To study the effect of the mixing, three types of starch from Dioscorea sp., Dioscorea piperifolia Humb.var. Wild. and Dioscorea Trífida tubers were mixed in different proportions and their thermal, structuraland rheological properties were characterised. Using thermogravimetric (TG) and differential thermalanalysis (DTA) it was found that all the mixed samples presented enhanced thermal stability. By differ-ential scanning calorimetry (DSC) and viscoamylograph (RVA) techniques it was verified that the amylosecontent from the D. sp. starch influenced the gelatinisation and paste properties of the mixed samples.Furthermore, using scanning electron micrograph (SEM) analysis it was possible to suggest a correlationbetween the size of the starch granules and their relative degree of crystallinity, which was calculatedby the X-ray diffraction (XRD) patterns. The colour analysis revealed that, irrespective of the proportion,the strong tendency to yellow of the native Dioscorea piperifolia predominated in the mixed samples. |
