Healthy Eating. Lycopene is the natural substance (part of the carotenoid group) responsible for the deep red color in many foods, most particularly in tomatoes. However, this fact is not what lycopene is most famous for.
Abstract. A central composite design was used to optimize the enzyme-assisted extraction of lycopene from the peel fraction of tomato processing waste. Tomato skins were pretreated by a food-grade enzyme preparation with pectinolytic and cellulolytic activities and then subjected to hexane extraction.he yield of lycopene extraction from untreated tomato skins was 4.1 Â± 0.3%, while the values determined for the enzyme-treated material were between 33.2% and 72.3% (mean value: 50.7%), depending on the set of operating conditions used (Table 3).
