Abstract

Starch, the most important component in cassava, has been largely used by the food industry. This work aimed at evaluating the starch content variation (%) in six cultivars namely Fecula Branca, Olho Junto, Fibra, Verdinha, Espeto and Mico. Planting took place from October 1998 in Marechal Cândido Rondon, Brazil. Cultivars were sampled between the 7th and the 10th month of plant life. Starch content evaluation (%) was calculated by the hydrostatics scale method. Fecula Branca, Olho Junto and Fibra cultivars presented the largest amount of starch content, 29.7%, 29.1% and 29.1% respectively. The Mico cultivar, on the other hand, had the poorest performance regarding starch accumulation, 25.0%. As for the starch content profile along the periods studied, it was verified that the Fecula Branca, Olho Junto, Verdinha and Espeto showed a stable pattern, while the Fibra and Mico cultivars tended to develop more progressively.

巴西Marechal ndido Rondon地区4个收获季节木薯品种淀粉含量变化

淀粉是木薯中最重要的成分，已被食品工业大量使用。本研究旨在评价6个品种(Fecula Branca、Olho Junto、Fibra、Verdinha、Espeto和Mico)淀粉含量的变化(%)。从1998年10月开始在巴西的Marechal ndido Rondon种植。在植株生长的第7 ~ 10个月之间对品种进行取样。淀粉含量评价(%)采用流体静力学比例尺法计算。淀粉含量最高的品种分别为黄竹、青花和纤维，分别为29.7%、29.1%和29.1%。而Mico品种淀粉积累量最差，为25.0%。从不同时期的淀粉含量变化来看，Fecula Branca、Olho Junto、Verdinha和Espeto的淀粉含量变化趋势较为稳定，而Fibra和Mico的淀粉含量变化趋势较为缓慢。
