In this study, an approach for designing a neural network
based on genetic algorithm has been used to model mass
transfer during osmotic dehydration of potato slices. The
experimental data were obtained through a complete
randomized design with different osmotic solutions (5, 10
and 15% w/w) and potato to solution ratios
(1:6,
1:8
and 1:10)
at varying temperatures (30, 40 and 60°C) and the best model
obtained with optimization of a multi-layer perceptron
neural network had a mean absolute error of 0.260, 0.516 and
0.137 for moisture content, water loss and solid gain of
osmotically dehydrated slices respectively.
