title: Comparison of physicochemical properties of B-type nontraditional starches from different sources.
abstract: Starches were isolated from rhizomes of Curcuma longa, Canna edulis and Canna indica and bulbs of Lilium lancifolium, and showed a B-type X-ray diffraction pattern. Their physicochemical properties were investigated and compared. These starches showed significantly different granule morphologies and sizes, but all had eccentric hila. The C. longa starch had the lowest content of amylopectin short branch-chain and branching degree and the highest content of amylopectin long branch-chain, and the L. lancifolium starch the highest content of amylopectin short branch-chain and branching degree and the lowest content of amylopectin long branch-chain among the four starches. The L. lancifolium starch had the lowest resistance to gelatinization, and showed the lowest pasting peak, hot and final viscosities, and the C. longa starch had the highest resistance to gelatinization, and showed the highest pasting hot, final and setback viscosities and the lowest pasting breakdown viscosity. The C. longa and L. lancifolium starches possessed very high and low resistance to hydrolysis and digestion, respectively. The above physicochemical properties would be useful for the applications of B-type starches in food and nonfood industries.
