With the increasing awareness of food safety, the safety of food contact materials (Food-safe materials) has been paid more and more attention. Food packaging, tableware, kitchenware, food processing machinery and other items that are in direct contact with food directly affect the quality of food and human health. Therefore, ensuring that food contact materials meet the relevant standards has become the focus of attention of manufacturers, regulators and consumers.

1. What is a Food-safe material?

Food-safe materials refer to materials that will not release harmful substances, affect the taste or color of food and do no harm to human health when in direct contact with food under normal use conditions. Common food contact materials include plastic, glass, ceramics, metal, rubber and paper.

Second, the Food-safe materials must meet the standards

Different countries and regions have formulated strict standards and regulations for food contact materials to ensure their safety. The following are some major international and regional standards:

1. EU standards: The EU's supervision of food contact materials is mainly based on the EU Framework Regulation (Regulation EC No 1935/2004), and specific regulations have been formulated for different materials such as plastics (Regulation EU No 10/2011), ceramics, metals and rubber.

2. US FDA standard: The management of food contact materials by the US Food and Drug Administration (FDA) is mainly based on the Federal Food, Drug and Cosmetic Act (FD&C Act), which requires that materials shall not release toxic substances during use and shall not affect the safety and sensory characteristics of food.

3. Chinese National Standard (GB): China has formulated the National Standard for Food Safety-General Safety Requirements for Food Contact Materials and Products (GB 4806 series), which covers a variety of materials such as plastics, metals, ceramics and glass, and defines key safety indicators such as migration, heavy metal content and microbial indicators.

In addition, Codex Alimentarius has also put forward relevant suggestions on food contact materials, providing reference for countries to formulate laws and regulations.

Third, how to ensure the compliance of Food-safe materials

1. Selection of raw materials: Choosing raw materials that meet food safety standards is the first step to ensure material safety. Raw materials containing toxic heavy metals, plasticizers and other harmful substances should be avoided.

2. Production process control: pollution should be avoided in the manufacturing process, and the types and dosage of additives should be strictly controlled to ensure the stable and controllable production process.

3. Product testing and certification: Enterprises should regularly carry out physical, chemical and microbial testing on products to ensure that they meet the relevant indexes such as migration and dissolution. If necessary, third-party certification should be obtained, such as CE certification of EU, FDA registration, ISO 22000 food safety management system certification, etc.

4. Labeling and instructions for use: The product shall be marked with information such as applicable temperature range, usage mode, whether it is suitable for microwave oven or dishwasher, etc. to help consumers use it correctly and prevent potential safety hazards caused by misuse.

Fourth, the future development trend

With the popularization of environmental protection and health concepts, food-grade materials are developing in the direction of being degradable, renewable, non-toxic and harmless. Biobased plastics and degradable packaging materials have gradually become the new favorites of the industry. At the same time, the supervision of food contact materials in various countries will become increasingly strict, which will promote enterprises to continuously improve product quality and safety.

Food-safe materials are not only an important guarantee for food safety, but also the key for manufacturers to win market trust. Under the background of globalization, enterprises must deeply understand the standards of various countries, strictly control the safety of materials, and ensure the compliance of products from the source to the terminal. Only in this way can "safety on the tip of the tongue" be truly realized.
