Abstract:

Storage of ultra high temperature (UHT) milk at high ambient temperatures gave rise to a decrease of the ratio of lactulose to furosine contents. 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.
