Food contact materials and products may affect the smell, taste and color of food in the process of contact with food, and may release a certain amount of toxic chemical components such as heavy metals and toxic additives, which will migrate to food and be ingested by the human body, endangering human health. In recent years, food safety problems caused by food contact materials have occurred frequently, and countries such as China, the European Union and the United States have paid more and more attention to the safety of food contact materials, and have successively introduced corresponding laws and regulations. Today, Hengxiang Testing Xiaobian will come to tell you about some items included in food contact materials/food packaging testing.
