Description There has been considerable interest in the value of carotenoids
due to their high nutritional and nutraceutical properties. We have
earlier shown that agroinfiltration with Agrobacterium tumifaciens
GV 3101 containing binary vector pRI 101(I) harboring CrtI gene
(Phytoene desaturase) and binary vector pRI 101(Y) harboring CrtY
gene (Lycopene β-cyclase) from bacterial sources increases carotenoids
in tomatoes. In the present study, the juice prepared from
fruits having CrtY gene had higher content of β-carotene (0.60 mg
100mL−1), lycopene (0.40mg 100 mL−1) and total phenolics (11.41
μg GAE mL−1) compared to juice prepared from control fruits
(0.47 mg 100 mL−1, 0.32 mg 100 mL−1 and 11.22 μg GAE mL−1,
respectively), and it showed better antioxidant potential (DPPH
IC50 value of 27.6) than that of non-transgenic fruit juice (56.4 μL
mL−1). The juice from fruits having CrtY gene also had lower
Bostwick value (7.5 cm min−1) than control fruits (9.8 cm min−1),
indicating improvement in processing quality because of gene
integration. Juice prepared from agroinfiltrated tomatoes may
benefit both consumers as well as juice processing industry due
to their high nutritional value and better processing quality.
