Outline
To investigate the adulteration status of commercial cooked beef products and analyze the characteristics of undeclared animal-derived components.
A total of 133 samples of commercial cooked beef products were collected. Based on the SN/T 2051—2008 Determination of bovine, ovine, porcine-derived materials in food, cosmetic and feed-Real-time PCR method and GB/T 38164—2019 Identification of animal ingredient from common livestock and poultry-Real-time PCR, real-time fluorescent polymerase chain reaction was employed to detect 5 kinds of animal-derived components, namely cattle, sheep, pig, chicken and duck, thereby establishing the profiles of undeclared animal-derived components.
Among the 133 samples, 16 were detected with undeclared animal-derived components, resulting in the adulteration rate of 12.03%. The adulteration rate in cooked dried meat products from large and medium-sized supermarkets was significantly higher than that from small supermarkets and other sales venues. Among the detected undeclared animal-derived components, chicken-derived components had the highest detection rate (68.75%), followed by pork-derived (25.00%) and duck-derived components (18.75%), while sheep-derived components showed the lowest detection rate (12.50%).The profile of undeclared animal-derived components comprised 6 types, with the single adulteration of chicken-derived components being the most prevalent (62.50%).
The inspected commercial cooked beef products on the market have some adulteration issues, mainly involving the addition of chicken-derived components. Regulatory authorities should establish a regular sampling inspection mechanism for beef products and promote the full coverage of the traceability system to ensure product quality and safety.
