The concept of food traceability comes from the concern for food safety, especially after the European Union put forward the concept of food safety traceability in 1977 to deal with the problem of mad cow disease, it has been widely used. It records the information of food production, processing, circulation and consumption in detail through the Internet of Things and other technical means, so that the quality and safety of food and its related information can be traced back from the source to the terminal, and it also supports the process of tracing back from the terminal to the source.
As far as food supply is concerned, the significance of food traceability is as follows.
1. Improve safety: Through the traceability system, once a food safety problem occurs, it can quickly locate the source of the problem, recall unqualified products in time, and minimize losses.
2. Enhance consumer confidence: Consumers can directly understand the production and testing information of food by scanning the QR code, thus increasing their trust in food quality.
3. Standardize the production process: The traceability system can urge suppliers to standardize the production process and strengthen the quality inspection of agricultural products, thus improving the management level of the whole supply chain.
Traceability of ingredients is not only conducive to establishing a transparent and reliable food supply chain, but also of great significance to ensuring food safety, improving consumer confidence and promoting the healthy development of agricultural industry.
