Abstract
The brilliant black reduction test (BRT) is a first and rapid screening test routinely used across the German dairy industry for the detection of antimicrobial substances, especially antibiotics, in cow's milk samples. This study aimed to determine if the three test systems BRT Inhibitor Test, BRT MRL-Screening Test and BRT hi-sense can also be applied to buffalo and horse milk. For buffalo milk, the detection limits of all antibiotics under investigation were at or below the European maximum residue levels (MRL). Previous freezing of the antibiotics in buffalo milk showed comparable results. While the BRT hi-sense is not recommended for horse milk, detection limits at or below the MRL were reached with the BRT Inhibitor Test and/or the BRT MRL-Screening Test for penicillins, neomycin, gentamicin, as well as streptomycin (BRT MRL-Screening Test only). In general, it must be noted that the incubation times of the test systems need extending compared to cow's milk and that horse milk must be heated before application.
期刊介绍:
The International Dairy Journal publishes significant advancements in dairy science and technology in the form of research articles and critical reviews that are of relevance to the broader international dairy community. Within this scope, research on the science and technology of milk and dairy products and the nutritional and health aspects of dairy foods are included; the journal pays particular attention to applied research and its interface with the dairy industry.
The journal''s coverage includes the following, where directly applicable to dairy science and technology:
• Chemistry and physico-chemical properties of milk constituents
• Microbiology, food safety, enzymology, biotechnology
• Processing and engineering
• Emulsion science, food structure, and texture
• Raw material quality and effect on relevant products
• Flavour and off-flavour development
• Technological functionality and applications of dairy ingredients
• Sensory and consumer sciences
• Nutrition and substantiation of human health implications of milk components or dairy products
International Dairy Journal does not publish papers related to milk production, animal health and other aspects of on-farm milk production unless there is a clear relationship to dairy technology, human health or final product quality.
