Pasta products were prepared from semolina, with semolina substituted at the 20, 40, and 60% level by whole corn flour, either raw or processed in metal containers at 15 p.s.i. (121 C) for 15 and 30 min. Products from the semolina-corn flour mixtures were used, unsupplemented, or supplemented with either 8% defatted soy flour or 0.3% L-lysine. Both the resistance to disintegration and organoleptic evaluation tests indicated that maximum heat treatment applied to corn flour induced a significant (P less than 0.05) improvement in the quality of the products. Amino acid analyses and biological studies also revealed a significant (P less than 0.05) improvement in the protein quality of the pasta product prepared from the mixture containing 60% corn flour, supplemented with either of the supplements used. Improvement in protein quality was highly correlated (r = 0.98) with the available lysine content of the samples.
