Effects of high-pressure homogenization on the properties of starch-plasticizer dispersions and their films

Effect of Plasticizer Type and Concentration on Tensile, Thermal and Barrier Properties of Biodegradable Films Based on Sugar Palm (Arenga pinnata) Starch

“…The tensile strength values of plasticized SPS films were higher than the reported values for films of corn starch with glycerol and stearic acid [69], corn starch with glycerol and xylitol [62], corn starch with glycerol alone [70], glycerol plasticized rice starch [71], amaranth flour plasticized with sorbitol or glycerol [68], cassava starch with glycerol [72], cush-cush yam starch [73], and pea starch with glycerol [74]. On the other hand, their tensile strength values were lower than LDPE and polystyrene [63].…”

“…In the case of GS-plasticized films, tensile strength reduction was observed from 15.82 to 3.99 MPa at the same range of plasticizer concentration. The decrease in tensile strength of starch based films as plasticizer concentration increased were reported by numerous authors [6,7,30,52,[58][59][60][61][62][63][64][65][66][67]. This phenomenon can be explained through the role of plasticizers in diminishing the strong intra-molecular attraction between the starch chains and promoting the formation of hydrogen bonds between plasticizers and starch molecules.…”

“…According to Adhikari et al [61], when multiple plasticizers are utilized in film matrix, strong interactions may occur between the plasticizers (plasticizer-plasticizer interactions); which can improve certain functional properties of the film. Elsewhere, Muscat et al [62] also emphasized the significance of blending two plasticizers, especially polyols, at different concentrations to evaluate their effectiveness in developing starch based films.…”

Facile Preparation of Starch-Based Electroconductive Films with Ionic Liquid

“…Nevertheless, between the granule and molecular levels, there are alternating amorphous and semicrystalline shells (growth rings) (100~400 nm), with the latter shell being stacked crystalline and amorphous lamellae (periodicity) (9~10 nm).

Characterization of starch films impregnated with starch nanoparticles prepared by 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-mediated oxidation

“…The film preparation was performed by following Fu, Wang, Li, Wei, and Adhikari (2011) method with some modifications. In brief, 7.0 g of previously dried (40°C for 6 h) MS and 3.0 g of plasticizer (glycerol) was added to 100 ml of deionized water to form starch-plasticizer dispersions with a 10.0 wt% (w/v) solid concentration.…”
