plots were obtained by using Statistica (version 8) (StatSoft, Inc.,
USA). Predicted values of rice noodle qualities were obtained using
Eq. (1).
The relationships between the responses (pasting, rheological
and textural properties) were judged by correlation coefficients of
determination (R2). The significance or P-value was decided at
a probability level of 0.05. The calculation of the optimum condition
was performed using a multiple response optimization method.
Condition variables were optimized compared to commercial rice
noodle flour (National Starch & Chemical Co., Ltd., Bangkok,
Thailand).
