Gluten Free Diet Advice

  • Is the oil used with McCain's products gluten free?

    We use a mixture of oils for different products. For example, some products use sunflower oil, whilst for others we use a rapeseed/sunflower blend and for our roast products we use goose fat/beef dripping. Please always check the packaging before purchasing to ensure the product is suitable for you.
  • Are potatoes gluten free?

    Potatoes are naturally gluten free as they are not cereals; they are a type of starchy vegetable. We make lots of potato products to suit different dietary needs and tastes. Some of our recipes include wheat, so please always check the ingredients on the back of pack or on our site. All allergens are shown in bold and capitalised here.

  • Are hash browns gluten free?

    Our hash browns are made in an environment where other products contain wheat. Therefore, we are unable to guarantee our hash browns are 100% gluten free.

  • Are jacket potatoes gluten free?

    Yes, our jacket potatoes are gluten free. Our jacket potatoes are simply made using whole fresh potatoes which are slow baked with a small amount of sunflower oil.

  • Are chips gluten free?

    We follow a strict process from the farm through to the packet to ensure our chips are gluten free. By doing this, we closely control all the ingredients which go into our products to guarantee they are suitable for consumption.

    Our gluten free home chips, naked oven chips crinkle cut, naked oven chips straight cut, skin on fries, quick chips straight cut, quick chips crinkle cut and quick cook french fries are all gluten free.

    We are now making our Gastro Chips at a different McCain facility; the product made there is gluten free and is correctly labelled as such. As our Gastro Chips have an 18 month shelf life, some product may still be in the market, or possibly in your freezer at home, that was not made at this facility and will have ‘may contain wheat’ printed on pack. New product will not have this on pack. However, it is important to note that both products are correctly labelled.  We would encourage you to please always check the ingredients declaration on the back of each pack. We’d like to reassure you that the information on pack is correct and will depend on which McCain facility the product was made in.

    From time to time our recipes and production alter, therefore it is important to always check the back of each product for any allergy or dietary information.
