Abstract

The economy of freshwater fish in aquaculture production is reported to be increasing throughout the year in Malaysia and as much as 33% of the freshwater fish production has been contributed by Talapia fish, thus, this will increase the amount of fish waste that can be useful product. Tilapia fish can be a good resource of gelatin to replace any other gelatin that available in market nowadays, and also, HALAL issues would be one of the major problems anymore. This research was carried out to observe the properties and characterization of fish gelatin based film with different type of plasticizers and to identify of effect of different types of plasticizers based on its mechanical and thermal properties of fish gelatin based film. As many as four different types of plasticizer with the same concentration were added into fish gelatin based film, they are, Glycerol, sorbitol, Glycerol + sorbitol and Diethylene Glycol. Tensile test was held to study the mechanical properties of the plasticized films and tensile strength and it elongation at break were observed. While Differential Scanning Calorimetry test was held to determine the glass temperature state of the plasticized film where glass temperature can determine the temperature at which the binding force of intermolecular structure of gelatin film to be in relaxed of free state in order to allow large-scale of molecular movements, as the movement of molecular increase, the lower the glass temperature of the plasticized films. The Thermogravimetric analysis test was held to observe the weight loss of the plasticized films in the function of temperature and Fourier Transform Infrared Spectroscopy (FTIR) test proved that the different types of plasticizer that was added in the fish gelatin based film, brings out different type of molecular bonding to be stretched and plays different functional roles. These experiments confirmed that different type of plasticizer that was added into fish gelatin based films, gives out different kind of mechanical, physical and thermal properties of the films and to concluded that, fish waste possess the potential to be an alternative gelatin source for variety uses in many fields, also, the behaviour of the plasticized films was explained in terms of molecular weight of plasticizers which demonstrated that the studied properties could be considered as functions of the number of molecules of plasticizers in the films. Finally, the main findings of this research is to prove that fish gelatin based film can be another way to substitute to bio-based films such as starch based films that have been widely used nowadays, as in results, fish gelatin based films shows a positive number based on their mechanical properties rather that starch based films, yet again both of them can be used functionally based on application that will be applied through them.
