“…When Ge et al used lowtemperature plasma to treat red bean starch, they also found that the crystallization mode of modified starch did not change, but the crystallinity of starch usually decreased [6] . The pH value of corn starch and cassava starch and the water-binding capacity and swelling capacity increased [7] . Du et al modified cassava starch with plasma and found that the solubility of the starch was significantly increased.…”

Starch, as a cheap and renewable biological material, has been widely used in the chemical industry, oil drilling, and other fields. However, there are still some shortcomings in natural starch, which often needs to be modified by some methods. The development and application of modified starch have attracted much attention. The use of low-temperature plasma methods to modify starch has gradually attracted widespread attention because there is no chemical impurity residue. DBD is a type of discharge that produces low temperature plasma. At normal temperature and pressure, plasma can be generated in a DBD reactor which uses air as discharge gas and adopts various electrode structures such as wire-column and plate-plate. The high-energy electrons, reactive nitrogen, and reactive oxygen species generated in the discharge can break chemical bonds when they act on the surface of biological materials, and then change the surface topography and physical and chemical properties of the materials.

“…Additionally, there were significant modifications in amylose concentration, paste clarity, solubility, freezing thaw stability, color characteristics, whiteness index, molecular weight distribution, and in vitro digestibility, depending on the cold plasma voltage and treatment time. Also, Chauhan et al [25] investigate the impact of pin-to-plate cold plasma at atmospheric pressure on physicochemical, functional, powder flow, thermal, and structural factors. The study demonstrates that a reduction in the amylose concentration through plasma-induced depolymerization resists the tendency for retrogradation and increasing paste clarity.…”

This paper presents the simulation results for dielectric barrier discharge (DBD) at atmospheric pressure in argon gas for different relative permittivity, granule shape, thickness layer, and granule diameter measurements for starch on the breakdown voltage. DBD is commonly utilized to generate cold plasma for starch modification. The electric field was computed using COMSOL Multiphysics 5.3a software. The breakdown voltage was calculated employing Paschen’s law for this electric field. The voltage was found according to the breakdown criterion for gap distance 0.2–1.0 cm, and then the Paschen curve could be plotted. The results show that the top electrode of the plasma system may be replaced with the parallel plate electrode by a mesh electrode with a bigger mesh size to achieve a lower breakdown voltage. In addition, increasing the relative permittivity and decreasing the thickness layer can reduce the applied voltage for plasma formation. When compared to the sphere and ellipsoid shapes, starch with a polyhedral granule shape requires a significantly lower voltage for breakdown. The starch granule diameter does not affect the breakdown voltage. These findings can be utilized to determine the optimal breakdown voltage for each type of starch modification, contributing to the construction of a high-efficiency plasma production system for starch modification.
