PepsiCo is beefing up ­another two flavours in its Walkers crisps range to give them a more contemporary image. Beef & Onion and Barbecue have been reformulated and will be renamed Steak & Onion and BBQ Rib respectively.

Five of the 12 flavours in the core range have been updated this year, while three new recipes were added in February, as part of a ­relaunch with reduced salt and fat. The company claims sales have since risen by 13%.

Trade marketing mana­ger Cara Beeby said early indications were that sales of Steak & Onion would increase by 20% and BBQ Rib by 30%.
