Ozone Treatment, Cauliflower, DisinfectionAbstract
The study focused on the effect of ozone treatment on cauliflower and to determine an optimum treatment
time for effective disinfection without alterations in the keeping quality and sensory attributes of the treated
sample. A domestic bubbling ozone generator was used in this experiment. To assess the time required for
disinfection, four time intervals were tested with an interval of 5 minutes upto 20 minutes.Treated samples of
cauliflower were analysed for microbial tests, keeping quality and sensory evaluation. Microbial tests showed
a prominent decrease in microbial population after each treatment. Also, the keeping quality of the treated
samples under refrigeration and room temperature gave a satisfactory score for freshness. Sensory evaluation
for ozone-treated samples was conducted to examine the changes in the sensory attribute after variation.
Among the different time intervals, 20 minutes of disinfection with ozone had a better score than other time
intervals in all the experiments.
