“…The common XRD patterns of starch are A-type, B-type and C-type [ 23 ]. As shown in Figure 4 , the native pea starch had strong diffraction peaks at 15.3°, 17.3°and 23.1°, which were in accordance with the characteristics of C-type crystallization.…”

The effects of ultrasonic treatment on the structure and physicochemical properties of pea starch were investigated in this study. The results showed that ultrasonic treatment increased the hydrolysis rate and particle size of pea starch. In the process of treatment, there were some depressions and pores on the surface of pea starch granules. Although the crystallization type of starch was retained, its crystallinity decreased. The pasting temperature of pea starch remained stable after ultrasonic treatment, but its peak viscosity, trough viscosity, cold viscosity, breakdown viscosity and setback viscosity all declined significantly. The transparency of starch paste decreased, but proper ultrasonic treatment could improve the strength of starch gel. The obtained results can provide a reference for the physical modification of pea starch.

“…This kind variation is normal as esterification converts alcohol OH to ester group, decreasing polarity and hydrogen bond force, reducing molecule chain stacking regularity and rigidity, possibly inducing starch macromolecule shrinkage, leading collapse, changing oval shape to polygonal surface. 30,[32][33] In addition, the esterification product stacking is difficult to control, possibly showing messy aggregation with unordered arrangement, causing a layered relief appearance. It seems the change of post-esterified oxidized is more visible than the single esterified starch.…”

Esterification is a normal method for starch modification while reaction condition is not clear. Here, pure corn starch and vinyl acetate were chosen for starch esterification. Reaction conditions involving esterifying agent content, pH, reaction time and temperature were explored. Dess‐Martin periodinane (DMP) pretreatment was adopted to accelerate esterification. Main results reveal that a content of 30 wt% vinyl acetate, pH = 9, time as 1 h and temperature as 45°C is an optimized condition for vinyl acetate esterification and DMP oxidization can enhance it. After modification, variations in microstructure, surface morphology and macroscopic properties such as viscosity, transparency, adhesion property were explored by FT‐IR, XRD, SEM, TGA, UV–Vis, viscosity, and slushing experiments. Main results reveal that after esterification carbonyl groups were introduced, lattice plane occurred expansion, surface morphology was destroyed, water absorption capacity, viscosity, and gelatinization temperature decreased while transparency, thermal‐stability and adhesion property increased. DMP treatment enhanced the previous variations. It seems via a middle‐level DMP pretreatment and vinyl acetate esterification starch solution viscosity and gelatinization temperature decreased greatly while transparency and adhesion force increased greatly, possibly having a potential use in textile industry. For instance, using as slurry its manufacture cost can be decreased with decreased energy consumption, economical.
