Taint Detection in Milk with Lonestar

Lonestar is an easy to use and powerful analyzer for accurate, real time identification and monitoring of trace flavor contamination in milk including 2,4-dichlorophenol (DCP), 2,4-dibromophenol (DBP), biogenic amines such as triethylamine (TEA), milk adulterant benzoic acid and the milk age marker lactic acid.

Pesticide breakdown products such as 2,4-dichlorophenol (DCP) are found in trace amounts in the grass based feed of dairy cattle. DCP and other chlorinated phenols have a very strong ‘medicinal’ flavor and are detectable by the human palette in extremely small quantities. Compounds such as DCP can become concentrated in processed dairy products such as cheese, butter, yoghurt and cream. Due to the low initial concentration of the compounds in un-processed milk, detection can be difficult without skilled personnel performing expensive and time consuming analytical techniques such as HPLC-MS or GC-MS. Incorporating Owlstone’s proprietary FAIMS spectrometer, single or groups of contaminants in milk can be rapidly identified and quantified to enable red light / green light checks for quality control on the plant floor.

Rapid analysis time. Detection at part-per-billion ppb concentrations. Highly selective, reducing false alarms. Easy to use, operable by non-specialists. Fully portable device for point of use measurement.
