Abstract
Fresh wet rice noodles (FWRNs) are a popular staple food in southern China. The quality of rice varieties results in the inconsistent quality of FWRNs. However, evaluation of rice adaptability for the production of FWRNs is not comprehensive due to the absence of unified screening standards. In this study, twelve rice varieties in southern China were selected to analyze the correlations between rice's physicochemical properties and the quality characteristics of FWRNs. Results showed that KIM, GC, and IZG rice exhibited a high chalky grain rate and low gel consistency, while the related starches had a high amylose content, high setback value, and low short-range order. Their noodles achieved high total sensory scores and exhibited high levels of sensory and textural qualities. Correlation analysis revealed that the chalky grain rate, chalkiness degree, protein and fat contents, and amylose content were significantly and positively correlated with the hardness, elasticity, chewiness, and total sensory score of FWRNs. Therefore, based on the structural parameters of KIM and GC rice, amylose content between 26-28% and gel consistency between 33-36 mm would be the key factors for raw rice to make high-quality FWRNs. These results offer theoretical guidance for rice selection in the industrial-scale production of FWRNs.
