“…To overcome these issues, nonvolatile (at the processing temperature) plasticizers such as polyols (glycerol, sorbitol, glycol, etc. ) (Da Róz et al 2006;Enrione et al 2010;Forssell et al 1997;Gaudin et al 1999;Kirby et al 1993;Lin and Tung 2009;Liu et al 2011d;Lourdin et al 1997;Mathew and Dufresne 2002a;Nashed et al 2003;Qiao et al 2011;RodriguezGonzalez et al 2004;Shi et al 2007a, b;Smits et al 2003;Tan et al 2004a, b;van Soest et al 1994van Soest et al , 1996Wang et al 2009a;Yan et al 2012;Zhang et al 2008), nitrogen-based compounds (urea, ammonium derived, amines, etc.) (Dai et al 2009b(Dai et al , 2010aMa and Yu 2004a, b, c;Ma et al 2004Ma et al , 2005Ma et al , 2006Shogren et al 1992;Tung et al 2011;Wang et al 2009a;Yang et al 2006aYang et al , b, c, 2007Zhang et al 2008;Zheng et al 2009b), or citric acid (Shi et al 2007b;Wang et al 2007;Yu et al 2005a) are utilized.…”

“…For example, hydroxypropylated starch displays improved processability (lower viscosity) and mechanical properties Lafargue et al 2007;Vorwerg et al 2004); and acetylated starches with a degree of substitution of 2-3 are water insoluble and have good mechanical properties (Fringant et al 1996(Fringant et al , 1998Jarowenko 1986;Mbougueng et al 2012;Volkert et al 2010;Yan et al 2012;Zamudio-Flores et al2010). However, it should be noted that chemical modification often decreases the polysaccharide molar mass, potentially leading to materials with less mechanical strength, and also the toxic chemical residues may modify the biodegradability and negatively impact the life-cycle assessment (LCA) of the final products.…”

Starch as a biopolymer directly extracted from nature has received much attention in recent years due to its strong advantages such as low cost, wide availability, renewability, and total compostability without toxic residues. Starch-based materials always display properties that are less satisfactory than those of traditional polymer materials, which can be ascribed to the inherent characteristics of starch. To make such materials to be truly competitive and to widen its applications, the development of starch-based nano-biocomposites could be a promising solution. This chapter provides the fundamental knowledge related to starch-based nano-biocomposites as well as the most recent developments in this area. Various types of nanofillers that have been used with plasticized starch are discussed such as montmorillonite, cellulose nanowhiskers, and starch nanoparticles. The preparation strategies for starch-based nano-biocomposites with these types of nanofillers and the corresponding dispersion state and related properties are also largely discussed.

“…Figure 9a, b and c exhibited that transmittance decreased with the level of chitosan however; it increased with glycerol and temperature. Yan et al (2012) documented that the films containing 35 % glycerol had the highest light transmittance rate, whereas lowest with 30 % glycerol level. Bangyekan et al (2006) …”

Development of chitosan based edible films: process optimization using response surface methodology

2014

View full text Add to dashboard Cite

Three-factors Box-Behnken design of response surface methodology (RSM) was used to optimize chitosan level (1.5, 2.0, 2.5 %w/v), glycerol level (0.5, 0.75, 1.0 %w/v) and drying temperature (35, 40, 45°C) for the development of chitosan based edible films. The optimization was done on the basis of different responses viz. thickness, moisture, solubility, colour profile (L*, a*, b* value), penetrability, density, transmittance and water vapor transmission rate (WVTR). The linear effect of chitosan was significant (p<0.05) on all the responses. However, density was only significantly (p<0.05) affected by glycerol in a negative linear fashion. Drying temperature also significantly (p<0.05) affected thickness, penetrability, transmittance and WVTR in linear terms. The quadratic regression coefficient of chitosan showed a significant effect (p<0.05) on moisture, solubility and WVTR; glycerol level on moisture, L* value and transmittance; and drying temperature on a* value, penetrability, transmittance and WVTR. The effect of interaction of glycerol x temperature as well as chitosan x temperature was also significant (p<0.05) on a* value and WVTR of edible films. The optimized conditions were: 2.0 % w/v chitosan level, 0.75 % w/v glycerol level and drying temperature 40°C at a constant time of 48 h. All the response variables were in favourable range including thickness; 108.59 mμ, penetrability; 16.41 N, transmittance; 75.60 %, WVTR; 0.00174 g/m 2 -t for the optimized edible film. Results concluded that edible films with desirable bio-mechanical properties can be successfully developed and effectively utilized in the food packaging industry.

“…Starch-based films have good mechanical properties with comparable tensile strength and elongation at break at ambient humidity compared to films made with synthetic polymers (Lourdin, Coignard, Bizot, & Colonna, 1997;Parra, Tadini, Ponce, & Lugão, 2004;Yan, Hou, Guo, & Dong, 2012). Among various starches from different sources, tapioca starch exhibits a good film-forming property (Parra et al, 2004) and produces transparent films (Moorthy, 2004).…”
