On the back of annual results this week, the company revealed it had won a licence to sell official Olympic-branded biscuits and nuts at major retail outlets, c-stores and petrol forecourts across the UK.
The products, which will hit shelves in January, include tinned souvenir gift packs sporting logos for the Olympics and Team GB.
Zetar is testing a range of moulds for biscuits that are likely to include famous London landmarks such as red buses, Wembley Stadium and the Olympic velodrome.
"I would be very disappointed if we don't do £2m a year sales on the back of this," CEO Ian Blackburn told The Grocer.
Zetar's results ending 30 April showed record sales from its confectionery business, but profits were affected by a dramatic rise in commodity prices in its natural product division.
The company's adjusted pre-tax profits have risen 6% on last year's £6.4m to £6.7m with EBITDA rising only slightly, to £9.8m.
Blackburn said commodity price rises had forced the company to negotiate price increases with retailers for some of its products of up to 40%.
