Dough was left out in the open to "rise," as yeast (which naturally live on grains and other foods) would munch up sugars and release gas bubbles into the dough. However, since the sourdough was kneaded less, less gluten developed, creating a more crunchy than chewy crust. Carbon dioxide is what is responsible for making breads rise. Nutrients that are easily digested are called “bioavailable.” Foods that have a lot of “bioavailable” nutrients, like bread and milk, often mold or sour quickly, which is why many store-bought breads contain preservatives and other chemicals to prevent microbes from growing on them. Pour the water over the dry ingredients up to the 350ml mark for each container (2/3 cup of water). In the menu below are links (in blue) to experiments you can do at home. Generally speaking if the dough does not have these characteristics yeast alone works and does not run the risk of adding "baking powder flavor" to the product, and if the quickbread has a strong enough flavor due to other ingredients then the baking powder alone is sufficient and there is no need for a fermentation step. Mix until the consistency is smooth. Did you make this project? To keep the experiment controlled, I decided to use simple similar bread recipes that the only major difference between was the leavening agent. Add milk, oil, vanilla and baking powder and beat until well mixed. Overall this experiment did not disappoint. Today, we call these "flat breads," and they include breads from all over the world, like pita, tortillas, and naan. However, since this process happens instantaneously, the small carbon dioxide bubbles will deflate if left out, which is why in baking you typically add the liquids to the dry ingredients last to prevent the carbon dioxide from escaping. However, since the dough has gluten developed, the carbon dioxide doesn’t merely escape the bread into the surroundings, it gets trapped in between the gluten strands causing the dough to rise. What differences do you see between the breads? So, if you want to see how I made the loaves or want to make them for yourself, I will link the full recipes below. As moisture evaporates, the crust starts to harden as it dries out. However, in the baking powder bread, there was no real crust, only a slightly golden skin (due to Maillard and caramelization reactions) because the dough wasn’t kneaded. Unlike store-bought yeast, the wild yeast in a sourdough starter is many different types of yeast, such as Hanensula anomala, Cndida tropicalis, and many others. “Respiration” describes the process of munching up food and releasing waste. Which ingredient takes longer to fill up the balloon? But these two simple looking white powders can cause BIG reactions. Remove the gloves and place each ball of dough into the corresponding tin. Due to the unpredictable nature of the different wild yeast varieties in sourdough starter, sourdough often takes a long time (up to 18 hours) to properly rise because the yeast has to convert all the sugar to carbon dioxide. You can substitute baking powder for yeast but the taste and texture will not be the same. Ever wondered what makes sourdough bread sour? Add flour and mix. Other ingredients (yogurt, baking soda, salt, honey, etc. I even named my starter Beast because all living things deserve a name! In the presence of oxygen, this fungus munches up sugars and produces carbon dioxide, or CO2, making bubbles in liquid or dough. This process of eating food and releasing waste is called “respiration.” Interestingly, even without oxygen, yeast continue to respire. A fun science project for kids that’s with household, everyday materials. The sourdough, on the other hand, had a distinct sour flavor in the bread, similar to what you’d expect from a sourdough. Google didn't help. We encourage you to experiment with the common additives below to find your own perfect recipe: A) Vegetable Oil, to make the bread/cake moister, B) Eggs, to add to “fluffiness” and moisture and to help bind ingredients. One of the reasons bakers knead dough is to uncoil gluten compounds and encourage more linkages between them. The recipes I found used baking powder, yeast, and sourdough starter as the leavening agents. Beat together sugar and egg until fluffy with an electric mixer in the bowl. However, the yeasted bread had a slightly yeasty flavor, but a distinct bread taste. Early bread was made of a grainy paste and was dense and flat, making it a perfect high-energy food that could be carried and stored. Be sure to use warm or hot water; cold water will not work for this test. About 30,000 years ago, humans began making bread. Yeast is actually a type of