yeast and baking powder experiment

Observations Time: What differences do you observe in your breads? You'll need the following materials, included in Magical Microbes's DoughLab, or available at your local grocery (or pantry! As baked, the carbon dioxide bubbles of different sizes (from the different yeast) expand and the ethanol evaporates creating an irregular structure. Many types of bacteria, such as lactobacillus, produce lactic acid as a waste product when they eat, which makes bread and yogurt sour. This process starts immediately. To grow these grains, people settled down and began to farm and build thriving communities. September 20, 2015 - 5:39pm. Many new ingredients, like vitamin C and anti-microbial preservatives, are now often added to bread to allow bakers to use less-expensive grains and to lengthen shelf-life. 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. Yeast is, after all, a rising agent, and most kitchens have a jar or packet of another rising agent tucked away somewhere – baking powder! 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. What Else Can I Try?. The recipes I found used baking powder, yeast, and sourdough starter as the leavening agents. Since I was ultimately going to be making 3 loaves of bread, I decided to quarter the recipes to avoid creating unnecessary waste. Both yeast and baking powder are used to gas-fill the pastry, make it expand and thus make it soft and fluffy. For all three containers, add flour up to the 200ml mark (7/8 cup for each container). The recipes I found used baking powder, yeast, and sourdough starter as the leavening agents. You may find a cake recipe or two that calls for yeast such as Potica or Panettone. 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. So, this process starts in the outermost layer of the bread: the crust. Change ), You are commenting using your Google account. 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. 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. B) Salt: Add a couple more pinches of salt to the top of your flattened dough before baking. There's science behind your favorite treats. Did you notice any difference? If your dough is dry and difficult to mix, add water until all your doughs are the same gooey consistency. 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. How do your independent variables impact your dependent variables? Yeast is activated or woken up by warm water and then the sugar acts as its food. 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. Use the same mixing sticks (or clean spoons) from Step 8 to avoid cross-contamination. Try the same experiment, but this time use about a tablespoon of baking powder instead of yeast, but without the sugar. Both crusts got golden due to the Maillard and caramelization reactions. The type of yeast used for baking is usually Saccharomyces cerevisiae , but it is one of more than 1,000 species of yeast. Today, we call these "flat breads," and they include breads from all over the world, like pita, tortillas, and naan. When the yeast feeds on the sugars, it decomposes the sugars into carbon dioxide and ethanol alcohol. You could also try the same experiment using hotter and colder water. Work out any flour clumps. ), 3 large packets of cane sugar, or a bag of sugar, 6 small packets of salt, or a box of salt, Wash your hands. Add 3 large packets of sugar (1/4 tablespoons total) to container #2, the “Added Sugar” container. Can you explain what caused these differences? 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. Yeast needs sugar to grow and a warm environment. I cultivated my starter from a few simple ingredients, water, and flour, and over time it started to grow. 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. Ever wondered what makes sourdough bread sour? Place a clean glove over the top of the jar such that it covers the top rim. Baking Soda is alkaline and reacts with acids such as vinegar, releasing carbon dioxide ( a gas ) and water. So, once stabilized and added to the flour and water of bread dough, the starter feeds on the sugars converting them into carbon dioxide, ethanol, and acetic and lactic acid. Can you explain the results you find? 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! You’ve probably also got some acid-producing bacteria in there that will give you sourdough. Through your experiments, you’ve learned different ways to make your bread denser or fluffier. Remove the gloves and place each ball of dough into the corresponding tin. Although they look similar, yeast and baking powder can't be swapped in a recipe. In the menu below are links (in blue) to experiments you can do at home. If your dough looks good, you can save the dough you removed in an air-tight container in the fridge and bake it later! Other ingredients (yogurt, baking soda, salt, honey, etc. Did you make this project? Share it with us! Or, try: A) Olive Oil: Smear olive oil onto your baking sheet and over your flattened dough before baking. https://bakerbettie.com/basic-quick-bread-recipe-sweet-or-savory/. Mix the dry ingredients together with a mixing stick (or clean spoon). If the baking powder is fresh, the mixture should produce lots of bubbles. Create electricity from the bacteria living in mud, or make bread while racing yeast! This ensures the same amount of water is poured into each container. You can mix your dough with WARM liquid not hot, as hot liquid will kill the yeast. Bread started out consisting of only 3 ingredients, grain, salt, and water, but today, bread often contains over 30 ingredients in just one loaf! ( Log Out /  One of the reasons bakers knead dough is to uncoil gluten compounds and encourage more linkages between them. 