“…As far as we know, this is the first study about skin collagen from these species, such as rabbit fish (Chimera monstrosa) or small-spotted catshark (S. canicula). Furthermore, it has been previously reported that shark skin collagen provides an unique material for different purposes as biomaterial, in the feed industry, or cell culture (Nomura et al, 2000). Most collagen properties-such as gelling ability, viscosity, or thermal denaturation-depend on their amino and imino acid composition.…”

Skin collagen of six discarded fish species was analyzed and compared. Acid soluble collagen (ASC) was extracted; a characteristic sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) profile for type I collagen was obtained, except for Chimaera mostrosa. Contents of collagen calculated from HPro (31.85% average) were higher than those determined from ASC extracts (17.75% average), with Galeus spp. being the species with the higher percentage. Amino acid analysis revealed the typical composition of collagen, with very few differences among species. Specific profiles were obtained after protease digestion. Denaturation temperature of ASC correlated well with imino and hydroxyproline contents.Results demonstrate the feasibility of using the obtained collagens in different industrial applications.

“…The original degradation temperature of collagen was only 39 ℃. 29 Thus the grafted collagenAl 2 O 3 /SnO 2 composites possessed good thermal stability. The different changes upon temperature increase indicated the interactions between the grafted collagen-co-nanoparticles and their structures were different from those of the grafted collagen-xerogel, which improved the thermal stability of the grafted collagen.…”

Al 2 O 3 /SnO 2 co-nanoparticles were prepared with a modified sol-gel technique followed by a thermal treatment process. With these co-nanoparticles the grafted collagen-Al 2 O 3 /SnO 2 nanocomposites were obtained using a supersonic dispersion method. X-ray diffraction, FT-IR analysis, transmission electron microscopy, TGA/DTA and infrared emissivity test were performed to characterize the resulting nanoparticles and nanocomposites, respectively. The Al 2 O 3 /SnO 2 co-nanoparticles showed a narrow distribution of size between 20-40 nm and could be uniformly absorbed on the tri-helix scaffolds of the grafted collagen without any aggregation. The nanocomposites possessed better thermal stability and substantially lower infrared emissivity than the grafted collagen and Al 2 O 3 /SnO 2 co-nanoparticles with an increase of degradation temperature from 39 to 210 ℃ and a decrease of infrared emissivity from 0.850 of the grafted collagen and 0.708 of the Al 2 O 3 /SnO 2 co-nanoparticles to 0.424, which provided a potential application of the nanocomposites to areas such as photoelectronics.

“…Their properties were studied by thermal denaturation temperature using differential scanning calorimetry, solubility, and amino acid analysis. Yoshimura et al (2000) and Nomura et al (2000) extracted collagen from the skin of great blue sharks (Prionace glauca) and investigated the physicochemical properties. Also, similar studies were carried out on collagen isolated from the skins of jellyfish and cuttlefish (Nagai et al, , 2001.…”

This study was conducted to investigate the optimal conditions of collagen extraction from scales of yellowfin tuna (Thunnus albacares) using surface response methodology. Four independent variables of NaOH concentration and pretreatment fime in alkali pretreatment and enzyme concentration and treatment time in enzyme hydrolysis were used to predict a model equation for the collagen yield. The determinant coefficient (R 2 ) for the equation was 0.906. The values of the independent variables for the maximum yield were 0.32 N NaOH, 16.38 h alkali pretreatment time, 0.18% enzyme concentration, and 31.02 h enzyme treatment time. In the physicochemical properties of tuna scale collagen, sodium dodecyl sulfate-polyacrylamide gel electrophoresis of tuna scale collagen showed the same migration distances as that of calf skin collagen. The amide A, I, II, and III regions of tuna scale collagen in Fourier transform infrared measurements were shown in the peaks of 3,414 cm -1 , 1,645 cm -1 , 1,553 cm -1 , and 1,247 cm -1 , respectively. The amount of imino acids in tuna scale collagen was 18.97% and the collagen denaturation temperature was 33°C. The collagen solubility as a function of NaCl concentration decreased to 4% NaCl (w/v) and the collagen solubility as a function of pH was high at pH 2-4 and sharply decreased from pH 4 to pH 7. Viscosity of the collagen solution decreased continuously until 30°C and this decreasing rate slowed in the temperature range of 35-50°C.
