Eating raw sourdough starter might have crossed your mind once or twice. There are a couple of myths surrounding sourdough, so I set out to see if it’s safe to eat a sourdough starter. Then it occurred to me, why would anyone want to eat raw starter anyway? Let’s find out!
Sourdough starter can be eaten raw, but only in small amounts. If you’re going to eat sourdough starter expect to feel bloated if you have lots. If your digestive system is not in a pretty good shape, do not eat raw starter. There is a good chance you will be sick.
A sourdough starter will contain hundreds of fungus and bacteria in a vast and diverse range. But this doesn’t mean that it’s harmful. Sourdough starter has an acidic environment caused by Lactic Acid Bacteria (LAB). These, combined with naturally occurring wild yeasts, cultivate in the starter. LAB and wild yeasts are the driving forces of the leavening process.
Because of this acidic environment it is difficult for harmful bacteria to grow. This means a sourdough starter is relatively safe for consumption. Actually it is believed by scientists that these strains of bacteria and yeast are good for humans to consume.
Sourdough undergoes a long and lengthy fermentation process. During this it produces Lactobacillus bacteria and Saccharomyces yeasts. Many of these variants are also considered as probiotics. Probiotics kill harmful gut bacteria and fungi.
An active starter is still producing gas. And the temperature of the stomach is perfect for fermentation! This means the dough will rise inside a human body! Expect excess gas and a bloated stomach.
If bacteria cannot be killed by the stomach acid, it will cause you discomfort. Bacteria goes through the warm digestive system and breaks down sugars. As it does this, it produces carbon dioxide. This will make you feel bloated.
The bacteria and yeast in the dough will eventually die once baked. The temperature bacteria die is at 60C (140F). Sourdough bread is usually baked at around 230C (450F), that’s plenty hot enough! Given this, baking sourdough will kill off any harmful (and good) bacteria that are present.
When working with potentially harmful bacteria, it is best to follow some basic hygiene practices. They will keep the starter healthy whilst lower the possibility of bacteria passing around the kitchen.
If any of these are seen, do not eat the starter! Especially raw! You will likely get ill. These signal that the starter has harmful bacteria which are not safe to consume.
In conclusion, a sourdough starter can be tasted or even eaten. Just make sure that your stomach is ready for it. Of the bacteria present in sourdough starters, the majority are healthy.
There will be a few bad ones that make it into the dough. The baking stage will kill them off, making the bread perfectly safe for consumption. Yet, too much eating of a raw starter can lead to severe bloating.
