Abstract: 

Tomato (Solanum lycopersicum) is known to be associated with a reduced risk of developing a certain chronic diseases and cancers due to the presence of lycopene, a bioactive carotenoid. The objective of this study was to determine the antioxidant activity in tomato powder and TP extrudate (Tomato powder incorporated extrudate). The results of present study showed that flavonoid content in tomato powder incorporated extrudate of IC50 value in control extrudate (22.28±0.01) was more when compare to the TP extrudates (15.51±0.01). The results of phytochemical screening showed that carbohydrates, alkaloids, proteins, amino acids, flavanoids, fixed oils and fats, terpenoids, cardiac glycosides, saponins and phenols are present in TP extrudates. Identification of carbohydrates, alkaloids, proteins, amino acids, flavanoids, cardiac glycosides, saponins, tannins and phenols were present in tomato powder. As the concentration increased the antioxidant activity increased in the extrudates. Lower IC50 value indicates the more antioxidant activity. IC50 value for control extrudates was 13.23±0.02, tomato powder 8.78±0.01 and TP extrudate 10.87±0.09.
