This paper is focused on new methods for inhibiting Alicyclobacillus acidoterrestris spores germination in apple juice concentrate. Four methods such as pulsed electric field (PEF), ultrasound (US), integrated method of PEF and US and microwaves (MW) have been investigated. The highest efficiency of spores inactivation was obtained after microwave treatment.
