This study was conducted to investigate the effect of starch properties on the texture of cooked noodles from Korean wheat. The genetic composition of GBSS I (granule bound starch synthase I, called waxy protein) and puroindoline, which affect the amylose content and kernel hardness, was also evaluated. Waxy wheats carrying Wx-1 null alleles showed clearly different starch properties, high swelling power, pasting viscosity, breakdown and paste clarity, unsuitable texture of cooked noodles, and low hardness and springiness. Two partial waxy soft wheats carrying single or double null alleles at the Wx-1 locus gene, and Pina-D1a and Pinb-D1a alleles exhibited a softer and higher elasticity texture of the cooked noodles than Korean wheats carrying wild-type Wx-1 null alleles. There were no significant differences in the starch properties and texture of cooked noodles according to the puroindoline composition. A principal component analysis showed a strong negative relationship between the amylose content and starch swelling power, and these traits also improved the springiness and cohesiveness of the cooked noodles prepared from non-waxy Korean wheat. Joongmo2012, a double null partial waxy wheat, showed higher starch swelling power and springiness of the cooked noodles than other non-waxy Korean wheats.
