Abstract

The rheological property of pineapple juice was investigated over a wide range of temperature (30 to 75°C) using a Couette rotational viscometer. The speed of rotation of the outer cylinder varied from 5.1 to 1021 s-1. The values of viscosity was in the range of 12.65 cP to 300 cP and was dependent on the temperature as well as the shear rate applied. From the results obtain, the test pineapple juice exhibited a non-Newtonian flow behaviour known as shear-thinning behaviour typical of pseudoplastic fluids. This was further confirmed using the Power-law and Herschel-Bulkley model. Arrhenius-type equation was used to analyse the effect of temperature on the juice and equation parameters were obtained. Thus, using the Arrhenius equation and parameters, the viscosity of pineapple juice at any temperature for a specific shear rate can be predicted. Coefficient of determination obtained were between 0.9 – 0.95
