The resulting film exhibits ammonia-sensitive color-changing properties, antibacterial activity, and excellent biodegradability. The effects of Cu-MOF incorporation on the structural, physical, and functional properties of the CS/Gel films were systematically evaluated. Results demonstrated that the Cu-MOF was uniformly distributed within the CS/Gel matrix, significantly enhancing the mechanical properties (tensile strength increased by 68.49%), oxygen/water vapor barrier properties, and UV-blocking capability of the films. Notably, the CS/Gel@Cu-MOF films exhibited excellent antibacterial performance, with sterilization rates of 94.2% against <em>Escherichia coli</em> and 99.6% against <em>Staphylococcus aureus</em>. Additionally, the films showed good biocompatibility, biodegradability, and a sensitive color response to ammonia. The films were successfully used to monitor shrimp freshness through color change, transitioning from light green to brown as spoilage occurred.

The results showed that ultrasonication caused uniform hydrophilic BSA and MA particle formation in optimal conditions.

Pre-soaked whole buckwheat (BW) grains were subjected to HHP treatment under different processing conditions: two pressure levels (300–600 MPa) and three holding times (0-5-15 min) to evaluate the techno-functional and nutritional response of the resulting flours. Significant (p &lt; 0.05) increases in water absorption capacity and swelling capacity were observed in the flours resulting from longer treatment times (5–15 min) and the highest-pressure level (600 MPa). Higher thermal stability was also observed in the pasting profiles obtained for these flours. Flours resulting from HHP treatments at 600 MPa for 15 min also showed higher antioxidant capacity (DPPH and ORAC). The resulting flour from these processing conditions was used at different concentrations (15, 30, 50, and 70 %) in a GF bread formulation. An increase in the elastic modulus values of the doughs, the specific volume of the resulting bread and a reduction in the crumb firmness were observed in the formulations containing the BW-modified flour compared to the counterparts made with a native flour. Therefore, it can be concluded that the HHP treatment of whole buckwheat grains represents an interesting alternative for the development of ingredients with suitable technological and nutritional properties for gluten-free bakery formulations.</div></div>","PeriodicalId":320,"journal":{"name":"Food Hydrocolloids","volume":"159 ","pages":"Article 110698"},"PeriodicalIF":11.0,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142444963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
