4. Conclusions
The results illustrate that the use of DF to replace durum wheat
semolina may be possible in order to obtain pastas with high DF
contents. However, the addition of DF individually and in combination
affected cooking, textural and colour characteristics. Over
all, the presence of DF in pasta led to an increase of OCT, CL, WA and
SI and to deterioration in textural characteristics. Moreover, raw
pasta enriched with DF showed a darker colour than semolina pasta
control. In the cooked pasta this trend changed; in fact, all inulin
enriched pasta (except for GR-P samples) showed higher L* value
than semolina pasta. Our data suggests an improvement in cooking
characteristics when oat bran flour is added in combination with
another DF; whereas a negative effect is observed when psyllium
fibre was added in combination with DFs. Further studies were
carried out in order to understand if a synergetic or antagonistic
effect can be appreciated on the predicted glycaemic response