fungus related to mushrooms. Can you explain what caused these differences? About: We make fun and educational STEM kits that let you play with microbes. Yeast is a living single celled organism commonly used in baking. You can mix your dough with WARM liquid not hot, as hot liquid will kill the yeast. Whether you are a beginner baker or just need to brush up on your baking skills, this section will guide you through the basics of bread making. The baking powder bread tasted slightly egg-like, almost biscuit-like in flavor. Seal up the bag and let it sit at room temperature out of direct sunlight. Yeast is a type of leavener (baking soda and baking powder can also be used as leaveners). Baking powder and yeast are two of the most commonly used leavening agents in baked foods. Use your starter from step 3.3 with any recipe you please! In a clean plastic sandwich bag, place one small (2” x 2”) piece of damp paper towel. Populations boomed with these energy-rich, storable foods. ): Note: You'll also need a pen and scissors. The way bread bakes is through all the moisture being drawn out of the loaf. Open the yeast packet using a pair of scissors. In a clean jar, add flour up to the 200ml mark (3/4 cup + 1 tablespoon). Specifically I was looking at the leavening agents and processes effects on flavor, texture, and color . A leavener can be baking soda, baking powder or yeast. Both yeast (specifically, baker’s yeast) and baking powder are leavening agents. Change ), You are commenting using your Twitter account. If your dough is dry and difficult to mix, add water until all your doughs are the same gooey consistency. Once you see bubbling in the mixture and the glove inflating, your yeast are replicating! ), Label your three clear containers. ), 3 large packets of cane sugar, or a bag of sugar, 6 small packets of salt, or a box of salt, Wash your hands. Yeast takes a few hours to work because it takes time for the yeast organisms to consume the sugars and produce carbon dioxide that is necessary for the bread to rise. ( Log Out /  Just like the volcano experiment with baking soda and vinegar, you can achieve a similar reaction with baking powder and water (only it will take more baking powder to get the same effect). For this experiment, you'll want a supply of whole wheat flour. Although they look similar, yeast and baking powder can't be swapped in a recipe. Both yeast and baking powder are used to gas-fill the pastry, make it expand and thus make it soft and fluffy. For serious bakers, crust is often the most important part of bread. Add 3 small spoonfuls of yeast (3/4 teaspoon total) to container #1 (the “Control”) and Container #2 (the one with “Added Sugar”). If you see weird colors, fuzzy patches, or anything else that looks like mold, you’ve caught some other moldy microbes, and you’ll need to start your sourdough starter over. There are three types of yeast; fresh yeast, instant yeast and active dry yeast Fresh yeast: used by profestional baker. Wash your hands between each container to prevent contamination. Add 3 small spoonfuls of yeast (3/4 teaspoon total) to container #1 (the “Control”) and Container #2 (the one with “Added Sugar”). I saw video's and posts about how easy it is to brew your own mead. Let the loaves cool for a few minutes, then enjoy the results of your experiment! It derives its carbon dioxide gas through a biological process of fermentation. Continue rinsing and gently massaging the dough until the water is no longer milky-looking. How do your independent variables impact your dependent variables? I was left with three rather tasty different types of bread, and that’s all due to chemistry of the ingredients going together. I cultivated my starter from a few simple ingredients, water, and flour, and over time it started to grow. ... we recommend testing sourdough as a chemistry experiment. So, when wet, a neutralization reaction occurs between the acid and base in baking powder, forming water, potassium sodium tartrate (a salt), and carbon dioxide. To keep the experiment controlled, I decided to use simple similar bread recipes that the only major difference between was the leavening agent. Advice that I incorporated in this crumpet recipe that uses yeast and baking powder was; add vinegar, add oil, incorporate dry baking powder into batter by sifting it in and whisking quickly. Once the bread has baked, this is what gives the loaf its airy texture. Try tearing those clumps apart to see how strong gluten strands can be. Once you let the dough rest, the yeast go to work! B) Salt: Add a couple more pinches of salt to the top of your flattened dough before baking. How does yeast work: