The present work investigates the effects of novel non thermal processing based on ultrasound on the
sensory profile of orange juice and also compares the observed trends with the conventional thermal pasteurization.
A novel treatment methodology based on combination of ultrasound and UV irradiations was
investigated. The juice quality was assessed in terms of standard parameters (taste, flavor, odor, mouth
feel etc.) by panel tests. Physicochemical analysis in terms of color of processed juice (which is an important
physical attribute) and oxidation reduction potential (a good indicator of the quantum of oxidants
present in the fruit juices) has also been performed. Thermally treated juices had significantly different
characteristics that were not very appealing as compared to the ultrasound treated juices or those treated
using the combined approach. The sensory properties of the ultrasound treated juices showed that the
samples were most acceptable to the consumers and rated at par with the quality parameters of the fresh
untreated juices. Overall the present work is the first to report and conclusively establish the usefulness
of ultrasound based treatment approaches for maintaining the sensory profile in comparison with the
thermally processed juice.
