被华熙生物暗指“伪科学”！巨子生物回应：不作评价

Core Viewpoint - Huaxi Biological asserts that claims exempt from scientific verification are inherently pseudoscientific, emphasizing the necessity of measurable and verifiable scientific methods in the industry [1][2]. Group 1: Huaxi Biological's Position - Huaxi Biological argues that the absence of standardized testing methods does not negate the existence of scientific methods for validation, using their product "Runbaiyan" as an example of verifiable testing results for recombinant collagen [2][5]. - The company highlights the use of High-Performance Liquid Chromatography-High-Resolution Mass Spectrometry (HPLC-HRMS) as a reliable method to accurately measure recombinant collagen content, claiming it effectively avoids complex matrix interference [5][12]. Group 2: Response from Juzhi Biological - Juzhi Biological acknowledged the limitations of their existing quality standards and testing methods in a statement, indicating a need for continuous optimization to meet industry advancements [6][9]. - The company plans to collaborate with research institutions to enhance the qualitative and quantitative detection methods for recombinant collagen in cosmetics, aiming for greater transparency and industry standardization [9][10]. Group 3: Testing Method Controversy - The debate over testing methods arose when beauty blogger Dazui Doctor (Hao Yu) questioned the recombinant collagen content in a product, using a high-precision HPLC amino acid quantification method, which Juzhi Biological claimed was not included in industry standards [10][11]. - Experts noted that both HPLC amino acid quantification and HPLC-HRMS methods have their unique applications and challenges, particularly in detecting low concentrations of collagen in complex cosmetic formulations [12][13].
