Khoonphal (Haematocarpus validus) is an underutilised fruit with a delicately flavoured juice considered to have therapeutic properties. The present work aimed to evaluate the overall acceptability of the juice after different treatments using the fuzzy logic approach. The effects of ultrasound, microwave and conventional thermal treatment on sensory attributes were studied. Twenty trained panellists were considered for the sensory evaluation of the juice samples. Results from the fuzzy modelling showed that sample 4 (ultrasound assisted microwave treated sample) was the most acceptable and ranked as “very good” as compared to the other samples. The ranking of the juice samples in the increasing order of acceptability was T₄ > T₃ > T₁ > T₂ while the rank order of the quality attributes was colour > taste > flavour > mouth Feel. The results of the quality attributes showed that the highest importance was obtained for colour while the least was for mouth feel.
