Starch - Stärke
Abstract This research is to investigate the breadmaking ability of three cassava starch varieties (96/1414, TME15, and YARA) grown in Cameroon. To achieve this, starch samples from each variety are collected before and during fermentation to determine chemical, rheological, and bread‐making properties. They are analyzed for pH, titratable acidity (TTA), lactic acid (LA), specific volume (SPV), and pasting properties using known method; These parameters are used to perform a principal component analysis (PCA). The morphological characteristics are studied by scanning electron microscope (SEM). Result shows that, there is a decrease in pH (6.21–3.8) with an increase in TTA (0.34–7.05) and LA (0.15–6.46) with fermentation time. In parallel, a decrease of pasting properties and an increase in SPV (1.15–2.82 cm 3 g −1 ) are observed. The PCA surrounds 96/1414 day 30, YARA day 30, and TME15 day 25 α 30 as the best samples, and the SEM shows a superficial degradation of the granules after fermentation. Thus, this study suggests that the optimal sour cassava starch for bread‐making can be obtained from 96/1414 day 30, TME15 day 25 α 30, and YARA day 30. The variety 96/1414 appears to have the best bread‐making ability while TME15 appears to be most suitable for short fermentation time.
