Tensile parameters, tensile strength and breaking length of cooked noodles made from wheat flour and
supplemented with Riceberry flour are compared in Table 5. The tensile strength and breaking length were
significantly different with the variation of Riceberry flour content increased. The results indicated that tensile
strength increased while breaking length decreased when the Riceberry flour content increased. That was noodles
from Riceberry flour had higher hardness and lower elasticity than noodles from wheat flour. It might be due to the
fact that the Riceberry flour had lower protein content than wheat flour (Table 1). Furthermore, the major protein in
Riceberry flour is in the form of protein body, which makes them unavailable to form network during dough
formation. The addition of Riceberry flour, a non-gluten flour, in the fabrication of noodles diluted the gluten
strength of the wheat flour and interrupted as well as weakened the overall structure of noodles (Kovacs, Fu, Woods,
& Khan, 2004).
