Abstract

Ready to Drink (RTD) mango nectar was subjected to pulsed electric fields (PEF) processing. The effect of process parameters including pulse frequency (70-120 Hz) and pulse width (15-24 s) on carotenes total plate count coliforms yeast and moulds and over all acceptability was studied using a response surface methodology. Mango nectar exhibited high retention of carotene content at higher frequencies and pulse widths as compared to lower levels. However severe PEF treatments reduced carotene content. Maximum inactivation of native micro flora (4.1 log CFU/ml) retention of carotene content (2100 g/100 ml) and over all acceptability (8.3) scores were obtained when PEF treatments were set up to 38.0 kV/cm for 24 s using bipolar pulses at 120 Hz.
