GlaxoSmithKline is rolling its Juiced Up! Ribena range out to retailers to build on the juice drink's success in foodservice and grab a bigger share of the lunchbox market.

Available in a wedge format, Juiced Up! comes in raspberry and apple & blackcurrant variants (rsp: £1.79 for a four-pack of 180ml cartons). It is made from 85% natural fruit juices and 15% water, has no artificial ingredients, and counts as one of the recommended 5-a-day.

The variants, which were introduced exclusively to the foodservice sector in March, would rival pure juices in the lunchbox drinks market, said Andy Mahoney, brand manager.

"Last year, an additional 18 million lunchbox occasions were identified in the UK market, creating a huge opportunity for grocery ­retailers. The wedge format makes it an ideal compliment to any child's lunchbox," he said.
