Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 7
Abstract
This study was conducted i to extract collagen protein from the skin and fin of longtailtuna Thunnustonggol. During fish processing, a great deal of wastes including water and solids were produced and the skin and fin of fish, arising from wastes of aquatic processing, can be considered a replacement of gelatin and collagen sources. Samples used in this study were collected from fish conservation company of Bandarabbas, Iran. In an experiment for collagen extraction from every area of skin and fin was studied and analyzed chemically 3 times. Additionally, the amount of humidity, ash, fat, protein and amino acids were evaluated in these sections. The results showed that in the skin of the tuna has the most percent of humidity, while it didn’t have a significant difference with the humidity of fin (P>0.05). Skin has the most amount of protein (P<0.05). In both samples of skin and fin of the tuna, glycine amino acid was the dominant amino acid and hydroxyprolineamino acid (the main indicator of collagen) in skin showed higher amount in respect to fin (P<0.05).According to achieved results, it can be said that the skin of the tuna fish has more amount of collagen compared to fin (P<0.05). Moreover, electrophoresis model indicated that there isn’t any difference in collagen of skin and fin of the tuna (P>0.05) and both obtained collagen have at least two chains of ? 1 and ? 2.
