Macaroni-shaped pastawas produced in the pilot-plant (50 kg/h)
of DiSTAM, University of Milan. Flours from parboiled rice (brown or
milled) and water were blended in order to produce a mixture with
a final water content of 40%. After mixing (12e15 min), two different
extrusion processes were applied. Conventional extrusion was
carried out in a continuous press for semolina pasta production
(Braibanti, Milano, Italy). A jacket with cold water kept dough
temperature at about 50e55 C at an extrusion pressure of
10e11 MPa
