Food Porn Fact Check #2

As much as I love the food porn, someone needs to set the record right about the use of yeast in the show.

There are two key parts of episode 4 of King of Baking that I want to address:
1. you can smell the sweetness and sourness of yeast fermentation.
2. dry yeast and live yeast result in different kinds of bread.

Part 1:

A super-smeller can smell the sweetness and sourness of yeast fermentation

I don’t have a super nose, so I can’t confirm if you can really smell anything. The point of using yeast in bread making is as a leavening agent. Before they discovered yeast, bread used to be a hard untasty thing, sometimes used as plates.

As the yeast grows in the dough, it produces carbon dioxide as it breaks down and feeds on the sugars, creating little pockets of air. These air pockets causes the dough to “rise”. Another side product of yeast growing in the dough is that they produce small amounts of alcohol. After baking, there is no alcohol left since it wasn’t much to begin with.

Summary:
It is possible for the yeast to release small amounts of simple sugars in the fermentation process. I don’t really know what the sour smell is.

Part 2.


I don’t know if anyone noticed this, but at around 5 sec, you see the different doughs, and dough #3 looks considerably larger/puffier. The other three look like they need a bit more time.

Anyway, if you didn’t watch the video, Il Jung claims that the dough that Tak Gu is smelling in the factory is different than the dough he smelled in the morning at home. He says it’s because they used live yeast at home, and dry yeast in the factory.

The facts:
There are actually two types of dry yeast commonly available. There is dry active yeast, and then there is instant yeast.

You can get live yeast, but it is highly perishable (1 week). For this reason, I rarely see it in stores.

Dry yeast and live yeast are pretty much the same yeast, so they don’t give you different flavors. If you want something different, like sourdough bread, you need a different type of yeast.

So really, the differences in the 4 types of dough vs the bread made by Il Jung cannot be due to dry yeast vs live yeast. The amount of time allowed for fermentation might have a subtle effect on the taste of the bread, but it’s mostly to know that the bread has risen enough.

One last thing: wikipedia says that most factories use live yeast, and it’s the homebakers that use dry yeast. This makes a little more sense to me since the high volume of bread making in a factory allows them to use large amounts of yeast quickly.

You can read allrecipes.com for more information about the different types of yeast.

    I really like your food porn fact check entries! Very detailed accounts of what seem doable and what doesn’t. Thanks for the research & clarification 🙂

    live yeast and dry yeast could have a different smell since one is more “fresh” and one is dried. THe amount of proofing time is probably different and im not sure but companies could use dry yeast because of the longer shelf life

    and i would just like to say that this is just a drama, there really is no reason to “rant” but i guess if you have a blog you could “rant” 😛
    LOL and i am no way a professional baker
