The ratio of non-glutelin and non-prolamin proteins in rice. (A) The average ratio of non-glutelin and non-prolamin proteins (TP–G–P) in white rice grains with a 90% rice-polishing ratio for the seven rice varieties is shown (n = 28). (B) The average ratio of TP–G–P in the fractionated rice powder of different rice varieties is shown (n = 35). The ratio of TP–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
