They take on the role of scientists and in the process they learn to act as one. Some cheese is not even fermented; examples are queso blanko and gjetost, which are made with heat and acid, and a variety of cheeses are prepared with rennet, but without bacteria. Mold will grow quicker on white bread than it will grow on rye or plain brown wheat bread. Discard Fresh Cheese, Soft Cheese and Processed Cheese Which Is Moldy If mold should grow in these cheeses, the mycotoxins could penetrate farther. The final result, ready to display at the science fair looked like this: The left side of the board contained the question, hypothesis, and research information: The right side of the board contained the results via photos and conclusion: The center of the board contained the title, materials, procedure, and data graph: Overall, the science fair was a big success. Homemade bread molds faster than store-bought bread because it's harder to control its acidity levels and may contain fewer preservatives. It is part of a group of living organisms that are very common and serve an important role in the environment.
When you think of dairy foods, you think most of these require refrigeration. Background Research Studies show that fruit molds faster in room temperature than when in the fridge. Mold is formed by microscopic creatures belonging to the Fungi Kingdom. Preservatives in Bread Preservatives generally increase the acidity of bread so that it molds less quickly. Fruits also have the preservative sugar but it occurs naturally. The independent variable is the one that is changed in the experiment. This is done by running thick needles through it so oxygen can get into the interior.
With these kits, you can take a closer look at why bread, cheese and fruit grow mold, how producers set an expiration date, and perform more experiments on food samples using our. I wonder if you could propose a third method of experimenting the Hypothesis above. This kind of mold is not bad for you, and is purchased like that. If you have further questions please ask. It is used to make comparisons as to what changed or possibly caused the change. Check and observe the samples daily. Some people think that cheese is moldy milk, but it is not.
After 5 to 10 days, you should notice some fuzzy white, black, orange or green spots on the bread. If you did an experiment measuring which type of bread molds the fastest and put one slice in the fridge and one in a cabinet, the slice in the cabinet would mold faster because it is in a warmer and darker environment. Marianne Luke has been writing professionally since 2005. Also, considering experiments, we are planning to run the experiments more than one time, the first run will be in the room temperature while the second one should be in plastic sealable bags placed also in room temperature. But, now we know that some of these molds can produce poisons called mycotoxins which become part of the food and are not destroyed by cooking. Breads such as sourdough are high in acidity and, based on acidity alone, would mold less quickly than white or multigrain.
That is why the mold grew faster on the bread. You have selected an interesting project for a science fair. Which is the first to mold? Mold needs a few factors to grow 1 high humidity 2 warm temperatures 3 food source If you were to keep humidity and temperature constant, I would say that wheat bread would grow mold faster. The same goes for any cheese that's shredded, crumbled or sliced. Dear Ms Hess Thank you very much for your reply.
That is why if someone buys food containing lots of sugar and salt it lasts longer. But, if you do not agree than I would appreciate if you could suggest something else to measured on the 3rd run We would like to extend our deepest thank for your assistance on this project. . Plus, it probably has a taste because it is organic matter. Each trial lasted a week. My 10 year old recently completed the following project for his 5th grade science fair. Which Cheese Molds The Fastest? I would be a good idea to make each piece of cheese about the same size and make the estimates every day.
But it is not necessary to use mold. I will take a slice of each cheese and place on a plate. When mold spores land on a piece of bread, they immediately start feeding and spread, forming velvety green patches. The cheeses most resilient against mold are hard cheeses, such as Parmesan, which last up to 10 months. They began to shrivel up and lost their light and also formed a whitish-blue mold. Once opened, wrap the cheese tightly in waxed paper or plastic wrap and keep refrigerated. Milk is the fastest when it comes to molding because it has these building compounds that triggers fast decomposition.
Food in refrigerators seems to keep longer than food left out in the sun. A special thanks to for their science fair ideas. Molds are microscopic organisms that have thread-like roots that burrow into the foods they grow on. Some have mold that grows over the surface, usually a white mold such as what appears on brie. Some of these have mold on them, but the ones that do mostly have either white penicillium mold as on brie or blue or green penicillium mold as on blue cheese.
The fastest way to grow mold on bread is to cut an orange in half, because of the sodium the mold will grow more and faster. When WholeWheat bread was left to mold, it grew an average of 60. Molds are fungi and so are mushrooms, so I think they would have a taste. Record And Analyze Data: After a week we looked at all our results. I will then repeat the experiment again to see if I get the same results. It is becoming very enjoyable as much as it is being educational , and the best part is that we are getting the help that would allow us do it in the best scientific way we could Thanks and respects Athienah Athienah, I want to make sure we are on the same page.
Acidity levels, moisture, climate and preservatives are the four elements that determine how fast a loaf or slice of bread grows mold. With hard and semisoft cheese, you can cut away the moldy part and eat the rest of the cheese. The cake-contained more sugar than the bread, and sugar is used as a preservative. Mold starts out as spores, and the spores are the beginning of the life cycle for mold. Some cheeses, such as blue cheese, already contain mold when they are consumed.
