“…While SNS samples all had two obvious diffraction peaks at 2θ of 13° and 20°, indicating that a V-type crystalline structure was generated . This was probably due to the presence of a single helix structure embedded with ethanol, which was caused by the loose A-type crystal structure after starch gelatinization and mechanical disruption . It was also interesting that these new peaks disappeared when microfluidic pressure was enhanced up to 150 MPa, but all peaks of SNS ×4–150 shifted 0.5° to the right, which showed the damage and remodeling effects of high pressure on crystal structure.…”

Nanostarch has attracted great attention owing to its high biocompatibility, easy availability, low sensitization, small size, and large specific surface area. However, most well-dispersed spherical nanostarches are currently produced under chemical surfactants. Here, we use controllable dynamic high-pressure microfluidization (DHPM) with a nanoprecipitation method to prepare smooth surface and homogeneous starch nanospheres (SNSs). Under the microfluidization condition in a homogenization cycle of ×4 and pressure of 100 MPa, the smallest particle size (67.1 nm) of SNSs with excellent dispersibility (PDI 0.307) was obtained. In addition, after DHPM treating, the crystal structure of starch was damaged. Also, V-type crystallinity was observed after nanoprecipitation, and side chains in starch were cut as performed in an inside-out mode to form small starch clusters. Notably, by mechanical forces, the positions of the OH groups of starch glucan rings were greatly motivated in the spectra of FTIR, 1H NMR, 13C NMR, and XPS. They were cross-linked with each other to form new microstructures of −C–O–C– groups. Furthermore, this should be highlighted for the importance of pressure and homogenization cycle conditions in order to prepare bioresource nanomaterials with well-dispersed properties according to food and nonfood applications like delivery systems.

Linear D‐glucans are natural polysaccharides of simple chemical structure. They are comprised of D‐glucosyl units linked by a single type of glycosidic bond. Noncovalent interactions within, and between, the D‐glucan chains give rise to a broad variety of macromolecular nanostructures that can assemble into crystalline‐organized materials of tunable morphology. Structure design and functionalization of D‐glucans for diverse material applications largely relies on top‐down processing and chemical derivatization of naturally derived starting materials. The top‐down approach encounters critical limitations in efficiency, selectivity, and flexibility. Bottom‐up approaches of D‐glucan synthesis offer different, and often more precise, ways of polymer structure control and provide means of functional diversification widely inaccessible to top‐down routes of polysaccharide material processing. Here we describe the natural and engineered enzymes (glycosyltransferases, glycoside hydrolases and phosphorylases, glycosynthases) for D‐glucan polymerization and show the use of applied biocatalysis for the bottom‐up assembly of specific D‐glucan structures. We further show advanced material applications of the resulting polymeric products and discuss their important role in the development of sustainable macromolecular materials in a bio‐based circular economy.This article is protected by copyright.
