Kim, Jung, and Rhee (1998), who analyzed the relationship
between the time taken to wash rice and the texture of
the cooked rice, reported that the hardness of cooked rice
decreases with an increasing washing time, while the springiness
and cohesiveness do not change signiWcantly. Kim,
Lee, and Shin (1997) also reported that diVerences in color
and odor of cooked rice treated with three surfactants are
not signiWcant at the 5% level.
In conclusion, 250ppm chlorine, which had no signiWcant
inXuence on the sensory characteristics of cooked rice
compared to a control, is an eVective sanitizer to eliminate
coliforms in raw rice.
