Mutton has been working in an interim role at Storck for the past two years. He has also worked for Baxters Food Group as sales director, as well as at Kraft and Anchor Foods.
He replaces Richard Drayson, who after 18 years with Storck has decided to leave "to pursue other opportunities".
"Storck boasts a portfolio of genuinely loved brands that have a strong heritage in the UK," said Mutton. "We have excellent plans to capitalise on this consumer affection."
