing, all of them pass through a 40-mesh sieve and are placed in a sealed container to prevent changes in the composition of the sample.

[0036] 4. Analysis steps:

[0037] 4.1 Sample di...

Abstract

The invention discloses a feed protein detection method and aims to provide a protein detection method high in analysis speed and accurate in data analysis.The feed protein detection method is characterized by including the steps of 1, sample digestion, 2, ammonia distillation, 3, detection of the distillation step, 4, titration, 5, blank determination, and 6, calculation.The feed protein detection method belongs to the technical field of chemical detection.

Description

technical field [0001] The invention relates to a method for measuring protein, in particular to a method for detecting protein in feed, and belongs to the technical field of chemical detection. Background technique [0002] Animals such as poultry and aquatic products need feed protein in fact they need amino acids. Adding amino acids from exogenous sources to adjust the amino acid balance in the feed is the best way to improve the utilization efficiency of feed protein, save protein resources and reduce feed cost. Protein is a routine nutritional index that must be measured when identifying feed quality. At present, the essence of the standard method commonly used by feed mills is still the Kjeldahl method, but because the crude protein determination process is relatively complicated, many feed enterprises do not know how to analyze when the results are abnormal during the actual detection process; Inaccurate inspection results lead to inaccurate test results. In the pro...
