Sainsbury's Strawberry Low Fat Yoghurt

I noticed a rather unexpected ingredient in Sainsbury's strawberry yoghurt today...

Carrot juice? Really? In yoghurt? I had a look at the peach and raspberry yoghurts sitting in the fridge, they don't have carrot juice in them... what's so special about strawberry yoghurt that it needs a carrot's squeezings to set it off right?
