Sainsbury’s multi-seeded bread is from their bakery. It is unlikely to be assembled on site but is possibly baked on site depending on the shop size. It doesn’t come wrapped in plastic but maybe the original dough did.
INGREDIENTS: Fortified British Wheat Flour (Wheat Flour, Calcium Carbonate, Iron, Niacin, Thiamin), Water, Sunflower Seeds (7%), Linseed (4.0%), Pumpkin Seeds (2.0%), Rye Flour, Oats, Wheat Gluten, Wheat Bran, Poppy Seed (1.5%), Quinoa (1.5%), Sugar, Salt, Yeast, Caramelised Sugar, Malted Wheat Flour, Flour Treatment Agent: Ascorbic Acid.
Compare and contrast with Hovis multi-seeded version wrapped in plastic.
Ingredients
Wheat Flour (with added Calcium, Iron, Niacin, Thiamin), Water, Seed Mix (13%) (contains: Toasted Brown Linseed, Toasted Sunflower Seeds, Pumpkin Seeds, Sunflower Seeds, Millet Seeds, Golden Linseed, Poppy Seeds), Yeast, Wheat Protein, Salt, Soya Flour, Malted Barley Flour, Granulated Sugar, Barley Flour, Preservative: E282, Caramelised Sugar, Barley Fibre, Emulsifier: E472e, Flour Treatment Agent: Ascorbic Acid
They’re almost the exact same ingredients with the Hovis one also having emulsifiers and preservatives.
I’d call the first one processed and the second ultra-processed.
