Characterization, Functional Properties, and Resistant Starch of Freshwater Macrophytes

Figure 1

Starch granules of aquatic macrophytes captured (a–h) under polarized microscope, 40X magnification and (b, d, f, h), under scanning electron microscope: (a, b) Colocasia esculenta corm, (c, d) Eleocharis dulcis corm, (e, f) Sagittaria sagittifolia corm, (g, h) Nelumbo nucifera rhizome, (i, j) Nelumbo nucifera seed, (k, l) Trapa bispinosa seed, (m, n) Typha angustifolia rhizome, and (o, p) Typha angustifolia seed. The yellow bar scale represents 10 μm length and 1 μm length for a, c, e, g and b, d, f, h, respectively. Arrows in the polarized image indicate the hilum (Maltese cross).
