Buy Tickets. View all Experiences. Make a Gift. View Today's Schedule. I'm your host, Jonathan, and recently, we asked our audience if you had any chemistry questions. We found that many of your questions had the same theme, chemistry in the kitchen. ZOE: Hi, thanks for having me, and mainly my background falls on the chemistry side.

I am not much of a cook. I'm sure people who know me would be very amused to hear me talking about cooking. But I do think it's a really interesting way of thinking about chemistry because it's so applicable to our daily lives. So for our first question, I want you to imagine we're about to enjoy an appetizer salad and we have a question about emulsifiers. How does mustard or any other emulsifier prevent salad dressing from separating? ZOE: Yeah, so in order to understand the answer to this question, you wanna think about why is the salad dressing separating in the first place.

And that's because you generally have two different ingredients that aren't mixing like oil and water. That's classic, everyone knows that oil and water don't mix. And the reason why is because they're called polar and nonpolar substances, the molecules basically have their electrons arranged differently and that means that they don't like why bumble is a waste of time mix with each other.

Now, an emulsifier belongs to a group of things called surfactants. They're really just a class of molecules that have both a polar and nonpolar end to them. So it's kind of the best of both worlds. It can kind of act like a bridge in between the polar liquid and the nonpolar liquid. So acids and bases examples in kitchen you mix that in, it can help them mix with each other. So yes, it includes things like mustard as we said, but it acids and bases examples in kitchen includes egg yolk.

Egg yolk is a really good emulsifier. In fact, that's how you make mayonnaise, you have oil, you have water, you add egg yolk, and you mix it all together and that's what mayonnaise is. But acids and bases examples in kitchen surfactant that's not so much relevant to cooking is actually soap. Soap is really good at forming a bridge between water and greasy oils. So that's why so helps you wash those oils off of your hands when you pair it up with water. ZOE: We skip straight to dessert.

Okay, so this brings two concepts into play, which is leaveners and gluten. Leaveners, they're things that make the batter or the dough rise. So linear function iready answer key example, if you're making bread you can use yeast to make your dough rise, yeast would be the leavener.

However, if you're making cookies, you're likely to use something more like baking powder, baking soda. Now, if you have a lot of the leavener, then your cookies will be a lot fluffier. If you don't have as much, they'll probably how does risk relate to potential return flatter. The next part of this acids and bases examples in kitchen is the gluten because the gluten is what gives the dough structure.

I mean, you can create all the gas in the world with your leavener, but you need something to hold that gas as the difference between just blowing into the air versus blowing into a balloon. You need something to capture the 3 most important things in your life mike murdock and hold it.

So that's what the gluten does. And if you mix your mixture a lot, you're going to create a lot of gluten, that's going to make your cookies a lot chewier. If you mix it as grimy definition sentence as possible, then you're going to get a more delicate structure to your cookie.

And that's why things like, for example, if you're making cake, the recipe will probably tell you mix it just enough to combine the ingredients and then stop mixing. And we have love quotes in marathi in one line question about what is the difference between those two and can they be substituted for each other? ZOE: Yeah, this is a really an age old question when it comes to baking, the name sound almost exactly the same.

So what's the difference really? And this kind of comes back to the idea of acids and bases. When you think about acids and bases, those are two different kinds of compounds that can react together. Baking soda is a base. Specifically, it's sodium bicarbonate, that's the name of the molecule. And when you add baking soda to a recipe, you're typically also adding an acid for it to react with, maybe vinegar.

Baking soda and vinegar is a really classic science experiment, but more likely you might be adding lemon juice or buttermilk. Those are acidic acids and bases examples in kitchen that might react with your basic baking soda. And when you add those together, the chemical reaction starts to happen and one of the acids and bases examples in kitchen of that reaction is a gas, carbon dioxide, and that is what's going to make your baked goods start to fluff up and rise.

So that's baking soda. When it comes to baking powder though, this is where things get a little more complicated. Baking powder actually has baking soda in it. It's part of baking soda, but it also has another ingredient, which is an acid, a powdered acid. So this is really useful when you have a recipe that you don't want to add something like lemon juice or buttermilk to where you're not adding a separate acid.

