AI Article Synopsis
- A new type of chestnut porous starch nanoparticle (PSNP) was created by combining features of regular starch nanoparticles and porous starch through ultrasonic and acid hydrolysis, resulting in smaller particle sizes and increased surface area.
- The PSNP, measuring 286.3 nm, exhibited superior adsorption abilities for substances like water, oil, and methylene blue compared to other samples.
- The synthesis method affected starch composition, increasing relative crystallinity and solubility while reducing total starch and amylose content, highlighting the PSNP's potential as an effective adsorbent for various bioactive materials and dyes.
Article Abstract
A novel chestnut porous starch nanoparticle (PSNP) was successfully synthesized, combining the properties of starch nanoparticle (SNP) and porous starch. The SNP obtained through ultrasonic and acid hydrolysis, exhibited a smaller particle size (173.9 nm) and a higher specific surface area (SSA) compared to native starch. After the synergistic hydrolysis by α-amylase and glucoamylase, the porous structure appeared on the surface of SNP. The prepared PSNP had a size of 286.3 nm and the highest SSA. In the adsorption experiments, PSNP showed higher capacities for adsorbing water, oil and methylene blue (MB) compared to other samples. The acid and enzymatic treatments resulted in a decrease in the levels of total starch content and amylose ratio. Furthermore, the treatments increased the levels of relative crystallinity (RC) and solubility, while decreasing the short-range ordered structure and swelling ratio at high temperatures. It was observed that the SSA of starch granules positively correlated with the MB and water adsorption capacity (WAC), solubility, and RC. These findings highlight the potential of the novel PSNP as an efficient adsorbent for bioactive substances and dyes.

To ameliorate the limitations of corn starch (CS) processing, Radix Paeoniae Alba polysaccharide (RPAP) was used to modulate the physicochemical and digestive properties of CS. The main purpose of this paper is to investigate the effects of RPAP on the pasting, rheological, thermal, structural, and digestive properties of CS. The results show that the addition of RPAP could increase the peak viscosity and final viscosity of CS gel, and RPAP could increase the apparent viscosity, storage modulus, loss modulus, hardness, and strength of CS gel, implying that RPAP can effectively improve the pasting and viscoelasticity properties of CS.

Article Synopsis
- Hydrothermal carbonization (HTC) transforms waste biomass, particularly high nitrogen feedstocks like kitchen garbage and blue-green algae, into valuable resources, but the characteristics of small hydrochar particles remain underexplored.
- Hydrochar particles show unique properties such as poor porosity, moderate pH, negative charge, and high hydrophobicity, which differ from the original hydrochar and secondary char derived from simpler biomasses.
- The study identifies complex formation mechanisms through various chemical reactions in the hydrochar microparticles, highlighting their potential as soil fertilizers and decontaminants while emphasizing that effectiveness is influenced by HTC temperature and type of biomass used.
