“…In the acid hydrolysis of starch, SNPs synthesis is affected by the size of native starch particles and acid interaction time. A remarkable enhancement by 50% in starch particle's crystallinity was found after 10 days of acid hydrolysis [14]. It was observed that the initial size of particles could promote the hydrolysis.…”

In the present study, an intensified approach for the synthesis of starch nanoparticles (SNPs) was demonstrated by using ultrasound-assisted acid hydrolysis method. The conventional acid hydrolysis for the synthesis of SNPs was intensified using ultrasound. The overall time required to convert starch granules to SNPs in the conventional acid hydrolysis method (48 h) was significantly reduced to 45 min by simultaneous acid hydrolysis and ultrasound irradiation. The acid concentration was found to be an important parameter for obtaining the desired size and morphology of the synthesized SNPs. The variation in the surface charges associated with the SNPs was confirmed through measuring their zeta potential. These potential charges on the surface of SNPs induce crystal growth among the synthesized nanoparticles. The irregular crystal morphology at higher acid concentration clearly shows SNPs' attachment with each other by coalescence. The higher crystallinity for SNPs was observed at low acid concentration; however, the lower acid concentration (0.5 M) leads to the smaller particle size of SNPs from 40 to 60 nm, with the overall yield of 23%. The proposed ultrasound method is more efficient and reproducible for the synthesis of SNPs for various applications.

“…90 Chemical modication of SNPs has been widely used to improve their properties via three important strategies namely chemical reactions with small molecules, the 'graing onto' strategy (i.e., graing of polymer chains in the presence of coupling agents), and the 'graing from' strategy (i.e., polymer chain graing by polymerization of monomers). 91 The chemical modication of SNPs in combination with another encapsulating material may address their instability and improve their application in the microencapsulation of probiotics.…”

“…The correlation coefficient (R2) was slightly larger for the adsorbent assay than for Freundlich isotherm. The action of IC adsorption on specific Adsorbents was observed as well [9, [29][30][31]. The parameter b refers to the interaction intensity between the adsorbent and the adsorbate.…”

Treatment of corn starch using pullulanase to prepare high yield of starch nanoparticles (StNPs) in a short time is one of the best ways of green industry of StNPs in comparison with other preparation procedures. Morphology of surface, particle size, function groups behavior and crystalline structure were investigated by using Scanning electron microscope (SEM), Dynamic light scattering (DLS), Transmission electron microscope (TEM), Fourier transforms infrared spectroscopy and X-ray diffraction. Starch nanoparticles can be used with chitosan to generate a novel composite to remove dyes from aqueous solutions. Indigo carmine dye was remediated with chitosan starch nanoparticle composite to evaluate the adsorption efficiency of such composite. Batch experiments were done to check the optimum pH, contact time, adsorbent dose, initial dye concentration and temperature to assess the kinetic data from isotherm of adsorption. The obtained results are fitted with pseudo second order and Langmuir isotherms. Free Gibbs energy (∆G°), enthalpy (∆H°) and entropy (∆S°) of the sorption parameters indicated spontaneous and endothermic adsorption process.
