Effects of aging time of gelatinized starch on starch noodle quality The aging time was not significantly influence on color of dry noodle, except to yellowness which was decrease with increasing aging time; cooking time; rehydration and relative extension (Table 11 and 12). However, it was considerable effect lightness, cooking loss and extension modulus of cooked noodles. These results could be comparable to those of Kim [3] in which aging time was markedly effect to cooking loss and noodle texture. The starch retro gradation occurred during aging and effectively stabilized the starch chains in the gel matrix [15]. Therefore, as prolong aging time of gelatinized starch, there were more amylose or short-chain amylopectin molecules participated in retro gradation process, resulting in highly impact to noodle strength and cooking loss [2,3]
