Description
Achu is a paste traditionally made from taro corms by boiling, peeling and pounding in a mortar to a smooth and homogeneous consistency. The present study aims to define alternative and rapid methods to evaluate the textural hardness of achu reconstituted from taro flour. The creep recovery behaviour of achu samples made from flour of five varieties of taro was evaluated on a controlled-stress rheometer. The functional properties of the taro flours, the sensory analysis of hardness and the acceptability of reconstituted achu were also evaluated. The results showed significant variation in the functional properties of the flours. The rheological properties of the achu, the sensory hardness and overall acceptability were also significantly influenced by the variety. In general, flour which absorbed more water tended to produce achu with high level of newtonian compliance and retarded elastic compliance. The creep steady state shear compliance and the viscoelasticity index of achu, were significantly (P < 0.05) correlated to the sensory hardness. © 2007.
