摘要： The effects of high -resistant starch (RS) content rice flour, psyllium husk powder (PHP), and psyllium powder (PP) on the edible quality and starch digestibility of rice noodles were investigated in this study. High -RS rice noodles showed lower digestibility but poor edible quality. With the addition of PHP and PP, high -RS rice noodles ' cooking and texture quality were improved significantly, especially the breakage rates, cooking losses, and chewiness ( P < 0.05). Compared to traditional white rice noodle 's estimated glycemic index (eGI) of 86.69, the eGI values for 5PHP-RN and 5PHP-2PP-RN were significantly decreased to 66.74 and 65.77, achieving a medium GI status ( P < 0.05). This resulted from the high amylose and lipid content in the modified rice flour and psyllium, leading to increase of starch crystallinity. Besides, based on the analysis of Pearson 's correlation, it can be found that PHP rich in insoluble dietary fiber (IDF) could improve high -RS noodle cooking and texture quality better, while PP rich in soluble dietary fiber (SDF) can further reduce the RDS content and its starch digestibility. Therefore, utilizing modified rice flour with an appropriate addition of PHP and PP can be considered an effective strategy for producing superior -quality lower glycemic index rice noodles.
