蜂产品,例如,壳聚糖和蜂胶(Pro),在包括食品生物保存在内的许多学科中都具有非凡的重要性。鱼肉极易变质,尤其是cat鱼(Clariasgariepinus)产品。目前的工作涉及提取蜜蜂壳聚糖纳米颗粒(BCht),Pro,亲介导的SeNPs及其复合物,评估它们作为潜在的抗菌和防腐纳米化合物,用于保存cat鱼片并提高其质量。BCht是从蜜蜂(Apismellifera)尸体中提取的,平均粒径为151.9nm。Pro用于SeNPs的生物合成,其平均直径为11.2nm。整个化合物/复合材料对大肠杆菌表现出强大的抗菌作用,金黄色葡萄球菌和鼠伤寒沙门氏菌,金黄色葡萄球菌的耐药性最高。BCht/Pro/SeNP对所有细菌菌株都是最有力的。由生产的化合物/复合材料(BCht,Pro,Pro/SeNPs,Pro/BCht和BCht/Pro/SeNPs)在冷藏7天期间保存cat鱼片的效率更高。微生物(总数,嗜冷细菌,酵母和霉菌),腐败化学参数(TVB-N,TBARS)和感官属性(外观,气味,颜色,ECs处理的鱼片的整体质量)表明纳米复合材料保护鱼类免受微生物生长的效率,化学腐败指标的进步和保持处理过的储存鱼片的感官质量。保持整个鱼片质量的最有效的纳米复合材料是BCht/Pro/SeNP。基于BNCt的EC,Pro/SeNPs及其纳米复合材料可以在各种海产品的生物保存中得到认可。
Bee products, e.g., chitosan and propolis (Pro), have extraordinary importance in many disciplines including food biopreservation. Fish meat is highly susceptible to vast spoilage, especially catfish (Clarias gariepinus) products. The current work involved the extraction of bees\' chitosan nanoparticles (BCht), Pro, Pro-mediated SeNPs and their composites, to evaluate them as potential antimicrobial and preservative nano-compounds, for the preservation of catfish fillets and augment their quality. BCht was extracted from bees (Apis mellifera) corpses and had a 151.9 nm mean particle diameter. The Pro was used for biosynthesis of SeNPs, which had 11.2 nm mean diameters. The entire compounds/composites exhibited powerful antibacterial acts against Escherichia coli, Staphylococcus aureus and Salmonella typhimurium, where S aureus had the uppermost resistance. BCht/Pro/SeNPs were the most forceful toward all bacterial strains. The constructed edible coatings (ECs) from produced compounds/composites (BCht, Pro, Pro/SeNPs, Pro/BCht and BCht/Pro/SeNPs) had elevated efficiency for preserving catfish fillets during cold storages for 7 days. The microbiological (total counts, psychrophilic bacteria, yeast and molds), spoilage chemical parameters (TVB-N, TBARS) and sensorial attributes (appearance, odor, color, overall quality) of ECs-treated fillets indicated the nanocomposite\'s efficiency for protecting the fish from microbial growth, the progress of chemical spoilage indicators and maintaining the sensorial quality of treated stored fillets. The most effective nanocomposite for maintaining the entire fillet\'s quality was the BCht/Pro/SeNP. The based ECs on BNCt, Pro/SeNPs and their nanocomposites could be endorsed for prospective employment in the biopreservation of various seafoods.
