Abstract

The study aimed to find the optimal conditions for the production of tomato paste with 2-level rotatable design and multi-objective optimization using the desirability function approach. 20 laboratory experiments were conducted to build the objective function that describes the influence of
maltodextrin on the rate of additional services before the sun spray, drying air temperature, pump speed input to the spray drying process. By means of expected function it was able to solve multiobjective optimization for determining the optimal mode for spray drying tomatoes translated as
follows: the ratio of maltodextrin/juice dry matter 52%, drying air temperature 133 0C, the rate of input pump 27 ml/min. At this condition, the performance reached 74.2% and lycopene content of the
product is 43.334 mcg%.
