In order to develop starch hemostatic materials with excellent hemostatic properties, the preparation of crosslinked porous starch (SPS) with sodium trimetaphosphate (STMP) as cross-linking agent was studied in this paper. When the solid-liquid ratio of porous starch (PS) was 30%, the mass ratio of cross-linking agent to starch was 0.04-1, and the SPS was crosslinked at pH 10.0, 55 °C for 50-60 min, the water absorption ratio and swelling ratio of SPS reach up to 160.5% and 239.1%, respectively. The characterization by infrared spectra, scanning electron microscopy and X-Ray diffraction spectra confirmed that the structure of SPS is similar to that of PS. The degradation experiment in vitro indicated that the degradation effect of PS was better than that of SPS. The whole blood coagulation kinetics experiment showed that SPS could promote the formation of blood clot, and the adsorption experiment of red blood cells in vitro showed that SPS could adsorb red blood cells. The average hemostasis time of SPS in tail amputation 1 cm and liver laceration were 181.03 s and 179.30 s.

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.