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. Sourdough starter is made using flour and water, and the wild yeast and natural bacteria in the flour start to feed on the sugars and thrive. 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. Knead the dough in your hands until it's a compact ball. ( Log Out /  Baking powder is a chemical ingredient also known as a mixture of sodium bicarbonate and acid salts. One thing I noticed about the sourdough though was that it spread a lot, but I’m pretty sure I didn’t put in enough flour so that’s my bad. Seal up the bag and let it sit at room temperature out of direct sunlight. This variety of yeast in the starter gives the bread its unique flavor as well as contributing to the unpredictable pattern in the rising and bubble structure of sourdough bread. Bonus Experiment: Sourdough (Quick version). Bake the tins together for 20-30 minutes until the top of each loaf is golden-brown (adult supervision required). The baking powder bread tasted slightly egg-like, almost biscuit-like in flavor. 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). However, instead of producing CO2, yeast will produce alcohols through a process called fermentation, making yeast a key player in beer and wine production. Pour the water over the dry ingredients up to the 350ml mark for each container (2/3 cup of water). Use that knowledge to create your own perfect pizza crust. Specifically I was looking at the leavening agents and processes effects on flavor, texture, and color . Once the bread has baked, this is what gives the loaf its airy texture. ): Note: You'll also need a pen and scissors. Try the same experiment, but this time use about a tablespoon of baking powder instead of yeast, and leave out the sugar. When mixed with water, the sodium bicarbonate and acid combine and react to create carbon dioxide. No yeast goes into container #3. Bread-making all over the world continues its various traditions, in addition to enjoying new flavors, ingredients, and techniques. Your ultimate guide to baking with 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. For serious bakers, crust is often the most important part of bread. 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. Overall, the loaves looked and tasted very different, which is not surprising due to the different ingredients and processes that were involved in making the bread. Observation Time: Which glove inflated the fastest? Which ingredient takes longer to fill up the balloon? In these instructions, container #1 is the “Control,” container #2 has “Added Sugar,” and container #3 has “No Yeast.”. Most bread recipes that use vinegar call for no more than 1 teaspoon per 1- to 2-pound loaf. To keep the experiment controlled, I decided to use simple similar bread recipes that the only major difference between was the leavening agent. I decided to make a sourdough starter during this quarantine because sourdough bread has always been my favorite, and we weren’t going to the store often. When a liquid is added to a batter containing baking powder, the tartaric acid (cream of tartar) and the sodium bicarbonate(baking soda) dissolve in the liquid and thus have more freedom to move around and react. Add 3 small spoonfuls of yeast (3/4 teaspoon total) to container #1 (the “Control”) and Container #2 (the one with “Added Sugar”). ( Log Out /  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! Keep your mixing sticks in their corresponding containers. In terms of texture though, this bread overall had the largest irregular air bubbles, and a chewy texture in the bread, a crust also formed on the outside of the bread that was crunchy and slightly chewy. Test baking powder by mixing 1 teaspoon of baking powder with 1/3 cup hot water. https://www.stevespanglerscience.com/lab/experiments/flame-light-relight They are used to make the dough rise as both produce carbon dioxide gas that stays as bubbles in the dough. This process of eating food and releasing waste is called “respiration.” Interestingly, even without oxygen, yeast continue to respire. Mix the dry ingredients together with a … Baking powder crumpet experiment, raising problem. 