Tryton Foods, best-known for Aunt Bessie’s Yorkshire puddings, is cutting 30 jobs in Hull.
The jobs will go as production of some goods is transferred from a subsidiary unit to the main Tryton plant in the city.
A spokesman commented that the company was continuing to grow, but needed to make efficiency savings to ensure future success.
In an official statement, Tryton said: "These changes will take place by this summer and while it is anticipated that the vast majority of the workforce will move to the new locations, sadly there will be a number of redundancies."
It continued: "These are not expected to exceed 30 roles and the company is confident that the majority of these will be through voluntary means. Where possible, redeployment will be offered."
The company employs approximately 500 people in Hull and also makes frozen pies and desserts.
