Starch with a granule size of 0.75 to 1.25 microns has been prepared from chunk starch of Amaranthus retroflexus by three different procedures. Physical properties of small-granule starch are different in some respects from those of chunk starch. In general, these differences might be explained by resistance of chunks to penetration of solvents. Viscosity curves resemble those of cow-cockle starch, suggesting that low pasting temperature, granule stability, and lack of retrogradation are associated with small-granule starches.
