The lactulose/furosine (Lu/Fu) ratio in UHT milks resulted to be around 16 times higher than in commercial powder milk samples so, the determination of the Lu/Fu ratio in freshly processed UHT milk seems to be useful to detect the presence of reconstituted milk.", pages = "737-739(3)", url = "http://www.ingentaconnect.com/content/iafp/jfp/1994/00000057/00000008/art00016" }
