Why is E282 in bread?

To prevent mould. Commercially produced bread needs to stay fresh for 7–14 days during distribution and shelf display. Without E282, sliced bread would develop mould within a few days of production.

Does sourdough contain E282?

Traditional sourdough does not. The natural fermentation process in sourdough produces organic acids that inhibit mould, acting as a natural preservative. This is one reason sourdough has a longer shelf life than other preservative-free breads. However, some mass-produced "sourdough-style" loaves may still contain E282.

Is E282 banned in any countries?

No. E282 is approved for use in the EU, UK, US, Canada, Australia, and most other countries. It is one of the most commonly used preservatives in commercial baking worldwide.

What is E282? (Food Additive Explained)

E282 is calcium propionate — a preservative widely used in bread and bakery products to prevent mould growth. It extends shelf life and is found in most commercially produced sliced bread in the UK.

What is E282?

Full name: Calcium Propionate

E282 is the calcium salt of propionic acid. Propionic acid occurs naturally in some foods (it's produced during Swiss cheese fermentation, for example), but as a food additive, calcium propionate is manufactured industrially. It's classified as a preservative and has been used in commercial baking since the mid-20th century.

What does E282 do in food?

E282 inhibits the growth of mould and certain bacteria in bread and baked goods. Without it, commercially produced bread would develop visible mould within 2–3 days. With E282, shelf life extends to 7–14 days — essential for supermarket distribution. It works by lowering the pH environment, making it hostile to mould spores. It has no effect on taste or appearance at the concentrations used.

Where is E282 found?

E282 is commonly found in:

Sliced bread (white, wholemeal, seeded)
Bread rolls and buns
Wraps and tortillas
Crumpets and English muffins
Pre-packaged bakery products
Some processed cheese products

Is E282 bad for you?

E282 is approved as safe by EFSA and the FDA with no specified daily intake limit. It is metabolised by the body in the same way as naturally occurring propionic acid. There is no strong evidence linking it to adverse health effects in adults at dietary levels. Some limited studies have explored links to irritability in children, but these findings have not been widely replicated or accepted by regulatory bodies. The main concern with E282 is not the additive itself, but what its presence tells you about the bread — it's a clear signal of industrial production.

Why E282 matters for food choices

E282 is a useful litmus test for bread quality. Artisan and bakery-fresh bread doesn't need preservatives because it's sold and consumed quickly. When you see E282 on a label, it means the bread was made to survive long supply chains — factory to warehouse to shelf. Under the NOVA system, bread containing E282 and other preservatives is more likely to be classified as ultra-processed. Comparing a simple sourdough (flour, water, salt) to a supermarket loaf (with E282, E471, E472e, and more) reveals a significant processing gap.
