What is the food traceability code-how did the traceability code come from?

Food traceability code is a two-dimensional code label that records the original production data of raw materials, such as production date, expiration date, country of origin, producer and other information. Source of traceability code: The earliest food safety management system was established and improved by the European Union in response to the problem of 1997 "mad cow disease".

Raw material suppliers carry out batch management when providing raw materials to food production enterprises, input the production data of raw materials such as production date, edible period, country of origin, producer and whether drugs are used in gene combination into two-dimensional codes, print labels with two-dimensional codes, and post them on the packaging boxes to food production enterprises.

When the raw materials of food production enterprises are put into storage, the data collector is used to read the two-dimensional code to obtain the original production data of raw materials. From these data, we can immediately confirm whether the delivered products meet the manufacturer's purchasing standards. Then put the raw materials into storage.

According to the production plan of the day, formulate the formula. According to the production plan, the employees extract the required raw materials from the warehouse, weigh and subcontract them according to the requirements of each batch, and attach labels with two-dimensional codes to the subcontracted raw materials, which contain information such as raw material name, weight, input sequence and raw material number.

This food safety management system is promoted by the government, covering the upstream and downstream of the whole food industry chain, such as food production bases, food processing enterprises and food terminal sales. And share information through special hardware equipment similar to bank ATM system to serve the final consumers.

Extended data:

There are three traceability technologies:

1, RFID technology. Sticking a logo with a chip on the product package can automatically collect and read relevant information when the product is in and out of storage and transported, and the chip can record the flow direction of the product.

2. QR code. Consumers only need to shoot the QR code through the mobile phone with camera, and they can query the relevant information of the goods, and the query record will be saved in the system. Once the product needs to be recalled, they can send text messages directly to consumers to achieve accurate recall.

3, bar code plus product batch information (such as production date, production time, batch number, etc.). ). In this way, the production enterprise basically does not increase the production cost.

The RFID food traceability management system can ensure food safety and traceability, standardize food production, processing, circulation and consumption, issue "electronic identities" to all foods such as rice, flour, oil, meat and dairy products, and establish a food safety database, starting from food planting, breeding, production and processing.

The whole process from farmland to dining table can be traced, including all the information in the process of transportation, packaging, sub-packaging and sales of production bases, processing enterprises and distribution enterprises, which can be found in the database through electronic tags.

Once there is a problem with the quality of food at the consumer end, you can make an online inquiry through the traceability code on the food label to understand all the circulation information such as food production enterprises, food producing areas and specific farmers, and clarify the corresponding legal responsibilities of the accident party. Now this technology has been widely used, except food, in medicine, clothing, electronics, fishing boats and other industries can see the shadow of traceability technology.
