This could be for 2 reasons. It might +be that the bacteria completely consumed the gluten of your flour. +On the other hand over time your gluten network automatically +degrades. This is the protease enzyme converting the gluten +network into smaller amino acids the seedling can use as +building blocks for its growth. This process starts to happen +the moment you mix flour and water. The longer your dough sits +the more gluten is broken down. As the gluten holds the +wheat dough together your dough will ultimately tear. + +\begin{figure}[!htb] + \includegraphics[width=1.0\textwidth]{tearing-dough} + \caption{My dough tearing after 24 hours of no activity} + \label{fig:tearing-dough} +\end{figure} + +In the picture~\ref{fig:tearing-dough} I experimented with +using a starter that has not been fed for 30 days at room temperature. +I tried to make a dough directly out of the unfed starter. +Typically after a long period +without feedings your microbes start to sporulate and go +into hibernation mode. This way they can survive for a long +period of time without extra feedings. Adding additional food +will activate them again. In this case the dough did not ferment +fast enough before the protease broke down the gluten. By activating +your microbes they will start to reproduce and increase in quantity +for as long as there is food available. But this process +in my case was not fast enough. After around 24 hours the whole +dough just started to completely tear apart. The whole process was further +accelerated by me using whole wheat flour. Whole wheat +contains more enzymes than white flour. + +To fix this try to make sure that your sourdough starter is lively +and active. Simply apply a couple of more feedings in advance before +making your dough. This way your dough becomes ready to shape +before it has completely broken down. \ No newline at end of file diff --git a/book/troubleshooting/tearing-dough.jpg b/book/troubleshooting/tearing-dough.jpg new file mode 100644 index 0000000..c289baa Binary files /dev/null and b/book/troubleshooting/tearing-dough.jpg differ
