Crystallinity determination of amylose-fatty acid complex in gelatinized rice starch-fatty acid mixtures using Terahertz spectroscopy

Han Guo et al.

Summary: This study investigated the potential of terahertz spectroscopy for determining the crystallinity of gelatinized rice starch after complexing with lauric acid (LA) and palmitic acid (PA). The results indicate that the intensity of the peak at 12.0 THz can be used to accurately determine the crystallinity of amylose-fatty acid complex in gelatinized rice starch-fatty acid mixtures without interference from the presence of LA and trapped PA in the sample matrix.

Characterization of quinoa starch nanoparticles as a stabilizer for oil in water Pickering emulsion

Fan Jiang et al.

Summary: Quinoa starch nanoparticles (QSNPs) with a uniform size of 191.20 nm were prepared by nanoprecipitation. QSNPs, with amorphous crystalline structure, had a greater contact angle than QS with orthorhombic crystalline structure, making them suitable for stabilizing Pickering emulsions. QSNPs-based Pickering emulsions, formulated with suitable conditions (QSNPs concentration of 2.0-2.5%, oil volume fraction of 0.33-0.67), showed good stability against pH values of 3-9 and ionic strengths of 0-200 mM. The emulsion's stability was influenced by the structure of the starch interfacial film and the thickening effect of the water phase. The emulsion also exhibited excellent freeze-thaw stability and can be produced as a re-dispersible dry emulsion through freeze-drying.

Fabrication and characterization of octenyl succinate anhydride modified amylose with pH-responsive Pickering emulsion behavior

Pingping Wang et al.

Summary: In order to produce stable Pickering emulsion suitable for targeted delivery in the small intestine under stomach acid conditions, the emulsifying ability and pH responsiveness mechanisms of octenyl succinate anhydride modified amylose (OSA-AM) in formless and nanoparticle form were compared. The results showed that OSA-AM nanoparticles exhibited stronger ability to form stable Pickering emulsion compared to OSA-AMs. Additionally, the stability of the Pickering emulsion was found to be dependent on the pH environment, with OSA-AM nanoparticles showing increased stability in acidic conditions.

Rapid preparation of starch nanocrystals by the mixed acid of sulfuric acid and hydrochloric acid

Sai Li et al.

Summary: Waxy maize starch nanocrystals were prepared for the first time using a mixed acid of sulfuric acid and hydrochloric acid. The physicochemical properties, crystalline structure, and particle size of the starch nanocrystals were measured. The results showed that there was no significant difference between the nanocrystals prepared by mixed acid and sulfuric acid in terms of particle morphology, group structure, and surface elements. The yield of the nanocrystals prepared by mixed acid was lower but the preparation time was significantly shorter, and they exhibited higher crystallinity and smaller particle size compared to those prepared by sulfuric acid.

New indoleacetic acid-functionalized soluble oxidized starch-based nonionic biopolymers as natural antibacterial materials

Xugang Dang et al.

Summary: This study aims to develop a new soluble oxidized starch-based nonionic antibacterial polymer (OCSI) by grafting indoleacetic acid monomer (IAA) onto oxidized corn starch (OCS). The synthesized OCSI exhibits high thermal stability and solubility, with a substitution degree of 0.6. It shows significant bactericidal activity against both Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria, and can be blended with biodegradable polycaprolactone (PCL) to form antibacterial films (OCSI-PCL) with excellent mechanical properties and biocompatibility.

Acetalized starch-based nanoparticles stabilized acid-sensitive Pickering emulsion as a potential antitumor drug carrier

Qimeng Zhang et al.

Summary: In this study, drug-loaded, acid-sensitive Pickering emulsions were prepared using acetal-modified starch-based nanoparticles as stabilizers. The acetalized starch-based nanoparticles not only stabilize the emulsions, but also exhibit acid-responsive release characteristics, leading to the release of the drug in acidic environments and reducing particle accumulation. The resulting emulsions showed significant anticancer activity, suggesting their potential as antitumor drug carriers for enhanced therapeutic effects.

Evolution and critical roles of particle properties in Pickering emulsion: A review

Liangshan Ming et al.

Summary: Pickering emulsion is an emulsion that uses solid particles or colloidal particles as emulsifiers instead of surfactants, with unique properties such as high stability, low toxicity, environmental friendliness, and low cost. This study provides an overview of particles in Pickering emulsions, analyzing the critical evolution of these particles and discussing their influence on emulsion stability. The study also discusses the stabilization mechanism of Pickering emulsions and the challenges of interfacial particle detection techniques.

Influence factors of starch nanoparticles formation and their application in Pickering emulsion

Xiaoxia Yan et al.

Summary: Starch nanoparticles were prepared from native corn starch and corn amylose using two nanoprecipitation methods. The crystalline property was the main characteristic of these starch nanoparticles, and the particle size, morphology, FT-IR spectra, and contact angle were also investigated. The results showed that the mean size of native corn starch nanoparticles was smaller than that of corn amylose nanoparticles prepared by the two methods. The crystalline structure of all the starch nanoparticles was not significantly affected by the nanoprecipitation methods, but the corn amylose nanoparticles prepared by dropping ethanol into the amylose paste had a higher crystallinity and water contact angle. Pickering emulsions stabilized by these amylose nanoparticles exhibited a more concentrated particle size distribution and efficient dispersion on the oil droplet surfaces. Therefore, corn amylose nanoparticles prepared by dropping ethanol into the amylose paste have potential applications in stabilizing Pickering emulsions.

Summary: The study focused on the modification strategies, characteristics, and performance of starch nanoparticles (SNPs), as well as their practical applications, while pointing out the main limitations and recommendations. Chemical esterification and oxidation, as well as physical modification, are preferred methods for altering SNPs, resulting in changes in their functional groups. Tailoring properties such as size, shape, and hydrophobicity is key for the performance of nanoparticle-based systems in various applications.

One-step zwitterionization and quaternization of thick PDMAEMA layer grafted through subsurface-initiated ATRP for robust antibiofouling and antibacterial coating on PDMS

Xin Yu et al.

Summary: In this study, a thick PDMAEMA layer was successfully grafted on PDMS via subsurface-initiated atom transfer radical polymerization (SSI-ATRP), where the self-migration of DMAEMA monomers into PDMS subsurface was shown to be crucial. The thick microscale graft layer exhibited superior performance compared to nanoscale graft layers obtained by conventional methods, and simultaneous zwitterionization and quaternization of the PDMAEMA layer was achieved through a simple one-step process. The results indicated that a high zwitterionization degree and low quaternization degree on the PDMAEMA layer had a well-balanced effect on fouling repellence and bactericidal activity.
