Not AvailableThis study was envisaged to investigate the effect of particle size on the rheological characteristics of
mango cv. Bangalora peel powder under ambient conditions using a rotational rheometer. The consequences
of sample concentration, i.e., powder: water (1:4, 1:5, 1:6) was also evaluated. Sieve analysis using screens
(420, 355, 250, 125 microns) was done to achieve the desired va riation in particle size. Shear stress-shear rate
data was adequately fitted to Herschel-Bulkey, Power law and Casson law and the rheological properties were
represented graphically by rheograms for 0 to 100 s-1 shear rate. Relative parameters and regression analysis
against each model determined the flow characteristics of the samples. Selected three models showed well
representation of the rheological data, with high regression coefficients. Model parameters (consistency
coefficient, flow behaviour index and R2) validated the deviation in rheological characteristics with particle size
and sample concentration. Shear stress (τ) increases steeply with sample concentration for equivalent particle
size, however, for the same sample concentration, negative correlation of particle size with shear stress was
reported. The identification of suitable particle size and sample concentration might be useful in understanding
of rheological properties of the peel powder of selected cultivar.Not Availabl