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. Beat together sugar and egg until fluffy with an electric mixer in the bowl. It’s time to explore the science of yeast! In the case of the yeasted bread, the dough was kneaded to create stronger gluten strands. https://www.rookieparenting.com/the-science-of-bread-baking-kids-experiment Try adding a bit of yogurt with active cultures to your dough to see if you can grow lactobacillus and make tasty sourdough bread! About 30,000 years ago, humans began making bread. I even named my starter Beast because all living things deserve a name! Long-term care: Store your starter in the fridge, and feed by mixing in 7 scant tablespoons of flour and 4 tablespoons of water once a week. Add room temperature water up to the 350ml mark (1/2 cup + 2 tablespoons). 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). Be sure to use a new stick (or spoon) for each container so that you don’t cross-contaminate the mixtures. After kneading for a few minutes, squish the dough back into the container, and flatten the top. About: We make fun and educational STEM kits that let you play with microbes. 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. Pour quickly so you've finished pouring before the water starts to seep into the flour. Wheat flour contains a protein, called gluten, which adds to the stretchiness of dough and the chewiness of bread. Wash your hands between each container to prevent contamination. The best part of this scientific investigation... the eruptions! The typically used active dry yeast, or baker’s yeast, that you can buy in the supermarket exclusively consists of one type of yeast: Saccharomyces cerevisiae. Make sure to talk to an adult (your parents, teacher or an older friend) before you begin any of these experiments, as they will be able to help you get the tools you need to conduct the experiments. As mentioned, gluten is a protein, so when the dough is pulled and kneaded the strands of the protein stretch to become longer and stronger, this accounts for a chewier texture in the yeasted bread. 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. Add 2 small packets of salt (3/4 teaspoons total) to each container. Yeast & Baking Lessons We want you to be successful in baking! You can substitute baking powder for yeast but the taste and texture will not be the same. Put your glove back on the container. This explains the large irregular bubbles that were present in the dough. You’ve created seitan, a food enjoyed all around the world, commonly with soy sauce, ginger, and garlic. 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. 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. However, the textures of all of the pieces of bread were very different. 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. 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. Change ), You are commenting using your Facebook account. This causes dough to become stretchy and gooey. A fun science project for kids that’s with household, everyday materials. Otherwise, continue repeating step 1 until your mixture doubles in 6 hours. The happier the yeast, the faster their respiration rate, and the faster the gloves will inflate! It derives its carbon dioxide gas through a biological process of fermentation. 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. Yeast converts sugar and starch (from the sugar and flour in the bread mix) into carbon dioxide and ethanol. On the other hand, baking powder is made with chemical compounds such as sodium bicarbonate. 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. In sourdough, these bacteria typically outnumber yeast 100-to-1! All containers should get the same temperature water. Optional messy-but-fun step: With washed hands, scoop up the dough and knead it (fold it in on itself repeatedly). Baking powder is made of a combination of an acid, a base, and a filler all in powdered form. As far as the procedures go though, I really just followed the recipes as written. https://recipes.howstuffworks.com/tools-and-techniques/baking-powder.htm, https://www.lefoodist.com/guides/cooking-classes-paris/cookingparis146.html, https://www.thekitchn.com/the-science-behind-yeast-and-how-it-makes-bread-rise-226483, https://www.discovermagazine.com/planet-earth/the-biology-of-sourdough, https://slate.com/culture/2012/11/why-does-steam-make-bread-light-and-crusty-it-slows-down-the-cooking-process.html. Our Inspiration. 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. Yeast is a living organism that survives by consuming simple sugars, such as what can be found in flour and granulated sugar. Manipulating the baking chemistry this way produces bread that rises higher and has a more refined texture. 