摘要

Collagen, a key structural protein, is crucial for tissues, such as skin, bones, tendons, and cartilage. Due to its strength and flexibility, it is highly valuable for materials development. Collagen can be sourced from fish waste, which constitutes 65% of the 70 million tons of processed fish annually. In the Yucatan Peninsula, Haemulon plumierii (Coro Coro) is commonly caught in large quantities, although its commercial value is low. Its meat is of high quality, and collagen can be extracted from its skin using various methods, including conventional extraction (CM), lactic acid fermentation (FM), and enzymatic extraction (EM). This study compared these methods, with collagen yields of 0.57 ± 0.03 for CM, 2.19 ± 0.17 for FM, and 4.22 ± 0.35 for EM. Protein profiling confirmed collagen presence, with EE showing superior quality, exhibiting gamma, beta, and alpha chains. EM-derived collagen holds potential for medical and food biomaterial applications.
