Drying kinetic and shrinkage circumstance of Persian shallot bulb
Abstract: The drying kinetics and volume shrinkage of Persian shallot bulb were looked at during air-drying. Six mathematical drying kinetics models were used, the non-linear page models represents good agreement with experimental data with average of Mean Relative Absolute Errors as 1.77%. Liner and exponential models were fitted to volume shrinkage containing with coefficients of determination from 0.956 to 0.998.