Results. Yeast is a living organism that survives by consuming simple sugars, such as what can be found in flour and granulated sugar. Now that you’ve set up your microbe bait, it’s time to wait. Their names may sound similar. This process starts immediately. https://www.firstforwomen.com/posts/food-recipes/how-to-replace-yeast Carbon dioxide from yeast fills thousands of balloonlike bubbles in the dough. During this quarantine, I’ve had a lot of time to do things that I didn’t have time for before, so one of the things I took up was bread making. When the yeast feeds on the sugars, it decomposes the sugars into carbon dioxide and ethanol alcohol. Combine the dry ingredients, all-purpose flour, whole-wheat flour, baking powder and salt, in the large bowl and blend with a wooden spoon until thoroughly mixed. This ensures the same amount of water is poured into each container. Mix the dry ingredients together with a … https://www.stevespanglerscience.com/lab/experiments/flame-light-relight Your ultimate guide to baking with yeast! As far as the procedures go though, I really just followed the recipes as written. Observation Time: Which glove inflated the fastest? The recipes I found used baking powder, yeast, and sourdough starter as the leavening agents. Cup the dough in your hands, and run cold water over it continuously. However, since the batter wasn’t kneaded like a typical bread, the protein strands of gluten don’t develop as much, so carbon dioxide bubbles don’t get trapped in between the protein strands as much, and will exit the batter more readily. The active ingredient in baking powder, sodium bicarbonate or baking soda makes an excellent loaf of bread if you can’t get your hands on any yeast. Try the same experiment, but this time use about a tablespoon of baking powder instead of yeast, but without the sugar. Bread started out consisting of only 3 ingredients, grain, salt, and water, but today, bread often contains over 30 ingredients in just one loaf! 4. Repeat steps 1-3 for the different breads you’ve made and/or breads from the store. Baking powder is made of a combination of an acid, a base, and a filler all in powdered form. Wheat flour contains a protein, called gluten, which adds to the stretchiness of dough and the chewiness of bread. If you are having trouble buying yeast, ... Cakes are generally best if you use baking powder or soda to rise because they are tender and light. Baking soda is a simple base and therefore needs to be combined with an acid of some sort, such as yogurt, lemon, or vinegar, in order to become activated. C) Sweeteners: Sugar, bananas, apple sauce, sweetened chocolate, and even carrots are common ingredients that add sweetness! According to Webster’s New World Dictionary, the word “leaven” comes from the Latin word “levare,” a word that means “lift up, to make light and rise.” Yeast gets energy from its favorite source of food in the form of sugar. In terms of texture, although it was airy, the air bubbles were relatively small, the texture was more similar to the density of a cake than anything else, and it had more of thin skin on the outside than a crust. September 20, 2015 - 5:39pm. The following is a simple experiment that will show you which breads have the most “bioavailable” nutrients and the impacts of preservatives: Check the bags daily to see which pieces of bread are molding. Optional messy-but-fun step: With washed hands, scoop up the dough and knead it (fold it in on itself repeatedly). However, the yeast in sourdough starter is actually greatly outnumbered by lactobacilli, also known as lactic acid bacteria. If you’re a fan of tough, crunchy crusts, here are some tips: A) Cut 1/2-inch deep slits into the top of your dough before baking. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. Now that your culture is alive and well, continue to remove half and mix 7 scant tablespoons of flour and 4 tablespoons of water into your container every. To grow these grains, people settled down and began to farm and build thriving communities. For microbes, some foods are easier to digest than others. For a crispier crust, rub the top of your dough with oil or water. Preheat oven to 350 degrees. Now, repeat step 1 one last time, and once your mixture is doubled in size and actively bubbling (a few hours), take what you need to use in your sourdough recipe of choice, and place the remainder in the fridge. After playing with your ball, knead it back together, and pop it in the oven at 450 degrees F for 15-20 minutes (with adult supervision). In the bottle with the yeast and warm water nothing happens. As baked, the carbon dioxide bubbles of different sizes (from the