Figure 7.
Transmission electron microscopic images indicate the effect of heat treatment on the prepared Idli rice product compared with the control Idli (No Heat Treatment) [58]. (a) The fine particle size of raw rice (Magnification at 100 μm); (b) heat-treated rice particles with increased starch content (Magnification at 100 μm); (c) the rough surfaces of the raw rice particles (Magnification at 200 μm); (d) heat-treated rice particles with increased starch show smooth surfaces (Magnification at 200 μm).
