1)The values represent mean ± SD for three experiments.
2)SM: Saemimyeon
3)HA: Hanareum No. 4
4)MY: Milyang No. 328
5)MV: Measured value
6)PV: Predicted arithmetic average value of each rice flour.
7)The maker (*) indicates significant difference between the MV and PV by t-test. (p<0.05)
a-cValues in the same column with different letters superscripts are significantly different by Tukey’s multiple range test (p<0.05).
