Última Effect of relative humidities on microstructural, barrier and mechanical properties of Yam starch-monoglyceride films BABT Ferreira,Fábio Avelino Bublitz; Grossmann,Maria Victória Eiras; Mali,Suzana; Yamashita,Fábio; Cardoso,Lisandro Pavie. The effect of monoglyceride on microstructural, barrier and mechanical properties of casted yam starch films were investigated in different relative humidities (RH) and compared with glycerol-starch films. A single screw extruder was used to produce the starch - monoglyceride complex before film production and this process was effective to inhibit the phase separation in films. The addition of the hydrophobic compound reduced hydrophobicity, transparency and water vapor permeability of films. This later value for starch-glycerol film (1.7 x 10-10 g Pa-1 s-1 m-1) was higher than starch (1.2 x 10-10 g Pa-1 s-1 m-1) and monoglyceride-starch films (1.0 x 10-10 g Pa-1 s-1 m-1). Films containing glycerol had higher relative crystallinity (B and V H) with a... Tipo: Info:eu-repo/semantics/article Palavras-chave: Biodegradable films; Hydrophilicityandglycerol-monoestearate.

Tecnol. Aliment. ALVARADO,Sofia; SANDOVAL,Glória; PALOS,Isidro; TELLEZ,Simón; AGUIRRE-LOREDO,Yaneli; VELAZQUEZ,Gonzalo. Abstract Composite films of chitosan, fish gelatin and microbial transglutaminase (MTgase) were developed. Films were produced by the casting method and dried at room temperature for 30 h, conditioned for 7 days at 30 °C at a relative humidity (RH) from 11 to 90%, and characterized. Chitosan:fish gelatin films in different proportions (100:0, 75:25, 50:50) with MTgase, were subjected to tensile properties and water vapor transmission (WVT) testing. The results showed that tensile strength decreased with an increase in RH and with an increase in gelatin content. Percent of elongation also increased with increasing RH and gelatin concentration. Water vapor transmission showed an increase proportional to an increase in RH with the presence of gelatin being...

Tecnol. Aliment. CAMPO,Camila de; COSTA,Tania Maria Haas; RIOS,Alessandro de Oliveira; FLÔRES,Simone Hickmann. Abstract Biodegradable films blends made of safflower oil nutraceutical capsules waste corn starch (20:4, 30:4, 40:4 and 50:4) were prepared. The objective of this study was to evaluate the influence of addition of different concentrations of safflower oil nutraceutical capsule waste in the mechanical properties (tensile strength, elongation at break, Young’s modulus) and thickness of corn starch films. A decrease in tensile strength and Young’s modulus and an increase in elongation at break were observed with the increase in the content of the nutraceutical capsule waste. The results showed that the blends of safflower oil capsules waste-corn starch films demonstrated promising characteristics to form biodegradable films with different mechanical...
