The thermal stability of starch cross-linked with tetraethylene glycol diacrylate was studied under nitrogen atmosphere by thermogravimetry (TG) and infrared spectroscopy (FTIR). The cross-linking reaction was confirmed by the increase in intens[...]texto impreso
Moisture sorption isotherms of high amylose corn starch (HACS) films at 5, 25, 35 and 45 oC within an approximate water activity (aw)range of 0.11–0.85 were obtained using a static gravimetric method. HACS films fitted a type III BET model at al[...]Article : texto impreso
En hojas manuales cargadas con arcilla, el almidón catiónico mejoró la retención de la arcilla y minimizó su efecto deletéreo sobre la resistencia a la tracción.texto impreso
Effects of plasticizers (glycerol, sorbitol, and 1:1 mixture of glycerol and sorbitol) on moisture sorption characteristics of cassava starch films were investigated at three levels of plasticizer concentration (0, 20, and 40 g/100 g starch). Th[...]texto impreso
Water transport in edible films of starch based products is a complex phenomenon due to the strong interaction of sorbed water molecules with polymeric structure of starch. Water sorption isotherms on high amylose starch based films are highly n[...]
