重组胶原蛋白检测风波，质谱法应如何助力？

Core Viewpoint - The beauty industry is currently facing a significant controversy regarding the actual content of recombinant collagen, with a focus on the lack of standardized testing methods and criteria, which has led to a trust gap between brands and consumers [2]. Group 1: Industry Controversy - A beauty blogger reported that the recombinant collagen content in a popular product was only 0.0177%, significantly below the national standard of 0.1%, and failed to detect key amino acids like glycine [2]. - The controversy centers not on the technical routes or raw material sources, but on the choice of testing methods and the absence of unified standards, which has hindered the compliant development of the medical beauty industry [2]. Group 2: Regulatory Developments - Since 2022, the National Medical Products Administration (NMPA) has been releasing industry standards for recombinant collagen, including YY/T 1849-2022 and YY/T 1888-2023, to address the heterogeneity of recombinant collagen products [3]. - The introduction of mass spectrometry as a "gold standard" for quality control in recombinant collagen is expected to replace traditional methods that are susceptible to interference from other proteins [3]. Group 3: New Standards Implementation - On August 1, 2022, the NMPA implemented YY/T 1805.3-2022, which provides a high-specificity method for detecting collagen content using LC-MS/MS, addressing the limitations of traditional methods [4]. - A new standard, YY/T 1954-2025, for peptide fingerprint analysis of recombinant collagen is set to be implemented on March 1, 2026, which will enhance quality control and regulatory capabilities in the medical beauty industry [8]. Group 4: Industry Support and Collaboration - The Instrument Information Network is actively monitoring developments in cosmetic testing and promoting collaboration in the field, emphasizing the importance of advancements in testing technology and equipment [13].
