Isolation and characterization of a thermally stable collagen preparation from the outer skin of the silver carp Hypophthalmichthys molitrix

Isolation and characterization of collagen from fish waste material- skin, scales and fins of Catla catla and Cirrhinus mrigala

“…The present study suggests that C. mrigala collagen exhibits a higher thermal stability compared to C. catla . However, it is lower than mammalian collagen, and these findings are consistent with the observations of Rodziewicz-Motowidlo et al (2008), who reported that the hydroxyproline and proline contents of silver carp are slightly higher than those of carp. The amino acid contents of both fish types vary among the three tissues selected (skin, scales, and fins).…”

Effect of fish collagen modification on its thermal and rheological properties

“…This relatively high T d of silver carp collagen may be also attributed to the presence of a certain amount of elastin in the sample. Rodziewicz-Motowidło et al [3] reported that the silver carp skin contents at about 75% of collagen, the remaining 25% of the protein includes at about 8% of elastin band and at about 17% of unknown proteins and peptides. DHT-treated collagen with a maximum peak at 80 • C is slightly higher compared with T d of untreated collagen.…”

“…It turns out that physicochemical properties of collagen from fish sources are different from those of land animals. Fish collagen always shows lower contents of hydroxyproline and lower temperature of denaturation (T d ) compared to mammalian collagen [1][2][3]. What is more collagen derived from various fish species has also different physical and chemical properties, which are mainly depends on the living environments.…”

“…What is more collagen derived from various fish species has also different physical and chemical properties, which are mainly depends on the living environments. Interestingly, collagens from fresh water fish origin contain higher level of hydroxyproline and exhibit higher thermal stability than that of marine sources [1,3,4]. The functional properties of collagen is also affected by factors such as aging and the living period of fish samples, the processing steps for raw fish, and the pH and NaCl concentrations during the collagen extraction step [5,6].…”

Northern pike ( Esox lucius ) collagen: Extraction, characterization and potential application

“…There are many fresh water and marine fish. Collagens of fish studied in recent years were from: Rohu (Labeo rohita) [8], Calta (Catla catla) [8], silver carp (Hypophthalmichthys molitrix) [9,10,11], channel catfish (Ictalurus punctaus) [12], red seabream (Pagrus major) [13], Nile tilapia (Oreochromis niloticus) [11,13], golden goatfish (Parupeneus Heptacanthus) [14], brown backed toadfish (Lagocephalus gloveri) [15], Pacific saury (Cololabis saira) [16], deep-sea redfish (Sebastes mentella) [17], brownbanded bamboo Page 3 of 34 A c c e p t e d M a n u s c r i p t 3 shark (Chiloscyllium punctatum) [18], Baltic cod (Gadus morhua) [19] and balloon fish (Diodon holocanthus) [20], silvertip shark (Carcharhinus albimarginatus) [21], grass carp (Ctenopharyngodon idella) [11], seabass (Lates calcarifer) [22], Amur sturgeon (Acipenser schrenckii) [23,24] and other.…”
