Abstract

Application of Weibull model in the pile salting of goat meat slices was studied to predict the moisture and salt contents and determine the effective water diffusion coefficient (De). The high coefficients of determination (R2 > 0.99) and low mean relative error (< 10%) indicated the acceptability of Weibull model for predicting both the moisture and salt contents and determining De. Values of scale (α) and shape (β) parameters of Weibull model for fractional amount of moisture content ranged from 0.667 to 0.873 day and from 0.527 to 0.743 day, respectively. Values of α and β parameters of Weibull model for fractional amount of salt content ranged from 0.350 to 1.192 day and from 0.578 to 0.885 day, respectively. Values of De ranged approximately from 1.66 × 10-10 to 2.44 × 10-10 m2/s.
