2.7. Statistical analysis
Regression analyses of the relationships between the storage
period and the head rice yield, the stained rice content and the rice
color were performed, and the models with the highest R2 and
significance (P) values were selected. A comparison of the means
was performed using Tukey's test at a 5% level of significance using
an analysis of variance (ANOVA), except for thermal properties,
results of which were the means of duplicates.
