1. Introduction
Biopolymer protein-based films can be a potentially important material in biodegradable plastic packaging. They are an eco-friendly alternative material for use instead of non-degradable synthetic materials. Moreover, they help respond to the concern about the restricted availability of natural resources. Proteins have been widely utilized due to their film-forming ability and nutritional values (Weng et al., 2007). Many waste products from manufacturing can be turned into valueadded inputs to the agricultural industry. Waste protein can be divided into two categories: plant protein and animal protein. One of the utilizable alternatives is biodegradable protein-based film. Many research studies have referred to plant protein-based film fabrication due to the availability of the raw material and the specific characteristics of the film such as uncomplicated fabrication, good appearance and compatible technology. For example, whey protein isolate (WPI) is a byproduct of the manufacture of cheese or casein which is derived from whey. WPI films are flexible, transparent, colorless and odorless films. The reason for the low oxygen permeability is the film's polar nature and the more linear structure of WPI leading to a higher cohesive energy density and a lower free volume (Oses et al., 2009; Kokoszka et al., 2010). Soy protein isolate (SPI) is the waste portion of soy oil manufacturing. SPI film is characterized by smoothness, flexibility, transparency, low solubility and good heat sealability (Denavi et al., 2009; Cho et al., 2010). However, there has been less research on animal protein-based films than for plant protein-based film. The complicated procedure is a barrier to development involving controlling the temperature of the raw material and the several steps in pure chitosan extraction. Nonetheless, animal protein-based films have more advantages than plant protein-based films; for example, chitosan prepared from shrimp processing waste (shells) is not only flexible, transparent, nontoxic and biodegradable but also has antimicrobial properties (Duan and Zhang, 2013). A large amount of FWSP is dissolved in fish mince washing water from the surimi process. This note principally refers to the mince produced when fish flesh is separated from skin and bone in a bone separator. The film is more water resistant than other protein-based films made from soy bean (Ghorpade et al., 1995), rice bran (Gnanasambandam et al., 1997), casein (Frinault et al., 1997) and myofibrillar protein (Cuq et al., 1995) due to the inclusion of the apolar amino acid element (Iwata et al., 2000; Shiku et al., 2004; Bourtoom et al., 2006; Chinabhark et al., 2007; Weng et al., 2007). In the last decade, surimi products have added value to un-utilized fish or low-priced fish and their production has increased annually. Report of the End-of-project meeting of the working party on information collection of economically important species as Surimi raw materials in the Southeast Asian region by the Southeast Asian Fisheries Development Center (SEAFDEC) Training Department at Samut Prakarn, Thailand (SEAFDEC, 2009) demonstrated that the capacity of surimi processing plants in Thailand was approximately 170,200 million t peryear. In particular, in 2008, Thailand exported approximately 65,000 million t of surimi products to Japan. In Japan in 2008, the estimated surimi consumption was 350,000 million t and the world market is expanding into the European Union and Southeast Asia with the major export countries being Thailand, India, Vietnam and Malaysia. Surimi processing involves a first washing and then another two washings, followed by the separation of the skin fat and soluble protein using cold water circulation in a larger tank. The cycling of washing is an important process to improve the gelling properties and produce colorless and odorless surimi. Consequently, the waste water from the surimi process contains a considerable amount of fish water-soluble protein (FWSP). Waste water treatment and the large amount of FWSP sludge could be concentrated using a nanofiltration membrane (Afonso and Borquez, 2002, Yeong et al., 2002; Wibowo et al., 2005; Velazquez et al., 2007). These abundant proteins are separated from the washing water from the surimi process and then mixed into fertilizers and animal feed at low cost. The conversion process of the surimi byproduct into a biodegradable film for food contact material application adds value to the food industry. FWSP compositions include protein, fat, ash and other components at 80.88, 2.94, 6.26 and 9.92 g/100 g, respectively (Bourtoom et al., 2006). The protein contains three amino acid elements: apolar-amino acids i.e. alanine, isoleucine, leucine, methionine, proline, tryptophan and valine; ionized polar amino acids i.e. arginine, asparagine, aspartic acid, glutamine, glutamic acid, histidine and lysine phenylalanine; and non-ionized polar amino acids i.e. cysteine, glycine, serine, threonine and tyrosine. Most of the fish amino acid is glutamic acid lysine acid, aspartic acid and leucine (Shiku et al., 2003; Gercia and Sobral, 2005, Rocha et al., 2013) which are all in the ionized polar amino acids category except for leucine which is in the apolar-amino acid category. These profiles are an important factor in determining the hydrophilic and hydrophobic properties of protein-based film. FWSP film has poor tensile strength and elongation at break (%E) and high water vapor permeability (WVP). These poor characteristics are barriers to any food packaging material application. To overcome these disadvantages requires the influence of plasticizers and filler to increasing the capacity of film fabrication. The inclusion of glycerol, sorbital, sucrose and polyethylene glycol (PEG) decreases the brittleness of protein-based films which is demonstrated by cracking and chipping of the film during film forming and storage (Tanaka, Iwata et al. 2001). Fatty acid as a filler was incorporated not only to increase %E but also to decrease the WVP of the FWSP film (Tanaka, Ishizaki et al. 2001). Moreover, an increase in the Mt concentration resulted in a decrease in the WVP of soy protein isolate/montmorillonite-composite films decrease (Lee and Kim, 2010) and an increase in the glass transition temperature (Tg) of soy protein isolate (Kumar et al., 2010). From the literature review, research on the effect of the Mt concentration on the mechanical, barrier properties and thermal behavior to FWSP films properties is lacking and the FWSP samples were prepared in a scalelaboratory only. The aim of this study was to analyze FWSP-based film made from surimi manufacturing composite to determine with two factors; suitable fatty acid plasticizer and the Mt content; in addition, the film characteristics were investigated. A successful outcome would produce multifunctional film for food packaging applications which would be stronger, more readily available and more biodegradable than currently available synthetic alternatives.
