3.2. Sensory evaluation
After sanitizing raw rice, the eVects of the treatments on
the sensory properties of the cooked rice were determined.
Results are shown in Table 2. There were no signiWcant
(p>0.05) diVerences in appearance, odor, taste, and overall
acceptability between control and cooked rice for 250ppm
chlorine. The appearance of cooked rice after 2000ppm calcium
oxide treatment scored signiWcantly (p0.05) lower than the control
and all other treated cooked rice scores. The taste
scores of cooked rice after 24,000ppm hydrogen peroxide
and 35% alcohol treatments were signiWcantly (p>0.05)
lower than for the control and all other treated cooked rice
scores. The overall acceptability scores of cooked rice after
250ppm chlorine and 2000 ppm calcium oxide treatments
were signiWcantly (p>0.05) lower than all other acceptability
scores.
