Starch digestibility	Amylopectin chain length distribution				Starch granule size (µm)
	Degree of polymerization (DP)
	6–12	13–24	25–36	37–50	< 5	5–15
RDSES	0.88**	− 0.93**	− 0.86**	− 0.84**	0.99**	− 0.78**
SDSES	− 0.76**	0.80**	0.71**	0.65**	− 0.83**	0.64
RSES	− 0.96**	0.99**	0.95**	0.89**	− 0.96**	0.89**
HIES	0.75**	− 0.86**	− 0.77**	− 0.79**	0.98**	− 0.66**
