概括
一种新的喷雾涂层GS-2有效地使可重复使用的食品包装上的大肠杆菌等食物传播细菌失活. 虽然GS-2对细菌有强大作用,但对塑料和纸板表面的真菌和病毒的有效性有限.
科学领域:
- 食品科学 食品科学 食品科学
- 微生物学 微生物学
- 材料科学 材料科学 材料科学
背景情况:
- 欧盟的法规要求到2030年,10%的食品包装必须是可重复使用的,这给美国特种作物出口商带来了食品安全方面的挑战.
- 用可重复使用的包装确保微生物安全对于国际食品贸易至关重要.
研究的目的:
- 为了评估一种新型喷涂剂GS-2 (酸和L-氨酸的氧化碳酸盐) 对可重复使用的食品包装材料的抗菌疗效.
- 评估GS-2对关键的食源性细菌病原体,真菌腐烂生物体和病毒替代物的有效性.
主要方法:
- 对GS-2抗菌药物的有效性进行了测试,对*大肠杆菌*O157:H7,*Listeria monocytogenes*,*Salmonella enterica*,*Aspergillus niger*和小鼠诺病毒进行了测试.
- 测试对烯丁乙,高密度聚乙烯,聚烯和纸板包装材料进行了测试.
- 评估了各种GS-2度,暴露时间和储存条件.
主要成果:
- 在塑料和纸板上,GS-2在禁活*大肠杆菌*O157:H7,*L. monocytogenes*和*S. enterica*方面表现出高效率.
- 在塑料表面上,在60分钟内获得3%的GS-2度,超过5日志CFU/in2减少细菌病原体.
- 对*A. niger*和小鼠诺病毒的疗效有限,所有测试表面的减少≤1日志CFU/in2.
结论:
