Physical, Mechanical, and Morphological Performances of Arrowroot (Maranta arundinacea) Fiber Reinforced Arrowroot Starch Biopolymer Composites

Abstract

This research is driven by stringent environmental legislation requiring the consumption and use of environmentally friendly materials. In this context, this paper is concerned with the development and characterization of thermoplastic arrowroot starch (TPAS) based biocomposite films by incorporating arrowroot fiber (AF) (0−10%) into a glycerol plasticized matrix by using the solution casting method. Developed TPAS/AF composite films were investigated, such as physical, morphological (FESEM), tensile, and tear strength characteristics. The tensile and tear strengths of TPAS/AF composites were increased significantly from 4.77 to 15.22 MPa and 0.87 to 1.28 MPa, respectively, as compared to the control TPAS films, which were 2.42 MPa and 0.83 MPa, respectively, while elongation was significantly decreased from 25.57 to 6.21% compared to control TPAS film, which was 46.62%. The findings revealed that after the fiber was reinforced, the mechanical properties were enhanced, and the optimum filler content was 10%. Regardless of fiber loadings, the results of water absorption testing revealed that the composite films immersed in seawater and rainwater absorbed more water than distilled water. Overall, the results of this research focus on providing information on biopolymer composite film and revealing the great potential it has for the food packaging industry.

Dragon Fruit Peel Extract Enriched-Biocomposite Wrapping Film: Characterization and Application on Coconut Milk Candy

“…Thus, a more porous, coarser, and thicker structure of the 2% DPE-incorporated film was observed compared to the control (0% DPE) biopolymer film. Similar findings were reported in studies on the contribution of fiber addition to an increase in the thickness of starch-based films [ 57 , 58 , 59 ].…”

“…The interactions through the non-covalent hydrogen bonding of the polysaccharide chain of rice starch-pectin biocomposite matrix with the polyphenols in the dragon fruit peel extract possibly led to the forming of the complex inclusion (V-type amylose) [ 54 , 55 , 56 ]. This helix structure of the polyphenols and polysaccharide chains of the starch-pectin biopolymer matrix limited the movement of the polysaccharide chain [ 57 ]. Thus, a more porous, coarser, and thicker structure of the 2% DPE-incorporated film was observed compared to the control (0% DPE) biopolymer film.…”

Morphology and selected properties of kenaf fiber/cornhusk reinforced corn starch hybrid biocomposites

“…Fiber addition had a similar effect on the thicknesses and densities of biocomposite films, according to Edhirej et al [14] who studies cassava bagasse reinforced thermoplastic cassava starch, sugar palm starch biocomposite films [32], seaweed/sugar palm fiber reinforced ther-moplastic sugar palm starch/agar hybrid composites [33], thermoplastic films based on Dioscorea hispida starch [34] and arrowroot fiber reinforced arrowroot starch biopolymer composites [35]. Nonetheless, the lower densities of composite samples made them desirable materials, particularly for applications that demand compactness and ease of use.…”

“…Composites made of natural fibers are less resistant to moisture because hydroxyl and polar groups are moisture-absorbers [18,25,35,40,41]. Therefore, the influence of the water absorption rate on the CS-K/CH hybrid composites properties was investigated.…”

Impact of Guar Gum and Locust Bean Gum Addition on the Pasting, Rheological Properties, and Freeze–Thaw Stability of Rice Starch Gel

“…It has been reported that the different synergistic effects of starch and hydrocolloids could be related to the physicochemical differences of hydrocolloids such as solubility [ 21 , 22 , 23 ], intrinsic viscosity [ 24 ], extended conformation [ 25 , 26 ], antioxidant potential [ 27 , 28 ], hydrogen bonding capacity [ 29 ], flexibility [ 30 ], and temperature of gel formation [ 24 , 31 , 32 ]. The diversity of hydrocolloid molecular structures, especially for the differences in the side chain, usually contributes to the variations in physicochemical properties [ 33 ].…”
