Online published on 26 December, 2017. Abstract A total of six released tomato hybrids viz., Swarna Baibhav, Swarna Sampada, Swarna Samridhi, Swarna Vijaya, Swarna Deepti, Swarna Anmol and two open pollinated tomato varieties viz., Swarna Lalima and Swarna Naveen of ICAR-RCER, RC Ranchi were analyzed for their quality and nutritional composition at different stages of maturity. Swarna Samridhi recorded highest antioxidant activity (26.17%) and highest TSS (7.6%) at fullyripe stage. Ascorbic acid was highest at Swarna Naveen (21.75 mg/100 g) at fully ripe stage. All genotype showed marked increase in antioxidant activity and ascorbic acid content from green to breaker stage. TSS was recorded highest at fully ripe stage due to breakdown of starch and polysaccharides. Hence, fully ripe tomato is best for consumption in terms of nutritional quality. Top Keywords Tomato, antioxidant activity, ascorbic acid, TSS, nutritional quality. Top |
