Özet

© 2022 Elsevier LtdThis study evaluated the impacts of xanthan gum (XG), sodium alginate (SA), and XG-SA complex formulations on the pasting, rheology, structural properties, amylose content, and in vitro digestibility of debranched pea starch (DBPS) treated with pullulanase. The amylose content of DBPS increased from 34.24% to 49.35%. The resistant starch (RS) increased from 35.12% to 38.90%. Further, the addition of polysaccharides increased the viscosity of DBPS, and the fluidity of the DBPS gels was enhanced. The amylose content and relative crystallinity (RC) of the XG-added samples decreased. In contrast, the RC of SA and XG-SA samples increased from 38.34% to 40.97%–40.48% and 47.64%, respectively. Additionally, XG, SA, and XG-SA increased the RS content, and the highest RS content (52.65%) was noted for 1% SA. This study provides a theoretical basis and new insights about DBPS and polysaccharide applications in food and materials.
