Assessment of Antioxidant Activity, Phytonutrients and Nutritive qualities of selected Tomato Paste sold in Umuahia Metropolis:- Obikwelu, Chidinma L
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 ( l.43mg/1 00g) were
significantly (p<0.05) higher in Star tomato paste. Beta carotene (3 .02mg/1
00g) 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 .3 7mg/1 00g) 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.
