Allen et al.37 studied the gelatinization of tapioca starch by taking samples from a Brabender ViscoAmylograph. Water penetrates to the middle of the granule from the truncated end. At 50°C, well below the starch gelatinization temperature, there is... [Pg.552]

The Rapid ViscoAmylograph (RVA) has been the preferred instrument for determining the pasting properties of rice flour and rice starches24,25 (see Chapter 8). [Pg.575]

Heat-induced changes in rye starch dispersions have been studied using the Brabender ViscoAmylograph.11 The problem with this method is that the changes monitored are... [Pg.585]
