The effect of pulsed light on the survival of E.coli MTCC 433 in tender coconut water was investigated. The sterilized liquid samples were inoculated with E.coli @ 1010 cfu/ml and treated with pulsed light intensities of 0.18, 2 and 5.6 W/cm2 for an exposure time between 0 and 15 sec. The results obtained were fitted with three different models such as log linear plus tail, Weibull and biphasic model. Biphasic model showed the best the performance with 7 smaller RSME values of 9 evaluated kinetics followed by Weibull model. Among the three models, biphasic model fitted well with the inactivation of E.coli MTCC 433 by using pulsed light treatment.
