ABSTRACT

An investigation was carried out to optimize the time, temperature and slice thickness for dehydration of tomato slices in vacuum oven so that the lycopene losses were minimized. The optimization was done using Box-Behnken method of design expert (R.S.M.), keeping other nutritional factors of tomato slices within range. Optimum conditions for vacuum drying were 2 hrs treatment time at at 80°C temperature and 7 mm slice thickness. The dehydrated product was found with 8.52 mg/100g lycopene which was close to the original value of lycopene found in raw tomatoes.
