ABSTRACT

The food processing industry is witnessing an increasing

interest in non-thermal food processing technologies such

as ultraviolet (UV) irradiation. Compared to thermal dis-

infection treatments, UV radiation may have fewer adverse

quality effects and lower operational costs. UV technology

is extensively used in water purification and wastewater

treatment owing to its high-throughput and continuous

nature of operation. These attributes are attractive to food

processing industry and UV processing is beginning to find

applications in fruit juice processing. However, UV pro-

cessing is still in its infancy and considerable research is

needed before more widespread commercialization can

occur. In this entry we will review UV technology as it

relates to juice processing, including the fundamental

science of UV, instrumentation, methods for measuring

the dose, and an overview of some of the research that

has been conducted on UV juice processing.
