Assessment Of Antioxidant Activity, Phytonutrients And Nutritive Qualities Of Selected Tomato Paste Sold In Umuahia Metropolis
ABSTRACT
This work evaluated the phytonutrient, antioxidants activity and nutritive qualities of some selected tomato paste products sold in Umuahia metropolis. The phytonutrients, chemical, minerals, and antioxidant activity of tin tomato paste were determined by standards methods. The results showed that lycopene(4.20mg/100g), Vitamin C (12.76mg/100g) and Vitamin A (1.43mg/100g) were significantly (p<0.05) higher in Star tomato paste. Beta carotene (3.02mg/100g) and Vitamin E (11.14mg/100g) were highest (p<0.05) in Clappa paste, while phenol was highest (p<0.05) in Super delicieux paste. Sonia paste showed highest values for total sugar (31.6%) and PH (4.43), while Super delicieux paste had highest Total soluble solid (21.63%) and Clappa paste showed highest reducing sugar (16.16%). On the minerals, Sonia was highest (p<0.05) in calcium (2.36mg/100g) and Fe (1.89mg/100g). Star paste showed highest values of magnesium (13.61mg/100g) and potassium (30.44mg/100g), while in Super delicieux Na (15.37mg/100g) was highest. Strongest antioxidant activity was observed in Sonia paste for DPPH (62.07%), ABTS (41.00%) and FRAP (47.88%) respectively. The result reveled that Sonia tomato paste was the best in most of the measured variables than other paste. From the phytonutrients and antioxidant activity results. These tomato pastes can boost physiological health against degenerative disease.
