“…2. The modulus of elasticity (G 0 ), modulus of viscosity (G 00 ) and the phase angle (d) all displayed sigmoidal curves during both heating (from 0 to 50 C) and subsequent cooling (from 50 to 0 C) ramp, similar to other reports (Cho et al, 2005;Fernández-Díaz, Montero, & Gómez-Guillén, 2001;Gómez-Guillén et al, 2002). Either ingredient could improve the G 0 and G 00 of hydrogel, the most effective being rutin at 8 mg/g dry gelatin.…”

“…These by-products constitute almost 30% of the total weight of the fish (Gómez-Guillén,Turnay, Fernádez-Díaz, Ulmo, Lizarbe, & Montero, 2002). Recently, skin gelatins from several fish species such as cod and hake (Fernádez-Díaz, Montero, & Gómez-Guillén, 2001),…”

The main purpose of this study was to extract and characterize gelatin from skins of fishes: European perch (Perca fluviatilis) and Volga pikeperch (Sander volgensis), which were collected from the Volga-Caspian basin in Russia. The gelatins were prepared using an alkaline pretreatment. The gelatin yield was in the range of 10.2-13.8% on a wet weight basis, and the gel strength exceeded 184 and 193 g for samples from European perch and Volga pikeperch skins, respectively. The pH values of gelatins were 5.49 and 5.73, melting points were 24.5 and 25.5 o C and protein content was 88.6 and 91.0%, respectively. Water-holding and fat-binding capacities of gelatins were 227-235 and 439-453%, respectively. The gelatins were composed of α-chains, β-chains, and γ-chains. The apparent valine content of the two gelatins was significantly higher than those of gelatins from other fish species. The total apparent proportions of imino acids were 192 and 203 residues/1000 residues. The gelatins from European perch and Volga pikeperch skins had relatively high gel strengths, melting points, water-holding and fat-binding capacities as compared with those of other types of fish and could be recommended as potential replacements for mammalian gelatin in the food industry.

“…As a result, alternative sources, such as fish processing waste in aquaculture industry, including skin, bone, or swim bladders, have received increasing attention for collagen extraction. In recent years, many papers focused on the practical utilization of the by-products of fishes to produce collagen [5,[7][8][9][10]. The soft-shelled turtle (Pelodiscus sinensis) is a commercially important aquatic species in Asian countries including China, Japan and Korea etc., due to its high nutritional and medicinal values.…”

Abstract:The soft-shelled turtle (Pelodiscus sinensis) is a commercially important aquatic species with abundant collagen content and precious nutritious high quality goods. The present study was to optimize the collagen extraction from lung of Pelodiscus sinensis. Single-factor test was employed to investigate the effects of different extraction methods and the major factors that influence the collagen production in enzymatic extraction method on the collagen yield of lung. Optimization of the papain enzymatic extraction parameters was then examined using an orthogonal test design L9 (3 4 ). The optimum extraction conditions were obtained when the extraction temperature, papain enzyme dose, the ratio of solid to solution, and extraction time were 32°C, 4.0mg/ml, 1:35, and 12h, respectively. Under the optimized conditions, the collagen yield was up to 79.29%. The properties of turtle lung collagen were characterized by SDS-PAGE, UV scanning, and amino acid analysis. The results showed that the extracted lung collagen had high imino acid content at 21.8% and contained two α chains, β, and γ-components, belonging to the typical type I collagen. The amphibious aquatic turtle collagen is thought to be a viable novel source for replacement of terrestrial mammals and could provide scientific reference for the development of collagen polypeptide for terrapin animals.
