Abstract

Utilizing present-day advancements is a well-considered methodology. In such manner, the combination of nanotechnology and food science has prompted the development of numerous capacities in the nutrition section. This study was conducted to evaluate the antimicrobial effect of nano-silver packaging at two refrigerator temperatures (4 and 8oC) in Tilapia to evaluate the total viable count of microorganisms, Escherichia coli, Staphylococcal aureus, and psychrophilic bacteria. Ten grams of washed fish were divided into 5 groups treated with A: 1%: B 3%, C: 5%, D: 7% nano silver coating (E was the control group) and stored for 0, 3, 7, 14 and 30 days. The biochemical analysis of total volatile nitrogen and peroxide composition was investigated, and the best nano silver percentage was 7%. The result of this study demonstrates that the antimicrobial properties of nano silver for various bacterial species are exclusive and we believe that nano-silver packaging improved the quality and shelf life of Nile Tilapia.

挤出法制备纳米银- tio2光催化纳米复合涂层提高尼罗罗非鱼保质期的研究

利用当今的进步是一种经过深思熟虑的方法。通过这种方式，纳米技术和食品科学的结合促进了营养部门众多能力的发展。本研究旨在评估纳米银包装在两种冰箱温度（4℃和8℃）下对罗非鱼的抗菌效果，以评估微生物、大肠杆菌、金黄色葡萄球菌和嗜冷细菌的总活菌数。将10克洗净的鱼分为5组，分别用A:1%、B3%、C:5%、D:7%的纳米银涂层处理（E为对照组），并储存0、3、7、14和30天。对总挥发性氮和过氧化物组成进行了生化分析，最佳纳米银含量为7%。这项研究的结果表明，纳米银对各种细菌的抗菌性能是独一无二的，我们相信纳米银包装提高了尼罗罗非鱼的质量和保质期。
