Fig. 3 depicts the effects of extrusion variables on cooking time,
cooked weight and cooking loss of pea starch noodles. Cooking
time increased with increasing moisture content and screw speed
(Fig. 3A and B). Barrel temperature had little effect on cooking time
(Table 3). Cooking time was positively correlated with expansion
ratio (r = 0.76, p < 0.001) and percentage of gelatinised starch
(r = 0.66, p < 0.01), which was also positively correlated with
expansion ratio (Table 4)
