Resumo: | Three varieties of cassava (Manihot esculenta Crantz) with possibilities of utilization in alcohol production were submitted to natural (23 ± 2ºC) and artificial (40 and 60°C) drying. Roots of several sues were cut into slices of 0,5 cm thickness with diameters ranging from 2.5 cm to 6 cm. Typical curves of water loss as a function of slice diameters and specific surface were made for each variety at the experimental conditions. Drying rates were affected by the root variety. The starch content remained almost the same after each treatment, as indicated by chemical and microscopic analyses. These results are of interest in the application of drying techniques for cassava preservation during handling and storage at the alcohol production plants. |

As raízes, de tamanhos diversos, foram cortadas em fatias de 0,5 cm de espessura, com diâmetros variando entre 2,5 cm e 6 cm. Curvas típicas de perda de água em função dos diâmetros e superfície específica foram obtidas para cada variedade, nas condições experimentais sob estudo. As curvas de velocidade de secagem revelam diferenças significativas na cinética de remoção de água, para as diferentes variedades. Além da análise de secagem, foram avaliados os teores de amido para cada caso, não tendo sido encontradas perdas significativas nos métodos de secagem utilizados. Estes resultados são de interesse na aplicação de técnicas de desidratação na preservação de mandioca utilizável nas usinas de álcool.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraChieppe, F.Carvalho, V.
