“…Fish gelatins exhibit good film-forming properties, yielding transparent, nearly colourless and highly extensible films (Avena-Bustillos et al, 2006;Carvalho et al, 2008;Gómez-Estaca, Montero, Fernández-Martín, & Gómez-Guillén, 2009;Jongjareonrak, Benjakul, Visessanguan, Prodpran, & Tanaka, 2006;Zhang, Wang, Herring, & Oh, 2007). Furthermore, enriching gelatin films with antioxidants and/or antimicrobial substances will extend the functional properties of these biodegradable films and provide an active packaging biomaterial.…”

a b s t r a c tIn order to provide gelatin films with antioxidant capacity, two sulphur-free water-insoluble lignin powders (L 1000 and L 2400 ) were blended with a commercial fish-skin gelatin from warm water species at a rate of 85% gelatin: 15% lignin (w/w) (GeL 1000 and GeL 2400 ), using a mixture of glycerol and sorbitol as plasticizers. The water soluble fractions of GeL 1000 and GeL 2400 films were 39.38 AE 1.73% and 46.52 AE 1.66% respectively, rendering radical scavenging capacity (2,2 0 -azino-bis(3-ethylbenzothiazoline-6-sulphonic acid, ABTS assay)) of 27.82 AE 2.19 and 15.31 AE 0.88 mg vitamin C equivalents/g film, and ferric ion reducing ability (FRAP assay) of 258.97 AE 8.83 and 180.20 AE 5.71 mmol Fe 2þ equivalents/g film, respectively. Dynamic oscillatory test on film-forming solutions and Attenuated Total Reflectance (ATR)-FTIR spectroscopy study on films revealed strong lignin-induced protein conformational changes, producing a noticeable plasticizing effect on composite films, as deduced from the study of mechanical (traction and puncture tests) and thermal properties (Differential Scanning Calorimetry, DSC). The gelatin films lose their typical transparent and colourless appearance by blending with lignin; however, the resulting composite films gained in light barrier properties, which could be of interest in certain food applications for preventing ultraviolet-induced lipid oxidation. Lignin proved to be an efficient antioxidant at non-cytotoxic concentrations, however, no remarkable antimicrobial capacity was found.

“…Gelatin was isolated from the skins of different fresh water species, including catfi sh (Yang et al 2007 ;Yang and Wang 2009 ), silver carp (Boran and Regenstein 2009 ), grass carp ( Catenopharyngodon idella ) (Ladislaus et al 2007 ); and marine fi shes such as sharks (Hamada 1990 ), dogfi sh ( Squalus suckleyi ) (Geiger et al 1962 ), yellowfi n tuna ( Thunnus albacares ) (Andre et al 2003 ;Cho et al 2005 ;Gómez-Estaca et al 2009b ), megrim ( Lepidorhombus boscii ) (Montero and GomezGuillen 2000 ), cod (Gudmundsson and Hafsteinsson 1997 ), Atlantic salmon (Salmo salar) (Arnesen and Gildberg 2007 ), Chum salmon ( Oncorhynchus keta ) (Zhang et al 2011 ), greater Lizardfi sh ( Saurida tumbil ) (Taheri et al 2009 ), grouper (Rahman and Al-Mahrouqi 2009 ), pollock (Bower et al 2010 ), bigeye snapper and brownstripe red snapper (Jongjareonrak et al 2006 ), sin croaker ( Johnius dussumieri ) and shortfi n scad ( Decapterus macrosoma ) (Cheow et al 2007 ).

There are various reasons for considering the marine gelatin as an alternative to the terrestrian mammals' gelatin (bovine and pigs). Among them is the risk of transmission of infections illnesses, like spongiform encephalopathy, in bovine gelatin. From a social-cultural approach, some cultures reject animal gelatine due to their religious beliefs. One advantage of marine gelatin is that it has no risk associated with Bovine Spongiform Encephalopathy. In addition, it is considered as Kosher and Halal. This chapter is dedicated to methods of gelatin isolation from marine fi sh skins, scales, cartilage and bones. A variety of practical applications for fi sh gelatins in the form of gels, fi lms and composite materials is discussed.
