Efficacy of ultraviolet radiation as non-thermal treatment for the inactivation of Salmonella typhimurium TISTR 292 in pineapple fruit juice

The purpose of this study was to investigate the efficacy of UV-C treatment with the Dean Vortex technology to inactivate the presence of Salmonella typhimurium TISTR 292 in pineapple juice at three different frequencies (30, 35 and 40 Hz). The increasing of pump frequency was resulted an increasing...
