Alicyclobacilli are thermo-acidophilic, endospore forming, non-pathogenic bacteria which can grow and multiply in acidic products such as fruit and vegetable juices, concentrates, and beverages, to cell concentrations high enough to produce off-flavour and odour taints, leading to product spoilage. As they can survive the common product thermal processing, like pasteurisation, a problem for the food industry has recently arisen and has not been solved yet. The bacterial characteristics, the impact for food industry in terms of spoilage incidents, as well as the currently available methods of detection are reported in the present review article.
