• Optimisation of raw tooke flour, vital gluten and water absorption in tooke/wheat composite bread: Effect of raw tooke flour and vital gluten on wheat flour physicochemical and dough rheological properties (Part I)

AbstractFull-Text PDF

Raw Tooke Flour (RTF) is a generic, shelf stable flour from matooke (a cooking banana variety) targeting the baking industry. However, its lack of gluten has hampered development of RTF/wheat composite bread. It is thus necessary to optimize levels of substitution of RTF into wheat flour with vital gluten as a processing aid for improving rheological and baking properties. The specific objective of this study was to... Read more.

• Optimisation of raw tooke flour, vital gluten and water absorption in tooke/wheat composite bread, using response surface methodology (Part II)

AbstractFull-Text PDF

  The objective of this study was to optimise raw tooke flour-(RTF), vital gluten (VG) and water absorption (WA) with respect to bread-making quality and cost effectiveness of RTF/wheat composite flour. The hypothesis generated for this study was that optimal substitution of RTF and VG into wheat has no significant effect on baking quality of the resultant composite flour. A basic white...

• Functional and sensory properties of wheat (Aestium triticium) and taro flour (Colocasia esculenta) composite bread

AbstractFull-Text PDF

  Functional and sensory properties of wheat (Aestium triticium) and taro (colocasia esculenta) composite bread were investigated. Unblanched and blanched flour were produced from taro tubers. These were separately used to formulate composite flour blends with wheat flours in ratios of 70:30, 80:20 and 90:10. Functional properties, water absorption capacity (WAC), oil absorption capacity (OAC), packed bulk... Read more.
