黄天鹅回应“添加人工色素”质疑：重新送检结果待公布

Core Viewpoint - The controversy surrounding the detection of artificial colorants in eggs from the Huang Tian E brand has raised significant public concern, particularly regarding the presence of canthaxanthin, which the company claims is naturally occurring and not artificially added [2][3]. Group 1: Company Response and Actions - Fengji Food Group, the parent company of Huang Tian E, stated that third-party tests did not detect canthaxanthin in their eggs and has committed to re-testing all feed and egg products, with results expected soon [2][4]. - The company has promised to disclose contracts and procurement details related to natural colorants and is exploring the inclusion of egg color standards in industry regulations [2][4]. - In response to the allegations, Fengji Food emphasized that canthaxanthin exists naturally in various foods and that the detected levels (0.399 mg/kg) fall within the range of natural background levels [3][4]. Group 2: Scientific Insights - Professor Zhu Yi from China Agricultural University explained that current detection methods can measure total canthaxanthin but cannot differentiate between natural and synthetic sources due to identical molecular structures [4]. - The professor noted that comprehensive assessments, including farming practices and feed records, are necessary to determine the source of canthaxanthin [4]. Group 3: Regulatory Context - The maximum allowable addition of canthaxanthin in poultry feed is set at 8 mg/kg according to the Ministry of Agriculture and Rural Affairs [5]. - Current national food safety standards do not specify limits for canthaxanthin residues in fresh eggs, indicating a regulatory gap in monitoring this substance [4]. Group 4: Brand Background - Huang Tian E is a brand under Fengji Food Group, which was established in 2018 and has raised significant capital through multiple funding rounds, with investments from notable firms [5]. - The brand promotes its eggs as being produced from hens fed a natural diet, claiming enhanced nutritional value and color due to the presence of natural carotenoids [5].
