Beta-Agonists Residue Testing Service

Beta-agonists residues in foods of animal origin may affect consumer health. Creative Proteomics provides a platform for the analysis of Beta-agonists residues, and can customize different detection schemes for you according to different detection purposes.

Beta-agonists (β-agonists) are a class of phenylethanolamine synthetic compounds with adrenaline function, and all have the nucleus of phenylethanolamine in structure.

When the dosage of β-agonist drugs exceeds the therapeutic dose by 5 to 10 times, it can promote the redistribution of nutrients in cattle, pigs, sheep, poultry and other farmed animals. It can increase fat catabolism and protein synthesis in animals, significantly increase the lean meat rate of the carcass, and improve the daily weight gain and feed conversion rate of breeding animals. However, the wrong application of high-dose β-agonist drugs is likely to remain in the tissues of edible animals. When the cumulative dose in the human body exceeds a certain value or eats the visceral tissue with high residue (100 ng/g), the toxic side effects of β-agonists are prone to occur.

In the United States, rationally used β-agonists have been approved by the FDA for use in cattle, which can increase the efficiency of beef production by increasing muscle growth. The European Union bans all β-receptor agonists used for animal growth promotion, and only allows clenbuterol hydrochloride to be used for therapeutic effects. At the same time, in order to protect the interests of consumers, EU officials have also established maximum residue limits (MRLs). The MRL in cattle or horse meat is 0.1 μg/kg; the MRL in internal organs (liver and kidney) of cattle or horses is 0.5 μg/kg; the MRL of clenbuterol in milk is 0.05 μg/kg.

Accurate detection of β-agonist residues in food samples or feed may be necessary to protect consumer health and comply with food import and export inspections. Creative Proteomics has developed rapid detection technologies suitable for β-agonists residue testing service for manufacturers, enterprises, and government organizations. We strictly abide by the quality assurance/quality control plans and regulatory requirements of each country and region to provide you with support. Including but not limited to the following standards and methods: ISO, FDA, AOAC, EU regulations.

Food Beta-Agonists Residue Testing Platform

  • ELISA

Antigens or antibodies can be linked to enzymes by covalent bonds to form enzyme conjugates. After the enzyme conjugate is bound to the corresponding antigen or antibody, the color reaction of the added substrate can be used to determine whether there is an immune response. The intensity of the color response is directly proportional to the amount of the corresponding antigen or antibody in the specimen. Therefore, the test results can be displayed according to the degree of color development of the substrate.

  • LC-MS/MS

Enzymatically hydrolyze the remaining β-agonist in the sample. Adjust the pH value with perchloric acid solution. The protein is precipitated and then centrifuged. The supernatant is purified by electrospray ionization, liquid chromatography-tandem mass spectrometry and quantified by internal standard method.

Acceptable Samples: Dairy products, muscle (certain species), liver (certain species) and urine.

At Creative Proteomics, our analytical scientists are experienced in β-agonists residue testing. After communicating with you about the testing scheme, we will implement it within a quick turnaround time and provide you with an analysis report. If you have any questions or specific needs, do not hesitate to contact us.
