Description
Technical Field
The invention relates to the technical field of traceability, in particular to an information traceability system for special food supervision.
Background
The special food refers to health food, formula food for special medical application, formula food for infants and the like. Compared with common food, the special food mainly meets the special requirements of special groups such as infants, old people, people suffering from specific diseases and the like, and has special standards. For example, the food safety law clearly implements function catalogue management on special foods, strictly manages raw materials of health-care foods, formulas of infant formula milk powder products and the like, and sets up special requirements on production management, label instruction management and advertising management.
Among them, the health food is claimed to have a health function or to supplement nutrients such as vitamins and minerals. The food is suitable for specific people, has the function of regulating the organism, does not aim at treating diseases, and does not produce any acute, subacute or chronic harm to human bodies.
Due to the fact that health-care food is functional, illegal enterprises often sell the health-care food as a medicine and publicize that the medicine has a treatment effect, or common food is falsely and exaggeratedly publicized to be sold as the health-care food. These illegal activities seriously threaten the health of consumers, and the production operators of health-care food should strictly check themselves to firmly avoid such activities. But the market still has the problems of transitional propaganda, high selling price and the like of various health-care foods. The merchant uses the information asymmetry to make the health food in the aspect of component composition, writes the valuable and expensive natural medicinal materials into a material table, but uses counterfeit products, artificial planting and other inferior-quality products for manufacturing and selling, thereby seriously harming the social and consumer benefits.
The traceable System, i.e. the Traceability System, IS defined by the international organization for standardization (IS 0) as: a system capable of tracking the history and usage or location of goods or activities by means of registered identification codes. Traceability is the ability to trace back the history (e.g. raw material of the product, etc.), application, location or similar product or activity of the product based on or using a recorded identifier (which is unique for each batch of product, i.e. there is a one-to-one correspondence between the identifier and the object to be traced back, and the identifier is stored as a record). "traceable includes 2 pathways: tracking (Tracking) and Tracing (Tracking). Tracking refers to the ability of a product to flow in a forward direction from upstream to downstream of a supply chain, following a particular unit or batch of product travel path. Traceability is the reverse circulation of products from downstream to upstream of the supply chain, i.e. the ability to identify a particular unit or batch of products, i.e. the ability to trace back to an entity by recording identifiers, to make a history, usage and location.
Therefore, a complete traceable anti-counterfeiting system can be constructed and utilized aiming at the existing health-care product market, and the market and the merchant are strictly supervised, so that the legal rights and interests of consumers are constantly guaranteed.
