Abstract

Mango pulp was tested for time-independent and time-dependent flow properties using a coaxial cylinder rheometer. Mango pulp is a pseudoplastic liquid with yield stress, and exhibits thixotropic properties. Yield stress, calculated using the Casson or Bingham plastic models, had markedly higher values than those determined by stress relaxation, controlled stress experiments, or from stress-strain plots. Yield stress of the mango pulp was sensitive to temp. and decreased rapidly as temp. increased. The time-dependent model of Weltman was found to be most applicable (r <greater than or equal to> 0.991, P <less than or equal to> 0.01) for mango pulp.
