Abstract: The present invention refers to a composition comprising a solution which in turn comprises an amino acidic chain gelatin polymer derived from natural sources of cold-adapted marine species, at a concentration from 1% to 20% (w/v), which optionally further comprises a polymerizing initiator such as a photoinitiator, and is chemically functionalized to become reactive to polymerization or crosslinking in presence of free radicals. This composition is especially useful for 3D printing, extrusion systems (additive fabrication), spray systems, casting, micro- and nano fibers fabrication systems (electrospinning, solution blow spinning) or microfluidics.

Abstract: The present document describes a composition and pharmaceutical composition comprising gelatin derived from a cold-adapted aquatic species, chitosan, agarose and glycerol. Further, the present document discusses a process for manufacturing a biomaterial which comprises gelatin derived from a cold-adapted aquatic species, chitosan, agarose and glycerol. The biomaterial obtained or obtainable through the process is also described. Also, the present document describes a kit which comprises: gelatin derived from a cold-adapted aquatic species, chitosan, agarose, and glycerol. Lastly, the use of the composition, pharmaceutical composition, biomaterial or kit for the production of scaffolds, dressings, beads, engineered tissues, devices or micro-devices suitable for therapeutic or diagnostic purposes or the use of the composition, biomaterial or kit for tissue engineering are also discussed.

Abstract: System for determining gas permeability (O2, CO2, N2, air) in films, especially edible films, wherein the system comprises a receptacle (A) containing a liquid of low solubility to the gas that is not reactive to it or dissolves the film; gas bubble generating means comprising a cylinder that contains the gas (G); a driver (E) that regulates gas flow and drives the syringe plunger (F); an image acquisition system comprising a high resolution camera (C); lighting (B) that uses a lighting means; and image processing means, preferably a computer program (D); and a method that comprises placing the liquid in an receptacle and letting the gas (G) flow, generating uniform bubbles in the liquid, and placing the film over the liquid; taking photographs or images for a determined time range and frequency and with an auxiliary lighting means; processing photographs or images in an image processing means, and determining variation in the bubbles volume at different times, wherein the bubble volume is determined based on