4. Baking powder is activated by a combination of heat and moisture. The way bread bakes is through all the moisture being drawn out of the loaf. Soda bread, on the other hand, uses baking soda to create volume, reacting with an acid to form carbon dioxide and breathe life into the loaf. So, although the surface dried out, the gluten proteins did not coagulate and create a crust. However, since the sourdough was kneaded less, less gluten developed, creating a more crunchy than chewy crust. In this Yeast and Sugar Science Fair Project, we’ll watch yeast feed on sugar to fill a balloon with air. Gluten proteins expand and become tangled up with other straggly gluten proteins nearby. With the addition of warm water, yeast “activate,” meaning they begin to swim, eat, and multiply. Play with it, and notice that the ball is comprised of tightly-woven clumps of gluten. Determine which “independent” variables you’d like to change and which “dependent” variables you’d like to measure. Change ). This strengthens the gluten network and gives bread a more uniform, chewy texture. There are hundreds of ways to make dessert breads and cakes. Use your starter from step 3.3 with any recipe you please! Store your fledgling starter (dough) in a warm place. How to Test Baking Powder . Yeast is actually a type of fungus related to mushrooms. However, in the oven, the heat causes the carbon dioxide bubbles to expand and spread apart. (Save the gloves for your yeast! ... we recommend testing sourdough as a chemistry experiment. This resulted in the airiness and overly fairly uniform bubbly nature of the bread. Either way though, what made the loaves of bread so different? Add milk, oil, vanilla and baking powder and beat until well mixed. Baking Soda vs Baking Powder go head to head in this epic battle between two kitchen staples in this kid approved science experiment. 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. But these two simple looking white powders can cause BIG reactions. 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. Using yeast is rather inconvenient - it can be dead already or if the yeast is submerged in too hot water it can die and also waiting for yeast to work to let it gas-fill the pastry before baking … (No wonder yeast means "bubbles" in old English and was dubbed saccharomyces, or “sugar fungus” in Latin!) Be sure to use warm or hot water; cold water will not work for this test. Change ), You are commenting using your Twitter account. Find out the difference between baking powder vs. yeast and when to use each. Carbon dioxide from yeast fills thousands of balloonlike bubbles in the dough. Key Difference – Baking Powder vs Yeast There seems to be a lot of confusion over the difference between yeast and baking powder. Once you see bubbling in the mixture and the glove inflating, your yeast are replicating! Why? 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. Now, get ready to bake by turning the oven to 350 F (adult supervision required). 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. Yeast is far much healthier than baking powder. ), Label your three clear containers. Since both the yeasted and the sourdough breads were kneaded, and the yeasted had additional kneading time, they both got a crunchy chewy crust due to the gluten. The cold water will dissolve the starch in the dough, but it won’t dissolve the gluten. 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 this experiment, the gas fills up the gloves. Once your mixture looks foamy, repeat step 1, and if your mixture doubles in volume in about 6 hours, it's time to use. For a crispier crust, rub the top of your dough with oil or water. Open the yeast packet using a pair of scissors. 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. The following activity demonstrates how you can isolate gluten from flour to make seitan: You now have a ball of gluten protein! Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. Though baking soda, baking powder, and yeast all result in the production of carbon dioxide gas and leaven dough, there are many differences. Baking powder and yeast are two of the most commonly used leavening agents in baked foods. Repeat steps 1-3 for the different breads you’ve made and/or breads from the store. You’ll need them again later. Mix until the consistency is smooth. Baking soda experiments or activities are a great, safe and easy way to introduce the concept of a chemical reaction to children. Record what percentage of the bread is covered by mold, and see if the mold coverage follows an exponential growth curve. C) Sweeteners: Sugar, bananas, apple sauce, sweetened chocolate, and even carrots are common ingredients that add sweetness! They may look similar. To keep the experiment controlled, I decided to use simple similar bread recipes that the only major difference between was the leavening agent. A leavener is what the dough needs to begin to rise. They may be used for the same purpose but they are different from each other. https://www.firstforwomen.com/posts/food-recipes/how-to-replace-yeast Once you let the dough rest, the yeast go to work! Their names may sound similar. In the presence of oxygen, this fungus munches up sugars and produces carbon dioxide, or CO2, making bubbles in liquid or dough. Use a thermometer to measure the temperature of the water. Yummm! Repeat Step 1 daily until your starter is bubbling and yeasty or fruity smelling. 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. A leavener can be baking soda, baking powder or yeast. Overall this experiment did not disappoint. Gently knock the jars down on the table a few times to level the mix.
