Abstract

1994年,1995年にわたり,7品種の甘藷を,標準,早掘マルチ,長期マルチの条件で栽培した.肉色,栽培条件,年次が,澱粉,繊維質含量および澱粉特性,すなわち,アミロース含量,示差走査熱量計による糊化特性に与える影響について調べた.肉色がオレンジの品種は,白色や紫色のものに比べ,繊維質含量に対する澱粉含量の割合が低く,アミロース含量は高かった.栽培条件の違いにより,示差走査熱量計で求めた澱粉の糊化開始温度,糊化温度範囲,糊化熱の差異は大きかった.早掘マルチでは糊化開始温度が高く,糊化温度範囲が小さかった.標準栽培による澱粉の糊化熱は他の栽培条件と比べ小さかった.

Seven sweet potato (Ipomoea batatas) cultivars were grown in 1994 and 1995 by standard harvesting (SH), early harvesting with mulch (EHM) and late harvesting with mulch (LHM). The effects of flesh color, cultivation method and year on starch and cell-wall material (CWM) contents and starch characteristics [amylose content and gelatinization properties by differential scanning calorimetry (DSC)] were tested. Orange flesh cultivars had a lower ratio of starch to CWM content and a higher amylose content than purple and white flesh cultivars. In almost all cases, cultivation method and year had little impact of starch, CWM and amylose contents. Significant differences in DSC thermograms were seen among cultivation methods, showing the highest values of onset temperature for gelatinization, lowest values in the gelatinization range at EHM and lowest values in gelatinization heat at SH. Yearly effects on DSC characteristics were not observed.
