BACKGROUND AND OBJECTIVES
Paper and paperboard packaging play an important role in safety and quality of food products. Common bacteria of paper and paperboard food packaging could grow due to specific conditions included humidity, temperature and major nutrition to contaminate the food. The purpose of this research was to investigate numbers and the types of bacteria in the food packaging paperboard.
MATERIALS AND METHODS
The surface and the depth of the each paperboard sample were examined by the dimension of one cm(2) and one gram. The paperboard samples were randomly collected from popular confectionaries and fast food restaurants in Tehran, Iran.
RESULTS
The results indicated the range of 0.2×10(3) to >1.0×10(5) cfu/1g bacterial contamination in paperboard food packaging. Also, most detected bacteria were from spore forming and family Bacillaceae.
CONCLUSION
The bioburden paperboard used for food packaging showed high contamination rate more than standard acceptance level.
背景与目的
纸和纸板包装在食品的安全与质量方面发挥着重要作用。纸和纸板食品包装上的常见细菌可能因湿度、温度和主要营养物质等特定条件而生长，从而污染食品。本研究的目的是调查食品包装纸板中细菌的数量和种类。
材料与方法
每个纸板样品的表面和深度按1平方厘米和1克的尺寸进行检测。纸板样品是从伊朗德黑兰的知名糖果店和快餐店随机收集的。
结果
结果表明，纸板食品包装中的细菌污染范围为0.2×10³至>1.0×10⁵ cfu/1g。此外，检测到的大多数细菌来自芽孢形成菌和芽孢杆菌科。
结论
用于食品包装的纸板生物负荷显示出高于标准验收水平的高污染率。
