Abstract
The aims of this study were to determine the kinetics of dehydration of high yielding potato variety (Diamont), to
investigate the various process parameters influencing mechanical drying of potatoes and to develop baked product
from the dehydrated potato. From the developed equation it was found that the diffusion co-efficient increased with
the increase in temperature. The exponential relationship between diffusion co-efficient (De) versus inverse absolute
temperature (Tabs-1), activation energy (Ea) for diffusion of water HYV potato was found to be 7.98 Kcal/gm-mole. The
influence of loading density as well as thickness of the product on drying rate were determined and the power law
equations which described the relationship between drying rate constant and thickness gave an n-value of 0.4586 for
HYV of potato. Organoleptic taste tests demonstrated that among biscuits made of various proportion of potato flour
and wheat flour, the results of test panel showed that biscuit made of equal proportion (1:1) of potato flour and wheat
flour secured the highest score (8.0). All the other samples of each type of product were also accepted by the
panelists either as “like moderately” or “like slightly”.
