The present study indicated that higher content of dietary fiber in the flour by the incorporation of MPP may also have a role in the firmness ofmacaroni products. Earlier studies on addition of dietary fiber rich materials to semolina resulted in alterations in firmness of pasta. Brennan et al. (2004) reported that addition of inulin reduced the firmness of cooked pasta while Edwards et al. (1995) reported that addition of dietary fiber (water soluble arabinoxylans) did not give any changes in the textural properties of cooked pasta. On the other hand, Sozer et al. (2007) reported that the firmness of pasta (spaghetti) prepared from semolina enriched with wheat bran was higher than that of control. Statistical analysis indicated that firmness of cooked macaroni was positively correlated to cooking loss (r=0.91).
