Daftar Isi:
- Cassava flour was obtained trough the following steps: peeling, washing and slicing fresh cassava into chips, submerged into water and fermented with Lactobacillus plantarum subsp. plantarum NBRC 15891 for 10 days, drying, grinding and sieving to pass 60 mesh to produce cassava flour. The aim of this study was to determine the effect of fermentation duration and sucrose addition on baking expansion of cassava flour preapare from fermented cassava chips using L. plantarum subsp. plantarum. The method involved fermentation of cassava chips with L. plantarum subsp. plantarum and sucrose addition (0, 1, 2 and 3%) for 10 days. Analysis included acid content, pH, baking expansion properties, amylose content, viscosity and observation of starch granules in the flour. The resulted showed that the highest baking expansion of cassava flour was produce from fermented cassava chips by L. plantarum subsp. plantarum with 2% sucrose addition during 8 days. The Baking expansion expressed as specific volume was 8.20 ml/g, containing acid 1.15%, amylose 33.13%, pH 3.63 and viscosity 17.5 dPa�s.
