Fig. 6

The ratio of glutelin to prolamin in rice. (A) The average ratio of glutelin to prolamin (G/P) in white rice grains with a 90% rice-polishing ratio from seven rice varieties is shown (n = 28). (B) The average ratio of G/P in the fractionated rice powders of different rice varieties is shown (n = 35). The ratio of G/P of rice-polishing ratios of 90–70% (C), 70–50% (D), 50–30% (E), and 30–0% (F) (n = 5, as crop year). Data containing different capital letters indicate significance by Tukey–Kramer HSD test at p < 0.01. Nonsignificance between groups is indicated as “n.s.” The p-value is shown in the inset. The double asterisk shows statistical significance by Tukey–Kramer HSD test with p < 0.01
