Moisture content of deep fried rice crackers mixed with fish powder (5, 10 and 15 g/100 g) and without fish powder ( control sample) were not significantly different (P < 0.05) at frying times in the range of 40–140 s (Table 2).
At the beginning of frying (20 s), the moisture content in control samples was higher than in other samples due to their higher water holding capacity.
Fish powder is high in protein content, which reduces the water holding capacity of protein-starch mixture during heating as reported
by (Skipnes, Iesel Van der, Ann, & Marc, 2008).
