Table 3.

Relative crystallinity of raw and extruded starch-cellulose mixtures.

CL (g/kg)	Crystallinity (%)
	Raw	After extrusion at 150 rpm	After extrusion at 250 rpm
0	19.1 ± 0.5e	9.4 ± 0.8d	8.9 ± 0.2c
50	22.1 ± 1.8d	12.4 ± 0.9c	10.0 ± 0.8c
150	27.2 ± 1.1c	17.0 ± 0.8b	13.7 ± 1.7b
300	28.8 ± 0.6b	21.8 ± 1.6a	20.2 ± 1.5a
Cellulose	61.8 ± 2.0a	NA	NA

All values are mean ± SD (n = 3); values with different letters within a column indicate a significant difference between means (P < 0.05). CL: Cellulose content.
