“…The micrographs revealed that starch nano-particle granules are irregular in shape, size with no uniform pattern, which has been ascribed to the cavitation phenomenon inducing very high pressures and shear forces responsible for degradation of the external crystalline and amorphous layers of starch granules and therefore small segments can be produced. The surface appearance change was also observed in oat starch nano-particles by Falsafi et al 37 . HSP and LSP showed uneven exterior with voids and their granular structure was found to be disrupted to large www.nature.com/scientificreports www.nature.com/scientificreports/ www.nature.com/scientificreports www.nature.com/scientificreports/ starch nano particles from novel methods like ultra-sonication and alkali hydrolysis enhances hydroxyl, superoxide anion radical scavenging capacity, chelating iron ion ability, reducing power and introduction of substitution groups (sulfate groups) into polysaccharide molecules that has been regarded to increases the hydrogen bonding ability of polysaccharides 38 .…”

in this report, synthesis of the starch nanoparticles from underutilized and cheap sources viz: Horse chestnut (HS), Water chestnut (WS) and Lotus stem (LS) by using mild alkali hydrolysis and ultrasonication process has been presented. The particles were characterized by Differential scanning colorimeter (DSC), X-Ray Diffraction (XRD), Rheology, Scanning electron microscopy (SEM) and Fourier transform infra-spectroscopy (AtR-ftiR). the particle size measurements, functional properties and antioxidant potential of starch nanoparticles were also analyzed. the experimental results revealed that the average particle size diameter of Horse chestnut starch nanoparticles (HSp), Water chestnut starch nanoparticles (WSP) and Lotus stem starch nanoparticles (LSP) was found to be 420, 606 and 535 nm, respectively. We observed a notable increase in the water absorption capacity but decreased capacity for oil absorption in the starch nano-particles. SeM images revealed damaged starch granules after size reduction. Additionally, loss of crystallinity and molecular order was observed from XRD and AtR-ftiR spectra. it was concluded that the starch nanoparticles have better thermal stability, increased viscosity and antioxidant properties. Starch is a natural biopolymer, which is abundantly found in nature and also major component of our daily diet. It is mainly found in plant roots, staple crops and cereals such as rice, maize, wheat, barley, corn, tapioca, potato and others 1. Starch is composed of linear chain molecule; amylose and branched chain molecule; amylopectin. These two starch components are assembled in the form of granules with the size ranging from 1 to 100 µm 2. Starch has various applications, it has been used as thickening, gelling, stabilizing in a wide variety of foods and non-food products 3,4. Starch is also used for drug and bioactive delivery systems 3,5,6. The native form has however many limitations such as poor solubility, retro-gradation, limited digestibility and poor functional properties. For this reason, various physical, chemical and enzymatic methods have been employed to reduce these limitations or to add new attributes. Currently, starch nano particles are gaining more interest for improved quality and wide applications. They have been considered as the promising biomaterials for novel utilization in foods, cosmetics, and medicines as well as various composites 7. There are various techniques for starch nano particle preparations including hydrolysis by acid, enzymes or combination of two, regeneration and mechanical treatments using extrusion, irradiation, ultrasound or precipitation by co solvent 3,8. The easy and cost-effective methods for starch and starch derivative nanoparticles are always of paramount importance. Among various such methods, nano-precipation and ultra-sonication are very simple and reliable methods for nanoparticle production with desired size. The precipitation process involves a drop wise addition of a dilute starch solution into a non-solvent and ultra-sonication redu...

“…Similar results were reported for sonicated corn starch [13] . Studies have shown that high-intensity ultrasonication causes severe physical damage on the granular surface, by creating fissures or cracks, thereby increasing the ability of the granules to retain more water [31] . The increase in swelling power as a consequence of ultrasonication may be explained by disruption of the crystalline molecular structure of starch and bonding of water molecules to free covalently bonded hydroxyl groups of amylose and amylopectin [32] , and morphological changes as a result of increased cavitation leading to permeation of water into the granules [33] .…”

Highlights High-intensity ultrasound treatment of rice starch was conducted at different process temperatures. Severe ultrasound treatment conditions led to complete gelatinization of rice starch. Ultrasound treatment enhanced rheological and textural properties of starch-based sauces. Ultrasonication improved the freeze/thaw stability of starch-based sauces. Ultrasound treated starches are potentially applicable in the formulation of starch-based sauces.

“…Owing to the complicated behavior of materials at the nanometric scale, applying effectual, structural characterization methods could open up a complete gamut of novel visions to enhance our insights concerning the character of nanodelivery systems in vitro/in vivo. Essentially, structural characterization is a fundamental part of research in quality assessment of nanodimensional delivery vehicles, which assists to predict carrier–bioactive interactions, bioactive delivery efficacy, and therefore the behavior of a therapeutic/vehicle within biological surroundings (Al Hagbani, Altomare, Kamal, & Nazzal, 2018; Alam et al., 2013; Falsafi et al., 2019).…”

“…To characterize various bioactive‐loaded nanocarriers, informative and influential techniques such as XRD have been implemented for reliably assessing their configurational attributes and offering unique information concerning their crystallization processes. XRD has demonstrated great potential in characterizing crystalline/amorphous architectures, crystalline lattice parameters, crystal growth, composition profile, nucleation, and even polymorphism of nanostructures (Falsafi, Maghsoudlou, Alami, et al, 2019), as summarized in Table 3.…”

With the emergence of nanocarriers for offering smart transformers improving the bioavailability and functionality of food bioactive compounds, a critical issue is experimental and analytical evaluation of the bioactive-loaded nanocarriers; so, further technical advancements are necessary for the precise structural characterization of these nanodelivery systems and application of sophisticated analytical techniques. Here, we have portrayed the current progress in the structural characterization approaches including X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis, fluorescence spectroscopy, circular dichroism, Fourier-transform infrared spectroscopy, nuclear magnetic resonance, X-ray photoelectron spectroscopy, and small-angle X-ray scattering/small-angle neutron scattering as powerful and informative tools to have a better control on the design, development, and appraisal of nanoengineered bioactive delivery systems. Different examples and case studies have been tabulated along with illustrative and schematic representation of relevant results. An emerging view concerning the challenges for future structural characterization of these systems is also discussed in detail.
