Using dough improvers to assist fermentation

Though not strictly artisan baking, many bread producers improvers to adapt the dough. Here are a few of the common ones, you can pick these up individually or purchase in the form of a bread improver mix, to be added to the dough.

Let's take a look:

Vinegar

Bread made quickly can often include a dash of vinegar to replicate the missing acetic acid that is naturally produced. The benefits of acetic acid is mentioned in ​this article about dough fermentation.

Acetic acid matures the dough which is very good for gas retention, flavour and aroma. Be careful not to add too much though!


Bean flour

Soy is a common additive to bread. It’s use is slightly controversial though, over and unnecessary use can destroy bread properties. Adding a small amount (less than 1%) to the flour improves dough handling, creates more consistently proofed bread and adds a small amount of volume to the bread.


Bean flour aids oxygenation which gives the dough strength initially but over time causes bleaching which takes away flavour and colour from the bread.


Malt flour

You can increase the rate of fermentation by adding cereal or fungal amylases. The most common of these additives in modern bread making is malt powder.

Malt flour increases the activity of the fermentation and the colour of the crust. The result is a better rise, better taste, longer shelf life and a stronger dough to handle.

Malt powder is commonly used in industrial production and increasingly by home bakers. It replicates the organic activity created by long fermentation so is often used in short fermented bread.

It is not a good idea to add malt flour to the dough which is going to endure a long fermentation. A long-lasting development period with additional cereal or fungal amylases exhausts the yeast and leads to the bread over fermenting.

A common trait of over fermenting bread dough is a gummy tasting crumb after baking. A little malt flour added halfway through a long bulk fermentation stage can give the dough a helpful boost.

Many artisans and home bakers still steer clear of adding malt powder as they prefer bread to be made from the minimum amount of ingredients and tend to use long fermentation times.

I use it when making faster bread occasionally, it isn't essential though I can notice an increase in flavour.


Ascorbic acid

This is the most common addition to modern day bread. It's found on pretty much every label in the supermarket bread section. The reason for this is that it is pretty effective!

Ascorbic acid speeds up the mixing process by encouraging more oxygen to be absorbed and it enhances the strength of the gluten. Using this method removes the need for a bulk fermentation period and so makes a “No time dough”.

Breads that use this ingredient benefit from a higher rise, faster mix times, more water absorption and a shorter production time. The ascorbic acid disappears when baking without a trace making the use of it completely harmless.

But…

As there is no bulk fermentation stage when you use ascorbic acid, dough will lack much of its natural flavours created by the traditional fermentation process. Organic acids are often created by supplementing the dough with malt flour and/or other enzymes.

Accelerating the amount of organic acid which is created will produce a more appetising bread flavour and crumb/crust structure.

Using ascorbic acid without other improvers means the natural flavours and aromas of the flour are pretty much lost. The starches in the flour do not break down correctly without a long fermentation period making the product harder to digest.

That said, there is a good reason that ascorbic acid is used in nearly every bread product made commercially. The loss of flavour can be positively traded with an increase in softness, easier dough handling and a faster made bread. 

So really, it's up to you. Here's a link if you want to get some for yourself:



Should I use dough improvers?

I think that you can make fantastic bread without the use of dough improvers so I wouldn't want anyone to think that they are needed to make bread. If you are looking to make bread quickly or make softer rolls or bread you might want to experiment by using some artificial help.

Likewise, if you are looking to improve a recipe, why not test if a dough improver can help?

A recent example that I have used dough improvers was to get my croissants to rise higher and be lighter tasting. To improve my croissant recipe I added some ascorbic acid to the dough which did give them a better rise.

What I wouldn't recommend is using improvers without expecting a particular result. Dough improvers can improve the dough however, they lower its flavour and characteristics that naturally occurring acids bring in organic fermentation.