different yeast) expand and the ethanol evaporates creating an irregular structure. Naturally occurring yeast are probably starting to eat and replicate, though it may take time to see any activity. In terms of texture, the bread was airy, with mostly small air bubbles and a few large bubbles, and a soft chewy texture in the bread, a crust also formed on the outside which was crunchy and slightly chewy. Either way though, what made the loaves of bread so different? In a container, mix 250 ml (1 cup + 1 tablespoon) of high-gluten flour with 150ml (1/2 cup + 2 tablespoons) of tap water. Once your mixture looks foamy, repeat step 1, and if your mixture doubles in volume in about 6 hours, it's time to use. With DoughLab (or the equivalent components from the store), you can design your own delicious bread experiments and learn about yeast! Why might it be stretchy? There are hundreds of ways to make dessert breads and cakes. However, in the oven, the heat causes the carbon dioxide bubbles to expand and spread apart. Alternatively, shape your own foil packets (caution: your dough might ooze at the seams if you try this, so pinch the corners tight)! This drives down pH (to more acidic) and gives the sour taste to sourdough bread. A leavener is what the dough needs to begin to rise. Yet baker’s yeast and chemical leavening agents such as baking powder or baking soda are not the only ways to bake bread, and in fact are relatively recent developments in the world of baking. Use the same mixing sticks (or clean spoons) from Step 8 to avoid cross-contamination. You’ve probably also got some acid-producing bacteria in there that will give you sourdough. If your dough looks good, you can save the dough you removed in an air-tight container in the fridge and bake it later! Bake the tins together for 20-30 minutes until the top of each loaf is golden-brown (adult supervision required). Now, get ready to bake by turning the oven to 350 F (adult supervision required). To design your own bread experiments, use the “Scientific Method": Once you’ve started your experiment, collect and analyze your data: Before you begin, plan your experiment! I combined Yeast with baking powder Hey everyone im a beginning brewer trying out a new hobby. Yeast converts sugar and starch (from the sugar and flour in the bread mix) into carbon dioxide and ethanol. Gluten proteins expand and become tangled up with other straggly gluten proteins nearby. In the case of the yeasted bread, the dough was kneaded to create stronger gluten strands. In this experiment, the gas fills up the gloves. No yeast goes into container #3. You could also try the same experiment using hotter and colder water. Baking Soda vs Baking Powder go head to head in this epic battle between two kitchen staples in this kid approved science experiment. Baking powder crumpet experiment, raising problem. Key Difference – Baking Powder vs Yeast There seems to be a lot of confusion over the difference between yeast and baking powder. https://www.rookieparenting.com/the-science-of-bread-baking-kids-experiment Baking powder is a chemical ingredient also known as a mixture of sodium bicarbonate and acid salts. Is there is a difference in bubble size or consistency in the different doughs? Baking soda experiments or activities are a great, safe and easy way to introduce the concept of a chemical reaction to children. This strengthens the gluten network and gives bread a more uniform, chewy texture. Be sure to use a new stick (or spoon) for each container so that you don’t cross-contaminate the mixtures. You'll need the following materials, included in Magical Microbes's DoughLab, or available at your local grocery (or pantry! When mixed with water, the sodium bicarbonate and acid combine and react to create carbon dioxide. Change ), You are commenting using your Google account. When you're ready to use your starter, take it out of the fridge, and return to Step 2, "Activate your Starter.". However, the textures of all of the pieces of bread were very different. Or, try: A) Olive Oil: Smear olive oil onto your baking sheet and over your flattened dough before baking. Since I was ultimately going to be making 3 loaves of bread, I decided to quarter the recipes to avoid creating unnecessary waste. Gently knock the jars down on the table a few times to level the mix. Work out any flour clumps. In sourdough, these bacteria typically outnumber yeast 100-to-1! B) Rub water or oil over the top of your dough before baking. Roughly 12,000 years ago, people living in modern-day Iraq first domesticated wheat and barley, leading to a massive rise in bread consumption during a period called the "Agricultural