4. Conclusions
Blanching temperature of potato slices affected the color
after frying; the higher the blanching temperature, the darker the color of potato chips. Using the adjoining face
method of analysis it was possible to detect significant
differences ðPo0:05Þ between blanched potato chips(control, 70 1C for 5 min) soaked in water or in NaCl
solutions. Soaking of blanched potato slices in NaCl
solutions improved significantly ðPo0:05Þ the final color
of the potato chips (less dark color) in comparison with
control potato chips.
This could have commercial implications, as potato
chips are often (dry) salted anyway. Using the adjoining
face method of analysis it was possible to find a significant
effect ðPo0:05Þ of the NaCl concentration on the final
color of the potato chips for the time and conditions of
NaCl soaking studied
