Pearson's correlation analysis of NA, DMA, Fe, Zn and P concentrations in NS and CE‐1 white flour and ferritin production in Caco‐2 cells

	DMA (μmol/mg)	Fe (μg/g)	Zn (μg/g)	P (μg/g)	Ferritin (ng/mg protein)
NA (μmol/mg)	0.912 ** 0.002	0.440 0.276	0.239 0.569	−0.180 0.670	0.711 * 0.048
DMA (μmol/mg)		0.355 0.389	0.132 0.755	−0.145 0.732	0.812 * 0.014
Fe (μg/g)			0.893 ** 0.003	0.627 0.096	0.242 0.563
Zn (μg/g)				0.854 ** 0.007	−0.132 0.755
P (μg/g)					−0.433 0.284

Bold and non‐bold numbers represent correlation coefficients and P values, respectively. Asterisks denote significant correlation between factors for *P < 0.05, **P ≤ 0.01, ***P ≤ 0.001.
