Effects of phosphorylation on the chemical composition, molecular structure, and paste properties of Hedychium coronarium starch

Effect of phosphorylation of long‐chain inulin on the rheological properties of wheat flour doughs with different gluten

“…This could be attributed to the large steric hindrance of the introduced phosphate group, which results in the decomposition of large molecules into smaller soluble molecules during the esterification process. Furthermore, phosphate groups exhibit stronger hydrophilicity compared to hydroxyl groups (De Oliveira Xavier et al ., 2019). Notably, hydrogen bonds are disrupted at temperatures above 50 °C, leading to a significant increase in the solubility of PDFXL.…”

Limited Quadruple Modification of Various Starches in the Literature: Why?

“…[ 5 ] Furthermore, the NS of Hedychium coronarium has high tendency for retrogradation, which is unfit for certain industrial utilization and phosphorylation of the NS has been suggested as a means of mitigating these shortcomings. [ 6 ] It has been documented that the poor freeze‐thaw stability, thermal stability, and poor solubility of chestnut NS can be ameliorated by subjecting it to pregelatinization process. [ 7 ] High paste viscosity and low fluidity limit the wholesome utility of kudzu starch.…”

“…The granular structure disappears entirely due to gelatinization and retrogradation of the modified starch. [ 6 ] The granular surface of the autoclaved starch is rough as shown in Figure 2b, with large pores and loose structure for easy penetration and erosion by the next series of three enzymes. The surface of autoclaved/BA‐treated starch is smooth with relatively few smaller pores which look like a dense layered structure (Figure 2c) and finally the surface of the granules of the net product with absolute disappearance of surface pores appears dense showing a solid stone‐like structure (Figure 2d).…”

“…The surface of autoclaved/BAtreated starch is smooth with relatively few smaller pores which look like a dense layered structure (Figure 2c) and finally the surface of the granules of the net product with absolute disappearance of surface pores appears dense showing a solid stone-like structure (Figure 2d). [6] The problems associated with quadruple modification of various starches are enumerated in the following:…”
