Therefore, researchers are introducing innovative techniques in various environments, including ethanol solutions, salt solutions, acidic or alkaline conditions, plasma-activated water (PAW), and hydrogen-infused water (HW), to enhance the efficiency of annealing (ANN) and heat moisture treatment (HMT). The present review discusses these new approaches aimed at improving the performance of ANN and HMT, their potential mechanisms for starch modification, the resulting changes in the functional properties of starch, and their role in various food applications. Additionally, it systematically elucidates the challenges, opportunities, and future directions in this field. Unlike classical water-based ANN or HMT, innovative and sustainable approaches adopted for hydrothermal methods drastically enhance the structural stability, resistance to digestive enzymes, and low-temperature storage stability of starch. However, these changes depend on controlled parameters, such as the concentration of ethanol or salt, pH of the medium, incubation time, moisture level, treatment temperature, and starch properties (e.g., amylose/amylopectin ratio) during treatment. This consolidated report on cutting-edge techniques designed to enhance the effectiveness of hydrothermal modifications seeks to expand the potential applications of ANN and HMT in food-grade products.</div></div>","PeriodicalId":261,"journal":{"name":"Carbohydrate Polymers","volume":"357 ","pages":"Article 123441"},"PeriodicalIF":10.7,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143519141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this issue, we have developed a block Fe<sub>3</sub>O<sub>4</sub>/wood-structural holocellulose hybrids (MW) for removing heavy metal ions from industrial wastewater. By employing chemical pretreatment, solvent-induced self-impregnation, and <em>in-situ</em> deposition, Fe<sub>3</sub>O<sub>4</sub> nanoparticles were attached into the cell's lumen while also embedded within the cell walls, achieving a loading capacity of 35.89 %. The MW exhibited notable magnetic responsiveness. Adsorption experiments were then conducted to evaluate the performance of MW in adsorbing Pb<sup>2+</sup>, and the adsorption mechanism was elucidated based on density functional theory (DFT) calculations. The results demonstrated that MW exhibited high adsorption efficiency for Pb<sup>2+</sup> (537.63 mg/g), This is primarily attributed to the porous structure of MW and the interactions among -COOH, -OH, and Fe<img>O<img> groups within the structure with Pb<sup>2+</sup>. The adsorption process followed the pseudo-second-order kinetic model and the Langmuir isotherm model. After three consecutive reuse cycles, the adsorption capacity remaining at 77.62 % after three cycles. Furthermore, DFT calculations indicated that the composite of Fe<sub>3</sub>O<sub>4</sub> and cellulose could enhance the adsorption energy between Pb<sup>2+</sup> and MW. This indicates that MW offers high adsorption, recyclability, and magnetic control, making it a promising material for wastewater treatment.</div></div>","PeriodicalId":261,"journal":{"name":"Carbohydrate Polymers","volume":"357 ","pages":"Article 123436"},"PeriodicalIF":10.7,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143511242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a feasible approach to tailoring micro-scale morphology in cellulose nanofiber (CNF)-based cryogels by simply adjusting the freeze-templating temperature, resulting in tunable porosity and enhanced performance characteristics. By varying the freeze-templating temperature, we successfully controlled pore size (ranging from 31 to 178 μm), which influenced the mechanical strength (decreasing from 59 to 14 kPa). To explore the effect of micro-scale porosity on the EMI shielding performance, we rendered the CNF cryogels conductivity upon integrating poly(3,4-ethylenedioxythiophene) (PEDOT) with the cryogels framework via chemical vapor polymerization. Our results demonstrate that the larger pore sizes promoted an absorption-dominant EMI shielding mechanism, with an average absorbance (A) of 0.59 across the X-band frequency range. A specific EMI shielding effectiveness (SSE/t) of 4801.25 dB cm<sup>2</sup> g<sup>−1</sup> was achieved for samples with larger porosities, highlighting the decent performance of these engineered cryogels.

Macro-compression shows that cellulose improves the toughness, compression resistance, and Young's moduli of ICE hydrogels, attributed to the synergistic interaction between the cellulose fiber network and ICE due to hydrogen bonding. Pure MFC (363.43 kPa) or NFC (325.75 kPa) alone, compared to a blend of the two with varied contents (261.5–288.5 kPa), displays a more pronounced improvement in the Young's moduli of ICE hydrogels, because homogeneous fiber networks enhance the structural integrity of the system. Micro-indentation reveals that hydrogen bonds between cellulose and ICE weaken the time-dependent deformation of cellulose-composited ICE hydrogel. Mapping of Young's modulus and hardness distribution of the hydrogel suggests that there are three forms of enhancement within cellulose-composited ICE hydrogel: cellulose fiber networks, ICE synergistic network, and synergies between cellulose fiber network and ICE. Creep results highlight that the excellent confinement effect of MFC contributes to creep resistance of cellulose-composited ICE hydrogels. In conclusion, the multiscale characterization unravels the mechanical reinforcing mechanisms of cellulose fibres in ICE hydrogels, which demonstrates the possible strategies for improving the mechanical properties of hydrogels.</div></div>","PeriodicalId":261,"journal":{"name":"Carbohydrate Polymers","volume":"357 ","pages":"Article 123421"},"PeriodicalIF":10.7,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143488275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary question guiding our review was “Why is bacterial cellulose still not used in clinical practice?” Analysis of the literature has shown that the results of <em>in vivo</em> studies often contradict each other. For example, BC caused and did not cause an immune response in an equal number of reviewed articles. Its efficacy in pure form generally does not differ significantly from that of materials already on the market. Conversely, BC may prove to be a valuable material in the long term, not because of its efficacy, but rather because of its affordability and ease of use. Additionally, challenges associated with immune reactions, long-term biocompatibility, and the necessity for standardized experimental protocols must be addressed. We expect that this review will encourage a more thoughtful investigation of BC to bring it into practical medicine.</div></div>","PeriodicalId":261,"journal":{"name":"Carbohydrate Polymers","volume":"357 ","pages":"Article 123427"},"PeriodicalIF":10.7,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143488278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
