The company, which processes branded fruit juice and canned food, told FoodManufacture.co.uk no further information could be disclosed until the review was completed.
Princes has 11 manufacturing sites in the UK, including Bradford, Belvedere, Cardiff, Chichester, Eden Valley, Erith, Glasgow, Long Sutton, Manchester and Wisbech.
The news was revealed after a source told FoodManufacture.co.uk that the Princes juice facility in Newton Heath, Manchester, was to close, with production moving to Cardiff.
However, a Princes spokesman said no decision had yet been made.
He said: “We are conducting a review of our business and operations, and until this process is complete, no further information can be disclosed. No decision has been made regarding the future of the Manchester site.”
Princes owns a portfolio of household brands and produces and distributes others under licence. Its brands include Princes, Crosse & Blackwell, Aqua Pura, Jucee and Napolina.
