portant characteristics of foods and materials based on the senses of sight, smell, taste, touch and hearing [12]. The field of sensory science has gained tremendous attention as novel techniques are being developed and assessed continuously to evaluate its market potential. Some researchers have investigated the effects of ultrasound on juice shelf life and optimizing the extent of disinfection as a function of different operating parameters[13–16]. There has been significant work related to understanding the effect of operating parameters on the microbial log reduction using UV or ultrasonic irradiations [8,9,2,17–23]. Though a lot of work has been done on the application of ultrasound or ultraviolet irradiations during the processing of food, the combined effects of ultrasound and UV on fruit and vegetable juices has not been studied generally. The comparison of the sensory quality attributes of the products exposed to ultrasound either individually or in combination with UV irradiations with the thermal processing approaches has not been elucidated in details. Sensory evaluation
is imperative to ensure compliance with the quality and marketability of the processed food products [24]. The present work reports a detailed comparison of the sensory profile (based on a
set of consumers) of orange juices treated using ultrasound individually as well as in combination with ultraviolet irradiations with those treated using conventional thermal processing. The study concentrates on understanding the effects of processing and preservation on the sensory properties and consumer acceptability of treated orange juice by assessing the hedonic values of treated orange juice by sensory evaluations. The studies related to the analysis of the color attributes and the oxidation reduction potential (ORP) have also been performed.
