“…Degree of substitution and RE reflect the chemical activity of starch (Chang et al, ). Table shows that the S, SP, and viscosities of the cationic starch prepared without HHP were slightly increased compared with native starch, although the degree of substitution reached 0.0192.…”

“…The Kjeldahl method was used to determine the nitrogen content of the cationic starches (Chang et al, ). Degree of substitution (DS) is calculated as follows:

DS = \frac{162 \times W}{14 \times 100 - 151.5 \times W}

In the formula, W stands for the difference of nitrogen content between cationic starch and common corn starch, %; 14 stands for the molecular weight of nitrogen, g/mol; 162 stands for the molecular weight of an anhydrous glucose unit (AGU) of starch, g/mol; 151.5 stands for the molecular weight of CTA, g/mol.…”

Background and objectives The chemical activity of starch granules is inert. The purpose of this study was to reveal the mechanism of producing high‐quality modified starch by advanced equipment. Findings There were pores and central cavities with loose structure in mung bean starch granules, so water could enter the starch granules through the pores under high hydrostatic pressure treatment. The starch molecules could be hydrated, and starch granules could even be gelatinized. The reaction efficiency (RE) of cationic starch increased to 32.20% and the other qualities (solubility, swelling degree, and viscosities) were significantly improved after 100 MPa treatment. The RE and other qualities of cationic starch changed differently after 200 and 400–600 MPa treatments. Conclusions High hydrostatic pressure could produce significant mechanochemical effect on starch granules, so the structures and properties of mung bean starch were changed markedly, and the quality of cationic starch was improved. Significance and novelty The mechanism of producing high‐quality modified starch by advanced equipment was revealed using mechanochemical theory, which could lay a theoretical foundation for the manufacture of high‐performance modified starch industrial equipment in the future.

“…one of the chemically modified starches, cationic starches that possess positively charged groups such as amino, imino, ammonium and phosphonium, and are widely used for water purification and non-food products (e.g. cosmetics and topical products) [5]. cationic starches are generally synthesized by reaction of native starch with cationic reacting reagents such as epichlorohydrine with triethanolamine.…”

The objective of this study was to verify the effect of certain new biocompatible additive on the stability and feasibility of the SLN using Glyceryl monostearate as lipid matrix. Cationic Starch, which is newly modified in organic chemistry laboratories, used with different ratios to show the effect on zeta potential of formulated nanoparticles using Triamcinolone acetonide as a model drug. Method of High shear homogenization was used for preparation of SLN utilizing a rotor-stator homogenizer. It was found that particle diameter of formulated nanoparticles shifted from nanosized to micronized with increase of amount of cationic starch used (2.5 to 10% w/w), while the zeta potential reduced although showing high negative values (-36 to -27 mV), indicating stability. The loading capacity and encapsulation efficiency of produced nanoparticles were reduced with increase of amount of cationic starch used. The influence of cationic starch on drug release from prepared formulae was studied using dialysis bag technique. Fourier Transformation Infrared Spectroscopy (FTIR) showed the absence of new bands for loaded solid lipid nanoparticles indicating no interaction between drug and cationic starch. Electron microscope of scanning technique indicated sphere form of prepared solid lipid nanoparticles with smooth surface. It was concluded that retardation of in vitro release and effect on simulated in vivo permeation through human skin were affected by using different concentrations of cationic starch as excipient that meantime, be used to reduce zeta potential and act as self-flocculating agent during formulation.
