Feasibility of recovery of bioactive principles from residues of tomato industrialization

Abstract

The industrialization of tomato causes a large amount of waste with no economic value that contains bioactive compounds. The objective of this work is to extract lycopene from skin, fiber and seeds obtained from the tomato industrialization process. Sampling of waste from a local industry was carried out, in order to reduce humidity and achieve conservation, the samples were dried in a horizontal, tray, batch tunnel kiln, varying two parameters in an experimental statistical design of the type 23, the selected variables were temperature and air flow rate. The response variable was the lycopene content of the dehydrated samples for the same humidity level. In the samples of dehydrated residues, lycopene quantities were lower than expected in relation to the concentration of solids, varying in a range from 120 to 147 mg of lycopene / kg of residues with 7% humidity. It was observed that degradation as a result of dehydration caused losses between 88 and 90%. The lycopene quantified in the dehydrated residues of tomato industrialization did not respond to the amount of water removed.
