Horse chestnut (Aesculus hippocastanum L.) starch: Basic physico-chemical characteristics and use as thermoplastic material
(Elsevier B.V., 2014-11-04)
Starch isolated from non-edible Aesculus hippocastanum seeds was characterized and used for preparing starch-based materials. The apparent amylose content of the isolated starch was 33.1%. The size of starch granules ranged ...
Processing and characterization of thermoplastic starch/polycaprolactone/compatibilizer ternary blends for packaging applications
Thermoplastic starch (TPS)/polycaprolactone(PCL) blends were obtained by melt mixing. First, thebest formulation of thermoplastic starch (starch, plasticizerand additives) was studied. The obtained filmswere characterized ...
Poly(Ethylene Glycol) as a Compatibilizer for Poly(Lactic Acid)/Thermoplastic Starch Blends

Morphological, mechanical properties and biodegradability of biocomposite thermoplastic starch and polycaprolactone reinforced with sisal fibers
(Sage Publications Ltd, 2012-04-01)
The incorporation of fibers as reinforcements in polymer composites has increased due to their renewability, low cost and biodegradability. In this study, sisal fibers were added to a polymer matrix of thermoplastic starch ...
Food packaging bags based on thermoplastic corn starch reinforced with talc nanoparticles
Packaging bags from thermo-compressed films of thermoplastic corn starch containing talc nanoparticles (0, 1, 3 and 5% w/w) were developed. Mechanical properties of films were studied by two different techniques (tensile ...
Thermoplastic starch modified during melt processing with organic acids: The effect of molar mass on thermal and mechanical properties
(ELSEVIER SCIENCE BV, 2011)
Thermoplastic starch (TPS) was modified with ascorbic acid and citric acid by melt processing of native starch with glycerol as plasticizer in an intensive batch mixer at 160 degrees C. It was found that the molar mass ...
Strategies to improve the mechanical properties of starch-based materials: plasticization and natural fibers reinforcement
(Assoc Brasil Polimeros, 2014-07-01)
Biodegradable polymers are starting to be introduced as raw materials in the food-packaging market. Nevertheless, their price is very high. Starch, a fully biodegradable and bioderived polymer is a very interesting alternative ...
EXTRUSION AND CHARACTERIZATION OF THERMOPLASTIC STARCH SHEETS FROM “MACHO” BANANA.
Starch isolated from macho banana was oxidized by using 2.5% and 3.5% (w/w) of sodium hypochlorite. Native and oxidized starches with glycerol were processed using a conical twin screw extruder to obtain thermoplastic ...
Agro-industrial residue from starch extraction of Pachyrhizus ahipa as filler of thermoplastic corn starch films
Biocomposites films based on thermoplastic corn starch (TPS) containing 0.5% w/w fibrous residue from Pachyrhizus ahipa starchextraction(PASR) were obtainedbymelt-mixing andcompressionmolding. PASR ismainly constituted by ...
