Can you eat sourdough bread on a vegan diet?

Sourdough is usually made from four main ingredients, flour, salt, water, and a sourdough starter, which usually consists of flour and water. However, nowadays, there are several products on the market containing all sorts of animal-derived ingredients which are still labeled as sourdough. This is why it is always fundamental to pay attention!

Things to watch out for when buying sourdough

Enriched sourdough: Many brands tend to enrich their sourdough with ingredients that are not fully vegan, such as milk, eggs, or butter. To see whether the brand you chose is among these, you will have to check out each ingredient. On average, the less the better.

Sweetened sourdough: Unfortunately, some brands also decide to smooth the sourness of their products by adding sweeteners. Even though most of these are suitable for vegan diets, others aren’t. The most common one among these is honey, so always read your label to make sure this ingredient has not been added to the mix.

Sourdough starters: As we mentioned above, a traditional sourdough starter should be composed of only flour and water. However, some companies add other non-vegan food to boost its activity, such as honey and milk. Unfortunately, many brands simply list ‘sourdough starter’ among their ingredients. Whether or not you decide to consume these products depends on your level of strictness.

Artificial flavors: There is no way to know whether artificial flavors were made by using animal products, so always try to avoid these ingredients when buying items from your local supermarket.

Mono-glycerides and diglycerides: Mono-glycerides and diglycerides are forms of fat often used to modify the texture of sourdough and preserve its moisture. Unfortunately, even though they often come from soybean oil, they can also be animal-based.

Lecithin: Similarly to mono-glycerides and diglycerides, Lecithin is often derived from soybeans. However, in some instances, it may come from egg yolks.

Datem: Datem, also known as E472e, is an emulsifier that can be derived from animals.

Questions to ask your baker

You should ask these to find out if their sourdough bread is vegan

Ok, now you know how to get one hundred percent vegan sourdough bread when buying from a supermarket. But what if you get your bread from a baker? There are a few questions you may want to ask, to make sure the products are fully plant-based. 

  • First of all, ask whether their sourdough is enriched and, if yes, with what. 
  • Second, check whether it has been sweetened with honey or other animal products. If you are very strict with your diet, you may also want to ask what their loaf tins are usually greased with. Some bakers, in fact, use animal fat and you definitely want to avoid that. 
  • You may also want to ask if they tend to butter their bread after it comes out of the oven and whether they fed their sourdough starters with anything besides flour and water. 

This way, you’ll be one hundred percent sure that these products are suitable for a plant-based diet.
