Technical Abstract: Fruit juices, shell eggs and produce are all part of a healthy diet, but they can contain harmful bacteria. Fruit juices are typically pasteurized in a heat exchanger. This processing can degrade the quality of the juice. Thus, alternative nonthermal interventions are being developed including radio frequency electric fields, pulsed electric fields, ultraviolet light, supercritical carbon dioxide, and high pressure. Shell eggs may be pasteurized by hot water immersion; however, the vast majority is not due to cost. Again, alternative interventions are being investigated such as microwave and radio frequency heating. For the case of produce, the vast majority is washed which reduces the bacterial load, but there is great interest in developing better or additional interventions that could be used in combination. Some examples include ultraviolet light, supercritical carbon dioxide, and flash steam.
