The antibiotic residue in the milk powder was detected by the Smartongue electronic tongue, and it was concluded that the milk powder solution without antibiotics and the milk powder solution with antibiotic added can be well distinguished on the principal component map. Moreover, different types of antibiotics are far apart from each other, and the difference is greater. The difference between neomycin and other antibiotics is the biggest, the difference between lincomycin and spectinomycin is small, and the difference between chlortetracycline and spectinomycin is large.
