Description
Summary:Introduction: Suckermouth catfish are invasive alien species in Malaysia with rapid population propagation, causing negative impacts on the local ecology and economy. Presently, there are no available methods to sufficiently control their populations. The aim of this study is to explore the potential of suckermouth catfish as a source of ingredients for the pharmaceutical industry, which could encourage their utilisation and indirectly control their population. Methods: In this study, acid-soluble collagen extraction was carried out, followed by identification tests, yield calculations, and some basic physical characteristic tests. Results: The extracted collagen was described as off-white and had a strong acetic acid odour. The mean yield of collagen on a wet basis was 10±2.3%, with a hydroxyproline content of 1.6%, while the viscosity and pH of a 20% collagen solution were 0.6±0.25 mPa.s and 5.51±0.1, respectively, comparable to previous studies using various species of fish. Heavy metal contents of the extracted collagen were also found to be within the acceptable limits for use in pharmaceutical and cosmetic applications. Conclusion: This study concludes that the skin of suckermouth catfish is a promising source of collagen for potential industrial applications. However, further studies are needed to improve the yield and purity and establish the physicochemical characteristics, safety, and applications of the extracted collagen. © 2023 UPM Press.
