Abstract

Physicochcmical properties of the Lotus root starch wert investigated. The shape of starch granules was elliptical with the average size of $20{\sim}35{\mu}$. Starch showed B-type X-ray pattern. The content of amylose was 22.1%. The blue value for starch and amylose were 0.280 and 0.692, respectively. The alkali number was 4.74. By X-ray diffraction examination, gelatinization began at $55^{\circ}C{\sim}60^{\circ}C$ and almost completed at $65^{\circ}C{\sim}70^{\circ}C$.
