摘要

This paper discusses alternative methods to pasteurization for reducing and/or eliminating Escherichia coli O157:H7 in apple cider. Many cider producers are small, producing 5000 gallons or less each yr. Pasteurization equipment can be a detriment financially, and heat compromises the sensory quality of apple cider. Nonthermal alternative methods of reducing pathogen levels in apple cider include ozone, pulsed electric fields, radio frequency electric fields, H2O2, spices and essential oils, UV light radiation, freeze-thaw cycles and combination treatments, chemical sanitizer washes and high pressure processing. Each process has advantages and disadvantages, depending on cost, efficiency and required equipment.
