Physical–chemical, thermal, and functional properties of achira (Canna indica L.) flour and starch from different geographical origin

摘要: Achira (Canna indica L.) is a plant native to the Andes in South America, starchy source, and its cultivation has expanded different tropical countries, like Brazil. In order evaluate potential of this species, starch flours with particle size were obtained from Brazilian achira rhizomes. Proximal analyses, distribution, SEM, swelling power, solubility, DSC, XRD analysis, FTIR performed for characterization these materials. Flours showed high dietary fiber content (16.5–32.2% db) concentration case smaller fraction. Significant differences protein content, thermal properties observed between Colombian starch. All studied materials displayed B‐type pattern relative crystallinity 20.1% flour 27.0 28.0% starches. Results that produced rhizomes have great technological use as functional ingredient food industry.
