An electronic device for assessing a state of a product likely to transform by emission of volatile organic compounds includes olfactory sensors, designed to provide signals representative of a presence of volatile organic compounds in the ambient air close to the product, and a processor for processing the provided signals to obtain a signature representative of the state of the product. It further includes a memory for storing a reference signature, representative of an exposure of the olfactory sensors to a reference humid environment in which the product is not present, and a computer which computes a similarity value for similarity between the signature representative of the state of the product and the reference signature, to provide a product transformation index value from the computed similarity value.

A hybridoma cell line of secreting cyproheptadine monoclonal antibodies with a preservation number of CGMCC No. 14699 belongs to the field of food safety immunological detection. BALB/c mice are immunized through one time immunization with complete freund's adjuvant, three times of booster immunization with incomplete freund's adjuvant and one time of rush immunization with cyproheptadine complete antigen without adjuvant; the spleen cells from BALB/C mice immunized with high potency and low value of IC50 are fused with murine myeloma cells; and then the hybridoma cell line is obtained through indirect competitive ELISA screening and three sub-clones. The monoclonal antibody secreted by this cell line has good specificity and detection sensitivity to cyproheptadine (value of IC50 is 0.37 ng/ml), being suitable for detection of cyproheptadine in food.

Disclosed is a method for realizing batch-based traceability for pork based on a QR code. Based on the QR code, user information is added to a web address carried by the QR code to realize the traceability for the pork. The method includes: 1) registering basic information of pigs in breeding and brokering processes; 2) printing an initial traceability QR code of a carcass in a slaughtering process; 3) adding user information to the initial traceability QR code in a selling process, and updating the user information to the traceability system; and 4) scanning the traceability QR code to recall data of the traceability system in a catering process to achieve transparent information. The pork and pork products are traced from production process to the selling process.
