Abstract: Alicyclobacillus acidoterrestris is a main spoilage bacterium causing contamination in acidic fruit due to its acidophilic and thermophilic resistance. Its spores have strong thermo-acidophilic resistance and can survive traditional pasteurization process,which presented a serious challenge on the sterilization process of the juice industry. Controlling contamination of A. acidoterrestris has become a common concern in the food research field and fruit juice industry. The characteristics,harm,identification and detection of A. acidoterrestris are summarized systematically in this review and the physical,chemical and physicochemical methods of controlling A. acidoterrestris spores pollution are introduced in detail,which would establishe the theoretical foundation for further study on the hazard control of Alicyclobacillus acidoterrestris spores.
