Abstract

Textural properties of the cooked wheat noodles prepared from 5 Korean wheat varieties (Woori, Yeunpa, Allgeuru, Geuru, and Tapdong), and 3 foreign wheat varieties (ASW, WW and DNS) were evaluated by mechanical and sensory analyses, and their correlations to the physicochemical properties of the flours were examined. Cooking loss for noodle was negatively correlated with protein content, and weight increase during cooking showed a positive correlation with damaged starch content. From the mechanical tests, hard wheats (Tapdong and DNS) showed greater values for hardness, chewiness and tensile strength of the noodles than soft wheats. Foreign soft wheats (ASW and WW) showed relatively lower values for these attributes than the Korean soft wheats. Among the mechanical tests, multi-blade compression shear test had better correlations to the sensory characteristics than 10% compression, repeated compression and tensile tests. Among the flour characteristics, protein content was the most determining factor for the textural properties of noodle. Amylose increased the tenderness and slipperiness, but decreased internal firmness of the noodle. The Korean soft wheat noodles showed relatively darker color for the cooked noodle than WW or ASW. From acceptability test for noodle, Geuru was most preferred among the tested wheat varieties.
