Adhesiveness or stickiness is related with the amount of
starch and starch gelatinization. In the early stages of cooking
adhesiveness values were found to be higher and it
decreased as cooking time proceeded (Table 4). Especially,
when its in the optimum cooking time region which is
roughly 12 min for each spaghetti type adhesiveness values
were lowest. Water cannot diffuse into inner layers up to
optimum cooking time and protein network does not
develop as a result starch leaches into cooking water easily.
During cooking, severe changes in the microstructure of
pasta occurs. The uniformity of dry pasta starts to change
by the diffusion of water from outside to the core. Closer to
the surface of the spaghetti strand the changes are more
drastic, starch granules are no longer intact as in the core
and protein matrix starts to break down due to denaturation.
Even the gluten matrix is still elastic enough in the
centre (Voisey, Wasik, & Loughheed, 1978). In general
adhesiveness values of bran
