Biochemical Characterization of Collagen Extracted from the Swim Bladder of Catfish (Bagre panamensis)

Abstract

In the present investigation, the extraction and subsequent characterization of the collagen in the swim bladder of catfish was developed, for which a total of twelve experimental units were analyzed, distributed in three samples with four repetitions per analysis distributed under a completely randomized design with a 0,05% of significance, the size of the experimental unit 200g of lyophilized collagen. Protein, minerals, water, pH, hydroxyproline were then quantified in addition to the microbiological assays. The results obtained correspond to 76.86% of protein, 9.02% of humidity, 14.12% of ash, while for pH 4.55, hydroxyproline 44,08% and ausence of UFC/g were reported. It is determined that it can be used in food formulations to improve the texture due to its hydroxyproline content.
