Increase in the TP content and consequently in FRP could be expected in yoghurt with higher levels of carrot juice. However, due to the relatively lower TP content (46.25±1.27 mg GAEkg1) in the carrot juice used in this research,increase in the TP content and FRP of the yoghurt through carrot
juice supplementation was subtle. This is also in part contributed by
high binding of phenolic compounds to milk casein proteins before
its gel formation on fermentation. Similar insignificant change in
the total phenolic content and FRP in yoghurt was reported when
grape seed extract phenolics was supplemented into milk before
inoculation-fermentation (Chouchouli et al., 2013). The TP content
of carrot can vary depending on the cultivar, pre-harvest management, postharvest handling, storage and processing methods(Sharma et al., 2012). The results showed, due to increased carotenoids and a supply of other possible phytonutrients like ascorbic acid, phenolics, tocopherols andfibers from carrot juice, that there
is a possibility to improve yoghurts with potential to supply antioxidant, pro-vitamin A and dietaryfibers.
