Abstract
SummaryThe influence of dandelion root polysaccharide (DRP) on the retrogradation characteristics of corn starch (CS) in the process of storage was studied. Compared with native corn starch gel, the blue value (BV), hardness and syneresis were significantly decreased with the increasing of DRP concentration. Fourier transform infrared (FT‐IR) and X‐ray diffraction (XRD) showed that DRP addition inhibited the recrystallisation of CS during retrogradation. In addition, the dynamic rheological behaviours confirmed that DRP could enhance the shear stability and reduce the elastic properties of corn starch gel. These data showed DRP had potential application value in delaying starch retrogradation and improving food texture.