Revolution." To make this process faster, people would add pieces of old dough, mashed grapes, or beer foam, which are all full of yeast. Although some of the recipes took time, they don’t require you to have incredible baking skills, so don’t be afraid to try your hand at making bread of your own! Change ). All over the world, grains, like wheat, barley, rice, and maize started cropping up, due to humans’ careful selection of nature’s biggest and best grains. In the case of the baking powder bread, the liquids were added last and not over-mixed to prevent the carbon dioxide bubbles from escaping. A leavening agent is any substance that incorporates gas bubbles into the dough, causing it to lighten, soften, rise and take on what is usually referred to as a “fluffy” texture. Knead the dough in your hands until it's a compact ball. Mark the side and bottom of the foil pans with “1”, “2,” and “3”, by indenting them with your finger or by using a pen. Level off each spoonful (1/4 teaspoon) of yeast before adding it to your container. The addition of water also allows the straggly glutenin and gliadin proteins to bond together to form gluten. The yeast and sugar produce a gas (carbon dioxide). It’s time to explore the science of yeast! Watching yeast respire involves putting gloves on top of your dough containers to capture your yeast's waste CO2 and seeing how fast this CO2 inflates the gloves. After kneading for a few minutes, squish the dough back into the container, and flatten the top. Share it with us! Observations Time: What differences do you observe in your breads? So, although the surface dried out, the gluten proteins did not coagulate and create a crust. Since the bread is also kneaded, as explained this creates stronger and longer gluten chains, trapping the carbon dioxide in the bread, also creating the chewy texture. In this Yeast and Sugar Science Fair Project, we’ll watch yeast feed on sugar to fill a balloon with air. Yeast and baking powder are mainly used for culinary purposes as leavening agents. Both crusts got golden due to the Maillard and caramelization reactions. Typically, baking powder consists of cream of tartar as the acid, baking soda as the base, and cornstarch as a filler to separate the particles of acid and base. The type of yeast used for baking is usually Saccharomyces cerevisiae , but it is one of more than 1,000 species of yeast. Add 3 large packets of sugar (1/4 tablespoons total) to container #2, the “Added Sugar” container. Store your fledgling starter (dough) in a warm place. For this experiment, I decided to try making bread with three different methods in order to prove why they are different based on chemistry. Otherwise, continue repeating step 1 until your mixture doubles in 6 hours. The chemicals undergo an acid-base reaction to produce carbon dioxide gas. Did you notice any difference? While the yeast feeds on the sugars in the flour creating carbon dioxide and ethanol alcohol, the lactobacilli also feeds on the sugars and converts the sugars to lactic and acetic acid as well. Baking Soda is alkaline and reacts with acids such as vinegar, releasing carbon dioxide ( a gas ) and water. Add room temperature water up to the 350ml mark (1/2 cup + 2 tablespoons). You’ll need them again later. (Save the gloves for your yeast! Yeast prefer warm conditions which is why warm water is recommended. This process is aided by the gluten built up in the bread because gluten is a protein, so at higher temperatures it begins to coagulate and turn into a semisolid or solid-state, giving the crust it’s characteristic chew and crunch. Use that knowledge to create your own perfect pizza crust. This resulted in the airiness of the baking powder bread, but also explains why this bread was more dense and cake -like than the other breads. Think about taste, texture, density, color, etc. Use a thermometer to measure the temperature of the water. Add 2 small packets of salt (3/4 teaspoons total) to each container. As the crust gets hotter and hotter, caramelization (when sugars oxidize) and the Maillard reaction (sugars reacting with amino acids at higher temperatures) occur, creating the distinct color and toasty flavor of the crust. Let the containers rest at room temperature (out of direct sunlight) for 30-45 minutes, or until the dough has reached the top of the container. Before you start, here's the skinny on saccharomyces: Yeast,a single-celled fungus that belongs to the same kingdom as mushrooms,is one of the most common microbes in the world. We ’ ll watch yeast feed on sugar to fill up the rest. Simple ingredients, water, yeast, the faster the gloves and place each ball of into.
