By-products of the fermentation process, these aromatic compounds contribute to the flavour of sourdoughs.
Forms the outer layer of the endosperm of wheat and other grains. A source of enzymes which aid in the digestion of the endosperm.
A tool used to measure the flexibility of dough. It does so by inflating a thin sheet of dough with air until the dough ruptures. The results from this test indicate the most suitable uses of a flour.
A class of enzymes that catalyse the hydrolysis of starch to form simple sugars.
A chemical that inhibits the oxidation of other molecules or compounds. In the body antioxidants can protect cells against damage by free radicals. Examples include vitamin C, vitamin E and beta carotene. Antioxidants are found in foods such as wholegrains and leafy green vegetables.
An oxidising agent. Used by some bakers as a flour improver or dough conditioner to strengthen gluten and produce a loaf with greater volume and a finer crumb. Also used as an additive to dried yeast where it helps to produce the acid environment favouring faster yeast action.
A measure of a flour’s mineral content. The higher the ash count, the more minerals are present in the flour. This results in a stronger dough, and bread with a higher nutritional value and a better colour.
A stage in bread making when flour and water is mixed and left to rest, prior to making a dough. During this phase, enzymes in the flour begin to break down starch and proteins to form simple sugars and gluten, resulting in a dough that is easier to work with and a loaf with a better crumb and rise.
Used as a dough conditioner to produce and airy and chewy loaf. Banned in the EU and UK for use in bread making.
A convention used by baker’s in which ingredients are expressed as a percentage of the total amount of flour. This allows recipes to be scaled up or down easily. For example, if a recipe calls for 1000g flour, 600g water, 2g yeast and 10g salt, it can be written as 100% flour, 60% water, 0.2% yeast and 1% salt.
A proving basket made from cane, wicker or wood pulp. It is used to support the dough during the final prove.
You can buy these in the shop.
To increase hydration and get a more open crumb it is best to add more water just a little bit at a time. The technical term for this is what the French call called Bassinage. We don’t have an English direct translation for, but it means water that is worked into the dough in small increments during the bulk fermentation.
It is a very traditional technique, but what is really important to remember is that the ” eau de bassinage” ( the water) is removed from the total water in the formula.
So if you have a total of 800g of water in the formula with 50g bassinage they you will mix 750g of the water in initially with the flour then add the 50g in gradually at the later stage during the bulk fermentation stage.
A batard is a loaf shaped like a baguette, but much wider and shorter.
It has tapered ends and is slashed diagonally and baked using exactly the same method as the baguette.
For home bakers one of the things we recommend to students when baking batards, is to bake in something that helps to retain the steam, such as an oblong baker.

Sourdough starters are a symbiotic relationship between lactic acid bacteria and yeast. So you will find different find both yeast and lactic acid bacteria. There are three categories of of lactic acid bacteria, based on the kind of acids that they produce.
In bread making they The LAB (Lactic acid Bacteria) ferment sugars are already in the flour and that have been broken down by enzymes to produce carbon dioxide and acids
These organic acids both flavour the bread and facilitate the biochemical processes that contributes to the enhanced nutritional profiles of sourdough bread. Based upon how they ferment carbohydrates, lactic acid bacteria can be categorised into three main types.
- Homofermentative lactic acid bacteria.
- Heterofermentative lactobacilli
- Facultative Heterofermentative LAB
Facultative Heterofermentative LAB is the kind that can either produce different end products such as lactic acid, acetic acid and carbon dioxide similar to heterofermentative bacteria or only produce lactic acid depending on the type of sugars available for fermentation.

Enzymes extracted or purified from microscopic moulds
The part of a grain that, given the right conditions for germination, would sprout. The germ has a high fat content, and is usually separated out during milling because its presence reduces shelf life in flour. The germ contains vitamin E, minerals and protein. Whole wheat flours contain wheat germ.
A protein in wheat and other cereals needed for the formation of gluten. Gliadin provides extensibility in dough, allowing it to stretch. See also Glutenin.

In sourdough starters you have yeast and lactic acid bacteria. There are three types of lactic acid bacteria, based on the kind of acids that they produce. The LAB ( Lactic acid Bacteria) ferment carbohydrates and produce carbon dioxide and acids.
These produce organic acids that flavour the bread and facilitate the biochemical processes that contributes to the enhanced nutritional profiles of sourdough bread.
Heterofermentative means ‘different’ or mixed end products. They produce both lactic acid, acetic acid and carbon dioxide (CO2) as by-product . They predominantly produce acetic acid, which is the ones that we recognise as vinegary flavour.
See also Homofermentative lactobacilli & Facultative Heterofermentative lactic acid bacteria.

In sourdough starters you will find both yeast and lactic acid bacteria. There are three types of lactic acid bacteria, based on the kind of acids that they produce. The LAB ( Lactic acid Bacteria) ferment carbohydrates and produce carbon dioxide and acids.
These produce organic acids that flavour the bread and facilitate the biochemical processes that contributes to the enhanced nutritional profiles of sourdough bread.
Homofermentative LAB (homo meaning ‘all the same’) refers to the end product of fermentation, which is only, or ‘all’ lactic acid, they also produce carbon dioxide (CO2) as by-product . Lactic acid is the flavour that you might recognise as tasting tangy like yogurt.
For more on bacteria in sourdough see Heterofermentative lactobacilli & Facultative Heterofermentative lactic acid bacteria.

Probiotic bacteria are found mainly in fermented foods, a sourdough starter when it is alive is a probiotic. There are many studies that promoting a positive health image of probiotics in fermented foods such as sauerkraut, yogurt and kefir for example.
Fermented foods contain living microorganisms (bacteria), however there are many questions about the ability of the probiotics to survive and become active when entering the consumer’s gastrointestinal tract. The general consensus is that probiotics, when consumed as part of a fermented food are beneficial.