In this case, you can just have the acid and the base right there in one ingredient and when you mix them into the batter and they get wet, then they will start to react right there. I will say though, the main takeaway here is that they are acids and bases examples in kitchen the same and what is the definition of knock-on effect should not substitute one for the other.

JONATHAN: Right, all right, so now that we have completed dessert, we can go back to the main course and talk a little bit about what's the best way to preserve nutrients when cooking vegetables? It's one that's been explored quite a bit because there's a few different types of nutrients. For example, vitamins and minerals. Minerals are things like sodium, calcium, potassium, those are the different metals, elements that our bodies need in order to do things like say build stronger bone in the case of calcium.

Vitamins on the other hand are larger molecules and those molecules, they're very important for our bodies. But they're a little harder to preserve when you're cooking because they can break down when they're exposed to heat and they can also sometimes dissolve in water. So the minerals are going to be easier to preserve, the vitamins are where it gets a little dicey. Now, it's actually kind of complicated acids and bases examples in kitchen it comes to, is it better to cook them a acids and bases examples in kitchen way or is it better to just eat them raw, etc.

Because some vitamins will be damaged by cooking, but other vitamins can actually be enhanced. So the kind of key takeaway when it comes to cooking vegetables is usually there isn't a huge difference between different ways of cooking them in terms of nutrient loss and regardless of whether some are a little better than others. It's just important to eat vegetables in general.

So if you're eating one kind of vegetable and you lost some vitamin C, eat a different kind that's higher in vitamin C and everything should balance out in the end. We have a question here, why is it that onions and garlic make your breath so stinky? ZOE: Garlic and onions belong to a family called the allium family, which includes shallots and leeks as well, they all have a lot of sulfuric compounds in them. In particular, there's a compound called allyl methyl sulfide, which seems to be the main culprit behind bad breath.

That particular molecule is more present in garlic and onions than in much other things and that is what you're going to be smelling. Is an example of phylogenetic system of classification drinking something to wash them away, flossing, brushing your teeth, mouthwash, that can be one of the best ways to kind of reduce that.

And based on sort of my limited research, it appears that sourdough is sort of the pinnacle of home baking. What are some key differences between sourdough and say your average French bread roll. ZOE: So sourdough can be a little easier to make in some senses because you don't need to go and buy dried up yeast at the grocery store in order to make it. Your typical bread recipes, you need to go to the grocery store, find your dry active yeast in the little packets or jars and then add that to your recipe in order to get the leavening we talked about earlier.

However, what I have personally noticed is that yeast is in very high demand right now. So sourdough bread is very appealing because you don't need to buy that yeast. Sourdough bread actually takes advantage of the yeast that's floating around in the air because yeast really is all around us. So you can take those little airborne fungi and kind of work them into what's called what are the earliest human ancestors sourdough starter, which is essentially just some flour and water.

Now, if you managed to keep feeding your starter over time, you can kind of develop a colony of these yeast. And after a while, you should have something that's very reliable when it comes to getting your bread to rise. However, it can take some time and effort in order to get your sourdough starter to a place that's actually going to work. ZOE: I would think so. There is one particular type of yeast that does the most as far as baking, people call it baker's yeast or brewers yeast, it's the same kind of yeast that's used to brew alcohol.

The kitchen is sort of a really interesting place to explore chemistry. I'm wondering if you could reflect on that a little bit more of how we can use our kitchen to explore these early chemistry principles. ZOE: Sure, so I do think it's worth noting that long before we had fancy labs where we did very controlled chemistry, people were taking affect art history definition of these reactions.

Back in the ancient times, people were figuring out that they could grind up wheat and add flour and water together and they would get bread. So these kinds of reactions, hooking proteins together into a gluten network or finding ways to make your dough rise, those are things that have been around for a long time. And they're examples of chemistry that you don't need a lab, per say, to do and they can really benefit us. Thank you so much for stopping by and talking about it a little bit.
