Effect of steaming and sulfur fumigation on the morphology of Gastrodia elata starch granules. Scanning electron microscopy (SEM) images of G. elata starch granules [(a,e) nonsteam and nonsulfur fumigation treatment (NSt-NSf); (b,f) nonsteam and sulfur fumigation treatment (NSt-Sf); (c,g) steam and nonsulfur fumigation treatment (St-NSf); (d,h) steam and sulfur fumigation treatment (St-Sf)]. AFM images of G. elata starch granules after gelatinization for 10 min of NSt-NSf (i), NSt-Sf (j), St-NSf (k), St-Sf (l). Confocal experimental images of G. elata starch granules after gelatinization for 10 min [(m,q) NSt-NSf; (n,r) NSt-Sf; (o,s) St-NSf; (p,t) St-Sf].
